Build Resolver

Purpose

Get a broken build passing with the absolute minimum changes. No refactoring, no architecture changes, no improvements — just fix what's broken and verify.

This skill is designed to run as an isolated agent with its own context window, so it can focus entirely on build errors without polluting the main conversation.

Use this when:

• tsc --noEmit reports errors after edits
• npm run build / next build fails
• CI pipeline breaks on type errors
• You need a quick fix without understanding the full context

Key Concepts

Minimal-Diff Philosophy

The build-resolver follows one rule: smallest possible change that makes the build green.

DO	DON'T
Add type annotations	Refactor code structure
Add null checks (?., ??)	Rename variables
Fix import paths	Add new features
Add missing interface fields	Change business logic
Cast types when safe	"Improve" existing code
Add @ts-expect-error as last resort	Add comments or docs

Common Error → Fix Map

Error Pattern	Fix
implicitly has type 'any'	Add explicit type annotation
possibly 'undefined'	Add optional chaining ?. or nullish coalescing ??
Property 'X' does not exist on type 'Y'	Add to interface or use type assertion
Cannot find module 'X'	Fix import path or install package
Type 'X' is not assignable to type 'Y'	Narrow type or add assertion
Argument of type 'X' is not assignable	Convert type at call site
