From 46f32ed33fdf28a90fa06146902d389c1009db19 Mon Sep 17 00:00:00 2001 From: Dotta <34892728+cryppadotta@users.noreply.github.com> Date: Sun, 8 Nov 2026 05:50:30 -0600 Subject: [PATCH] fix(sentry): stop treating short host settings as credentials in run-failure redaction (#20013) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - When an agent run fails, Paperclip sends a redacted failure report to Sentry so the team can fix the cause > - Redaction treats the server's own environment values as possible secrets and removes them wherever they appear in the report > - Since #19461, every value under an environment name the allowlist does not know counts as a secret, even very short ones such as `vi`, `RUN`, `off` or `1` > - On a host with such settings, the report text is damaged: `service` becomes `ser***REDACTED***ce`, and a `1` anywhere can vanish. One server test failed on every such host, while CI (which has no such values) stayed green > - This pull request keeps the fail-closed rule for an agent's configured environment, and requires a plausible credential in the server's own environment > - The benefit is that Sentry reports stay readable on every host, and real credentials stay private ## Linked Issues or Issue Description Refs #19461 (introduced the catch-all), #14585 (added the failing test). **What happened?** `heartbeat-process-recovery.test.ts` › "redacts opaque environment-bound credentials from Sentry diagnostics: result" failed locally on `master`: `expected 'ser***REDACTED***ce' to be 'service'`. Instrumentation showed that the server's own `process.env` contributed these redaction values: `["false","67591","true","0x0","RUN","off","vi","64","1","0","8"]`. They came from a desktop agent session's environment. **Expected behavior** Short host settings are not credentials. Declared, secret-named and credential-shaped values stay private. An agent's configured environment keeps its fail-closed rule. **Steps to reproduce** Run that test on a machine whose environment contains `SOME_UNKNOWN_NAME=vi`. ## What Changed - `packages/adapter-utils/src/command-redaction.ts`: `collectDiagnosticEnvironmentSecrets` gets an option, `{ hostProcess: true }`. With it, an undeclared value under an unrecognized name is collected only in these cases: - it has at least 8 characters and is not a bare number, hex number or boolean-like word; or - its name has a credential segment: `TOKEN`, `SECRET`, `PASSWORD`, `BEARER` or `PRIVATE`, or a final `KEY` or `KEY_ID`. Without the option, behavior is unchanged. - `server/src/services/run-failure-report.ts`: the report collects the server's own `process.env` with `hostProcess: true`. The agent's configured environment (`heartbeat.ts`) and the provider environment (`terminal-session-failure.ts`) keep the default. ## Verification - `command-redaction.test.ts` (42 pass). The new test fails on `master` and passes here. It checks three things: the host's short values are not collected; a short value under `AWS_ACCESS_KEY_ID` and a long opaque value stay private; and an agent binding `CUSTOM_BINDING: "1"` stays private. - `run-failure-diagnostics.test.ts` (135 pass, unchanged). These tests pin the agent-environment fail-closed rule. - `heartbeat-process-recovery.test.ts` › "redacts opaque environment-bound credentials…": both modes pass here. The `result` mode failed on unchanged `master` on this host. - The adapter-utils and server typechecks pass. ## Risks - The server's own environment now leaves out a non-credential-named value that is shorter than 8 characters or is a bare number or boolean, for example `MY_PIN=1234`. Values under credential names, declared secrets and credential-shaped values are still redacted. - No Telemetry path changes; this is the Sentry run-failure report. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use and code execution in Claude Code. ## 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 - [x] 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 --- .../src/command-redaction.test.ts | 24 +++++++++ .../adapter-utils/src/command-redaction.ts | 50 ++++++++++++++++++- .../__tests__/run-failure-diagnostics.test.ts | 16 +++++- .../src/services/run-failure-diagnostics.ts | 30 +++++++++-- server/src/services/run-failure-report.ts | 7 ++- 5 files changed, 118 insertions(+), 9 deletions(-) diff --git a/packages/adapter-utils/src/command-redaction.test.ts b/packages/adapter-utils/src/command-redaction.test.ts index 73ed4fed09d..a29ce47a1fa 100644 --- a/packages/adapter-utils/src/command-redaction.test.ts +++ b/packages/adapter-utils/src/command-redaction.test.ts @@ -12,6 +12,7 @@ describe("explicit diagnostic credential forms", () => { import { REDACTED_COMMAND_TEXT_VALUE, collectDiagnosticEnvironmentSecrets, + collectHostEnvironmentTokenSecrets, looksLikeCredentialJwt, redactDiagnosticText, redactCommandText, @@ -213,6 +214,29 @@ describe("diagnostic environment secret selection", () => { expect(new Set(selected)).toEqual(new Set([jwt, pem, key, "safe"])); }); + // Host env of a desktop agent session: short ordinary values under names + // the allowlist does not know.
