This document indexes every part of the Paperclip codebase that touches the [Agent Companies Specification](docs/companies/companies-spec.md) (`agentcompanies/v1-draft`).
Use it when you need to:
1.**Update the spec** — know which implementation code must change in lockstep.
2.**Change code that involves the spec** — find all related files quickly.
3.**Keep things aligned** — audit whether implementation matches the spec.

## 1. Specification & Design Documents
| File | Role |
|---|---|
| `docs/companies/companies-spec.md` | **Normative spec** — defines the markdown-first package format (COMPANY.md, TEAM.md, AGENTS.md, PROJECT.md, TASK.md, SKILL.md), reserved files, frontmatter schemas, and vendor extension conventions (`.paperclip.yaml`). |
| `doc/plans/2026-03-13-company-import-export-v2.md` | Implementation plan for the markdown-first package model cutover — phases, API changes, UI plan, and rollout strategy. |
| `doc/SPEC-implementation.md` | V1 implementation contract; references the portability system and `.paperclip.yaml` sidecar format. |
| `docs/specs/cliphub-plan.md` | Earlier blueprint bundle plan; partially superseded by the markdown-first spec (noted in the v2 plan). |
| `doc/plans/2026-02-16-module-system.md` | Module system plan; JSON-only company template sections superseded by the markdown-first model. |
| `packages/shared/src/validators/company-portability.ts` | Zod schemas for all portability request/response shapes — used by both server routes and CLI. |
| `server/src/services/routines.ts` | Paperclip routine runtime service. Portability now exports routines as recurring `TASK.md` entries and imports recurring tasks back through this service. |
Route registration lives in `server/src/app.ts` via `companyRoutes(db, storage)`.
## 5. Server — Tests
| File | Coverage |
|---|---|
| `server/src/__tests__/company-portability.test.ts` | Unit tests for the portability service (export, import, preview, manifest shape, `agentcompanies/v1` version). |
| `server/src/__tests__/company-portability-routes.test.ts` | Integration tests for the portability HTTP endpoints. |
| `cli/src/commands/client/company.ts` | `company export` — exports a company package to disk (flags: `--out`, `--include`, `--projects`, `--issues`, `--projectIssues`).<br>`company import <fromPathOrUrl>` — imports a company package from a file or folder (flags: positional source path/URL or GitHub shorthand, `--include`, `--target`, `--companyId`, `--newCompanyName`, `--agents`, `--collision`, `--ref`, `--dryRun`).<br>Reads/writes portable file entries and handles `.paperclip.yaml` filtering. |
| `ui/src/pages/CompanyExport.tsx` | Export UI: preview, manifest display, file tree visualization, ZIP archive creation and download. Filters `.paperclip.yaml` based on selection. Shows manifest and README in editor. |
| `ui/src/components/PackageFileTree.tsx` | Reusable file tree component for both import and export. Builds tree from `CompanyPortabilityFileEntry` items, parses frontmatter, shows action indicators (create/update/skip), and maps frontmatter field labels. |
| `ui/src/lib/zip.ts` | ZIP archive creation (`createZipArchive`) and reading (`readZipArchive`) — implements ZIP format from scratch for company packages. CRC32, DOS date/time encoding. |
| `ui/src/lib/zip.test.ts` | Tests for ZIP utilities; exercises round-trip with portability file entries and `.paperclip.yaml` content. |
## 10. UI — API Client
| File | Functions |
|---|---|
| `ui/src/api/companies.ts` | `companiesApi.exportBundle`, `companiesApi.exportPreview`, `companiesApi.exportPackage`, `companiesApi.importPreview`, `companiesApi.importBundle` — typed fetch wrappers for the portability endpoints. |
## 11. Skills & Agent Instructions
| File | Relevance |
|---|---|
| `skills/paperclip/references/company-skills.md` | Reference doc for company skill library workflow — install, inspect, update, assign. Skill packages are a subset of the agent companies spec. |
| `server/src/services/company-skills.ts` | Company skill management service — handles SKILL.md-based imports and company-level skill library. |
| `server/src/services/agent-instructions.ts` | Agent instructions service — resolves AGENTS.md paths for agent instruction loading. |
