## Thinking Path > - Paperclip is the open source control plane teams use to manage AI agents and their work > - The Codex local adapter supervises CLI child processes and terminates genuinely silent runs > - The existing inactivity timer only recognized parsed JSONL stdout events as activity > - Long verification commands can emit ordinary stdout or stderr while producing no JSONL, so healthy children could be killed > - This pull request makes the watchdog observe raw child-process output before filtering or parsing > - The benefit is that long typecheck, build, and test phases survive while truly silent children remain bounded ## Linked Issues or Issue Description - **Bug:** The Codex output-inactivity watchdog could terminate healthy runs during long verification phases because non-JSON stdout and stderr did not reset its timer. - **Expected:** Any bytes emitted by the child process count as output activity; only a child with no stdout or stderr for the configured interval is terminated. - **Reproduction:** Configure a short `outputInactivityTimeoutMs`, run a Codex child that periodically emits plain-text verification progress without JSONL events, and observe the old monitor firing despite continued output. - **Deployment mode:** Local `codex_local` adapter execution. - Related implementation: #5017 - Related recovery behavior: #8680 ## What Changed - Reset the Codex inactivity monitor on every non-empty stdout or stderr chunk before stderr noise filtering. - Track raw output chunk and byte counts in monitor diagnostics while retaining parsed JSONL event counts. - Add regression coverage for more than 21 simulated minutes of non-JSON verification output and retain silent-child termination coverage. - Document that `outputInactivityTimeoutMs` observes raw child output and that `null` still disables the monitor. ## Verification - `/srv/paperclip/home/paperclipai/paperclip/node_modules/.bin/vitest run packages/adapters/codex-local/src/server/output-inactivity-monitor.test.ts packages/adapters/codex-local/src/server/output-inactivity-monitor.integration.test.ts` - `/srv/paperclip/home/paperclipai/paperclip/node_modules/.bin/tsc -p packages/adapters/codex-local/tsconfig.json --noEmit` ## Risks - Low risk: the monitor becomes more conservative and may allow a noisy-but-stuck child to run longer, but the configured hard timeout and platform silent-run safety net remain unchanged. - No schema, API, migration, or UI changes. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first. See `CONTRIBUTING.md`. ## Model Used - OpenAI Codex CLI coding agent; runtime model ID and context-window size were not exposed to the agent. Used repository/tool access, code execution, and focused test verification. ## 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>
