code-review

name	code-review
description	Run all enabled review agents against target files. Use this whenever the user asks for a code review, wants feedback on their code, says "review my code", "check this before I PR", "what's wrong with this", "run the agents", or has just finished implementing a feature. Use proactively before commits and pull requests.

Code Review

Role: orchestrator. Route work to review agents; do not review code yourself. Pass each agent's tier alias (from its model: frontmatter) when dispatching — the PreToolUse hook hooks/agent-model-resolve.sh resolves it to the active snapshot per the Resolution Procedure in agents/orchestrator.md.

Output templates and JSON schemas: output-format.md. Example report: examples/sample-report.md.

Orchestrator constraints

1. Do not review code yourself. Delegate all semantic analysis to review agents.
2. Minimize context per agent. Pass only what each agent's Context needs field requires.
3. Route to the right model tier. Each agent's model: frontmatter declares its tier alias (haiku/sonnet/opus); the PreToolUse hook hooks/agent-model-resolve.sh resolves it to the active snapshot per agents/orchestrator.md → Resolution Procedure. Do not override the frontmatter value.
4. Run deterministic gates first. Lint, type-check, secret scan are cheaper than AI. Stop if they fail.
5. Return structured results. Aggregate agent JSON; do not add your own findings.
6. Be concise. Tables and JSON, no preambles, no filler.

Parse Arguments

Arguments: $ARGUMENTS

Flag	Behavior
--agent <name>	Run only the named agent (delegates to /review-agent)
--since <ref>	Review files changed since the ref (git diff --name-only <ref>...HEAD)
--path <dir>	Review only files in this directory
--all	Force full-repository review even when uncommitted changes exist
--json	Output aggregated JSON instead of prose (for CI integration)
--init-risks	Scaffold ACCEPTED-RISKS.md from templates/ACCEPTED-RISKS.md.tmpl if absent. Exits non-zero without overwriting if present. Schema: knowledge/accepted-risks-schema.md.
--force	Skip pre-flight gates and the documentation-only short-circuit (forces a full review of doc-only changes). Requires --reason "<text>" — logged to metrics/override-audit.jsonl.
--reason "<text>"	Override justification (required with --force)
--static-analysis / --no-static-analysis	Force on/off the static analysis pre-pass (Semgrep, ESLint, TypeScript, pylint). Auto-enabled when tools are detected.
--background	Drift review mode — review default branch for documentation, naming, and structural drift. Runs doc-review, arch-review, naming-review, structure-review only. Skips pre-flight gates.
(no flags)	Auto-scope: review uncommitted changes if any exist, otherwise full repository

Steps

1. Determine target files

Priority order:

1. --path <dir> — files in that directory (exclude node_modules, .git, dist, build, coverage)
2. --since <ref> — git diff --name-only <ref>...HEAD
3. --all — all source files
4. Auto-scope (no flags): run git diff --name-only + git diff --cached --name-only, combine and dedupe. If non-empty, review those files. If empty, review the full repository.

Scope validation (full-repo paths only):

File count	Action
≤200	Proceed
201–500	Warn: "Reviewing {N} files — consider --path to narrow scope." Proceed.
>500	Warn + confirm: "Reviewing {N} files is expensive. Continue?" Wait.

Documentation-only short-circuit. After the target set is known, classify each file. A file is documentation when it matches a doc type or path:

• extension .md, .mdx, .markdown, .rst, .txt, .adoc
• any path under a docs/ directory
• a root doc: README*, CHANGELOG*, CONTRIBUTING*, LICENSE*, NOTICE*, AUTHORS*, CODE_OF_CONDUCT*

…except functional Claude-config markdown, which is never documentation (it drives agent/skill/command behavior and must be reviewed): any path containing a .claude/ segment, or under agents/, skills/, prompts/, knowledge/, or templates/agents/. Treat CLAUDE.md and AGENTS.md as functional config too, not documentation.

If every target file is documentation, short-circuit:

1. Emit: Documentation-only changeset ({N} files) — skipping code review. Re-run with --force --reason "<text>" to review anyway.
2. If the review was auto-scoped to uncommitted changes, write the .review-passed gate file (per step 9) so the pre-commit hook allows the commit.
3. In --json mode, emit {"status": "skipped", "reason": "documentation-only", "files": [<list>]} instead.
4. Stop. Do not run pre-flight gates, static analysis, or any agent.

Bypass: the short-circuit does not apply with --force (with --reason), --agent <name>, or --background (drift review always inspects docs).

1b. Check for institutional context

If REVIEW-CONTEXT.md exists at the repo root, read it and pass its contents to every agent in step 4, prefixed with: "Institutional context provided for this review:". This file is optional.

1c. Probe for optional MCP tools

Tool	Check	Use
RoslynMCP	get_code_metrics / search_symbols available	C# metrics, compiler diagnostics
Code knowledge graph	list_repos available	Cross-repo dependency mapping
Documentation MCP	wiki/docs search available	Architecture docs
Semgrep	which semgrep	SAST context for security-review

Pass availability info to each agent so they can use enhanced tools or fall back to Glob/Grep/Read. Include in the final report per knowledge/review-template.md.

2. Pre-flight gates

Skip entirely if --background. If --force without --reason, halt:

ERROR: --force requires --reason "<justification>".

If --force with --reason, append an entry to metrics/override-audit.jsonl per the schema in output-format.md, then proceed to step 3.

Otherwise run these in sequence (stop on first failure):

1. Lint: npx eslint (or project lint command) on target files.
2. Type check: npx tsc --noEmit if tsconfig.json exists.
3. Secret scan: grep target files for (?i)(api[_-]?key|secret|password|token)\s*[:=]\s*['"][^'"]{8,}.
4. Semgrep SAST: semgrep scan --config auto --quiet --json on target files if installed. ERROR-severity → fail. WARNING-severity → continue, include in report. Save findings for security-review context.
5. Pipeline-red check: gh run list --branch $(git branch --show-current) --limit 1 --json conclusion -q '.[0].conclusion' if gh is available. If the last CI run failed, warn: "Pipeline is red. Fix CI before adding new code. Use --force to override."

Skip any gate silently if its tool is unavailable.

2b. Static analysis pre-pass

Skip if --no-static-analysis or --background.

Follow the detection, execution, and deduplication procedure in skills/static-analysis-integration/SKILL.md. Output is structured findings injected into agent context in step 4. This step does not gate execution — it collects context only.

If Semgrep already ran in the pre-flight gate, reuse those findings. Do not run Semgrep twice.

3. Determine enabled agents

If --background: run only doc-review, arch-review, naming-review, structure-review. Skip all others.

Otherwise enumerate review agents from agents/*.md (identified by a Model tier: field in body). All are enabled by default.

Language-agnostic agents always run regardless of tech stack: doc-review, arch-review, claude-setup-review, token-efficiency-review.

If review-config.json exists at the repo root, honor its per-agent "enabled": false flags.

4. Run each enabled agent

Spawn agents as parallel subagents in a single message using the Agent tool.

• File scope: pass only files matching each agent's declared scope. Skip the agent if no files match.
• Context payload (controlled by the agent's Context needs):
  • diff-only → diff output only (for auto-scope or --since only)
  • full-file → complete files
  • project-structure → full files + directory tree
  • When reviewing full repository (clean auto-scope, --all, or --path), always pass full files.
• Model: pass each agent's declared tier alias (haiku/sonnet/opus) from its model: frontmatter. The PreToolUse hook hooks/agent-model-resolve.sh resolves the tier to the active snapshot per agents/orchestrator.md → Resolution Procedure.
• Static analysis context: if step 2b produced findings, inject into every agent's prompt using the format in skills/static-analysis-integration/SKILL.md: "These issues were detected by static analysis. Do not re-report them. Focus on semantic concerns."
• Per-agent output: {"agentName": "<name>", "status": "pass|warn|fail", "issues": [], "summary": "..."} (full schema in output-format.md).

Wait for all agents to complete before aggregating.

5. Aggregate results

5a. Apply ACCEPTED-RISKS.md

If ACCEPTED-RISKS.md exists at the repo root, parse its rules: YAML frontmatter per knowledge/accepted-risks-schema.md. For each finding, check rules in declaration order; the first match suppresses and emits one audit entry:

SUPPRESSED: <file>:<line> [<rule_id>] by ACCEPTED-RISKS rule <rule.id>

• Expired rules become inert: stop suppressing, emit a WARN naming the rule and owner, list in an Expiry Report section.
• Rules with broad: true (wildcard rule_id or multi-file globs) emit an informational notice for auditor attention.
• Schema-invalid rules fail the run with a parse error naming the rule id.

Suppressed findings are removed from scoring, listed under "Suppressed by ACCEPTED-RISKS" in the report (grouped by rule id), and bypass the fix loop.

5b. Health scoring

Read knowledge/review-rubric.md for the formula. Compute the overall health score; security failures auto-escalate to 🔴.

Classify each issue by actionability:

Severity	Confidence	Actionable?
error or warning	high or medium	Yes — auto-apply
error or warning	none	No — report only (human judgment)
suggestion	any	No — report only

Actionable issues drive the fix loop.

6. Present findings and ask for direction

If zero actionable issues, skip to step 7.

Otherwise present the Review Findings prompt (template: output-format.md) and ask: "Fix these issues automatically, or save as report only?"

• "Fix" / "apply" / "yes" → step 6a
• "Report" / "no" / "don't fix" → step 7 (no code modified)

Exception — non-interactive mode: if running inside /build or /pr, skip this prompt and proceed to the fix loop. The caller owns the human gate (the orchestrator's Phase 3 approval for /build; the pre-PR confirmation for /pr).

6a. Review-fix loop

iteration = 1
MAX_ITERATIONS = 5

while actionable_issues > 0 AND iteration ≤ MAX_ITERATIONS:
    1. Apply fixes for all actionable issues (file-by-file, top-to-bottom by line)
    2. After each iteration's fixes, run the project's test suite.
       If tests fail, revert the last fix that broke them and mark the
       issue [auto-fix failed — human review required].
    3. Re-run only the agents that reported actionable issues, against only
       the modified files. Carry forward statuses of agents that passed.
    4. Re-aggregate. Reclassify remaining issues.
    5. iteration += 1

if iteration > MAX_ITERATIONS AND actionable_issues > 0:
    escalate to human with remaining issues

Exit conditions:

Condition	Action
Zero actionable issues	Exit → step 7
Iteration limit (5)	Exit → escalate
Same issues persist	Exit — not converging
Tests fail after fix and revert	Mark issue human-required; continue

Track each iteration for the report — template in output-format.md.

7. Generate report

Read knowledge/review-template.md for the structure.

If --json, emit the aggregated JSON object per the schema in output-format.md and stop.

Otherwise emit the prose summary using the Code Review Summary template in output-format.md. Append the iteration table.

8. Save correction prompts for remaining issues

For issues NOT auto-fixed (confidence: none, auto-fix failed, or suggestions), generate one correction prompt per issue using the Correction prompt schema in output-format.md. Save to corrections/. These can be addressed manually or via /apply-fixes.

9. Write pre-commit gate file

If the review was auto-scoped to uncommitted changes and the overall status is pass or warn, write .review-passed so the pre-commit hook allows the next commit. Use the shared gate-hash helper so the writer and the pre-commit hook compute the hash identically — it hashes the staged content (the cached patch), not just the file paths (#193), so any edit after review invalidates the gate:

bash ${CLAUDE_PLUGIN_ROOT}/hooks/lib/review-gate-hash.sh > .review-passed

Stage the exact changes you reviewed (git add them) before writing the gate, so the staged content the hook hashes matches what was reviewed. If git diff --cached is empty (you reviewed unstaged changes), stage them first — the gate binds to the staged patch by design.

If overall status is fail, do not write the gate file — the pre-commit hook will keep blocking until issues are resolved and the review re-run.
