## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The task chat shows each tool call an agent makes as a short activity row. > - Real Claude runs showed Bash rows named "Terminal" with no command and Write rows stuck at "Preparing file…". No row showed an exit code or a duration, and a tool refused by policy looked like any other failure. > - Codex already reported exit codes, durations and parsed command actions, but the UI dropped them, and every Codex read looked like a shell command. > - This pull request gives both harnesses one row grammar: a verb icon, the real subject, an exit chip and a duration. > - The benefit is that a reviewer can see what ran and how it went without opening each row. ## Linked Issues or Issue Description Refs #19259 (this branch includes its `_meta` passthrough commit; merge #19259 first or together). **Problem or motivation** Claude tool rows hide what ran: the runner keeps the first ACP title ("Terminal", "Preparing file…") and drops the refined one. `exitCode` and `durationMs` are null on every Claude tool event. The UI ignores `tool.execution.progressed`, `exitCode` and `durationMs` for every harness. **Proposed solution** Read real tool facts in the runner (Claude `_meta.claudeCode`, raw input and result text; Codex `commandActions`), carry them in the canonical tool event, and render one row grammar in the task chat. **Alternatives considered** Enable Claude's `terminal_output` client capability to get `terminal_exit`. That changes how command output arrives, and Claude's own exit code is derived from the error flag anyway, so this PR reads the error flag and the "Exit code N" text instead. ## What Changed - **Runner (TS):** `createAcpxToolEventNormalizer` keeps the latest concrete title instead of the first placeholder. It merges tool facts across the lifecycle and measures the duration. New `acpxToolDetailFromRuntimeEvent` reads the native tool name, the command or pattern, the description, the exit code and a "Permission denied" reason. Exit 0 is inferred only for Claude `Bash`, where a non-zero exit is always a failed result. - **ACPX sidecar:** reads the facts before `rawInput` is dropped and sends a bounded `toolDetail`. A file path argument becomes an attested workspace-relative location. - **runner-core (Rust):** validates `toolDetail`. `normalize_acpx_tool_call` uses the native name, exit code, duration, subject, description and blocked reason. Codex `commandExecution` gets its operation, a single-file target and a subject from `commandActions`. The shell wrapper is removed, and a single search reads as `"TODO" in src`. - **Protocol:** `toolExecution` gains the optional fields `subject`, `description` and `blockedReason`. Generated validators and the manifest are regenerated. - **UI:** - `nativeRunEventsToTranscript` handles `tool.execution.progressed` and passes a canonical `detail` on `tool_call` entries. - The task-chat row shows `$ command`, a path or a pattern, a red `exit N` chip (exit 0 only for commands) and a duration (0 is hidden). - Three or more consecutive reads fold into "Read N files a, b, c +1". - A refused tool shows "Blocked" with its reason. - **Storybook:** `Tasks/Tool rows` compares the data recorded today with the new runner data for Claude and Codex. ## Verification - `cd packages/paperclip-runner && npx vitest run src/provider-events.test.ts src/cli src/drivers/acpx` (1,957 pass) - `cd packages/paperclip-runner/runner && cargo test -p paperclip-runner-core --lib provider_events` - `cd ui && npx vitest run src/components/transcript src/components/task-chat` (973 pass) - `pnpm check:token-gates`, `pnpm --filter paperclip-runner build` (includes the protocol coverage and replay-golden checks) - Live runs on a local instance with real harnesses: - Codex (gpt-5.6-sol): the rows read `$ node --test` with `exit 1` and then `exit 0`, plus real durations. A three-file `sed` shows as one command and does not claim a single file. - Claude (claude-sonnet-5-5 through ACPX): the rows show `Bash` and `Edit` instead of "Terminal" and "Preparing file…". Commands show their real text, `exit 0` and durations, and edits show `Edited temp.js`. - Not seen live: a real Claude `Write`, a folded read run and a Claude policy denial. Unit and Rust tests cover them. ## Risks - The tool-execution schema gains only optional fields, so older events stay valid. Older runs keep rendering with what they recorded. - Commands now cross the sidecar boundary as `subject` (bounded to 4,000 characters). Codex already recorded commands as the tool name, and server redaction still applies. - The tool lifecycle now keeps the latest concrete title. A provider that retitles a call to something less useful would show the newer title. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use, code execution and browser automation. ## 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 - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [ ] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
@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.
