[codex] Add skills CLI and catalog management (#6782)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies through
company-scoped control-plane workflows.
> - Agents need reusable, inspectable skills that can be installed,
reset, audited, exported, and assigned without bespoke local setup.
> - The existing skill truth model needed cleanup so bundled skills,
optional catalog skills, runtime skills, and adapter-provided skills
have clear provenance.
> - Operators also need a practical CLI and board UI for discovering and
managing company skills.
> - This pull request adds the skills CLI, packaged skills catalog,
company skills APIs, and catalog-aware board UI.
> - The benefit is a more reusable Paperclip company setup where skills
are portable, auditable, and easier for operators and agents to manage.

## What Changed

- Added `paperclipai skills` CLI commands and coverage for catalog
listing, installing, resetting, and inspecting company skills.
- Added a packaged `@paperclipai/skills-catalog` workspace with bundled
and optional skill content plus validation/build tests.
- Added shared company-skill types and validators used across CLI,
server, and UI contracts.
- Added server catalog APIs/services for company skill catalog
operations, reset semantics, audit behavior, and portability provenance.
- Updated adapter skill handling so runtime/catalog provenance remains
explicit across local adapters.
- Added board UI support for browsing and managing catalog-backed
company skills.
- Updated docs for the skills CLI/catalog flow and the company skills
Paperclip skill reference.
- Rebased the branch onto current `paperclipai/paperclip:master`; no
`pnpm-lock.yaml`, `.github/workflows`, or migration files are included
in the final PR diff.

## Verification

- Passed: `pnpm run preflight:workspace-links && pnpm exec vitest run
cli/src/__tests__/skills.test.ts
packages/skills-catalog/src/catalog-builder.test.ts
packages/skills-catalog/src/shipped-catalog.test.ts
packages/shared/src/validators/company-skill.test.ts
packages/adapter-utils/src/server-utils.test.ts
packages/plugins/create-paperclip-plugin/src/entrypoints.test.ts
server/src/__tests__/company-skills-catalog-service.test.ts
server/src/__tests__/company-skills-routes.test.ts
server/src/__tests__/company-portability.test.ts`.
- Passed: `pnpm exec vitest run
server/src/__tests__/workspace-runtime.test.ts -t "default
branch|origin/master|symbolic-ref"`.
- Attempted: full `server/src/__tests__/workspace-runtime.test.ts`. Four
provisioning tests failed while seeding an isolated worktree database
from the local Paperclip instance because the local plugin schema dump
contains a duplicate-column foreign key
(`plugin_content_machine_18a7bc327b.content_case_signals`). The
default-branch tests touched by the rebase conflict passed in the
focused run above.
- Checked final diff: no `pnpm-lock.yaml`, no `.github/workflows`, and
no migration-file changes relative to `master`.

## Risks

- Medium: this is a broad skills/catalog change touching CLI, server
APIs, shared contracts, adapter skill sync, and UI.
- Catalog validation and reset semantics need careful reviewer attention
because they affect reusable company setup and portability.
- No database migrations are included in this PR, so there is no
migration ordering/idempotency risk in the final diff.
- No lockfile is included by design; dependency resolution will be
handled by the repository lockfile workflow.

## Model Used

- OpenAI Codex coding agent based on GPT-5, running in Paperclip via the
`codex_local` adapter with shell, git, GitHub CLI, and code-editing tool
access. Exact hosted model build/context-window metadata is not exposed
in this runtime.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have run targeted tests locally and documented the local
workspace-runtime seed failure above
- [x] I have added or updated tests where applicable
- [x] If this change affects the UI, screenshots were intentionally
omitted per PAP-10124 instructions; UI behavior is covered by tests and
reviewer inspection
- [x] I have updated relevant documentation to reflect my changes
- [x] I have considered and documented any risks above
- [x] I will address all Greptile and reviewer comments before
requesting merge

+## Skills Commands
+
+`paperclipai skills` covers three distinct operations:
+
+1. **Company install** — adds or updates a row in `company_skills` for the
+   whole company. This is what `skills install`, `skills import`, `skills create`,
+   and `skills scan-projects` do.
+2. **Agent attach** — replaces an agent's *desired* company skill set
+   (`skills agent sync`/`clear`). This is a desired-state operation on the
+   agent's adapter config; it does not change the company library.
+3. **Adapter runtime sync** — the adapter reconciles the desired skill set
+   with files on disk and reports an `AgentSkillSnapshot` (`skills agent list`).
+   `skills agent sync` triggers this automatically after updating desired state.
+
+Required Paperclip runtime skills (heartbeat, etc.) remain server-enforced and
+are added on top of whatever the desired set names.
+
+### Catalog (app-shipped skills)
+
+The Paperclip app ships a curated catalog under `@paperclipai/skills-catalog`.
+Browse and inspect commands never mutate company state; `install` adds a catalog
+skill to the company library.
+
+```sh
+pnpm paperclipai skills browse [--kind bundled|optional] [--category <slug>] [--query <text>]
+pnpm paperclipai skills search "<text>" [--kind bundled|optional] [--category <slug>]
+pnpm paperclipai skills inspect <catalog-id-or-key-or-slug>
+pnpm paperclipai skills install <catalog-id-or-key-or-slug> [--as <slug>] [--force] --company-id <company-id>
+```
+
+Catalog semantics:
+
+- **Bundled** skills live in `packages/skills-catalog/catalog/bundled/<category>/<slug>`
+  and are recommended defaults for most companies. They use canonical key
+  `paperclipai/bundled/<category>/<slug>`.
+- **Optional** skills live in `packages/skills-catalog/catalog/optional/<category>/<slug>`
+  and are role-specific or domain-specific (browser, AWS ops, etc.). Same key
+  shape with `optional` in place of `bundled`.
+- `skills install` materializes the catalog files into a company-managed skill
+  directory and records provenance (`catalogId`, `catalogKey`, `packageVersion`,
+  `originHash`, …) so future updates and audit decisions stay consistent.
+- `--as <slug>` overrides the company skill slug. `--force` may replace a
+  same-key catalog-managed skill but never bypasses hard validation or hard-stop
+  audit findings.
+
+Examples:
+
+```sh
+pnpm paperclipai skills browse --kind bundled --company-id <company-id>
+pnpm paperclipai skills search "pull request" --kind bundled
+pnpm paperclipai skills inspect github-pr-workflow
+pnpm paperclipai skills install github-pr-workflow --company-id <company-id>
+pnpm paperclipai skills install paperclipai:optional:browser:agent-browser --company-id <company-id>
+```
+
+External GitHub, skills.sh, local-path, and URL sources still go through
+`skills import`; catalog commands are for the app-shipped catalog only.
+
+### Company library
+
+```sh
+pnpm paperclipai skills list --company-id <company-id>
+pnpm paperclipai skills show <skill-id-or-key-or-slug> --company-id <company-id>
+pnpm paperclipai skills file <skill-id-or-key-or-slug> [--path SKILL.md] --company-id <company-id>
+pnpm paperclipai skills import <source> --company-id <company-id>
+pnpm paperclipai skills create --name "Review PRs" [--slug review-prs] [--description "..."] [--body-file SKILL.md] --company-id <company-id>
+pnpm paperclipai skills scan-projects [--project-id <id>...] [--workspace-id <id>...] --company-id <company-id>
+pnpm paperclipai skills check [skill-id-or-key-or-slug] --company-id <company-id>
+pnpm paperclipai skills update <skill-id-or-key-or-slug> [--force] --company-id <company-id>
+pnpm paperclipai skills update --all [--force] --company-id <company-id>
+pnpm paperclipai skills audit [skill-id-or-key-or-slug] --company-id <company-id>
+pnpm paperclipai skills reset <skill-id-or-key-or-slug> [--yes] [--force] --company-id <company-id>
+pnpm paperclipai skills remove <skill-id-or-key-or-slug> --yes --company-id <company-id>
+```
+
+`skills import <source>` accepts a skills.sh URL, the equivalent
+`<owner>/<repo>/<skill>` shorthand, a GitHub URL, a local path, or an
+`npx skills add …` command. See `references/company-skills.md` in the agent
+skill bundle for the source-type table.
+
+`skills check`, `skills update`, `skills audit`, and `skills reset` are the
+maintenance loop for catalog-installed skills:
+
+- `check` reports whether each skill's installed bytes match its pinned origin
+  (`hasUpdate`, `installedHash`, `originHash`, `updateHoldReason`,
+  `auditVerdict`).
+- `update` installs the pinned update through the existing install-update API.
+  `--all` checks every company skill and updates only those with
+  `hasUpdate=true`. `--force` discards local-modification or soft-audit holds;
+  hard-stop audit findings still block the update.
+- `audit` re-scans installed bytes and reports findings without executing
+  anything.
+- `reset` reinstalls a catalog-managed skill from its pinned origin, discarding
+  local edits. Prompts in a TTY; requires `--yes` for non-interactive use.
+
+### Agent attach
+
+```sh
+pnpm paperclipai skills agent list <agent-id-or-shortname> --company-id <company-id>
+pnpm paperclipai skills agent sync <agent-id-or-shortname> --skill <skill-id-or-key-or-slug> [--skill <skill-id-or-key-or-slug>...] --company-id <company-id>
+pnpm paperclipai skills agent clear <agent-id-or-shortname> --yes --company-id <company-id>
+```
+
+`skills agent sync` replaces the agent's non-required desired skill set (it is
+not additive) and returns the resulting adapter `AgentSkillSnapshot`.
+`skills agent clear` sends an empty desired list. Required Paperclip skills are
+still enforced by the server in both cases.
+
+### Notes
+
+- Skill references accept company skill `id`, canonical `key`, or unique
+  `slug`; catalog references accept catalog `id`, `key`, or unique `slug`.
+- `skills file` prints raw file content in human mode so it can be piped.
+- `skills create --body-file -` reads the skill markdown body from stdin.
+- `skills remove`, `skills reset`, and `skills agent clear` prompt in a TTY and
+  require `--yes` in non-interactive use.
+- `--json` prints the raw API result for each command.
+

 For project execution worktrees, Paperclip can also run a project-defined provision command after it creates or reuses an isolated git worktree. Configure this on the project's execution workspace policy (`workspaceStrategy.provisionCommand`). The command runs inside the derived worktree and receives `PAPERCLIP_WORKSPACE_*`, `PAPERCLIP_PROJECT_ID`, `PAPERCLIP_AGENT_ID`, and `PAPERCLIP_ISSUE_*` environment variables so each repo can bootstrap itself however it wants.
 
+## App-Shipped Skills Catalog
+
+The Paperclip app ships a curated catalog of company skills out of the box. The
+catalog is a workspace package at `packages/skills-catalog`:
+
+```text
+packages/skills-catalog/
+  catalog/
+    bundled/<category>/<slug>/SKILL.md   # recommended defaults
+    optional/<category>/<slug>/SKILL.md  # role/domain-specific
+  generated/catalog.json                  # checked-in manifest
+  scripts/
+    build-catalog-manifest.ts             # regenerate generated/catalog.json
+    validate-catalog.ts                   # validation only
+  src/                                    # builder + types consumed by server/CLI
+```
+
+Server and CLI import the generated manifest; they do not crawl repository
+paths at request time. Root `skills/` remains reserved for Paperclip runtime
+skills and is not part of the catalog.
+
+Validate the catalog without writing the manifest:
+
+```sh
+pnpm --filter @paperclipai/skills-catalog validate
+```
+
+Regenerate `generated/catalog.json` after editing any catalog `SKILL.md`,
+frontmatter, file inventory, category, or slug:
+
+```sh
+pnpm --filter @paperclipai/skills-catalog build:manifest
+```
+
+The package's `build` script runs `build:manifest` and then `tsc`; tests live
+under `pnpm --filter @paperclipai/skills-catalog test`. Validation fails when:
+
+- a catalog entry is not under `catalog/bundled/<category>/<slug>` or
+  `catalog/optional/<category>/<slug>`
+- `SKILL.md` is missing or the frontmatter `name`/`description` is empty
+- the frontmatter `key` disagrees with the generated canonical key
+- two catalog entries share an `id`, `key`, or `slug`
+- file inventory contains absolute paths, `..`, broken symlinks, or files
+  outside the skill directory
+- the regenerated manifest differs from the checked-in
+  `generated/catalog.json`
+
+Trust level is derived from inventory: `markdown_only` (markdown + references
+only), `assets` (other non-script files), or `scripts_executables` (any
+executable script). The build contract is documented in
+`doc/plans/2026-05-26-skills-cli-catalog-contract.md`.
+
+CI runs `pnpm --filter @paperclipai/skills-catalog validate` and the package's
+vitest suite, so always regenerate the manifest in the same commit as the
+catalog change.

+# Skills CLI And Catalog Contract
+
+Status: Phase A engineering contract
+Date: 2026-05-26
+Source plan: approved Paperclip skills CLI and catalog plan
+
+This document freezes the first implementation contract for the `paperclipai skills`
+command group and the app-shipped skills catalog. It is intentionally a build
+contract, not a full product spec.
+
+## Decisions
+
+- `paperclipai skills` manages Paperclip company skills. It does not manage
+  local adapter homes directly.
+- Installing a skill means adding or updating a company-scoped
+  `company_skills` record.
+- Attaching a skill to an agent is a separate agent desired-state operation.
+- Adapter runtime sync is a third step handled through adapter skill APIs.
+- Root `skills/` remains reserved for Paperclip runtime and operational skills.
+- App-shipped catalog skills live in `packages/skills-catalog`, not root
+  `skills/`.
+- Catalog skills are inspectable before install. Inspection never mutates company
+  state.
+- External sources continue to use the existing company skill import API in the
+  first release. No separate marketplace, tap, or source registry is part of this
+  phase.
+- Agent desired skills continue to live in
+  `adapterConfig.paperclipSkillSync.desiredSkills` for the first release. Do not
+  add a normalized `agent_skills` table unless later implementation evidence
+  requires it.
+
+## Terms
+
+- Company skill: a row in `company_skills`, owned by one company.
+- Catalog skill: an app-shipped skill entry in `@paperclipai/skills-catalog`.
+- Skill ref: a user-supplied company skill reference. The CLI accepts company
+  skill `id`, canonical `key`, or unique `slug`.
+- Catalog ref: a user-supplied catalog reference. The CLI accepts catalog `id`,
+  canonical `key`, or unique `slug`.
+- Desired skills: the skill key set stored on the agent adapter config.
+- Runtime snapshot: the adapter-reported `AgentSkillSnapshot` for desired,
+  installed, missing, stale, external, required, or unsupported skills.
+
+## CLI Contract
+
+All skills commands use the existing client command stack:
+
+- Global client options: `--data-dir`, `--config`, `--context`, `--profile`,
+  `--api-base`, `--api-key`, and `--json`.
+- Company-scoped commands also accept `-C, --company-id <id>` and otherwise use
+  `PAPERCLIP_COMPANY_ID` or the active context profile.
+- Human output goes to stdout. Errors go to stderr.
+- `--json` prints pretty JSON and no decorative labels.
+- Successful commands exit `0`. Validation, API, or conflict errors exit `1`.
+- API errors use the existing `API error <status>: <message>` formatting.
+- Mutating commands print a short summary in human mode and the raw result in
+  JSON mode.
+- Commands that can delete or clear state must prompt in a TTY. In non-TTY mode
+  they must require `--yes`.
+
+### Company Skill Commands
+
+These commands are Phase B and must work over existing APIs.
+
+| Command | Behavior | JSON output |
+|---|---|---|
+| `skills list` | Lists company skills from `GET /api/companies/:companyId/skills`. Human rows include `id`, `key`, `slug`, `name`, `source`, `trust`, `compatibility`, and `attachedAgents`. | `CompanySkillListItem[]` |
+| `skills show <skill-ref>` | Resolves `id`, `key`, or unique `slug`, then reads detail. Ambiguous slugs are conflicts. | `CompanySkillDetail` |
+| `skills file <skill-ref> [--path <path>]` | Resolves the skill, reads a file with default `SKILL.md`, and prints raw file content in human mode. This command must remain pipeable. | `CompanySkillFileDetail` |
+| `skills import <source>` | Calls existing import API. Source may be a local path, GitHub URL, skills.sh URL or command, `owner/repo`, `owner/repo/skill`, or URL-like source already accepted by the server. | `CompanySkillImportResult` |
+| `skills create --name <name> [--slug <slug>] [--description <text>] [--body-file <path|->]` | Creates a managed local company skill. If `--body-file` is omitted, the server default body is used. `-` reads markdown from stdin. | `CompanySkill` |
+| `skills scan-projects [--project-id <id>...] [--workspace-id <id>...]` | Calls project scan. Repeated flags become arrays. With neither flag, scan all accessible project workspaces. | `CompanySkillProjectScanResult` |
+| `skills check [skill-ref]` | Reads update status for one skill, or for every listed company skill when no ref is provided. Unsupported statuses are shown, not hidden. | `CompanySkillCheckRow[]` |
+| `skills update <skill-ref>` | Installs the update for one skill through the existing install-update API. | `CompanySkillUpdateRow` |
+| `skills update --all` | Checks all skills, installs only those with `hasUpdate=true`, and reports skipped unsupported or current skills. | `CompanySkillUpdateRow[]` |
+| `skills remove <skill-ref> [--yes]` | Deletes one company skill after confirmation. | `CompanySkill` |
+
+`CompanySkillCheckRow` is a CLI-side shape:
+
+```ts
+interface CompanySkillCheckRow {
+  skill: Pick<CompanySkillListItem, "id" | "key" | "slug" | "name">;
+  status: CompanySkillUpdateStatus;
+}
+```
+
+`CompanySkillUpdateRow` is a CLI-side shape:
+
+```ts
+interface CompanySkillUpdateRow {
+  skillRef: string;
+  action: "updated" | "skipped" | "failed";
+  skill?: CompanySkill;
+  status?: CompanySkillUpdateStatus;
+  reason?: string;
+}
+```
+
+### Agent Skill Commands
+
+These commands are Phase B and use existing agent skill APIs.
+
+| Command | Behavior | JSON output |
+|---|---|---|
+| `skills agent list <agent-ref>` | Resolves the agent using existing agent reference behavior, then prints the adapter `AgentSkillSnapshot`. Human rows include `key`, `runtimeName`, `desired`, `managed`, `required`, `state`, `origin`, and `detail`. | `AgentSkillSnapshot` |
+| `skills agent sync <agent-ref> --skill <skill-ref>...` | Replaces the agent's non-required desired skill set with the supplied refs and triggers adapter sync. Required Paperclip skills remain enforced by the server. | `AgentSkillSnapshot` |
+| `skills agent clear <agent-ref> [--yes]` | Clears non-required desired skills by sending an empty desired list, then returns the adapter snapshot. | `AgentSkillSnapshot` |
+
+The word `sync` is deliberate: it is a desired-state replacement, not an append.
+An additive command can be added later if operators need it.
+
+### Catalog CLI Commands
+
+These commands are Phase E and depend on the catalog APIs from Phase D.
+
+| Command | Behavior | JSON output |
+|---|---|---|
+| `skills browse [--kind bundled|optional] [--category <slug>] [--query <text>]` | Lists app-shipped catalog skills. Human rows include `id`, `key`, `kind`, `category`, `slug`, `name`, `trust`, and `recommendedForRoles`. | `CatalogSkillListItem[]` |
+| `skills search <query> [--kind bundled|optional] [--category <slug>]` | Alias for catalog browse with `query`. | `CatalogSkillListItem[]` |
+| `skills inspect <catalog-ref>` | Shows app-shipped catalog detail and file inventory. Does not mutate company state. | `CatalogSkillDetail` |
+| `skills install <catalog-ref> [--as <slug>] [--force]` | Installs a catalog skill into a company library. `--as` overrides the company skill slug. `--force` may replace a same-key catalog skill but must not bypass hard validation or dangerous security findings. | `CompanySkillInstallCatalogResult` |
+
+Catalog commands are for the app-shipped Paperclip catalog only. External GitHub,
+skills.sh, local path, and URL installs remain under `skills import <source>` in
+the first release.
+
+## Catalog Package Contract
+
+Add a workspace package:

+
+- `catalogManifest`
+- `catalogSkills`
+- `resolveCatalogSkillRef(ref)`
+- `getCatalogSkill(id)`
+- TypeScript types for every manifest shape
+
+Server and CLI code must import the generated manifest. They must not crawl
+arbitrary repository paths at request time.
+
+## Catalog Manifest
+
+The generated artifact is `packages/skills-catalog/generated/catalog.json`.
+It is checked in and regenerated by the package build or validation script.
+
+```ts
+interface CatalogManifest {
+  schemaVersion: 1;
+  packageName: "@paperclipai/skills-catalog";
+  packageVersion: string;
+  generatedAt: string;
+  skills: CatalogSkill[];
+}
+
+interface CatalogSkill {
+  id: string;
+  key: string;
+  kind: "bundled" | "optional";
+  category: string;
+  slug: string;
+  name: string;
+  description: string;
+  path: string;
+  entrypoint: "SKILL.md";
+  trustLevel: "markdown_only" | "assets" | "scripts_executables";
+  compatibility: "compatible" | "unknown" | "invalid";
+  defaultInstall: boolean;
+  recommendedForRoles: string[];
+  requires: string[];
+  tags: string[];
+  files: CatalogSkillFile[];
+  contentHash: string;
+}
+
+interface CatalogSkillFile {
+  path: string;
+  kind: "skill" | "markdown" | "reference" | "script" | "asset" | "other";
+  sizeBytes: number;
+  sha256: string;
+}
+```
+
+`id` is path-safe:
+
+```text
+paperclipai:<kind>:<category>:<slug>
+```
+
+`key` is the canonical company skill key installed into `company_skills`:
+
+```text
+paperclipai/<kind>/<category>/<slug>
+```
+
+Example:
+
+```json
+{
+  "id": "paperclipai:bundled:software-development:github-pr-workflow",
+  "key": "paperclipai/bundled/software-development/github-pr-workflow",
+  "kind": "bundled",
+  "category": "software-development",
+  "slug": "github-pr-workflow",
+  "name": "github-pr-workflow",
+  "description": "Prepare pull requests, review responses, and verification notes.",
+  "path": "catalog/bundled/software-development/github-pr-workflow",
+  "entrypoint": "SKILL.md",
+  "trustLevel": "markdown_only",
+  "compatibility": "compatible",
+  "defaultInstall": false,
+  "recommendedForRoles": ["engineer"],
+  "requires": [],
+  "tags": ["github", "pull-requests"],
+  "files": [
+    {
+      "path": "SKILL.md",
+      "kind": "skill",
+      "sizeBytes": 1200,
+      "sha256": "..."
+    }
+  ],
+  "contentHash": "sha256:..."
+}
+```
+
+## Catalog Skill Frontmatter
+
+Each catalog `SKILL.md` must include:
+
+```yaml
+---
+name: github-pr-workflow
+description: Prepare pull requests, review responses, and verification notes.
+key: paperclipai/bundled/software-development/github-pr-workflow
+recommendedForRoles:
+  - engineer
+tags:
+  - github
+  - pull-requests
+---
+```
+
+Optional frontmatter:
+
+- `slug`
+- `defaultInstall`
+- `requires`
+- `metadata`
+
+The manifest generator owns `kind`, `category`, `path`, `files`,
+`trustLevel`, `compatibility`, and `contentHash`.
+
+## Catalog Validation Rules
+
+Validation must fail when:
+
+- A catalog entry is not under `catalog/bundled/<category>/<slug>` or
+  `catalog/optional/<category>/<slug>`.
+- `SKILL.md` is missing.
+- `category` or `slug` is not a lowercase URL slug.
+- `name` or `description` frontmatter is missing or empty.
+- The frontmatter `key`, when present, does not equal the generated key.
+- Two catalog entries have the same `id`, `key`, or `slug`.
+- File inventory includes absolute paths, `..` segments, broken symlinks, or
+  files outside the skill directory.
+- A file exceeds the package-level size limit chosen by implementation.
+- A skill marked `compatible` cannot be parsed as Agent Skills markdown.
+- The generated manifest differs from the checked-in
+  `generated/catalog.json`.
+
+Trust level is derived from inventory:
+
+- `scripts_executables` when any file is classified as `script`.
+- `assets` when any file is classified as `asset` or `other` and no script is
+  present.
+- `markdown_only` when all files are markdown, references, or `SKILL.md`.
+
+Validation must report all discovered catalog errors when practical, not just
+the first one.
+
+## Catalog API Contract
+
+Phase D adds read APIs and one company install API.
+
+```text
+GET  /api/skills/catalog
+GET  /api/skills/catalog/:catalogId
+GET  /api/skills/catalog/:catalogId/files?path=SKILL.md
+POST /api/companies/:companyId/skills/install-catalog
+```
+
+`GET /api/skills/catalog` accepts:
+
+- `kind=bundled|optional`
+- `category=<slug>`
+- `q=<text>`
+
+`catalogId` is the path-safe manifest `id`. The server should also support
+resolution by `key` or unique `slug` where the ref is carried in a query or body,
+but route parameters use `id` to avoid slash handling ambiguity.
+
+Install request:
+
+```ts
+interface CompanySkillInstallCatalogRequest {
+  catalogSkillId: string;
+  slug?: string | null;
+  force?: boolean;
+}
+```
+
+Install result:
+
+```ts
+interface CompanySkillInstallCatalogResult {
+  action: "created" | "updated" | "unchanged";
+  skill: CompanySkill;
+  catalogSkill: CatalogSkill;
+  warnings: string[];
+}
+```
+
+Install behavior:
+
+- Creates or updates a company skill with `sourceType="catalog"`.
+- Uses catalog `key` as the company skill canonical key.
+- Uses catalog `slug` unless `slug` is provided.
+- Materializes the catalog files into a company-managed skill directory so
+  existing skill file reads continue to work.
+- Stores provenance in metadata:
+  - `catalogId`
+  - `catalogKey`
+  - `catalogKind`
+  - `catalogCategory`
+  - `catalogPath`
+  - `packageName`
+  - `packageVersion`
+  - `originHash`
+  - `originVersion`
+  - `userModifiedAt`
+  - `updateHoldReason`
+- Writes activity log entries for install and update.
+- Returns `409` for duplicate slug/key conflicts that cannot be resolved safely.
+- Returns `422` for invalid, incompatible, or hard-blocked catalog entries.
+- `force` may replace a same-key catalog-managed skill. It must not bypass
+  company boundaries, permission checks, hard validation, or hard security
+  findings.
+
+## Error Semantics
+
+Use existing HTTP semantics:
+
+- `400`: invalid CLI arguments, invalid query/body shape, or malformed refs.
+- `401`: missing or invalid auth.
+- `403`: authenticated principal lacks access or mutation permission.
+- `404`: skill, catalog entry, agent, file, company, or source not found.
+- `409`: ambiguous slug, duplicate key/slug, update conflict, or unsafe overwrite.
+- `422`: semantic violation such as invalid skill content or unsupported source.
+- `500`: unexpected server failure.
+
+CLI messages should name the next useful correction, for example:
+
+- `Skill slug "review" is ambiguous. Use an id or key.`
+- `Company ID is required. Pass --company-id, set PAPERCLIP_COMPANY_ID, or set a context profile.`
+- `Catalog skill contains executable scripts and cannot be force-installed until security review semantics allow it.`
+
+## Phase Acceptance Criteria
+
+Phase A is complete when this contract is available in the repo and the issue
+thread links it.
+
+Phase B, CLI MVP:
+
+- `paperclipai skills --help` exposes the Phase B command group.
+- All Phase B commands work against existing company skills and agent skills
+  APIs without schema or server changes.
+- Skill refs resolve by id, key, or unique slug.
+- Human and JSON output are covered by focused CLI tests.
+- `doc/CLI.md` documents company install vs agent desired sync vs runtime sync.
+
+Phase C, catalog package:
+
+- `packages/skills-catalog` is a workspace package.
+- Build or validation regenerates `generated/catalog.json`.
+- Validation covers frontmatter, id/key/slug uniqueness, directory shape, file
+  inventory, trust derivation, and stale generated output.
+- Server and CLI can import the manifest without crawling arbitrary paths.
+- Root `skills/` is not expanded with the app-shipped catalog.
+
+Phase D, catalog APIs:
+
+- Catalog list/detail/file APIs are read-only and covered by tests.
+- Install-from-catalog creates auditable company-scoped skill records with
+  provenance metadata and materialized files.
+- Company boundary and mutation permission checks match or exceed existing
+  company skill mutations.
+- Duplicate and unsafe overwrite behavior is explicit and tested.
+
+Phase E, catalog CLI:
+
+- Operators can browse, search, inspect, and install app-shipped catalog skills.
+- External source behavior remains routed through `skills import`.
+- Output and errors follow the Phase B CLI conventions.
+- Catalog install is clearly distinct from agent attach/sync in help and docs.
+
+Phase F, update/reset/audit:
+
+- Security review records decisions for origin hash, user modification detection,
+  reset, audit findings, and force behavior.
+- Implementation follows the review or records explicit deferrals.
+- Mutating reset/update actions are activity logged.
+- Tests cover dangerous findings, force behavior, and unchanged/current states.
+
+Phase G, adapter truth model:
+
+- Adapter snapshots accurately report `unsupported`, `persistent`, or
+  `ephemeral`.
+- Desired, missing, installed, stale, external, and required states are tested.
+- External adapter plugins remain dynamically loaded. No hardcoded plugin imports
+  are added.
+
+Phase H, UI:
+
+- The existing Company Skills page is extended rather than replaced.
+- UX guidance covers Company, Bundled, Optional, and External source views.
+- Install preview shows source, trust, provenance, update state, and file
+  inventory.
+- Agent attach/detach states are clear.
+- Frontend handoff includes screenshots or equivalent browser evidence.
+
+Phase I, initial skill content:
+
+- Bundled and optional entries use the finalized frontmatter and category rules.
+- Skill descriptions are specific enough for browse/search.
+- No script-bearing skill lands without explicit security review evidence.
+- Validation fixtures or tests cover representative content.
+
+Phase J, QA and docs:
+
+- QA validates CLI, catalog APIs, UI install, agent sync, portability, and adapter
+  snapshots against a dev instance.
+- Blocking defects are linked as first-class issues.
+- `doc/CLI.md`, `doc/DEVELOPING.md`, and skill workflow docs match shipped
+  behavior.
+
+## Deferrals
+
+- No cloud marketplace.
+- No user-home tap registry.
+- No hidden curator or autonomous catalog mutator.
+- No normalized `agent_skills` table in the first release.
+- No skill sets or bundles in the first release.
+- No automatic install of every optional catalog skill.
+- No replacement of company import/export as the portability path.

+
+# Doc Maintenance
+
+Keep the documentation honest with minimum churn. The goal is alignment between docs and behavior, not stylistic rewrites or cosmetic re-organization. Reviewers should be able to read a diff and see "this updates docs to match recent behavior changes".
+
+## When to use
+
+- A PR or recent set of merges changed user-visible behavior: CLI flags, API shapes, default values, configuration keys, endpoints, environment variables, supported versions.
+- A user-reported bug traced back to outdated documentation.
+- A release is being cut and the docs need a pass against the merged commits.
+- A new feature shipped but only the engineer's PR description describes how to use it.
+
+## When not to use
+
+- The change is internal-only (private helper rename, refactor) with no user-visible impact.
+- You want to "improve the docs" without a behavior anchor. That is a separate scoped project, not maintenance — make a plan first.
+
+## The pass
+
+1. **Establish the baseline.** Get the commit range you are documenting against (since last release tag, since last merged-doc commit, or since a specific PR).
+2. **Enumerate user-visible changes.** Read commits and PR descriptions. List, for each change, what a user can now do differently.
+3. **Map changes to docs.** For each change, find every page that mentions the affected concept. Common targets: README, CLI reference, API reference, configuration reference, migration guide, FAQ, examples.
+4. **Update precisely.** Edit only the lines that need to change. Do not rewrap paragraphs you did not modify — it pollutes the diff.
+5. **Add new entries where needed.** New CLI flag → CLI reference entry. New env var → configuration reference entry. New endpoint → API reference entry. Don't only add it to the changelog.
+6. **Update examples and snippets.** Code blocks in docs are wrong faster than prose. Re-run any example that touches new behavior.
+7. **Write the release note.** One sentence per user-visible change. Group by Added / Changed / Fixed / Deprecated / Removed. Link to the relevant PRs and docs section.
+8. **Cross-check.** Search the docs for the old behavior wording and remove or update stragglers.
+
+## Style baseline
+
+- Voice: second person ("you can pass `--json` to ..."). Avoid "we" except in narrative pages.
+- Tense: present, not future. The behavior exists once shipped.
+- Headings: imperative ("Configure the cache") or noun-phrase ("Cache configuration"), match the surrounding page.
+- Code blocks: include the language tag so syntax highlighting works.
+- Cross-links: link the first mention of a concept on each page; do not link every occurrence.
+- Avoid promising future behavior. If something is unreleased, mark it `experimental` or omit it.
+
+## Drift detection
+
+A doc page is drifting if any of these are true:
+
+- It documents a flag, key, or endpoint that no longer exists.
+- An example does not run as written.
+- A default value in the docs does not match the code.
+- A supported-versions list excludes a version the project actually supports, or includes one it dropped.
+- A "Coming soon" section references a feature that shipped or was cancelled.
+
+When you find drift, fix it in the same pass and note it in the release note's `Fixed` group.
+
+## Release-note rules
+
+- One sentence per item. If two sentences are needed, the item is likely two items.
+- User impact first, internal cause second. `Faster cold start (avoid full bundle download on first run)` beats `Refactor bootstrap loader`.
+- Link the PR for engineering readers and the docs page for users.
+- Mark breaking changes explicitly: `**Breaking:**` prefix. Include migration steps inline or via link.
+
+## Anti-patterns
+
+- Massive doc PRs that bundle stylistic rewrites with real updates. Reviewers cannot tell which lines reflect actual behavior changes.
+- "Updated docs" commit messages with no detail. Make the commit say what changed and why.
+- Adding to the changelog without updating the reference docs the changelog points to.
+- Marking a feature as available before its code lands. Documentation must follow behavior, not promise it.

+- You are checked out on one specific issue and the wake context names it. Work that issue, do not triage the whole inbox.
+- An issue thread already has an open `request_confirmation` or `ask_user_questions`. Wait for the response — re-triage is noise.
+
+## Inputs
+
+- `GET /api/agents/me/inbox-lite` for the compact assignment list.
+- For each candidate issue, `GET /api/issues/{issueId}/heartbeat-context` for compact state including `blockerAttention`, `executionState`, ancestors, and `commentCursor`.
+- Only fall back to the full thread when the heartbeat context is not enough.
+
+## Per-issue triage decision
+
+For each issue, classify into exactly one of:
+
+1. **Resume** — execution path is alive. Confirm the assignee is set and let the heartbeat continue. Do not comment.
+2. **Wake-needed** — assignee is stalled with no live continuation. Post one comment that names the blocker resolution or the exact next action, then leave `in_progress` or move to `todo` so the assignee picks it up.
+3. **Reassign** — the assignee is not the right specialty. Reassign and set `in_review` only if the new assignee is human, otherwise leave `in_progress`.
+4. **Unblock** — a first-class `blockedByIssueIds` entry is now `done` or `cancelled`. If `cancelled`, replace or remove it from `blockedByIssueIds`. The blockers-resolved wake will fire automatically when all are `done`.
+5. **Escalate** — the issue needs board, CTO, or user input. Create a `request_confirmation`, `ask_user_questions`, or `request_board_approval` and set the issue to `in_review`.
+6. **Close** — work is complete, duplicate, or no longer relevant. Set `done` or `cancelled` with a one-line reason.
+
+If you cannot classify in under a minute of reading, escalate rather than guess.
+
+## Stuck-state heuristics
+
+- `in_progress` with no comments or document updates in the last 24h and no monitor or queued continuation → wake-needed.
+- `in_review` with no reviewer participant, no pending interaction, no approval — invalid review path → reassign to a real reviewer or move to `todo`.
+- `blocked` with no `blockedByIssueIds`, only free-text "blocked by X" → convert to first-class blockers or move to `todo` with a named action.
+- `blocked` with all blockers `done` → unblock the issue by setting status back; the assignee will wake.
+- Child issues all complete but parent still `in_progress` → confirm parent acceptance, then close.
+
+## Don't-do list
+
+- Do not @-mention agents during triage; mentions cost budget. Use direct reassignment instead.
+- Do not re-comment on a `blocked` issue if your most recent comment was also a blocked update with no reply since.
+- Do not cancel cross-team issues. Reassign to the responsible manager with a comment.
+- Do not change status without a comment that explains the change.
+
+## Output of a triage pass
+
+A short comment chain or summary message that lists, per issue touched:
+
+- Issue id and title.
+- Verdict (resume / wake-needed / reassign / unblock / escalate / close).
+- The one action you took or asked for.
+
+This is the bar for "the triage is done."

+
+# Task Planning
+
+Produce implementation plans that the Paperclip executor can actually run: explicit child issues, real blockers, named owners, and a defined acceptance bar. Avoid plans that read well but cannot be split into work.
+
+## When to use
+
+- An issue asks you to "plan", "scope", "break down", "design the rollout", "propose the work", or similar.
+- A user wants a written plan before approving implementation.
+- A manager needs to delegate non-trivial work and the shape of the work is not obvious yet.
+- You inherited an issue too large to deliver in one heartbeat and need to split it.
+
+## When not to use
+
+- The issue is a single small change you can ship in the same heartbeat. Just ship it.
+- The issue is forensic ("why did this break"). Use a diagnosis skill first; plan only after the root cause is named.
+- A current `plan` document already exists and the change is minor. Update that document; do not start fresh.
+
+## Outputs
+
+1. An updated issue document with key `plan` (markdown).
+2. A short comment on the issue that links to the plan document and names the next action.
+3. Where the plan requires approval, an issue-thread interaction of kind `request_confirmation` bound to the latest plan revision.
+
+Do not create implementation subtasks until the plan is accepted.
+
+## Plan structure
+
+Required sections, in order:
+
+1. **Goal** — one paragraph. What changes for the user, the operator, or the system once this work lands.
+2. **Context reviewed** — bullet list of documents, files, and prior issues you read. Lets reviewers spot missing inputs.
+3. **Constraints and non-goals** — what must hold (compatibility, security, performance) and what this plan deliberately will not do.
+4. **Approach** — the chosen path, with a short rationale. If you considered alternatives, name them and why you rejected them.
+5. **Work breakdown** — ordered list of child issues. Each child has:
+   - Title in imperative form.
+   - Owner specialty (Engineer, QA, Designer, Security, DevRel, Manager, etc.).
+   - Scope and deliverables.
+   - Acceptance criteria.
+   - Blocks/blocked-by relationships expressed by phase letter or child title.
+6. **Acceptance** — the bar for the parent issue. How the user knows the whole thing is done.
+7. **Risks and mitigations** — short list. Skip if there are none.
+8. **Deferrals** — what is intentionally pushed to follow-up issues, with why.
+
+## Rules of thumb for splitting
+
+- One child issue, one specialty. If two specialties have to coordinate inside the same issue, split it.
+- One child issue, one acceptance verdict. If a reviewer would say "this is half done", split it.
+- A child must be checkout-able by the owner from its title and description alone. Reviewers should not have to re-read the parent plan to understand a child.
+- Order children by real blocker chains, not by author preference. Parallel children should explicitly say `blockers: none`.
+- Avoid `polish` or `cleanup` child issues without acceptance criteria — they never close.
+
+## Filing the plan
+
+Use the Paperclip API to write the plan document, then comment:
+
+- `PUT /api/issues/{issueId}/documents/plan` with the markdown body. If `plan` already exists, include the latest `baseRevisionId`.
+- `POST /api/issues/{issueId}/comments` with a short summary that links the plan: `/<prefix>/issues/<issue-id>#document-plan`.
+- If approval is required: `POST /api/issues/{issueId}/interactions` with `kind: request_confirmation`, `targetRevisionId` set to the new plan revision, `continuationPolicy: wake_assignee`, and `idempotencyKey: "confirmation:{issueId}:plan:{revisionId}"`.
+- Set the issue to `in_review` after creating the confirmation. Stay assigned so the acceptance wakes the planner.
+
+When the plan is accepted, see the companion skill for converting accepted plans into Paperclip executable tasks.
+
+## Anti-patterns
+
+- Plan disguised as a description edit. Use the `plan` document.
+- "Phases A–Z" with no work breakdown inside the phases.
+- Children with descriptions that say "see parent" — they fail at delegation time.
+- Acceptance written as "code review approval". Reviewers need a behavior bar, not a process bar.
+- Plans that bury blocker chains in prose. Use explicit blocked-by lines.

+
+# QA Acceptance
+
+Write acceptance criteria that a reviewer can run against the running app and decide pass or fail without asking the author. The criteria are the contract — automated tests cover correctness, QA covers feature-level behavior.
+
+## When to use
+
+- A feature change is heading to QA and needs a written validation plan.
+- A reviewer is asked to verify a PR that touches user-visible behavior.
+- An incident postmortem requires a regression check before reopen-prevention.
+- A release candidate needs a pre-cut smoke pass.
+
+## When not to use
+
+- The change is unit-test-only (utility refactor, internal naming). Acceptance criteria are unnecessary churn.
+- You are asked to write tests against API contracts. Use contract testing, not feature QA.
+
+## Acceptance criteria format
+
+Each criterion is a single, independently-verifiable statement:
+
+```md
+- **Given** <starting state>, **when** <action>, **then** <observable outcome>.
+```
+
+Example:
+
+```md
+- **Given** a CSV export with 0 rows, **when** the user clicks Export, **then** the file downloads with only the header row and the UI shows "Exported 0 rows".
+```
+
+Avoid criteria that combine multiple `when`s or `then`s. Split them.
+
+## What every plan must cover
+
+1. **Golden path.** The most common successful flow, end to end.
+2. **Empty and minimum states.** Zero items, one item, missing optional inputs.
+3. **Boundary inputs.** Max length strings, max numeric values, unicode, RTL text where applicable.
+4. **Error states.** Network failure, permission denied, validation failures, conflict (409), not found (404).
+5. **Concurrency and ordering.** Two users acting at once, race against background jobs, refresh during mutation.
+6. **Performance envelope.** The largest realistic input the change must handle without UI hangs or timeouts.
+7. **Backward compatibility.** Existing data, existing URLs, persisted user preferences continue to work.
+8. **Telemetry and audit.** Events, logs, or activity entries the change is supposed to emit.
+
+If a section is genuinely not applicable, write "N/A: <why>" — do not silently omit.
+
+## Evidence
+
+Each criterion needs evidence on the verification pass:
+
+- Screenshot or short clip for UI behavior.
+- Copied console / network output for API behavior.
+- Log snippet or activity row for telemetry.
+- Timing measurement for performance criteria.
+
+"Looks good to me" without evidence is not a pass.
+
+## Quarantine and follow-up
+
+- A failing criterion blocks acceptance unless explicitly waived by the owner with a tracked follow-up issue.
+- "Known issue" without a linked follow-up is not a waiver.
+- If you add a new criterion mid-pass, restart the pass — partial coverage hides regressions.
+
+## Handoff back to the author
+
+Return the validation plan with three sections:
+
+- **Pass.** Criteria that passed, with one-line evidence summaries.
+- **Fail.** Criteria that failed, with the exact reproduction.
+- **Blocked.** Criteria you could not run, with why.
+
+The author owns turning failures into either fixes or accepted deferrals.
+
+## Anti-patterns
+
+- Acceptance phrased as test plan ("write a Cypress test for X"). Acceptance is what is true after the change ships; tests are how you check.
+- Criteria that depend on inspecting implementation details (selectors, query plans). Stay observable.
+- Long checklists with no priority. Mark must-pass criteria distinctly from nice-to-have.
+- Validation reports that say "passed" with no evidence. Reviewers cannot audit those.

+
+# GitHub Pull Request Workflow
+
+Ship a PR a reviewer can land without follow-up clarifying questions. The aim is high signal in the title and body, evidence the change works, and clean replies when feedback comes in.
+
+## When to use
+
+- You are about to open a PR for a change that is functionally complete.
+- A reviewer left comments and you need to respond and push fixes.
+- A PR has been open more than a day and needs to be brought back into shape (stale conflicts, missing description, missing verification).
+
+## When not to use
+
+- The change is not yet functionally complete. Finish the work first; draft PRs that bounce on review are noise.
+- The repository uses a non-GitHub forge. Adjust to that forge's conventions; do not force GitHub-isms.
+
+## Branch hygiene before opening
+
+- Rebase or merge from the target base so the diff is current.
+- Squash WIP commits into reviewable units. Prefer one commit per logical change; do not force one-commit-per-PR if the work is genuinely multi-step.
+- Confirm tests, typecheck, and lint pass locally. Note any deliberate skips in the PR body.
+- Remove debug prints, commented-out code, and `TODO` markers that are not tracked.
+
+## PR title
+
+- Imperative mood, under 70 characters.
+- Lead with the user-visible change, not the file touched. `Allow CSV export from reports table` beats `Update reports.tsx`.
+- If the repo uses an issue prefix convention (`PAP-1234:`, `[security]`), follow it.
+- No trailing period.
+
+## PR body
+
+Use this structure:
+
+```md
+## Summary
+- 1–3 bullets describing what changed and why.
+
+## Implementation notes
+- Anything non-obvious in the diff: trade-offs, dropped alternatives, gotchas.
+- Migration or config implications.
+
+## Verification
+- The exact commands or steps you ran.
+- Screenshots or short clips for UI changes (required if pixels moved).
+- Edge cases you exercised by hand.
+
+## Risk and rollback
+- What breaks if this is reverted, and how to revert cleanly.
+```
+
+Skip the `Risk and rollback` section only for clearly trivial PRs (typos, docs).
+
+## Verification evidence
+
+- Tests passing in CI is necessary, not sufficient. Reviewers also need to know the change behaves correctly end to end.
+- For UI work, include screenshots of the golden path and one edge case. Tag dark and light mode if the project supports both.
+- For migrations, include a dry-run plan and reversal steps.
+- For performance changes, include a before/after measurement, not adjectives.
+
+## Replying to review comments
+
+- Reply on every comment, even with just "fixed in <commit-sha>" — silent fixes leave the reviewer guessing.
+- Push fixes as new commits while review is active; do not amend during review unless the reviewer agrees.
+- If you disagree with feedback, say so with one sentence of rationale and let the reviewer decide. Don't escalate over comments.
+- Re-request review explicitly after pushing changes.
+
+## Merge checklist
+
+- All required checks green.
+- All review comments resolved.
+- PR title/body still accurate (update if scope changed mid-review).
+- Linked issue moves to `in_review` or `done` per project convention.
+- Delete the branch after merge unless it is a long-lived integration branch.
+
+## Anti-patterns
+
+- PR description that says "see commits". Reviewers should not need to read the log.
+- Mixing refactor and behavior change in the same PR with no separation in the body.
+- "Address feedback" commits that bundle unrelated edits. One commit per round of feedback is fine; one commit for everything in flight is not.
+- Force-pushing during active review without telling the reviewer.

+# Agent Browser
+
+Use a controlled browser to verify behavior, capture evidence, or extract information from web pages that a static fetch cannot reach (SPAs, login-gated pages, dynamic content). This skill is about supervised verification, not unattended scraping.
+
+## When to use
+
+- You need a screenshot of a deployed page or a local dev server to confirm a UI change.
+- You need to read JavaScript-rendered content that `curl`/`wget` will not see.
+- A user reports a UI bug and you need to reproduce it interactively to capture console errors, network requests, or layout state.
+- You need to walk through a short flow (load page, click, observe) to verify acceptance criteria.
+
+## When not to use
+
+- The page is reachable as static HTML. Use `curl`/HTTP fetch — it is cheaper, faster, and more reliable.
+- The task is unattended large-scale scraping. That belongs to a dedicated scraper with rate limits, robots.txt handling, and a real user agent policy — not this skill.
+- The site is behind authentication you do not own credentials for, or whose terms of service prohibit automation.
+- The site involves sensitive accounts (banking, healthcare, government) where automation risks lockout or compliance issues.
+
+## Before launching the browser
+
+- Confirm the URL and what state should be true after navigation.
+- Decide what evidence is needed: full-page screenshot, viewport screenshot, console log, network trace, HTML snapshot, extracted text.
+- Decide the viewport size that matters for the task (mobile vs desktop). Default to a desktop size unless the task is mobile-specific.
+- For local dev servers, confirm the server is running and the port is what you expect.
+
+## Driving the browser
+
+A typical verification session:
+
+1. **Launch with a real-looking user agent** when the target is the public internet; an unrealistic UA flags automation traffic.
+2. **Set a sane viewport** (e.g., 1366×768 desktop, 390×844 iPhone-ish).
+3. **Navigate and wait for the right signal.** Prefer waiting for a specific selector or network-idle over arbitrary sleeps.
+4. **Capture evidence immediately** after the wait condition succeeds, before any interaction perturbs the state.
+5. **Interact deliberately.** One click at a time, with a wait between actions; re-screenshot after each meaningful state change.
+6. **Read the console and network panels** for unexpected errors, 4xx/5xx responses, or slow requests.
+7. **Close the browser cleanly** when done. Long-running browser sessions leak memory and hold ports.
+
+## What evidence to record
+
+For a verification task, deliver:
+
+- A full-page or viewport screenshot of each meaningful state.
+- The console log, filtered to warnings/errors.
+- Any non-2xx network response with the URL, status, and a short response body excerpt.
+- A short narration: "Navigated to X, observed Y, clicked Z, observed W."
+
+For a UI bug repro, also record:
+
+- The exact reproduction steps the user can follow.
+- Viewport size and (where relevant) device pixel ratio.
+- Whether the bug reproduces on first load vs after interaction.
+
+## Login-gated pages
+
+- Prefer programmatic auth (API token, magic link) over UI login.
+- If UI login is the only path, the user must provide credentials explicitly for this run. Never reuse credentials outside the session.
+- Do not store credentials in the session log, screenshot, or returned output.
+
+## Performance and politeness
+
+- Throttle to one navigation per few seconds when touching shared infra.
+- Respect `robots.txt` for public sites you are inspecting at any volume.
+- Cancel navigations if a page exceeds a reasonable timeout (e.g., 30s); the page is broken or rate-limiting you.
+- Do not retry forever on failure. Retry once with a longer timeout, then escalate.
+
+## Common failure modes
+
+- **Selector not found.** Page changed, or you are waiting before render. Take a screenshot to see actual state; adjust the selector.
+- **Click does nothing.** The element is offscreen, covered by a modal, or in a shadow DOM. Scroll into view or pierce the shadow root.
+- **Headless detection.** Some sites detect headless Chrome and serve a different page. Use a non-headless mode or a fingerprint-realistic configuration only when authorized.
+- **Cross-origin iframe blocking.** Iframes you do not own cannot be inspected; the page must offer the data outside the iframe or the task is infeasible.
+
+## Anti-patterns
+
+- Long unsupervised browser sessions that drift from the original task.
+- Scraping behind authentication you do not own.
+- Captioning a screenshot with "looks good" without saying what state was loaded and what selectors confirmed it.
+- Treating a passing screenshot as proof of correctness across viewports you did not actually test.

+# Release Announcement
+
+Write the channel-appropriate announcement for a release without churn. Different surfaces need different shapes: a changelog entry is not a blog post is not a social card. The bar is: a reader of the chosen surface can decide in under 30 seconds whether this release affects them, and if so what to do.
+
+## When to use
+
+- A version, feature, or fix is shipping and needs writeup for at least one surface.
+- A previously private feature is going GA.
+- A breaking change needs broadcast before users hit it.
+
+## When not to use
+
+- An internal-only change with no user impact. Update internal docs; do not announce.
+- The release is incomplete (still in active development). Wait until it ships, even if marketing wants the post.
+
+## Determine the audience and channel first
+
+| Audience | Best channel | Tone |
+|---|---|---|
+| Existing power users | Changelog, in-app note | Terse, factual, links |
+| Engineering teams adopting your API | Release notes, dev blog | Examples, migration steps, version pins |
+| Prospective customers | Landing page, marketing blog | Story arc, problem → solution, social proof |
+| Broad audience | Social post, email newsletter | One-sentence pitch, link to depth |
+| Internal team | Slack/Discord post | What changed, who to ping if it breaks |
+
+Pick the audience for *this* writeup. One release often needs several writeups; do not blend them.
+
+## Universal structure
+
+Whatever the channel, lead with:
+
+1. **What changed.** One sentence in the user's vocabulary.
+2. **Who it affects.** Which user role / use case.
+3. **What to do.** Migrate now / opt-in / no action needed.
+
+Everything else is depth that supports those three.
+
+## Channel templates
+
+### Changelog entry (terse)
+
+```md
+## v1.42.0 — 2026-05-26
+
+### Added
+- <feature> — <one-line user benefit>. ([#1234](link))

+
+### Breaking
+- <change>. **Migration:** <one-line> or <link to guide>.
+```
+
+### Release notes (for adopters)
+
+Same as changelog, plus:
+
+- Migration guide section with before/after code.
+- Compatibility table (versions, runtimes, OS).
+- Known issues and workarounds.
+- Acknowledgements (contributors, reporters of fixed bugs).
+
+### Dev blog post (300–800 words)
+
+- **Hook (1 paragraph):** the problem the release solves, in a real-world scenario.
+- **What's new (3–5 bullets with sub-paragraphs):** features, with one code or screenshot example each.
+- **Upgrade (1 paragraph):** how to upgrade, what to check.
+- **What's next:** one sentence about the next direction. Avoid promises.
+
+### In-app note
+
+- 1 sentence.
+- 1 link.
+- Dismiss after seen.
+
+### Social post
+
+- 1 sentence pitch.
+- 1 link.
+- 1 image or short clip.
+- No threadbait. If it needs a thread, write a blog post instead.
+
+## Writing rules
+
+- Lead with the user, not the team. `You can now export to CSV` beats `We've added CSV export`.
+- Numbers beat adjectives. `60% faster cold start` beats `much faster`. Cite the methodology.
+- Show, don't just tell. One code snippet, one screenshot — more is noise.
+- Date the post. Undated release content rots fastest.
+- Link the migration path explicitly. Do not bury it.
+- Mark breaking changes with `**Breaking:**` prefix. Repeat in the email/social channel.
+
+## Avoid
+
+- "We are excited to announce" filler.
+- Lists of changes that mix user-visible and internal items.
+- Marketing claims without a way to verify.
+- Promised dates for unshipped work.
+- Pre-announcing something the team has not yet committed to ship.
+
+## Post-publish checklist
+
+- Changelog is in source control alongside the release.
+- Blog post date matches actual ship date.
+- All links work (release tag, PRs, docs sections).
+- Breaking changes are also in the upgrade guide, not only the post.
+- Internal team is notified before the public post goes live, not after.

+# Product Design Critique
+
+A structured critique pass for a screen, flow, or component. The output is a prioritized list of changes a designer or engineer can act on — not adjectives. Critique is not redesign; recommend, do not rebuild.
+
+## When to use
+
+- A designer or engineer asks for feedback on a screen, mock, or live UI.
+- A feature is shipping and someone wants a final UX read.
+- A flow is suspected of causing user drop-off and you want a pre-research read before instrumentation.
+
+## When not to use
+
+- The user wants a redesign. That is a design project, not a critique.
+- The work is so early that no concrete artifact exists. Sketch with them instead of critiquing air.
+- You have no context on the user job. Ask for it first; design critique without user context devolves into taste.
+
+## Pre-critique context
+
+Before opening a screen, get:
+
+- **Who is the user.** Specific role and competence, not "users".
+- **What job they are doing on this screen.** One sentence.
+- **What success looks like.** What the user can do after this screen that they could not before.
+- **Where this screen sits in the larger flow.** What precedes and follows.
+
+If any of these is missing, ask. Critique without these is opinion.
+
+## The pass (in order)
+
+1. **Clarity of the user job.**
+   - Within 3 seconds of opening, is it obvious what this screen is for?
+   - Does the primary action match the user's actual job, or a designer's preferred path?
+
+2. **Visual hierarchy.**
+   - The most important thing on the screen should be the most prominent (size, weight, position, color).
+   - Secondary actions should look secondary. Tertiary should be findable but not loud.
+   - Headings should chunk content into the right groups for the task.
+
+3. **Affordance and signifiers.**
+   - Clickable things look clickable.
+   - Disabled things look disabled and explain why on hover/focus.
+   - Drag, scroll, or swipe interactions are discoverable, not hidden.
+
+4. **States.**
+   - Empty state (no data) is designed, not a blank rectangle.
+   - Loading state communicates progress, not just spins.
+   - Error states say what went wrong and what to do next, in the user's words.
+   - Success state confirms without celebrating banal actions.
+
+5. **Inputs and forms.**
+   - Labels visible, not just placeholders.
+   - Validation runs at the right time (on blur, not on every keystroke unless the user is in a known-format field).
+   - Required fields marked.
+   - Field order matches the user's mental order, not the database order.
+
+6. **Accessibility.**
+   - Sufficient color contrast (WCAG AA at minimum; AAA where reasonable).
+   - Focus order is logical for keyboard navigation.
+   - Interactive elements are reachable without a mouse.
+   - Critical information is not color-only (icons, text, position back it up).
+   - Touch targets at least 44×44 px on mobile.
+
+7. **Consistency.**
+   - Tokens, components, and patterns match the rest of the product.
+   - "Borrowed" patterns from other products are intentional, not accidental drift.
+
+8. **Copy.**
+   - Buttons are verbs that name the outcome ("Save changes" beats "Submit").
+   - Microcopy explains, does not decorate.
+   - Tone matches the product voice.
+
+9. **Edge cases.**
+   - Long content (long names, many items, RTL languages).
+   - Tiny content (one item, zero items).
+   - Slow network and offline behavior.
+   - Permissions denied.
+
+## Output format
+
+Group findings by severity, then by category. Each finding is one issue and one suggested fix.
+
+```md
+## Design critique: <screen name>
+
+### Must-fix (blocks ship)
+- **<category>:** <one-line issue>. **Try:** <one-line suggestion>.
+
+### Should-fix (before broader rollout)
+- **<category>:** <one-line issue>. **Try:** <one-line suggestion>.
+
+### Nice-to-fix (when there's room)
+- **<category>:** <one-line issue>. **Try:** <one-line suggestion>.
+
+### Strengths to keep
+- <one-line thing the design got right>
+```
+
+Always include the "strengths to keep" section. It is not flattery — it is signal to the designer about what not to change in the next round.
+
+## Anti-patterns
+
+- "I would do it differently" without saying what or why. That is preference, not critique.
+- Long critiques that bury must-fix items under nice-to-haves.
+- Suggesting net-new features under the guise of a critique.
+- Ignoring user context and grading on taste.
+- Treating a critique as approval. State approval explicitly if asked; otherwise critique is feedback, not sign-off.

+- Company skill library: install, inspect, update, audit, reset, and read company skills for the whole company.
 - Agent skill assignment: add or remove company skills on an existing agent.
 - Hire/create composition: pass `desiredSkills` when creating or hiring an agent so the same assignment model applies immediately.
 
 The canonical model is:
 
-1. install the skill into the company
-2. assign the company skill to the agent
+1. add the skill to the company library — either from the app catalog (`skills install`), an external source (`skills import`), or a managed local skill (`skills create`/`skills scan-projects`)
+2. attach the company skill to the agent (`skills agent sync`)
 3. optionally do step 2 during hire/create with `desiredSkills`
 
+Catalog install ≠ agent attach. Installing a catalog skill only adds the row to
+`company_skills`. The agent will not use it until you sync the agent's desired
+set.

+
 ## Install A Skill Into The Company
 
+Two paths cover the common cases:
+
+1. **App-shipped catalog** (preferred when the right skill exists in the
+   bundled/optional catalog) — browse it first, then install with the catalog
+   install endpoint. No external network fetch happens.
+2. **External source** (skills.sh, GitHub, local path, or URL) — use the
+   import endpoint below.
+
+### App-shipped catalog
+
+Browse, inspect, and install catalog skills before reaching for an external
+source. Bundled skills are the curated defaults for any company; optional
+skills are role- or domain-specific.
+
+```sh
+curl -sS "$PAPERCLIP_API_URL/api/skills/catalog?kind=bundled" \
+  -H "Authorization: Bearer $PAPERCLIP_API_KEY"
+
+curl -sS "$PAPERCLIP_API_URL/api/skills/catalog/ref?ref=github-pr-workflow" \
+  -H "Authorization: Bearer $PAPERCLIP_API_KEY"
+
+curl -sS -X POST "$PAPERCLIP_API_URL/api/companies/$PAPERCLIP_COMPANY_ID/skills/install-catalog" \
+  -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "catalogSkillId": "paperclipai:bundled:software-development:github-pr-workflow"
+  }'
+```
+
+The install response records provenance (`catalogId`, `catalogKey`,
+`packageVersion`, `originHash`) on the company skill so update/audit/reset
+flows know the pinned origin. `force: true` may replace a same-key
+catalog-managed skill but never bypasses hard-stop audit findings.
