Build Fix Skill

Fix build and compilation errors quickly with minimal code changes. Get the build green without refactoring.

When to Use

This skill activates when:

• User says "fix the build", "build is broken"

• TypeScript compilation fails

• the build command or type checker reports errors

• User requests "minimal fixes" for errors

What It Does

Delegates to the build-fixer agent (Sonnet model) to:

Collect Errors

• Run the project's type check command (e.g., tsc --noEmit , mypy , cargo check , go vet )

• Or run the project's build command to get build failures

• Categorize errors by type and severity

Fix Strategically

• Add type annotations where missing

• Add null checks where needed

• Fix import/export statements

• Resolve module resolution issues

• Fix linter errors blocking build

Minimal Diff Strategy

• NO refactoring of unrelated code

• NO architectural changes

• NO performance optimizations

• ONLY what's needed to make build pass

Verify

• Run the project's type check command after each fix

• Ensure no new errors introduced

• Stop when build passes

Agent Delegation

Task( subagent_type="oh-my-claudecode:build-fixer", model="sonnet", prompt="BUILD FIX TASK

Fix all build and TypeScript errors with minimal changes.

Requirements:

• Run tsc/build to collect errors
• Fix errors one at a time
• Verify each fix doesn't introduce new errors
• NO refactoring, NO architectural changes
• Stop when build passes

Output: Build error resolution report with:

• List of errors fixed
• Lines changed per fix
• Final build status" )

Stop Conditions

The build-fixer agent stops when:

• Type check command exits with code 0

• Build command completes successfully

• No new errors introduced

Output Format

BUILD FIX REPORT

Errors Fixed: 12 Files Modified: 8 Lines Changed: 47

Fixes Applied:

1. src/utils/validation.ts:15 - Added return type annotation
2. src/components/Header.tsx:42 - Added null check for props.user
3. src/api/client.ts:89 - Fixed import path for axios ...

Final Build Status: ✓ PASSING Verification: [type check command] (exit code 0)

Best Practices

• One fix at a time - Easier to verify and debug

• Minimal changes - Don't refactor while fixing

• Document why - Comment non-obvious fixes

• Test after - Ensure tests still pass

Use with Other Skills

Combine with other skills for comprehensive fixing:

With Ultrawork:

/ultrawork fix all build errors

Spawns multiple build-fixer agents in parallel for different files.

With Ralph:

/ralph fix the build

Keeps trying until build passes, even if it takes multiple iterations.

With Pipeline:

/pipeline debug "build is failing"

Uses: explore → architect → build-fixer workflow.
