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. This skill routes work — it does not review code itself.

You have been invoked with the /code-review skill. Run all enabled review agents and produce a summary.

For output format details, see output-format.md. For an example report, see examples/sample-report.md.

Orchestrator constraints

Follow these constraints from the Minimum CD agent configuration pattern:

1. Do not review code yourself. Delegate all semantic analysis to review agents.
2. Minimize context passed to agents. Each agent receives only what its Context needs field requires.
3. Route to the right model tier. Each agent declares its tier — pass it through when spawning subagents.
4. Run deterministic gates first. Standard tooling (lint, type-check, secret scan) is cheaper than AI review. Do not invoke agents if gates fail.
5. Return structured results. Aggregate agent JSON into a summary — do not add your own findings.
6. Be concise. Use tables, JSON, and short sentences. No preambles, no filler, no restating the task. Every output token costs money.

Parse Arguments

Arguments: $ARGUMENTS

• --agent <name>: Run only the named agent (delegates to /review-agent)
• --changed: Review only uncommitted changes (git diff --name-only + git diff --cached --name-only)
• --since <ref>: Review files changed since a git ref (git diff --name-only <ref>...HEAD)
• --path <dir>: Target directory (default: current working directory)
• --json: Output aggregated JSON instead of prose summary (for CI integration)
• --force: Skip pre-flight gates and run agents even if deterministic checks fail
• No arguments: review all files in the target directory

Progress tracking

Copy this checklist and track progress:

- [ ] Target files determined
- [ ] Pre-flight gates passed
- [ ] Agents loaded and filtered
- [ ] All agents executed
- [ ] Results aggregated
- [ ] Report generated
- [ ] Correction prompts saved (if requested)

Steps

1. Determine target files

Based on arguments, build a file list:

• --changed: run git diff --name-only and git diff --cached --name-only, combine and deduplicate
• --since <ref>: run git diff --name-only <ref>...HEAD
• Default: glob all source files in the target path (exclude node_modules, .git, dist, build, coverage)

2. Pre-flight gates (fail fast, fail cheap)

Run deterministic checks before spending tokens on AI agents. Skip this step if --force is passed.

Sequence (stop on first failure unless --force):

1. Lint: Run npx eslint (or project lint command from package.json) on target files. If lint fails, report errors and stop.
2. Type check: Run npx tsc --noEmit if a tsconfig.json exists. If type errors exist, report and stop.
3. Secret scan: Grep target files for common secret patterns ((?i)(api[_-]?key|secret|password|token)\s*[:=]\s*['"][^'"]{8,}). If found, report and stop.
4. Semgrep SAST: Run semgrep scan --config auto --quiet --json on target files if semgrep is installed. ERROR-severity findings → gate fails (stop unless --force). WARNING-severity findings → include in report but don't stop. Skip silently if semgrep is not installed. Save findings to pass as context to security-review agent in step 4.
5. Pipeline-red check: Run git log --oneline -1 and check if there's a failing CI status on the current branch (run 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 — existing tests are failing. Fix CI before adding new code. Use --force to override."

If any gate fails and --force is not set, output the failure details and stop. Do not run agents.

If a tool is not available (e.g., no eslint, no tsconfig, no gh), skip that gate silently.

3. Determine enabled agents

List all agent files in agents/*.md. All agents are enabled by default.

If a review-config.json exists in the project root, read it. It can disable specific agents ("enabled": false). This file is optional and project-local — it is not part of the toolkit.

4. Run each enabled agent

For each enabled agent, spawn it as a parallel subagent using the Agent tool. Each agent runs in isolation against its matching files.

File scope: Each agent definition declares its own file scope (e.g., js-fp-review says "JavaScript and TypeScript files only"). Respect these scope declarations — only pass matching files, and skip the agent entirely if no target files match.

Context needs: Each agent declares a Context needs field. When using --changed or --since:

• diff-only: Pass only the diff output, not full files. More token-efficient.
• full-file: Pass full file contents for files in the target list.
• project-structure: Pass full files plus directory tree context.

When not using --changed/--since, always pass full files regardless of context needs.

Model tier: Each agent declares a Model tier field (small, mid, frontier). When spawning subagents, pass the model parameter:

• small → use model: "haiku" for the Agent tool
• mid → use model: "sonnet" for the Agent tool
• frontier → use default model (no model parameter needed)

Semgrep context: If semgrep findings were collected in gate 4, pass them as additional context to the security-review agent prompt. This lets the agent assess exploitability and focus AI analysis on issues semgrep cannot detect.

Parallelism: Launch all agents concurrently using multiple Agent tool calls in a single message. Wait for all to complete before aggregating.

Produce a JSON result per agent:

{"agentName": "<name>", "status": "pass|warn|fail", "issues": [], "summary": "..."}

5. Aggregate and report

If --json flag is set, output a single aggregated JSON object and stop:

{
  "overall": "pass|warn|fail",
  "timestamp": "<ISO 8601>",
  "targetFiles": 42,
  "preFlightPassed": true,
  "agents": [
    {"agentName": "test-review", "status": "pass", "issues": [], "summary": "..."},
    {"agentName": "security-review", "status": "fail", "issues": [], "summary": "..."}
  ]
        
   

Otherwise, produce a summary table:

# Code Review Summary

| Agent              | Status | Issues | Model Tier |
|--------------------|--------|--------|------------|
| test-review        | PASS   | 0      | mid        |
| structure-review   | WARN   | 2      | mid        |
| ...                | ...    | ...    | ...        |

Overall: WARN (N agents passed, N warned, N failed)
Total issues: N (N errors, N warnings, N suggestions)

Then list all issues grouped by file, sorted by severity (errors first).

6. Generate correction prompts

For each issue, generate a correction prompt:

{
  "priority": "high|medium|low",
  "category": "<agent-name>",
  "instruction": "Fix: <message> (Suggested: <suggestedFix>)",
  "context": "Line <line> in <file>",
  "affectedFiles": ["<file>"]
}

Severity mapping: error→high, warning→medium, suggestion→low.

If the user requests it, save prompts as individual JSON files in a corrections/ directory.
