fix(triage): make unattended PR review static — read CI via API, never run PR code - #7646
Conversation

Thanks for the PR! Template: the body uses its own headings ("What & why", "Change", "Verification", "Merge order") rather than the template's exact sections, but the content is thorough and covers the intent. Not blocking on heading names for a skill-docs PR. Problem: observed, with evidence. The PR references #7632 where the triage agent relayed an author's self-reported 8/8 E2E as if it were verification, and identifies a concrete security vector — executing untrusted PR code in a CI job that carries a write PAT. This is a real, well-known attack surface (prompt injection → token exfiltration), not theoretical hardening. Direction: clearly aligned. This hardens the maintainer's own triage tooling against a real security risk and improves the reliability of test evidence. CHANGELOG: no direct reference (this is internal tooling, not a product feature), but the area is directly relevant to the project's CI/automation infrastructure. Size: not applicable — no core paths touched. All 3 changed files are under Approach: the scope feels right. Scoping testing behavior by trigger (CI reads results via API, local runs tmux as before) is the minimal, well-targeted fix. The companion workflow PR handles enforcement via tool/permission denials — this PR handles the skill instructions. Every edit in the diff serves the stated goal; no drive-by changes. The Moving on to code review. 🔍 中文说明感谢贡献！ 模板：PR 正文使用了自己的标题（"What & why"、"Change"、"Verification"、"Merge order"），而非模板的精确章节名，但内容详尽，覆盖了模板的意图。对于 skill 文档类 PR，不因标题名称而阻止。 问题：已观测到，有证据。PR 引用了 #7632，其中 triage agent 将作者自报的 8/8 E2E 结果当作验证转述；并指出了具体的安全风险——在携带写权限 PAT 的 CI job 中执行不可信的 PR 代码。这是真实的攻击面（prompt 注入 → token 泄露），不是理论性加固。 方向：明确对齐。这加固了维护者自己的 triage 工具，防范真实的安全风险，并提升测试证据的可靠性。CHANGELOG：无直接引用（这是内部工具，不是产品功能），但该领域与项目的 CI/自动化基础设施直接相关。 规模：不适用——未触及核心路径。全部 3 个变更文件都在 方案：范围合理。按触发来源区分测试行为（CI 通过 API 读取结果，本地照旧跑 tmux）是最小且精准的修复。配套的 workflow PR 通过 tool/permission 设置来强制执行——本 PR 处理 skill 指令。diff 中每处改动都服务于既定目标，没有顺手改动。 进入代码审查 🔍 — Qwen Code · qwen3.8-max-preview Reviewed at |
Code reviewIndependent proposal: given the problem (triage agent executes untrusted PR code in a CI job carrying a write PAT, and relays author self-reported results as evidence), I would: (1) add a clear prohibition rule in SKILL.md, (2) replace tmux-based testing in CI with reading CI check results via the GitHub API, (3) scope tmux to local invocation only, (4) update issue-workflow.md consistently, (5) add a rule against presenting author's self-reported results as evidence, (6) switch Comparison with the diff: the PR matches this proposal exactly. No simpler path missed. All suggestions from the previous review round have been addressed in the latest push:

Confidence: 5/5 — clean across every stage; the security rationale is sound, the implementation is minimal and correct, and all prior review feedback has been addressed. This PR fixes a real problem with evidence: the triage agent was executing untrusted PR code in a CI job carrying a write PAT, and #7632 showed the author-claim relay issue in action. The fix is exactly what I would have proposed — scope testing by trigger, read CI results via API in unattended runs, keep tmux for local only. Every edit in the diff earns its place; there's no bloat, no drive-by refactors, no over-engineering. The latest push addressed every suggestion from the previous review round: the The companion workflow PR #7647 (tool/permission denials) is the enforcement side; this PR is the instruction side. Merging this first, as the PR body suggests, makes sense — the agent should know the rules before the enforcement kicks in. If I had to maintain this in six months, I'd thank the author. The triage workflow is safer and the test evidence model is more honest. 中文说明置信度：5/5 — 每个阶段都很干净；安全理由充分，实现最小且正确，所有先前审查反馈均已处理。 这个 PR 修复了一个有证据的真实问题：triage agent 在携带写权限 PAT 的 CI job 中执行不可信的 PR 代码，#7632 展示了作者声称结果被转述的实际案例。修复方案与我的独立提案完全一致——按触发来源区分测试行为，无人值守运行通过 API 读取 CI 结果，tmux 仅限本地。diff 中每处改动都有其必要性，没有冗余、没有顺手重构、没有过度工程。 最新推送处理了上一轮审查的所有建议：多页 check-runs 的 配套的 workflow PR #7647（tool/permission 拒绝）是执行侧；本 PR 是指令侧。如 PR 正文所建议，先合并本 PR 是合理的——agent 应该先知道规则，然后才启动强制执行。 如果半年后我要维护这些文件，我会感谢作者。triage 工作流更安全了，测试证据模型也更诚实了。 — Qwen Code · qwen3.8-max-preview Reviewed at |

[Critical] The sed pattern uses /job/ (singular) but GitHub Actions details_url uses /jobs/ (plural) — e.g. …/actions/runs/12345/jobs/67890. The expression s#.*/job/## does not match, so JOB_ID becomes the full URL string. The [ -n "$JOB_ID" ] guard passes (non-empty), and gh api "repos/$REPO/actions/jobs/<full-URL>/logs" 404s. The Stage 2 comment is posted without the failing job's log excerpt — the very evidence this section is designed to surface. — Failure scenario: any PR with a failing CI check → log excerpt silently missing from the triage comment.

Verified against the live API — the check-run details_url for an Actions job uses singular /job/, not /jobs/:
$ gh api ".../check-runs?per_page=100" --paginate --jq '.check_runs[].details_url' | grep -oE '/jobs?/' | sort | uniq -c
418 /job/
(418/418 real check-runs on this repo — e.g. .../actions/runs/30064620665/job/89393060859.) The gh api .../actions/jobs/<id>/logs endpoint is plural, but the details_url path segment is singular, so sed 's#.*/job/##' extracts the id correctly. Confirmed end-to-end in a real triage run (extracted 89384467683, then gh api .../jobs/89384467683/logs returned the log). Switching to /jobs/ would make the strip a no-op and 404 the fetch — the exact failure this comment describes, but inverted.
Keeping /job/. I did adopt the caching half of this thread (fetch check-runs once, read locally) in the latest push.

…r run PR code The triage skill instructed the review agent to run the PR's tests (npm/tmux) in the CI worktree. That executes untrusted PR code in a job whose environment carries a write PAT, and the "tests pass" evidence it produced came from self-run commands rather than the PR's own CI. Scope the behavior by trigger: - Unattended CI runs (GITHUB_EVENT_NAME set): never build or run PR-derived code. Stage 2 test evidence comes from the PR's own CI checks via the API (check-runs + the failing job's log excerpt). Real-scenario TUI coverage is left to the isolated `@qwen-code /tmux` job. - Local invocation only (no GITHUB_EVENT_NAME): drive the app in tmux as before. Also: never present the author's self-reported results under a testing heading — attribute them as a claim if referenced at all; and fetch the CHANGELOG via `gh api` instead of `curl`. The companion workflow change that enforces these restrictions with tool/permission settings should merge after this, so its npm/curl denials never surprise the agent.

[Suggestion] jq -s 'add' flattens paginated arrays correctly when each page outputs a valid array. If an API page returns a non-array (rare API error), add will fail. Consider adding // empty fallback or wrapping in error handling — but given --paginate + --jq executes jq per page independently, this is an extremely unlikely edge case. Non-blocking.

LGTM. Critical security hardening — prevents executing untrusted PR code in CI. Trust boundary well-defined (GitHub metadata trusted, log body untrusted). API-based CI evidence fetching is correct. One inline nit on jq pagination edge case.

[Suggestion] jq -s 'add' produces null when gh api produces no stdout (e.g. gh api exits non-zero due to bad SHA, network error, or expired token).

[Suggestion] select(.details_url | test("/job/")) errors when any failed check_run has details_url: null — jq's test() cannot match against null input (null cannot be matched, as it is not a string), aborting the entire filter so no JOB_ID is extracted. — Failure scenario: a failed third-party check with null details_url → jq exits 5 → JOB_ID empty → log fetch skipped → Stage 2 comment lacks the failing job's diagnostic excerpt.

What & why
During Stage 2 the triage skill instructed the review agent to run the PR's tests (
npm, tmux) in the CI worktree. Two problems in an unattended run:Change
Scope testing behavior by trigger:
GITHUB_EVENT_NAMEset): never build or run PR-derived code. Stage 2 test evidence now comes from the PR's own CI checks via the API —check-runsplus the failing job's log excerpt. Real-scenario TUI coverage is left to the isolated@qwen-code /tmuxjob.GITHUB_EVENT_NAME): drive the app in tmux exactly as before.Also:
gh apiinstead ofcurl.Verification
Ran the real triage skill end-to-end against #7632 with the
qwen3.8-max-previewmodel (the CI review model) through a write-blockingghshim, so nothing posted to the PR. Across two model runs the agent:npm/node/vitest),check-runs+ the failing job's logs exactly as intended,Merge order
The companion workflow PR #7647 enforces these restrictions with tool/permission settings that deny
npm/node/curl. Merge this PR first so those denials never surprise the agent.中文说明
改动内容与原因
triage skill 在 Stage 2 让 review agent 在 CI worktree 里跑 PR 的测试(
npm、tmux)。无人值守运行下有两个问题:改动
按触发来源区分测试行为:
GITHUB_EVENT_NAME):绝不构建或运行 PR 代码。Stage 2 的测试证据改为通过 API 读 PR 自身的 CI check ——check-runs加上失败 job 的日志片段。真实场景 TUI 验证交给隔离的@qwen-code /tmuxjob。GITHUB_EVENT_NAME):照旧用 tmux 驱动应用。另外:
gh api拉取,不用curl。验证
用
qwen3.8-max-preview(CI 实际使用的 review 模型)对 #7632 端到端跑了真实 triage skill,并通过一个写拦截的ghshim 保证不向 PR 发任何内容。两轮模型运行中,agent:npm/node/vitest);check-runs+ 失败 job 日志获取 CI 证据;合并顺序
配套的 workflow PR #7647 用 tool/permission 设置来强制这些限制(会 deny
npm/node/curl)。请先合并本 PR,这样那些 deny 才不会让 agent 意外受阻。
