Review Agent — Autonomous PR Review

Reads a PR diff, cross-references the full knowledge base, posts inline comments on specific

issues, and leaves an overall verdict. Zero user input required.

Invoke as:

  • /review <pr-number-or-url> — review a specific PR
  • /review — review the open PR on the current branch

For creating PRs use /create-pr. For CLI version bumps use /pac-cli-update.


Core rule: never ask, always decide

| Condition | Action |

| --------- | ------ |

| Line-level issue (wrong pattern, bug risk, breaking change) | Post inline comment on that line |

| File-level concern (missing test, architecture violation) | Post inline comment on first line of file |

| Overall concern (security, missing checklist item) | Add to overall review body |

| No issues in a section | Skip the section — don't pad the review |


Step 1 — Sync knowledge if stale

grep "## Last sync" memory/ado-knowledge.md 2>/dev/null | tail -1

If last sync was > 7 days ago or file missing: run /knowledge-sync inline, then continue.


Step 2 — Resolve PR and classify type

# Resolve PR number, head SHA, base branch, changed files
gh pr view <number-or-url> --json number,title,body,headRefOid,baseRefName,author,url 2>&1
gh pr checks <number-or-url> 2>&1
gh pr view <number-or-url> --json baseRefName,files,author \
  --jq '{base:.baseRefName, author:.author.login, files:[.files[].path]}' 2>&1

Capture: PR_NUMBER, HEAD_SHA, BASE_BRANCH.

Classify the PR type — determines which checks run:

| Changed files | PR type | Checks |

| ------------- | -------- | ------ |

| nuget.json + extension/overview.md only | PAC CLI bump | Step 3a |

| package.json + package-lock.json only | npm dep update | Step 3b |

| package.json + ALL task.json files | Node target update | Step 3b + Step 5 |

| src/tasks/*/index.ts or selective task.json | Feature / new input | Step 5 (full) |

| Base = release/stable (any type) | Release branch PR | Step 3c first, then type check |


Step 3 — Type-specific checks (run the section matching the PR type)

3a — PAC CLI bump checks (nuget.json changed)

# Verify both packages have the same version
node -e "
const n = require('./nuget.json');
const vers = n.packages.map(p => p.version);
console.log('versions:', [...new Set(vers)].join(', '));
console.log(vers.every(v => v === vers[0]) ? 'OK: match' : 'MISMATCH');
" 2>&1

# Verify the version exists on nuget.org
curl -s "https://api.nuget.org/v3-flatcontainer/microsoft.powerapps.cli/index.json" \
  | node -e "const d=JSON.parse(require('fs').readFileSync('/dev/stdin','utf8')); \
    const v=require('./nuget.json').packages[0].version; \
    console.log(d.versions.includes(v)?'nuget: found':'nuget: NOT FOUND')" 2>&1

Request changes immediately if:

  • nuget.json packages have mismatched versions
  • Version does not exist on nuget.org
  • overview.md has no entry for the new version
  • {{NextReleaseVersion}} placeholder was removed from overview.md

3b — npm dependency checks (package.json changed)

Check the diff for:

  • No flat minimatch@^3.x override — causes infinite npm resolution loop
  • ajv override stays at ^6.x — v8 breaks ESLint
  • New overrides are at minimum required version (not over-pinned)
  • inBundle: true entries in package-lock.json changes are intentional (overrides can't reach them)
  • No new direct dependency that should be in bundleDependencies

3c — Release/stable branch checks (base == release/stable)

Release PRs must be version bumps only. Request changes immediately if:

  • Contains .ts logic changes (not just version string changes)
  • Adds new dependencies not present in the corresponding main PR
  • No corresponding merged main PR exists with the same changes

Verify the paired main PR exists:

gh search prs --repo microsoft/powerplatform-build-tools \
  --state merged --base main "<version-or-keyword>" 2>&1

Step 4 — Research context

Run in parallel to inform the review:

# Find similar past PRs (2-3 keywords from PR title)
gh search prs --repo microsoft/powerplatform-build-tools \
  --state merged --limit 8 "<keyword1> <keyword2>" 2>&1

# For top matches, read the body:
gh pr view <past-pr-number> --json title,body,mergedAt 2>&1

Also check memory/ado-knowledge.md for related ADO work items.

Skip ADO query for pure PAC CLI or dependency PRs — rarely adds value.


Step 5 — File-level review (feature/bug fix PRs, or any PR touching src/)

Fetch the full diff:

gh pr diff <PR_NUMBER> 2>&1

For each changed file apply:

| File pattern | What to check |

| ------------ | ------------- |

| src/tasks/*/index.ts | tl.getInput() used correctly; errors reach tl.setResult(TaskResult.Failed, ...); no pac args assembled here |

| src/tasks/*/task.json | Input names unchanged (renaming breaks customer pipelines); type correct; required set correctly |

| src/host/BuildToolsHost.ts | ALL 32 tasks affected — flag blast radius |

| src/params/auth/getCredentials.ts | All four auth types still work: UsernamePassword, SPN, ManagedIdentity, WorkloadIdentity |

| src/params/auth/getEnvironmentUrl.ts | 4-level fallback preserved: task input → pipeline variable → connection → default |

| extension/task-metadata.json | LIVE GUIDs must never change |

| extension/extension-manifest.json | Publisher and extension ID must not change |

| gulp/pack.mjs | tar imported via createRequire, not ESM import |

| test/unit-test/** | New behaviour is tested; mocks use rewiremock |

Security (every PR):

  • No secrets, tokens, or credentials committed
  • No --no-verify or commit hook bypasses

Architecture alignment:

  • Pipeline logic stays in build-tools; pac CLI arg construction stays in cli-wrapper
  • New tasks follow IIFE → isRunningOnAgent()main() → cli-wrapper pattern

Known failure patterns from knowledge base:

  • WhoAmI locale failure (ADO #4846644): flag any change near whoAmI or locale handling
  • AAD/OAuth authority (ADO #4863652): resolveCloudInstance() map must be preserved
  • PVA import failure (IcM 604312672): pac CLI version bumps should reference changelog

Step 6 — Post inline comments

HEAD_SHA=$(gh pr view <PR_NUMBER> --json headRefOid --jq .headRefOid)

gh api repos/microsoft/powerplatform-build-tools/pulls/<PR_NUMBER>/comments \
  --method POST \
  --field body="<comment>" \
  --field commit_id="$HEAD_SHA" \
  --field path="<file-path>" \
  --field line=<line-number> \
  --field side="RIGHT" 2>&1

Format: ⚠️ <risk> / 🚨 Breaking: <impact> / 💡 Suggestion: / ❓ <question>

Max 15 inline comments — consolidate minor points into the overall review body.


Step 7 — Post overall review and verdict

gh pr review <PR_NUMBER> --comment --body "$(cat <<'EOF'
## Review

**Reviewed by:** Claude Code (autonomous review agent)
**PR type:** <PAC CLI bump / npm dep update / feature / release branch>
**Similar PRs:** <titles + numbers, or "none">
**ADO context:** <relevant items, or "none">

### Breaking changes
<task.json, GUID, or interface changes — or "None detected">

### Security
<!-- Omit if no findings -->

### Architecture
<!-- Omit if no findings -->

### Dependencies
<!-- Omit if package files unchanged -->

### Suggestions
<!-- Omit if none -->

### Verdict
**✅ Approve** / **🔄 Request changes** / **💬 Comment** — <one line reason>
EOF
)" 2>&1

# Then execute the verdict:
gh pr review <PR_NUMBER> --approve 2>&1
# or
gh pr review <PR_NUMBER> --request-changes --body "<blocker>" 2>&1

Verdict decision table

| Condition | Verdict |

| --------- | ------- |

| LIVE GUID changed | Request changes — critical breaking |

| task.json input renamed | Request changes — breaks customer pipelines |

| Secret/credential in diff | Request changes — security |

| CI failing on non-functional-test step | Request changes |

| release/stable PR has logic changes | Request changes — version bumps only on release branch |

| release/stable PR missing paired main PR | Request changes |

| nuget.json package version mismatch | Request changes — CLI update incomplete |

| PAC CLI version not on nuget.org | Request changes — version doesn't exist |

| Only non-blocking suggestions | Approve with inline suggestions |

| PAC CLI bump verified clean | Approve |

| No findings | Approve |

| Intent unclear | Comment |

Never:

  • Approve a PR with a LIVE GUID change, renamed input, or committed secret
  • Block a PR because functional tests fail locally (expected — require live credentials)
  • Re-flag elliptic LOW vuln (known accepted risk, no patch exists)

How to use it

Copy the folder

Take microsoft/review from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
