## Thinking Path > - Paperclip is a control plane that orchestrates AI agents and adapter execution for human operators. > - Agents run across local and remote execution contexts, and reliability in remote sessions depends on consistent adapter bootstrapping. > - The ACP path must prepare per-adapter runtime homes so managed credentials and config are available in sandboxed runner environments. > - Before this change, the new remote ACP lane did not yet consistently stage managed-home paths for all affected adapters or restore Codex auth state on teardown. > - We added a shared per-adapter seam in the ACP engine, then wired Codex, Claude, and Gemini remote lanes to seed managed homes and remap to in-sandbox locations. > - Codex additionally reuses the existing atomic auth restore flow to copy auth back on teardown, matching CLI behavior. > - This improves remote runner parity with existing CLI behavior and avoids credential drift in shared-code-path executions. ## Linked Issues or Issue Description - This change continues the ACP remote managed-home work by completing per-adapter remote bootstrapping and Codex auth restore behavior for the remote ACP lane. - It specifically covers: `acpx-engine`, `codex-local`, `claude-local`, and `gemini-local`. - Related prior work in this repo: PR #10070. ## What Changed - Add a per-adapter remote managed-home seam (`prepareRemoteManagedHome`) in `acpx-engine` and thread it through ACP execution options. - Implement Codex ACP preparation to: - stage `CODEX_HOME` (auth/config/skills) into a sandboxed remote home, - repoint `CODEX_HOME` to the in-sandbox path, - and wire teardown copy-back through the existing managed-auth restore path. - Implement Claude ACP preparation to seed a sanitized `config-seed` into `CLAUDE_CONFIG_DIR` and remap that directory to the sandbox root. - Implement Gemini ACP preparation to seed `~/.gemini/skills`, set `HOME` to managed runtime root, and preselect API-key auth in `settings.json`. - Keep local and runner-less ACP→CLI behavior unchanged by only invoking the remote managed-home seam when running in remote ACP mode. - Preserve existing authorization and activity boundaries in the shared engine and adapter layers. ## Verification - `git log --oneline origin/master..origin/feat/acp-remote-managed-home-seed` confirms only the expected 4 commits. - `tsc --noEmit` is clean in `adapter-utils`, `codex-local`, `claude-local`, and `gemini-local`. - Vitest selection used during validation passed (120 tests across the ACP-related suites). ## Risks - If remote sandbox teardown occurs after token rotation but before restore timing, Codex credentials can become stale and require re-auth on next startup. - Partial provisioning of managed-home assets would cause adapter bootstrap failures in runner-backed ACP sessions. - This change is scoped to execution-path behavior; it should not affect CLI behavior. ## Model Used None — human-authored. ## 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 searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Harold Kim <harold@paperclip.ing> Co-authored-by: Paperclip <noreply@paperclip.ing>
@paperclipai/adapter-utils
Shared utilities for Paperclip adapters: process spawning, environment injection, sandbox/SSH transport, workspace sync, and the round-trip helpers that move code between the local execution-workspace cwd and wherever the agent actually runs.
For the adapter-author guide see
docs/adapters/creating-an-adapter.md
and the in-repo notes at packages/adapters/AUTHORING.md.
No-remote-git contract
The local execution-workspace cwd is the only persistence boundary across runs. No adapter may depend on a git remote for cross-run state.
Adapters that run the agent on a different host should use the SSH round-trip
helpers in src/ssh.ts:
prepareWorkspaceForSshExecution({ spec, localDir, remoteDir })— bundles the local cwd (tracked files, dirty edits, untracked additions, and the git history needed to reconstruct it) toremoteDirbefore the run starts. Runs with nogit remoteconfigured.restoreWorkspaceFromSshExecution({ spec, localDir, remoteDir, ... })— syncs the remote cwd back intolocalDirafter the run, including any new commits the agent created. Also runs with nogit remoteconfigured.
prepareRemoteManagedRuntime in
src/remote-managed-runtime.ts wraps both
calls for adapters that want a per-run remote workspace and an automatic
restoreWorkspace() finally hook.
The invariant is pinned by the no-remote-git contract case in
src/ssh-fixture.test.ts, which asserts that a
remote-only commit propagates to the local worktree through the
prepare → restore round-trip with no git remote configured at any point. Do
not regress that test.
