## Thinking Path > - Paperclip agents use task context to complete assigned work. > - Sandboxed agents reach the controller through a bounded callback bridge. > - The bridge rejects several documented context routes before controller authorization runs. > - An authorized agent cannot read a task screenshot or referenced skill file, or inspect a missed monitor wake. > - This pull request admits only the exact context routes and supported methods. > - The controller continues to enforce company, resource, task and monitor authority. ## Linked Issues or Issue Description **What happened?** Both callback transports return `Route not allowed` for task asset content, company skill detail and files, wake diagnostics, and the monitor check-now action. These operations already exist in the controller. **Expected behavior** A sandboxed agent can use these documented operations when the controller authorizes its request. Other methods, deeper paths, skill mutations, and recovery resolution remain restricted. **Steps to reproduce** Use a sandbox callback to read an asset URL from a task description, read a company skill's referenced file, or inspect a task's wake diagnostics. The baseline bridge rejects each request. The new regression matrix runs all five operations against both transport allowlists. Related: #16772 documents refused callback routes. This PR fixes the context routes listed above; it does not add company-wide activity or labels access. ## What Changed - Admit asset content, skill detail/files, and wake diagnostic reads. - Admit the existing monitor check-now action with controller authorization. - Add a focused allow/deny matrix for both transports. - Update the operational API reference and access maps. ## Verification - With the pre-fix bridge rules, all 10 allowed-request cases fail with `Route not allowed` across the two transports; all 24 deny controls still pass. - With the fix restored, all 34 route cases pass. The matrix plus existing callback suite passes 119 tests across two files. - Local `pnpm -r typecheck` and `pnpm build` pass. - The access-map checker, capability contract generation check, and capability inventory check pass. - Full repository CI passes on `97f9f06b2c`: typecheck/release registry, all test shards, build, Docker context, canary dry run, and aggregate verify. - The duplicate local full-suite run was stopped after 24 minutes once full CI passed; it is not claimed as a completed local pass. - Greptile is 5/5 on the current head with no inline findings. Independent source review checked asset, skill, wake-diagnostic, and monitor controller authorization and found no actionable issues. - The secondary Paperclip automated review is neutral/incomplete. Independent review covered its missing controller checks; the real Vitest cases and full CI provide execution evidence. ## Risks This widens transport admission for five existing operations. It does not change controller authorization. Asset reads still check company/task visibility; skill reads keep source policy; monitor checks keep ownership and management permission. No schema or UI change is required. ## Model Used OpenAI Codex, GPT-6 family, with tool use and code execution. The session does not expose the exact serving model ID or context window. The work used failing-before and passing-after regression tests. ## 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: 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.
Sandbox bridge deadlines
Command-managed bridge control operations (queue reads, input delivery, setup, and cleanup) have a host-enforced deadline of at most 30 seconds per shell command. A shorter configured timeout still applies. These operations cannot inherit the agent run's hours-long lifetime or wait forever on a provider that ignores its timeout. Long-lived agent session commands keep their own limits.
A control timeout reports a transport failure. It does not prove that the remote command stopped and does not replay an uncertain write. The process session closes failed input delivery and uses its existing shutdown path; normal execution settlement must still verify termination.
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.
