Prioritize bugs, performance regressions, safety issues, and pattern violations over style nitpicks. **3 important comments > 15 nitpicks.** Flag severity clearly in every comment: - ❌ **error** — Must fix before merge. Bugs, security issues, broken patterns. - ⚠️ **warning** — Should fix. Performance issues, missing validation, inconsistency with patterns. - 💡 **suggestion** — Consider changing. Style, readability, optional improvements. ## Workflow ### 1. Identify the PR If triggered from an agentic workflow (slash command on a PR), use the PR from the event context. Otherwise, extract `owner`, `repo`, `pr_number` from a URL or reference provided by the user. Formats: `https://github.com/{owner}/{repo}/pull/{number}`, `{owner}/{repo}#{number}`, or bare number (defaults to `dotnet/android-tools`). ### 2. Gather context (before reading PR description) ``` gh pr diff {number} --repo {owner}/{repo} gh pr view {number} --repo {owner}/{repo} --json files ``` For each changed file, read the **full source file** (not just the diff) to understand surrounding invariants, call patterns, and data flow. If the change modifies a public/internal API or utility, search for callers. Check whether sibling types need the same fix. **Prefer existing repo patterns.** Before suggesting new infrastructure, grep for established patterns (`ArrayPool`, `ObjectPool`, `MemoryStreamPool`, `ProcessUtils`) and follow those. **Form an independent assessment** of what the change does and what problems it has *before* reading the PR description. ### 3. Incorporate PR narrative and reconcile ``` gh pr view {number} --repo {owner}/{repo} --json title,body ``` Now read the PR description and linked issues. Treat them as claims to verify, not facts to accept. Where your independent reading disagrees with the PR description, investigate further. If the PR claims a performance improvement, require evidence. If it claims a bug fix, verify the bug exists and the fix addresses root cause — not symptoms. ### 4. Check CI status ``` gh pr checks {number} --repo {owner}/{repo} ``` Review the CI results. **Never post ✅ LGTM if any required CI check is failing or if the code doesn't build.** If CI is failing: - Investigate the failure. - If the failure is caused by the PR's code changes, flag it as ❌ error. - If the failure is a known infrastructure issue or pre-existing flake unrelated to the PR, note it in the summary but still use ⚠️ Needs Changes — the PR isn't mergeable until CI is green. ### 5. Load review rules Based on the changed files from step 2, load the appropriate rule files from `references/`: **Always load:** - `references/repo-conventions.md` — repo-specific patterns and conventions - `references/ai-pitfalls.md` — common AI code generation mistakes - `references/security-rules.md` — security review checklist **Conditionally load:** - `references/csharp-rules.md` — if any `.cs` files changed - `references/msbuild-rules.md` — if any `.targets`, `.props`, or `.projitems` files changed, or if changed `.cs` files are under `src/Microsoft.Android.Build.BaseTasks/` - `references/testing-rules.md` — if any files under `tests/` changed or files with `Test` in the path changed ### 6. Analyze the diff For each changed file, check against the review rules. Record issues as: ```json { "path": "src/Example.cs", "line": 42, "side": "RIGHT", "body": "..." } ``` Constraints: - Only comment on added/modified lines in the diff — the API rejects out-of-range lines. - `line` = line number in the NEW file (right side). Double-check against the diff. - One issue per comment. - **Don't pile on.** If the same issue appears many times, flag it once with a note listing all affected files. - **Don't flag what CI catches.** Skip compiler errors, formatting the linter will catch, etc. - **Avoid false positives.** Verify the concern actually applies given the full context. If unsure, phrase it as a question rather than a firm claim. ### 7. Post the review Post your findings directly: - **Inline comments** on specific lines of the diff with the severity, category, and explanation. - **Review summary** with the overall verdict (✅ LGTM, ⚠️ Needs Changes, or ❌ Reject), issue counts by severity, and positive callouts. If no issues found **and CI is green**, submit with one or two 💡 suggestions on key implementation lines and a positive summary. **Always post at least one inline comment** — the review submission framework requires it. **Copilot-authored PRs:** If the PR author is `Copilot` (the GitHub Copilot coding agent) and the verdict is ⚠️ Needs Changes or ❌ Reject, prefix the review summary with `@copilot ` so the comment automatically triggers Copilot to address the feedback. Do NOT add the prefix for ✅ LGTM verdicts. ## Comment format ``` 🤖 {severity} **{Category}** — {What's wrong and what to do instead.} _{Rule: Brief name (Postmortem `#N`)}_ ``` Where `{severity}` is ❌, ⚠️, or 💡. Always wrap `#N` in backticks so GitHub doesn't auto-link to issues. **Categories:** Target framework · Async pattern · Resource management · Error handling · Security · Code organization · Naming · Performance · Pattern · YAGNI · API design · Code duplication · Testing · Documentation --- > Source: [dotnet/android-tools](https://github.com/dotnet/android-tools) — distributed by [TomeVault](https://tomevault.io).
