## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - There are many adapter types, one per agent-runtime product (Claude,
Codex, OpenCode, Cursor local CLI, etc.)
> - Cursor shipped a public TypeScript SDK on 2026-04-29 that exposes
Cursor's full hosted-agent platform (cloud VMs, harness, MCP, skills,
hooks)
> - Paperclip had no first-class adapter for this — agents that wanted
to use Cursor's managed cloud runtime had to fall back to the local CLI
adapter, which loses the cloud session, streaming, and durable run model
> - This PR adds a new `cursor_cloud` adapter built directly on
`@cursor/sdk`, with Paperclip's heartbeat mapped to Cursor's
durable-agent + per-run model
> - The benefit is that any Paperclip agent can now drive a Cursor cloud
agent across heartbeats with native session reuse, streaming, and
cancellation, while Paperclip remains the source of truth for issue/task
state
## What Changed
- New built-in adapter package `packages/adapters/cursor-cloud` (15
files, ~1.7k LOC) backed by `@cursor/sdk` ^1.0.12
- `src/server/execute.ts` — SDK-first lifecycle: `Agent.create` /
`Agent.resume` / `Agent.getRun` / `agent.send` / `run.stream` /
`run.wait`, with session reuse keyed on the (runtime env type, env name,
repo set) tuple
- `src/server/session.ts` — codec for `cursorAgentId` + `latestRunId` +
repo metadata, persisted in `runtime.sessionParams`
- `src/server/test.ts` — environment probe via `Cursor.me()` and
optional model validation via `Cursor.models.list()`
- `src/ui/parse-stdout.ts` + `src/cli/format-event.ts` — normalize
Cursor SDK message types (`status`, `thinking`, `assistant`, `user`,
`tool_call`, `tool_result`, `result`) into Paperclip transcript events
for the UI and CLI
- Registrations: `packages/shared/src/constants.ts`,
`packages/adapter-utils/src/session-compaction.ts`,
`server/src/adapters/{registry,builtin-adapter-types}.ts`,
`ui/src/adapters/{registry,adapter-display-registry}.ts` +
`ui/src/adapters/cursor-cloud/index.ts`, `cli/src/adapters/registry.ts`,
plus workspace deps in `cli`/`server`/`ui` `package.json`
- `ui/src/components/AgentConfigForm.tsx` — hide local-Cursor
`mode`/thinking-effort field for `cursor_cloud` (different config
surface)
- 11 vitest tests covering execute paths (fresh create, matching-resume,
active-run reattach, non-finished result), session codec round-trip,
transcript parsing, and config building
## Verification
Reviewer steps:
```bash
pnpm install
pnpm --filter @paperclipai/adapter-cursor-cloud typecheck # → clean
pnpm vitest run packages/adapters/cursor-cloud # → 11/11 passing
```
End-to-end check against a real Cursor cloud agent (requires
`CURSOR_API_KEY` and Cursor GitHub-app install on the target repo):
1. Create a `cursor_cloud` agent in Paperclip with `repoUrl` set to the
test repo, `repoStartingRef: main`, and `env.CURSOR_API_KEY` set
2. Trigger a heartbeat → adapter calls `Agent.create({ cloud: { env: {
type: "cloud" }, repos: [...] } })`, streams events, terminates on
`finished`
3. Trigger a second heartbeat → adapter calls `Agent.resume` or
`agent.send` follow-up depending on prior-run state, reusing
`cursorAgentId`
4. The Paperclip UI/CLI transcript reflects Cursor `status` / `thinking`
/ `assistant` events as they stream
5. Cancellation from Paperclip maps to `run.cancel()` or Cloud API v1
`cancelRun` for cross-heartbeat cancellation
A direct-SDK smoke run against a real repo (devinfoley/my_test_project @
main) confirmed: `Cursor.me()` ok → `Agent.create` → `agent.send` →
`run.stream()` (30 events) → terminal status `finished` in ~11s.
## Risks
- **New adapter, additive only.** No existing adapter or registry is
replaced; current `cursor` local-CLI adapter is untouched. Default
behavior of any existing agent is unchanged.
- **External dependency on `@cursor/sdk`.** Cursor's SDK is v1.0.x and
may evolve. Mocked unit tests cover the public surface used here; if the
SDK breaks compatibility we update the adapter independently.
- **Cost/budget.** `cursor_cloud` runs on Cursor's billed cloud VMs;
operators must understand they are spending money outside Paperclip's
budget controls when they enable this adapter. Same shape as other
API-billed adapters.
- **No webhook support in V1.** The SDK already provides
stream/wait/cancel/reattach, so V1 does not require a public callback
URL. If a future use case needs out-of-band wakes, we add a Cloud API v1
webhook bridge as a separate change. This is called out in the issue
plan document.
- **Lockfile.** Per repo policy, `pnpm-lock.yaml` is intentionally not
in this PR — CI's lockfile workflow will update it on merge given the
manifest changes.

## Thinking Path
> - Paperclip orchestrates AI-agent companies through a control plane
that can start, supervise, and recover agent runs.
> - Local adapters are the bridge between Paperclip issues and concrete
agent runtimes such as Claude, Codex, and other ACP-compatible tools.
> - The roadmap calls out broader “bring your own agent” and claw-style
agent support, and ACPX gives Paperclip one path to normalize multiple
ACP agents behind a single adapter.
> - The branch needed to become one reviewable PR against current
`paperclipai/paperclip:master`, without carrying stale base conflicts or
generated lockfile churn.
> - This pull request adds an experimental built-in `acpx_local`
adapter, integrates it through the server/CLI/UI adapter surfaces, and
adds regression coverage for runtime execution, skill sync, stream
parsing, diagnostics, and log redaction.
> - The benefit is that Paperclip can run Claude/Codex/custom ACP agents
through ACPX while keeping operator configuration, skills, logging, and
transcript rendering inside the existing adapter model.
## What Changed
- Added `@paperclipai/adapter-acpx-local` with server execution, config
schema, ACPX session handling, CLI formatting, UI config helpers, and
stdout parsing.
- Registered `acpx_local` across CLI, server, shared constants, UI
adapter metadata, adapter capabilities, and agent creation/editing
surfaces.
- Added ACPX runtime execution support with persistent sessions,
local-agent JWT environment handling, skill snapshots, runtime skill
materialization, and isolation/security regressions.
- Added ACPX adapter diagnostics and marked the adapter experimental in
the UI.
- Added command/env secret redaction for resolved command metadata in
adapter-utils, server event storage, and the Agent Detail invocation UI.
- Added Storybook coverage for ACPX config, transcript rendering, and
skill states, plus PR screenshots under `docs/pr-screenshots/pap-2944/`.
- Rebased the branch onto current `public-gh/master`; `pnpm-lock.yaml`
is intentionally not included and there are no migration/schema changes.

## Risks
- Medium risk: this introduces a new built-in adapter package and
touches runtime execution, adapter registration, agent config, skills,
and transcript rendering.
- ACPX and ACP agent behavior can vary by installed tool versions; the
adapter is marked experimental to set operator expectations.
- `pnpm-lock.yaml` is excluded per repository PR policy, so dependency
lock refresh must be handled by the repo’s automation or maintainers.
- No database migration risk: no schema or migration files changed.

Co-authored-by: Paperclip <noreply@paperclip.ing>
## Thinking Path
> - Paperclip is a control plane for AI-agent companies.
> - External adapters can provide UI parser code that the board loads
dynamically for run transcript rendering.
> - Running adapter-provided parser code directly in the board page
gives that parser access to same-origin browser state.
> - This PR narrows that surface by evaluating dynamically loaded
external adapter UI parser code in a dedicated browser Web Worker with a
constrained postMessage protocol.
> - The worker here is a frontend isolation boundary for adapter UI
parser JavaScript; it is not Paperclip's server plugin-worker system and
it is not a server-side job runner.
## What Changed
- Runs dynamically loaded external adapter UI parsers inside a dedicated
Web Worker instead of importing/evaluating them directly in the board
page.
- Adds a narrow postMessage protocol for parser initialization and line
parsing.
- Caches completed async parse results and notifies the adapter registry
so transcript recomputation can synchronously drain the final parsed
line.
- Disables common worker network, persistence, child worker, Blob/object
URL, and WebRTC escape APIs inside the parser worker bootstrap.
- Handles worker error messages after initialization and drains pending
callbacks on worker termination or mid-session worker error.
- Adds focused regression coverage for the parser worker lockdown and
unused protocol removal.
## Verification
- `pnpm exec vitest run --config ui/vitest.config.ts
ui/src/adapters/sandboxed-parser-worker.test.ts`
- `pnpm exec tsc --noEmit --target es2021 --moduleResolution bundler
--module esnext --jsx react-jsx --lib dom,es2021 --skipLibCheck
ui/src/adapters/dynamic-loader.ts
ui/src/adapters/sandboxed-parser-worker.ts
ui/src/adapters/sandboxed-parser-worker.test.ts`
- `pnpm --filter @paperclipai/ui typecheck` was attempted; it reached
existing unrelated failures in HeartbeatRun test/storybook fixtures and
missing Storybook type resolution, with no adapter-module errors
surfaced.
- PR #4225 checks on current head `34c9da00`: `policy`, `e2e`, `verify`,
`security/snyk`, and `Greptile Review` are all `SUCCESS`.
- Greptile Review on current head `34c9da00` reached 5/5.
## Risks
- Medium risk: parser execution is now asynchronous through a worker
while the existing parser interface is synchronous, so transcript
updates should be watched with external adapters.
- Some adapter parser bundles may rely on direct ESM `export` syntax or
browser APIs that are no longer available inside the worker lockdown.
- The worker lockdown is a hardening layer around external parser code,
not a complete browser security sandbox for arbitrary untrusted
applications.

Builtin adapter types (hermes_local, openclaw_gateway, etc.) could not
be overridden by external adapters on the UI side. The registry always
returned the built-in parser, ignoring the external ui-parser.js shipped
by packages like hermes-paperclip-adapter.
Changes:
- registry.ts: full override lifecycle with generation guard for stale loads
- disabled-overrides-store.ts: client-side override pause state with
useSyncExternalStore reactivity (persisted to localStorage)
- use-disabled-adapters.ts: subscribe to override store changes
- AdapterManager.tsx: separate controls for override pause (client-side)
vs menu visibility (server-side), virtual builtin rows with badges
- adapters.ts: allow reload/reinstall of builtin types when overridden
- Fix external adapters (hermes, droid) not auto-selected when
navigating with ?adapterType= param — was using a stale
module-level Set built before async adapter registration
- Move SchemaConfigFields to render after thinking effort (same
visual area as Claude's chrome toggle) instead of bottom of
config section
- Extract SelectField into its own component to fix React hooks
order violation when schema fields change between renders
- Add onAdapterChange() subscription in registry.ts so
registerUIAdapter() notifies components when dynamic parsers
load, fixing stale parser for old runs
- Add parserTick to both RunTranscriptView and
useLiveRunTranscripts to force recomputation on parser change
Re-align phase1 with upstream: hermes_local ships via hermes-paperclip-adapter on the server and UI (hermes-local module). Fixes ERR_PNPM_OUTDATED_LOCKFILE from server/package.json missing a dep still present in the lockfile.
Add shared BUILTIN_ADAPTER_TYPES and skip external plugin registration when it would override a built-in type. Docs list Hermes as built-in; Droid remains the primary external example.
Made-with: Cursor
- Plugin loader: install/reload/remove/reinstall external adapters
from npm packages or local directories
- Plugin store persisted at ~/.paperclip/adapter-plugins.json
- Self-healing UI parser resolution with version caching
- UI: Adapter Manager page, dynamic loader, display registry
with humanized names for unknown adapter types
- Dev watch: exclude adapter-plugins dir from tsx watcher
to prevent mid-request server restarts during reinstall
- All consumer fallbacks use getAdapterLabel() for consistent display
- AdapterTypeDropdown uses controlled open state for proper close behavior
- Remove hermes-local from built-in UI (externalized to plugin)
- Add docs for external adapters and UI parser contract
New adapter type for invoking OpenClaw agents via the gateway protocol.
Registers in server, CLI, and UI adapter registries. Adds onboarding
wizard support with gateway URL field and e2e smoke test script.

Introduce openclaw adapter package with server execution, CLI stream
formatting, and UI config fields. Register the adapter across CLI,
server, and UI registries. Add adapter label in all relevant pages.

Refactor monolithic heartbeat service, AgentConfigForm, and CLI
heartbeat-run into a proper adapter registry pattern. Each adapter
type (process, claude-local, codex-local, http) gets its own module
with server-side execution logic, CLI invocation, and UI config form.
Significantly reduces file sizes and enables adding new adapters
without touching core code.
