refactor(skills): consolidate code verification skills into one (#4854)
* chore: release v0.7.0 (2026.4.3) 168 merged PRs, 223 commits, 46 resolved issues, 40+ contributors. Highlights: pluggable memory providers, credential pools, Camofox browser, inline diff previews, API server session continuity, ACP MCP registration, gateway hardening, secret exfiltration blocking. * refactor(skills): consolidate code-review + verify-code-changes into requesting-code-review Merge the passive code-review checklist and the automated verification pipeline (from PR #4459 by @MorAlekss) into a single requesting-code-review skill. This eliminates model confusion between three overlapping skills. Now includes: - Static security scan (grep on diff lines) - Baseline-aware quality gates (only flag NEW failures) - Multi-language tool detection (Python, Node, Rust, Go) - Independent reviewer subagent with fail-closed JSON verdict - Auto-fix loop with separate fixer agent (max 2 attempts) - Git checkpoint and [verified] commit convention Deletes: skills/software-development/code-review/ (absorbed) Closes: #406 (independent code verification)

# Code Review Skill
|
||||
|
||||
Use this skill when reviewing code changes, pull requests, or auditing existing code.
|
||||
|
||||
## Review Checklist
|
||||
|
||||
### 1. Security First
|
||||
- [ ] No hardcoded secrets, API keys, or credentials
|
||||
- [ ] Input validation on all user-provided data
|
||||
- [ ] SQL queries use parameterized statements (no string concatenation)
|
||||
- [ ] File operations validate paths (no path traversal)
|
||||
- [ ] Authentication/authorization checks present where needed
|
||||
|
||||
### 2. Error Handling
|
||||
- [ ] All external calls (API, DB, file) have try/catch
|
||||
- [ ] Errors are logged with context (but no sensitive data)
|
||||
- [ ] User-facing errors are helpful but don't leak internals
|
||||
- [ ] Resources are cleaned up in finally blocks or context managers
|
||||
|
||||
### 3. Code Quality
|
||||
- [ ] Functions do one thing and are reasonably sized (<50 lines ideal)
|
||||
- [ ] Variable names are descriptive (no single letters except loops)
|
||||
- [ ] No commented-out code left behind
|
||||
- [ ] Complex logic has explanatory comments
|
||||
- [ ] No duplicate code (DRY principle)
|
||||
|
||||
### 4. Testing Considerations
|
||||
- [ ] Edge cases handled (empty inputs, nulls, boundaries)
|
||||
- [ ] Happy path and error paths both work
|
||||
- [ ] New code has corresponding tests (if test suite exists)
|
||||
|
||||
## Review Response Format
|
||||
|
||||
When providing review feedback, structure it as:
|
||||
|
||||
```
|
||||
## Summary
|
||||
[1-2 sentence overall assessment]
|
||||
|
||||
## Critical Issues (Must Fix)
|
||||
- Issue 1: [description + suggested fix]
|
||||
- Issue 2: ...
|
||||
|
||||
## Suggestions (Nice to Have)
|
||||
- Suggestion 1: [description]
|
||||
|

|
||||
|
||||
## Common Patterns to Flag
|
||||
|
||||
### Python
|
||||
```python
|
||||
# Bad: SQL injection risk
|
||||
cursor.execute(f"SELECT * FROM users WHERE id = {user_id}")
|
||||
|
||||
# Good: Parameterized query
|
||||
cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))
|
||||
```
|
||||
|
||||
### JavaScript
|
||||
```javascript
|
||||
// Bad: XSS risk
|
||||
element.innerHTML = userInput;
|
||||
|
||||
// Good: Safe text content
|
||||
element.textContent = userInput;
|
||||
```
|
||||
|
||||
## Tone Guidelines
|
||||
|
||||
- Be constructive, not critical
|
||||
- Explain *why* something is an issue, not just *what*
|
||||
- Offer solutions, not just problems
|
||||
- Acknowledge good patterns you see

# Requesting Code Review
|
||||
# Pre-Commit Code Verification
|
||||
|
||||
## Overview
|
||||
Automated verification pipeline before code lands. Static scans, baseline-aware
|
||||
quality gates, an independent reviewer subagent, and an auto-fix loop.
|
||||
|
||||
Dispatch a reviewer subagent to catch issues before they cascade. Review early, review often.
|
||||
**Core principle:** No agent should verify its own work. Fresh context finds what you miss.
|
||||
|
||||
**Core principle:** Fresh perspective finds issues you'll miss.
|
||||
## When to Use
|
||||
|
||||
## When to Request Review
|
||||
- After implementing a feature or bug fix, before `git commit` or `git push`
|
||||
- When user says "commit", "push", "ship", "done", "verify", or "review before merge"
|
||||
- After completing a task with 2+ file edits in a git repo
|
||||
- After each task in subagent-driven-development (the two-stage review)
|
||||
|
||||
**Mandatory:**
|
||||
- After each task in subagent-driven development
|
||||
- After completing a major feature
|
||||
- Before merge to main
|
||||
- After bug fixes
|
||||
**Skip for:** documentation-only changes, pure config tweaks, or when user says "skip verification".
|
||||
|
||||
**Optional but valuable:**
|
||||
- When stuck (fresh perspective)
|
||||
- Before refactoring (baseline check)
|
||||
- After complex logic implementation
|
||||
- When touching critical code (auth, payments, data)
|
||||
**This skill vs github-code-review:** This skill verifies YOUR changes before committing.
|
||||
`github-code-review` reviews OTHER people's PRs on GitHub with inline comments.
|
||||
|
||||
**Never skip because:**
|
||||
- "It's simple" — simple bugs compound
|
||||
- "I'm in a hurry" — reviews save time
|
||||
- "I tested it" — you have blind spots
|
||||
|
||||
## Review Process
|
||||
|
||||
### Step 1: Self-Review First
|
||||
|
||||
Before dispatching a reviewer, check yourself:
|
||||
|
||||
- [ ] Code follows project conventions
|
||||
- [ ] All tests pass
|
||||
- [ ] No debug print statements left
|
||||
- [ ] No hardcoded secrets or credentials
|
||||
- [ ] Error handling in place
|
||||
- [ ] Commit messages are clear
|
||||
## Step 1 — Get the diff
|
||||
|
||||
```bash
|
||||
# Run full test suite
|
||||
pytest tests/ -q
|
||||
|
||||
# Check for debug code
|
||||
search_files("print(", path="src/", file_glob="*.py")
|
||||
search_files("console.log", path="src/", file_glob="*.js")
|
||||
|
||||
# Check for TODOs
|
||||
search_files("TODO|FIXME|HACK", path="src/")
|
||||
git diff --cached
|
||||
```
|
||||
|
||||
### Step 2: Gather Context
|
||||
If empty, try `git diff` then `git diff HEAD~1 HEAD`.
|
||||
|
||||
If `git diff --cached` is empty but `git diff` shows changes, tell the user to
|
||||
`git add <files>` first. If still empty, run `git status` — nothing to verify.
|
||||
|
||||
If the diff exceeds 15,000 characters, split by file:
|
||||
```bash
|
||||
git diff --name-only
|
||||
git diff HEAD -- specific_file.py
|
||||
```
|
||||
|
||||
## Step 2 — Static security scan
|
||||
|
||||
Scan added lines only. Any match is a security concern fed into Step 5.
|
||||
|
||||
```bash
|
||||
# Changed files
|
||||
git diff --name-only HEAD~1
|
||||
# Hardcoded secrets
|
||||
git diff --cached | grep "^+" | grep -iE "(api_key|secret|password|token|passwd)\s*=\s*['\"][^'\"]{6,}['\"]"
|
||||
|
||||
# Diff summary
|
||||
git diff --stat HEAD~1
|
||||
# Shell injection
|
||||
git diff --cached | grep "^+" | grep -E "os\.system\(|subprocess.*shell=True"
|
||||
|
||||
# Recent commits
|
||||
git log --oneline -5
|
||||
# Dangerous eval/exec
|
||||
git diff --cached | grep "^+" | grep -E "\beval\(|\bexec\("
|
||||
|
||||
# Unsafe deserialization
|
||||
git diff --cached | grep "^+" | grep -E "pickle\.loads?\("
|
||||
|
||||
# SQL injection (string formatting in queries)
|
||||
git diff --cached | grep "^+" | grep -E "execute\(f\"|\.format\(.*SELECT|\.format\(.*INSERT"
|
||||
```
|
||||
|
||||
### Step 3: Dispatch Reviewer Subagent
|
||||
## Step 3 — Baseline tests and linting
|
||||
|
||||
Use `delegate_task` to dispatch a focused reviewer:
|
||||
Detect the project language and run the appropriate tools. Capture the failure
|
||||
count BEFORE your changes as **baseline_failures** (stash changes, run, pop).
|
||||
Only NEW failures introduced by your changes block the commit.
|
||||
|
||||
**Test frameworks** (auto-detect by project files):
|
||||
```bash
|
||||
# Python (pytest)
|
||||
python -m pytest --tb=no -q 2>&1 | tail -5
|
||||
|
||||
# Node (npm test)
|
||||
npm test -- --passWithNoTests 2>&1 | tail -5
|
||||
|
||||
# Rust
|
||||
cargo test 2>&1 | tail -5
|
||||
|
||||
# Go
|
||||
go test ./... 2>&1 | tail -5
|
||||
```
|
||||
|
||||
**Linting and type checking** (run only if installed):
|
||||
```bash
|
||||
# Python
|
||||
which ruff && ruff check . 2>&1 | tail -10
|
||||
which mypy && mypy . --ignore-missing-imports 2>&1 | tail -10
|
||||
|
||||
# Node
|
||||
which npx && npx eslint . 2>&1 | tail -10
|
||||
which npx && npx tsc --noEmit 2>&1 | tail -10
|
||||
|
||||
# Rust
|
||||
cargo clippy -- -D warnings 2>&1 | tail -10
|
||||
|
||||
# Go
|
||||
which go && go vet ./... 2>&1 | tail -10
|
||||
```
|
||||
|
||||
**Baseline comparison:** If baseline was clean and your changes introduce failures,
|
||||
that's a regression. If baseline already had failures, only count NEW ones.
|
||||
|
||||
## Step 4 — Self-review checklist
|
||||
|
||||
Quick scan before dispatching the reviewer:
|
||||
|
||||
- [ ] No hardcoded secrets, API keys, or credentials
|
||||
- [ ] Input validation on user-provided data
|
||||
- [ ] SQL queries use parameterized statements
|
||||
- [ ] File operations validate paths (no traversal)
|
||||
- [ ] External calls have error handling (try/catch)
|
||||
- [ ] No debug print/console.log left behind
|
||||
- [ ] No commented-out code
|
||||
- [ ] New code has tests (if test suite exists)
|
||||
|
||||
## Step 5 — Independent reviewer subagent
|
||||
|
||||
Call `delegate_task` directly — it is NOT available inside execute_code or scripts.
|
||||
|
||||
The reviewer gets ONLY the diff and static scan results. No shared context with
|
||||
the implementer. Fail-closed: unparseable response = fail.
|
||||
|
||||
```python
|
||||
delegate_task(
|
||||
goal="Review implementation for correctness and quality",
|
||||
context="""
|
||||
WHAT WAS IMPLEMENTED:
|
||||
[Brief description of the feature/fix]
|
||||
goal="""You are an independent code reviewer. You have no context about how
|
||||
these changes were made. Review the git diff and return ONLY valid JSON.
|
||||
|
||||
ORIGINAL REQUIREMENTS:
|
||||
[From plan, issue, or user request]
|
||||
FAIL-CLOSED RULES:
|
||||
- security_concerns non-empty -> passed must be false
|
||||
- logic_errors non-empty -> passed must be false
|
||||
- Cannot parse diff -> passed must be false
|
||||
- Only set passed=true when BOTH lists are empty
|
||||
|
||||
FILES CHANGED:
|
||||
- src/models/user.py (added User class)
|
||||
- src/auth/login.py (added login endpoint)
|
||||
- tests/test_auth.py (added 8 tests)
|
||||
SECURITY (auto-FAIL): hardcoded secrets, backdoors, data exfiltration,
|
||||
shell injection, SQL injection, path traversal, eval()/exec() with user input,
|
||||
pickle.loads(), obfuscated commands.
|
||||
|
||||
REVIEW CHECKLIST:
|
||||
- [ ] Correctness: Does it do what it should?
|
||||
- [ ] Edge cases: Are they handled?
|
||||
- [ ] Error handling: Is it adequate?
|
||||
- [ ] Code quality: Clear names, good structure?
|
||||
- [ ] Test coverage: Are tests meaningful?
|
||||
- [ ] Security: Any vulnerabilities?
|
||||
- [ ] Performance: Any obvious issues?
|
||||
LOGIC ERRORS (auto-FAIL): wrong conditional logic, missing error handling for
|
||||
I/O/network/DB, off-by-one errors, race conditions, code contradicts intent.

### Step 4: Act on Feedback
|
||||
## Step 6 — Evaluate results
|
||||
|
||||
**Critical Issues (block merge):**
|
||||
- Security vulnerabilities
|
||||
- Broken functionality
|
||||
- Data loss risk
|
||||
- Test failures
|
||||
- **Action:** Fix immediately before proceeding
|
||||
Combine results from Steps 2, 3, and 5.
|
||||
|
||||
**Important Issues (should fix):**
|
||||
- Missing edge case handling
|
||||
- Poor error messages
|
||||
- Unclear code
|
||||
- Missing tests
|
||||
- **Action:** Fix before merge if possible
|
||||
**All passed:** Proceed to Step 8 (commit).
|
||||
|
||||
**Minor Issues (nice to have):**
|
||||
- Style preferences
|
||||
- Refactoring suggestions
|
||||
- Documentation improvements
|
||||
- **Action:** Note for later or quick fix
|
||||
**Any failures:** Report what failed, then proceed to Step 7 (auto-fix).
|
||||
|
||||
**If reviewer is wrong:**
|
||||
- Push back with technical reasoning
|
||||
- Show code/tests that prove it works
|
||||
- Request clarification
|
||||
```
|
||||
VERIFICATION FAILED
|
||||
|
||||
## Review Dimensions
|
||||
Security issues: [list from static scan + reviewer]
|
||||
Logic errors: [list from reviewer]
|
||||
Regressions: [new test failures vs baseline]
|
||||
New lint errors: [details]
|
||||
Suggestions (non-blocking): [list]
|
||||
```
|
||||
|
||||
### Correctness
|
||||
- Does it implement the requirements?
|
||||
- Are there logic errors?
|
||||
- Do edge cases work?
|
||||
- Are there race conditions?
|
||||
## Step 7 — Auto-fix loop
|
||||
|
||||
### Code Quality
|
||||
- Is code readable?
|
||||
- Are names clear and descriptive?
|
||||
- Is it too complex? (Functions >20 lines = smell)
|
||||
- Is there duplication?
|
||||
**Maximum 2 fix-and-reverify cycles.**
|
||||
|
||||
### Testing
|
||||
- Are there meaningful tests?
|
||||
- Do they cover edge cases?
|
||||
- Do they test behavior, not implementation?
|
||||
- Do all tests pass?
|
||||
Spawn a THIRD agent context — not you (the implementer), not the reviewer.
|
||||
It fixes ONLY the reported issues:
|
||||
|
||||
### Security
|
||||
- Any injection vulnerabilities?
|
||||
- Proper input validation?
|
||||
- Secrets handled correctly?
|
||||
- Access control in place?
|
||||
|
||||
### Performance
|
||||
- Any N+1 queries?
|
||||
- Unnecessary computation in loops?
|
||||
- Memory leaks?
|
||||
- Missing caching opportunities?

- [What was done well]
|

## Reference: Common Patterns to Flag
|
||||
|
||||
### Python
|
||||
```python
|
||||
# Bad: SQL injection
|
||||
cursor.execute(f"SELECT * FROM users WHERE id = {user_id}")
|
||||
# Good: parameterized
|
||||
cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))
|
||||
|
||||
# Bad: shell injection
|
||||
os.system(f"ls {user_input}")
|
||||
# Good: safe subprocess
|
||||
subprocess.run(["ls", user_input], check=True)
|
||||
```
|
||||
|
||||
### JavaScript
|
||||
```javascript
|
||||
// Bad: XSS
|
||||
element.innerHTML = userInput;
|
||||
// Good: safe
|
||||
element.textContent = userInput;
|
||||
```
|
||||
|
||||
## Integration with Other Skills
|
||||
|
||||
### With subagent-driven-development
|
||||
**subagent-driven-development:** Run this after EACH task as the quality gate.
|
||||
The two-stage review (spec compliance + code quality) uses this pipeline.
|
||||
|
||||
Review after EACH task — this is the two-stage review:
|
||||
1. Spec compliance review (does it match the plan?)
|

2. Code quality review (is it well-built?)
|
||||
3. Fix issues from either review
|
||||
4. Proceed to next task only when both approve
|
||||
**test-driven-development:** This pipeline verifies TDD discipline was followed —
|
||||
tests exist, tests pass, no regressions.
|
||||
|
||||
### With test-driven-development
|
||||
**writing-plans:** Validates implementation matches the plan requirements.
|
||||
|
||||
Review verifies:
|
||||
- Tests were written first (RED-GREEN-REFACTOR followed?)
|
||||
- Tests are meaningful (not just asserting True)?
|
||||
- Edge cases covered?
|
||||
- All tests pass?
|
||||
## Pitfalls
|
||||
|
||||
### With writing-plans
|
||||
|
||||
Review validates:
|
||||
- Implementation matches the plan?
|
||||
- All tasks completed?
|
||||
- Quality standards met?
|
||||
|
||||
## Red Flags
|
||||
|
||||
**Never:**
|
||||
- Skip review because "it's simple"
|
||||
- Ignore Critical issues
|
||||
- Proceed with unfixed Important issues
|
||||
- Argue with valid technical feedback without evidence
|
||||
|
||||
## Quality Gates
|
||||
|
||||
**Must pass before merge:**
|
||||
- [ ] No critical issues
|
||||
- [ ] All tests pass
|
||||
- [ ] Review verdict: APPROVE
|
||||
- [ ] Requirements met
|
||||
|
||||
**Should pass before merge:**
|
||||
- [ ] No important issues
|
||||
- [ ] Documentation updated
|
||||
- [ ] Performance acceptable
|
||||
|
||||
## Remember
|
||||
|
||||
```
|
||||
Review early
|
||||
Review often
|
||||
Be specific
|
||||
Fix critical issues first
|
||||
Quality over speed
|
||||
```
|
||||
|
||||
**A good review catches what you missed.**
|
||||
- **Empty diff** — check `git status`, tell user nothing to verify
|
||||
- **Not a git repo** — skip and tell user
|
||||
- **Large diff (>15k chars)** — split by file, review each separately
|
||||
- **delegate_task returns non-JSON** — retry once with stricter prompt, then treat as FAIL
|
||||
- **False positives** — if reviewer flags something intentional, note it in fix prompt
|
||||
- **No test framework found** — skip regression check, reviewer verdict still runs
|
||||
- **Lint tools not installed** — skip that check silently, don't fail
|
||||
- **Auto-fix introduces new issues** — counts as a new failure, cycle continues
