fix

---

name: fix description: This skill should be used when the user asks to "fix the issues", "apply the fixes", "fix what the review found", "auto-fix bugs", or wants to execute fixes for issues identified by a prior code review. Spawns @engineer subagents to fix issues in parallel.

Execute fixes for code issues identified by a prior review. This skill assumes a review has already been run and its output is available in the conversation.

Prerequisites

This skill expects review output in the conversation containing:

• Issues with file paths and line numbers
• Severity levels (critical/warning/suggestion)
• Issue descriptions with realistic scenarios
• Suggested fixes (if provided)

If no review output is found, prompt the user to run a review first.

Execution

1. Parse Review Output

Extract fixable issues from the prior review output:

CopyIssues to fix:
- [critical] path/file.ts:123 - Issue description
- [warning] path/file.ts:456 - Issue description

Filter by severity:

• Default: Critical + Warning
• Skip suggestions unless explicitly requested

2. Group by File

Group issues by file to minimize context switching:

Copypath/file1.ts:
  - Line 123: [critical] Issue A
  - Line 456: [warning] Issue B

path/file2.ts:
  - Line 78: [warning] Issue C

3. Spawn @engineer Agents

For each file with issues, spawn an @engineer subagent with:

CopyFix the following issues in [filepath]:

1. Line [N]: [severity] [issue description]
   Suggested fix: [if available]

Rules:
- Make minimal changes - only fix the reported issues
- Don't refactor or improve adjacent code
- Don't add extra error handling "while you're there"
- Preserve all existing behavior except the bug
- Read the full file first to understand context

Spawn agents in parallel for independent files.

4. Verification

After all agents complete:

Copy# Syntax check (TypeScript projects)
npx tsc --noEmit 2>&1 | head -50

# Run tests if available
npm test 2>&1 | head -100

# Show changes
git diff --stat

5. Simplification

After fixes are verified, run code-simplifier on modified files:

CopyTask: code-simplifier:code-simplifier
Prompt: Simplify and refine the code that was just fixed. Focus on recently modified files only.

This ensures fixes don't introduce unnecessary complexity.

Output Format

Fixes Applied

Issues Requiring Manual Intervention

List any issues that couldn't be auto-fixed:

• [file:line] Reason why manual fix is needed

Verification

• Syntax: Pass / Fail
• Tests: Pass / Fail / Skipped
• Files modified: N

Safety

• Never fix suggestions automatically
• Never modify security-critical code without clear fix path
• Stop and report if fixes cause test failures
