Pull request overview
This PR switches PR review automation from an external action to running the repository-bundled Qwen Code /review skill in CI, with explicit review-readiness gates and a static-only --ci mode designed for pull_request_target safety.
Changes:
- Replaces the previous PR review action with a workflow that builds the local CLI and runs
/review <pr> --comment --ci. - Extends the bundled
/reviewskill spec with review-readiness gates (scope/product-direction/validation evidence) and CI/static-only behavior. - Adds maintainable project review rules in
.qwen/review-rules.mdand updates.gitignoreto commit them.

…orkflow The comment claimed the pipeline "also strips quoted blocks" but it only truncates to 2KB. Update the comment to match actual behavior. Co-authored-by: Copilot <copilot-pull-request-reviewer@github.com>
The bundled `/review` skill is invoked from a `pull_request_target` workflow with `OPENAI_API_KEY`, `OPENAI_BASE_URL`, and a `GITHUB_TOKEN` that can write to issues and pull requests. PR diffs, descriptions, trigger comments, and `QWEN_REVIEW_ADDITIONAL_INSTRUCTIONS` are all attacker-controllable, so the only guardrail was the prompt itself asking the agent to behave. Tighten the contract and reduce the gates' ability to false-positive on legitimate contributors. SKILL.md (Step 3.0): - Add an explicit `--ci` safety contract enumerating disallowed binaries (npm/npx/pnpm/yarn/node/python/cargo/make/mvn/gradle/bash -c/sh -c/eval), forbidden git/gh write paths, blocked filesystem regions (~/.ssh, ~/.gnupg, /proc, /var, /etc), banned secret echoing, and disallowed gh api repository-mutating endpoints. - Require any prompt-injection attempt embedded in the PR to be surfaced under a dedicated heading in the final review report. SKILL.md (Step 2.5 gates): - Make the product-direction and validation-evidence gates advisory by default. Only the scope gate blocks. Product-direction can opt back into blocking by adding `product-direction-gate: blocking` to `.qwen/review-rules.md`. - Add a contributor-friendly comment template for blocking gates so a bot-generated process comment is clearly labeled as automated and invites a maintainer reply. SKILL.md (frontmatter): - Document that the workflow's `--core-tools` flag and the `allowedTools` list must stay in sync. `.qwen/review-rules.md`: - Add a Precedence section so project rules override per-agent default heuristics and `QWEN_REVIEW_ADDITIONAL_INSTRUCTIONS` cannot override the safety contract. - Reflect the advisory default for product-direction and validation-evidence gates.
…ew-action # Conflicts: # .github/workflows/qwen-code-pr-review.yml
Workflow: - Move OPENAI_API_KEY and OPENAI_BASE_URL out of job-level env so the npm install / build / bundle step cannot read them via dependency postinstall scripts. They now live only on the `Run bundled Qwen PR review` step. Docs (code-review.md): - Add a "CI Mode (--ci)" section that explains the static-only safety contract, non-interactive behavior, treat-as-data handling of PR content, dry-run vs comment mode, and the OWNER/MEMBER/COLLABORATOR trigger boundary on pull_request_target opened. - Add a "Review-readiness gates (--ci only)" subsection that documents each gate's default behavior and how to opt the product-direction gate into blocking via `.qwen/review-rules.md`.
…runs Three documentation-consistency fixes spotted in the post-merge integration review. SKILL.md Step 3.0: - The "MAY use" allowlist named "gh pr review, gh pr comment" as the Step 9 posting path, but Step 9 actually submits via the Create Review API: `gh api repos/<owner>/<repo>/pulls/<n>/reviews --input <file>`. A `--ci` agent reading the contract literally could refuse the real call. Replace with the actual `gh api` invocation and an explicit "at most one review per run" cap. - Replace the misleading reference to a "cleanup comment defined in Step 11" — Step 11 (worktree cleanup) does not post anything. Move the process comment allowance to Step 2.5 with a "blocking gate only" qualifier. .qwen/review-rules.md Product Direction: - The advisory-default rule I added contradicted the older "should usually produce a process comment" line. An advisory concern goes inside the Step 9 review body (one review), not as a separate `gh pr comment`. Reconcile so the advisory and blocking paths are unambiguous.

No issues found. LGTM! ✅
The workflow has proper author_association checks on all comment/review triggers, the --ci safety contract is comprehensive, the review-readiness gates are well-scoped, and credential scoping is intentionally step-level where it matters. The open Copilot comments (grep boundary for @qwen /review, line-based sed extraction) are minor polish items that don't block merge.

…m source Replace the manual npm ci + build + bundle + preflight steps with the published composite action. Revert the bundled review SKILL.md to vanilla (removing all --ci safety-contract additions that belong at the CLI/action level, not in the skill). Drop smoke mode and the preflight script since qwen-code-action handles its own setup validation.
…t SKILL.md Checkout main branch so the bundled /review skill enters normal (not lightweight) mode — it can find the local git remote, load project rules, and run linters. Move review-rules.md from .qwen/ to .github/ so it doesn't affect local /review runs; copy it to .qwen/ in CI only.
…y error message - Add sed '/./,$!d' to remove leading empty lines when @qwen /review is on its own line with follow-up instructions on subsequent lines. - Clarify the QWEN_PR_REVIEW_MODEL error message to note it maps to the OPENAI_MODEL env var.
Add pull_request_target types (reopened, ready_for_review) so draft-to-ready and reopen automatic review. Add edited types for issue_comment and pull_request_review_comment so editing a comment to include @qwen /review triggers re-review. Update the job-level if condition to match the new actions.

Code Review: PR #4067
Review commit: 204837c368d4d15c7720d03754cb8c3704520911
🔍 Verdict: REQUEST_CHANGES
This PR introduces a well-structured rewrite of the PR review workflow, but has a critical bug that makes the headline feature non-functional, plus several defense-in-depth and correctness issues.
Critical
1. issue_comment events are completely blocked by missing job-level if branch
The on: block declares issue_comment: [created, edited] and the "Resolve PR context" step handles issue_comment in its case statement, but the job-level if condition only covers workflow_dispatch, pull_request_target, pull_request_review_comment, and pull_request_review. There is no github.event_name == 'issue_comment' branch. GitHub evaluates all four branches to false for issue_comment events, so the job is always skipped.
The @qwen /review comment trigger — the PR's headline feature — is completely non-functional.
Fix: Add an issue_comment branch to the job-level if, gated on github.event.issue.pull_request (PR-only) and github.event.comment.author_association:
(github.event_name == 'issue_comment' &&
github.event.issue.pull_request &&
(github.event.comment.author_association == 'OWNER' ||
github.event.comment.author_association == 'MEMBER' ||
github.event.comment.author_association == 'COLLABORATOR'))2. additional_instructions sanitization only covers --comment flag
The sanitization perl -0pe 's/(?<!\S)--comment(?!\S)/--comment/g' wraps only --comment in backticks. Other flags (--ci, --approval-mode, --json, --model, --sandbox, etc.) pass through unsanitized into the prompt.
A maintainer could inject --approval-mode yolo into their @qwen /review comment, altering the review behavior. The author_association gate limits the blast radius, but the sanitization gives a false sense of protection.
Fix: Sanitize all -- prefixed flags:
additional_instructions="$(printf '%s' "$additional_instructions" | sed 's/--[a-zA-Z][a-zA-Z-]*/`&`/g')"Suggestion
3. pull-requests: 'read' may block inline PR review comments
Permissions downgraded pull-requests from 'write' to 'read'. If the bundled action posts inline PR review comments (via the Pull Requests API, which requires pull-requests: write), they will fail with HTTP 403. The review may appear to succeed but produce zero inline comments.
Fix: Restore pull-requests: 'write' if the action posts inline comments, or pass a separate fine-grained token.
4. cancel-in-progress: true silences the fallback comment
When a concurrent event cancels a running review, GitHub sets the job status to "cancelled", not "failure". The fallback step's condition failure() && steps.review.conclusion == 'failure' requires "failure" status, so cancelled runs produce no PR-facing output.
Fix: Either set cancel-in-progress: false, or use a workflow_run completion handler.
5. Dead code in review_mode branches
Both branches of the if [ "$review_mode" = "comment" ] / else set review_prompt="/review $review_target" — identical values. Only should_comment differs.
Fix: Extract the common assignment:
review_prompt="/review $review_target"
should_comment=$([ "$review_mode" = "comment" ] && echo "true" || echo "false")6. Indentation leak in multi-line prompt
The "Additional reviewer focus:" line has 12 leading spaces from YAML block-scalar indentation, preserved verbatim in the shell string sent to the model.
Fix: Left-align the continuation lines:
review_prompt="$review_prompt
Additional reviewer focus: $additional_instructions"Nice to have
- Concurrency key uses
github.event.issue.number— correct but undocumented. Add a comment explaining GitHub maps PR numbers to issue numbers. - No automated tests for the ~300 lines of shell logic. Consider extracting to a testable script with
bats. actionlintvalidation would catch Actions expression errors that Ruby YAML parsing misses.

Critical: issue_comment is missing from this job-level if condition. The on: block declares issue_comment: [created, edited] and the shell script handles it, but this gate blocks all issue_comment events — the @qwen /review trigger is dead on arrival.
Fix: Add this branch:
(github.event_name == 'issue_comment' &&
github.event.issue.pull_request &&
(github.event.comment.author_association == 'OWNER' ||
github.event.comment.author_association == 'MEMBER' ||
github.event.comment.author_association == 'COLLABORATOR'))The github.event.issue.pull_request check ensures only PR comments (not plain issues) trigger the workflow.

issue_comment is already handled in the job-level if: — the github.event_name == 'issue_comment' && github.event.issue.pull_request && (contains(github.event.comment.body, '@qwen /review') || contains(github.event.comment.body, '@qwen /design-gate')) && author_association ... branch. The @qwen /review trigger on PR issue comments is live for OWNER/MEMBER/COLLABORATOR, so it isn't dead on arrival.

Suggestion: cancel-in-progress: true means a concurrent event (e.g., a new push to the PR while a comment-triggered review is running) cancels the first run. GitHub sets the job status to "cancelled", not "failure", so the fallback step's condition failure() && steps.review.conclusion == 'failure' never fires. The PR gets no output at all.
Consider cancel-in-progress: false (queue instead of cancel), or document that cancelled runs produce no PR-facing output.
There was a problem hiding this comment.
Intentional. cancel-in-progress: true matches the other AI reviewers — a newer push should supersede an in-flight review rather than queue duplicates, and the superseding run posts its own result. The failure-fallback comment not firing on a cancelled conclusion is an accepted tradeoff here, not something I want to flip in this PR.

Suggestion: pull-requests: 'read' was downgraded from 'write'. If the bundled action posts inline PR review comments via the Pull Requests Reviews API (POST /repos/{owner}/{repo}/pulls/{n}/reviews), it requires pull-requests: write. With 'read', inline comments will silently fail with HTTP 403.
If the action only produces output for the workflow to post via gh pr comment (Issues API), then 'read' is correct — but add a comment documenting this contract.
There was a problem hiding this comment.
Intentional least-privilege. This workflow posts via gh pr comment (covered by issues: write), not the Pull Request Reviews API, so pull-requests: read is sufficient. The downgrade from write was deliberate so the review workflow can't approve PRs. If the bundled /review flow later needs to post inline review comments, the permission bump should land with that change rather than preemptively.
Add docs/design/code-review/ covering the PR review automation system this branch is building toward: - code-review-design.md (569 lines): problem statement, design principles, 4-stage workflow pipeline, Design Gate spec with PR shape generation and fail modes, Feature PR Readiness Gate, author/maintainer feedback loop with override, historical PR/issue detection, incremental cache wiring, App integration plan, testing strategy, risks. - roadmap.md (179 lines): 7-phase rollout, each phase scoped to an independent PR with acceptance criteria. - compare.md (86 lines): capability comparison vs claude-code, coderabbit, copilot review, cursor bugbot, greptile. The design treats Direction/Scope/History/Validation as workflow preflight gates separate from bundled /review, so direction issues are decided in the first 30s rather than after a full deep pass. Anchors are existing repo artifacts (roadmap.md, architecture.md, docs/design/*) and historical close comments (#3863, #3627), not new team-policy docs.
Listen to pull_request_target.synchronize so author pushes automatically retrigger review, and persist .qwen/review-cache/ via actions/cache so the bundled /review skill's incremental review path can scope subsequent runs to the new commit range instead of evaluating the full PR every time. Cache key uses PR head SHA from gh pr view --json headRefOid, not github.sha, because in pull_request_target context github.sha points at the base branch. Restore is gated on synchronize only so manual @qwen /review and workflow_dispatch keep their force-rerun semantics. Save runs on any pull_request_target event with a successful review. Implements docs/design/code-review/roadmap.md Phase 2.
…ontamination The previous restore-keys prefix `qwen-review-<pr#>-` could still match an older cache after the PR's base ref changed (Update branch from base, or base retarget). Bundled /review would then read the stale lastCommitSha and compute git diff <oldHead>..<newHead>, which after a base-merging "Update branch" includes upstream commits that the PR did not author. Embed both baseRefOid and headRefOid in the cache key. The exact key becomes qwen-review-<pr#>-<base_sha>-<head_sha> and restore-keys narrows to qwen-review-<pr#>-<base_sha>-. A base change now naturally invalidates prior caches for the same PR and forces a full review on the next synchronize. Update docs/design/code-review/code-review-design.md and roadmap.md Phase 2 spec + acceptance criteria to match. Caught by /codex:review (P2 finding).
…lication Two correctness fixes to the Phase 2 cache wiring, both caught by /codex:review. 1. Cache discriminator must be the PR's merge base, not baseRefOid. When the base ref tip has not moved between two reviews but the PR author clicks "Update branch from base", baseRefOid stays the same, the restore-keys prefix still matches the prior cache, and the bundled /review skill computes git diff <oldHead>..<newHead> across upstream commits the PR did not author. The merge base advances on Update branch, rebase, and base retarget — exactly the boundaries cache must invalidate on. Compute merge_base via gh api compare and use it in the cache key. 2. Save cache only after the review summary comment is published. bundled /review can succeed (model output captured) and yet the subsequent gh pr comment can fail (rate-limit, network, deleted PR). If save advances the cache before the comment lands, the next synchronize either short-circuits on "No new changes" or reviews only the later diff, and the unpublished findings are lost forever. Gate save on steps.post-summary.outcome == 'success' so cache advancement tracks comment delivery, not just model success. Move the save step to after the post-summary step. Update docs/design/code-review/code-review-design.md and roadmap.md Phase 2 spec + acceptance criteria to reflect both invariants.
The compare endpoint can fail to resolve fork head SHAs in the base repo's namespace, which would let `set -euo pipefail` abort the size step before the existing is_cross_repository handler has a chance to post the fork-rejection comment. Guard the merge_base computation on `is_cross_repository != "true"` and let the cross-repo branch carry an empty merge_base_sha through the rest of the step. Forks set should_review=false anyway, so they never reach the cache restore/save steps where merge_base would be needed. Caught by /codex:review (P2 finding).

[Critical] In .github/workflows/qwen-code-pr-review.yml, pull_request_review events only pass the job gate when the review body contains @qwen /review; @qwen /design-gate is accepted for issue comments and review comments, and resolveReviewContext() also supports pull_request_review bodies for design-gate reruns. A maintainer submitting a review with @qwen /design-gate will therefore get a silent no-op at the workflow level. Add the same @qwen /design-gate condition used by the other comment-triggered events.

[Critical] GitHub Actions expression injection via LLM output.
steps.review.outputs.summary is produced by the LLM from PR body content (user-controlled). When interpolated via ${{ }} in env:, GitHub's expression engine re-evaluates any ${{ }} tokens the LLM emitted. A crafted PR body could induce the model to output ${{ secrets.REVIEW_OPENAI_API_KEY }} or ${{ github.token }}, leaking secrets into the shell step's environment or the posted PR comment.
This is a different attack surface from the LLM prompt injection at design-gate.mjs:26 — this targets the GitHub Actions expression evaluation layer.
Suggested fix: Write the action's summary to a file instead of using expression interpolation, or base64-encode the output to break the expression chain:
# Have the action write summary to a file path
- name: 'Post review summary comment'
env:
PR_NUMBER: '${{ steps.pr.outputs.number }}'
run: |
# Read from action output file, not ${{ }} expression
cat "${{ steps.review.outputs.summary_file }}" > comment.md

I don't think this is exploitable as described. REVIEW_SUMMARY is assigned in env: from ${{ steps.review.outputs.summary }} and consumed as the shell variable "$REVIEW_SUMMARY". GitHub Actions substitutes ${{ }} exactly once when building the env value; a literal ${{ ... }} string inside that value is not recursively re-evaluated. Routing untrusted output through env: instead of interpolating it directly into the run: script is the documented safe pattern, which is what this step already does.

[Critical] --yolo + full process.env creates a remote code execution chain via indirect prompt injection.
Three dangerous properties combine here:
--yoloauto-approves all tool use includingrun_shell_commandrunQwenJsonpasses the fullprocess.env(containingGITHUB_TOKEN,REVIEW_OPENAI_API_KEY) to the subprocessbuildDesignGateLlmPromptembeds closed-unmerged PR comments (fromgh-search.mjs) directly into the prompt
An attacker who is merely a collaborator can plant a prompt injection payload in a comment on any closed-unmerged PR. When a future PR matching the same keywords is reviewed, the history scan fetches the planted comment, embeds it in the Design Gate prompt, and the --yolo LLM could execute arbitrary commands with full secrets.
Suggested fix:
- Replace
--yolowith a restricted tool allowlist (Design Gate only needs JSON output, not shell access) - Pass only the required env keys (
OPENAI_API_KEY,OPENAI_BASE_URL,OPENAI_MODEL) instead of the fullprocess.env - Sanitize or truncate comment bodies from history scan results before embedding

Acknowledged. The Design Gate LLM call is opt-in (QWEN_DESIGN_GATE_LLM), and 36043db adds explicit untrusted-data fencing around the embedded PR/history content. A runtime shell-command allowlist (instead of relying on the prompt) plus a reduced subprocess env is the same hardening already tracked separately for the workflow-level --approval-mode yolo concern — I'd rather land it once, consistently, than partially here.

[Suggestion] npx -y @latest fallback is a supply chain risk in CI and non-reproducible.
@latest resolves to whatever is currently published on npm. If the package is compromised (maintainer account breach, dependency confusion), arbitrary code executes in the CI runner with full secrets. Additionally, the same commit could pass review on Monday and fail on Tuesday after a breaking npm publish.
Also: runQwenJson only catches ENOENT (line 50). If qwen exists but fails for any other reason (wrong version, permission error), the npx fallback is never attempted, and there's no log indicating which execution path was taken.
Suggested fix: Pin to a specific version, pre-install the CLI in the runner image, or read the version from a repo variable. Add logging for both execution paths and wrap non-ENOENT errors.

This path is a fallback that only runs when the qwen binary isn't on PATH; the primary path is the pinned QwenLM/qwen-code-action SHA, and the fallback is already overridable via QWEN_DESIGN_GATE_NPX_PACKAGE. Pinning the default is a reasonable follow-up but isn't load-bearing for the normal CI path.

[Suggestion] Dual-language gate logic will drift. The YAML if: filter and Node.js pullRequestTargetMode() (review-context-core.mjs:119) implement the same event-action gate in two different languages with no mechanical coupling.
The YAML checks github.event.action == 'edited' && github.event.changes.body. The Node.js checks Boolean(event.changes?.body). Today they agree, but they live in different files, different languages, and are edited by different people. If someone tightens one without the other, the job either silently never runs or runs and decides not to — with no error in either case.
Suggested fix: Consolidate: make the YAML if: minimal (just event-type + author_association) and let the Node.js script own all gating logic. Or add a test fixture asserting both paths produce the same should-run decision.

Real maintenance risk, agreed. Both sides are kept in sync in 36043db (the YAML if: and pullRequestTargetMode both gate on changes.body || changes.title). Collapsing the YAML filter to a thin pre-check that defers to the Node resolver is the right structural fix, but it's broader than this PR.

[Suggestion] .github/workflows/qwen-code-pr-review.yml line 52: The workflow-level gate accepts @qwen /design-gate for issue_comment and pull_request_review_comment, and resolveReviewContext() also treats @qwen /design-gate in pull_request_review bodies as a gate-only rerun. But this job-level condition only checks contains(github.event.review.body, '@qwen /review'), so a submitted review body containing only @qwen /design-gate is filtered out before the resolver runs.
Consider keeping this condition in sync with the other comment sources and the resolver:

body.toLowerCase() throws TypeError when body is null. gh pr view --json body returns body: null for PRs with no description. The default parameter body = '' only catches undefined, not null. Other functions in this PR already guard against this (e.g., isFeatureLike uses pr.body ?? ''), but extractKeywords is missing the guard.

Errors are caught and [] is returned, but failures are never pushed to searchErrors. The degraded flag only checks searchErrors, which tracks search-phase API failures — not comment-fetch failures.
Under GitHub API rate limiting, searches succeed but comment data is lost. Closed-unmerged PRs whose blocking direction decision lives only in a comment are silently misclassified, and no degraded advisory is emitted. The Design Gate can miss hard "by design" rejections.
Suggested fix: track comment-fetch errors and include them in the degraded check:
const commentErrors = [];
async function issueComments({ repo, number }) {
try { return await ghJson([...]); }
catch (error) { commentErrors.push(error.message); return []; }
}
// After comment-fetch phase in scanHistory:
if (commentErrors.length > 0) {
classified.findings.unshift({ kind: 'history_comment_fetch_degraded', severity: 'advisory', ... });

[Critical] Failure fallback comment never fires when upstream steps fail
steps.review.conclusion == 'failure' only matches when the review step itself fails. If any upstream step (pr-shape, history-scan, design-gate) fails, the review step is skipped (not failed), so its conclusion is 'skipped'. failure() returns true but the second condition fails — no fallback comment is posted. PR authors see only "Some checks were not successful" with zero explanation.

[Critical] parseUnifiedDiff ignores removed lines — blind to API removals
The parser records addedLines but only counts deletions without storing removed line content. detectPublicSurfaceChanges iterates only file.addedLines. A PR that removes a public export (breaking change) produces an empty public_surface_changes array, bypassing the high-risk gate in design-gate-core.mjs.
Breaking API removals are the highest-risk changes possible, yet the shape analysis is invisible to them. Same gap applies to detectDependencyChanges — removing a dependency from package.json goes undetected.
Suggested fix: add a removedLines array to parseUnifiedDiff, then scan both addedLines and removedLines in downstream detectors.

[Suggestion] commandLines fence detection doesn't track delimiter type or handle HTML/indented blocks
The single inFence boolean toggles on both ``` and ~~~ without tracking which opened the block. Per CommonMark spec, a backtick-fenced block can only be closed by backticks. A backtick-fenced block containing a ~~~ line prematurely exits fence mode, potentially interpreting @qwen commands inside the remaining fenced content as live commands.
Also missing: HTML block stripping (<pre>, <details>, <!-- -->) and 4-space indented code blocks, both valid Markdown code contexts.
Suggested fix: track the opening fence delimiter type and only close with the same type. Add HTML block and comment stripping.

[Suggestion] N+1 query pattern in withIssueComments + no concurrency cap
Each PR triggers an individual gh api repos/.../issues/{number}/comments call via Promise.all. With limit=10, this fires up to 10 concurrent HTTP requests immediately after the search phase (which itself fires 5+ concurrent gh search calls). The combined burst of 15+ API requests can self-trigger GitHub secondary rate limits, which then causes issueComments to silently return [] (see Critical finding above).
Suggested fix: add a concurrency cap (max 3-4 concurrent gh calls) using a semaphore pattern, or batch into a single GraphQL query.

[Suggestion] Diff header regex drops files with git-quoted paths
/^diff --git a\/(.+?) b\/(.+)$/ doesn't match quoted paths like "a/src/caf\303\251.ts" that git emits when core.quotePath=true (the default) for paths containing non-ASCII characters. Such files are silently absent from changed_files, public_surface_changes, and dependency_changes, causing isHighRisk() and isDocsOnly() to evaluate against an incomplete file list.
Suggested fix: accept optional leading " in the regex, or run git config core.quotePath false before diff generation.

[Suggestion] gate_only events post Design Gate comments even on PASS
For pull_request_target.edited events, gate_only = 'true' satisfies this condition regardless of gate status. Every PR body/title edit triggers the full Design Gate pipeline (shape → history scan → LLM call) and posts a PR comment, even when the gate returns PASS. On actively-edited PRs this creates a stream of redundant "Design Gate: PASS" comments.
Consider gating the comment on status != 'PASS' when gate_only is true, or collapsing repeated PASS results into the workflow summary only.

[Critical] These new .github/scripts/**/*.mjs helpers are not covered by the repo's Node-script ESLint override, so npm run lint:ci -- --quiet now fails on the added scripts with no-undef for process / console (for example this line, plus the new console.log calls and other helpers). The existing override in eslint.config.js only covers ./scripts/**/*.js, ./scripts/**/*.mjs, esbuild.config.js, and packages/*/scripts/**/*.js.
Please extend that override to include the new GitHub helper scripts, e.g. add .github/scripts/**/*.mjs (and .github/scripts/**/*.js if desired) so the repository lint job can pass.

[Critical] This pull_request_target job invokes the agent action with review secrets, but the action inputs below do not pass any restrictive project settings/tool policy. Same-repository PR content, PR bodies, and comments all flow into the review prompt, so a prompt-injection or future repo-local config change can run the bundled agent with broader defaults than this security-sensitive workflow should allow.
Please pass an explicit locked-down settings payload (or the action's equivalent) for this PR-review path: enable sandboxing where supported and restrict tools to the minimum read/search/static-review surface needed by /review, rather than relying on the action defaults while secrets are present.

[Critical] Matching placeholder headings like Expected result: makes an unfilled PR template count as validation evidence. With a high-risk workflow change and a body that only contains the default validation section (Commands run, # paste commands here, Expected result:, Observed result:, etc.), evaluateDesignGate() returns PASS; with an empty body it correctly returns BLOCK.
Please strip the default validation placeholders/headings before applying these patterns, or require non-placeholder content after the fields. Add a regression test using the unchanged PR template body so high-risk workflow/security PRs cannot bypass the validation gate by leaving the template blank.

[Suggestion] The Design Gate treats workflow YAML and custom actions as high-risk, but it does not include the new .github/scripts/** helpers that actually implement PR shape detection, history scanning, LLM gating, and review-context resolution for this privileged workflow. A future PR that changes only these helper scripts can avoid the high-risk validation path even though it can change when the deep review runs, when it is blocked, or when overrides are accepted.
Please include .github/scripts/ in HIGH_RISK_PATH_PATTERNS and add a regression test showing that a .github/scripts/*.mjs change without validation evidence is classified as blocking.

[Critical] LLM prompt injection via <untrusted> XML boundary break.
buildDesignGateLlmPrompt embeds pr.title and pr.body (user-controlled) directly between <untrusted>...</untrusted> XML tags via JSON.stringify with no XML escaping. JSON.stringify does not escape <, >, or /. If a PR title or body contains </untrusted>, the XML boundary closes early, and subsequent structured data (shape, history, anchors) gets interpreted by the LLM as prompt instructions instead of data to classify.
An attacker can craft a PR body containing </untrusted> to completely control the Design Gate LLM output (return arbitrary blocking findings or empty []).

[Critical] run() discards stderr — all gh/qwen/npx diagnostic output is lost.
run() only destructures { stdout } from execFileAsync, silently discarding stderr. When gh search prs fails due to API rate limiting, gh writes errors to stderr (e.g., "API rate limit exceeded") but returns empty array to stdout. Callers cannot distinguish "no results" from "rate limited."
This affects all run() call sites in gh-search.mjs (all gh search/gh api calls), llm.mjs (runQwenJson), and the entry-point scripts.

[Critical] hasDifferentiatingRationale can be trivially bypassed, making the entire blocking history gate ineffective.
The regex \b(why this is different|...|rationale|context changed|new constraint)\b matches bare words like "rationale" and "context changed" in any PR description. A PR author simply writing "Rationale: this is a simple fix" downgrades ALL blocking history findings to advisory, without needing to actually explain why the new approach differs from prior rejected PRs.
The regex performs no substantive check on whether the rationale actually addresses why a previously-rejected direction is now safe to reattempt.

[Critical] Design Gate LLM JSON sandbox has a backdoor through error handling — unsandboxed LLM output leaks into the final review prompt.
When the Design Gate LLM is prompt-injected into producing non-JSON output:
parseJsonFromText()(line 48-52) captures up to 600 chars of raw LLM output in the error message viasnippet(text)maybeRunLlm()(design-gate.mjs:35-44) catches this and creates an advisory finding whosemessageincludes the raw LLM output- If gate status is ADVISORY_ONLY (not BLOCK),
formatPromptAppend()appends this finding to the final deep-review prompt
The JSON-output constraint was intended to sandbox the untrusted LLM call, but the error-handling path provides a backdoor that feeds unsandboxed LLM output directly into the downstream AI reviewer.

[Critical] issueComments silently loses all comment data for PRs with >30 comments — direction decisions are missed.
gh api --paginate --jq '[.[] | {body, url, createdAt}]' produces multiple independent JSON arrays when pagination triggers (one per page), e.g., [{...}, ...]\n[{...}, ...]. This concatenation is not valid JSON — JSON.parse throws SyntaxError, which the try-catch silently catches and returns [].
Any closed PR with >30 comments (GitHub API default page size) has ALL its comments dropped. Direction-deciding comments like "decided not to ship" are invisible to Design Gate, causing blocking signals to be missed.
