Build Fix Mode

Recommended model tier: balanced (sonnet) - this skill performs straightforward operations

Rapidly fix all build, type, and lint errors with minimal changes.

Prerequisites

Before starting, ensure you have:

•Access to the project root directory
•Build tools installed (npm, tsc, etc.)

Workflow

Step 1: Capture All Errors

Run all checks and capture output:

bash

# Run in sequence, capture all output
npm run build 2>&1 | head -100
npm run lint 2>&1 | head -100
npx tsc --noEmit 2>&1 | head -100

If commands fail to run:

•Check package.json for available scripts
•Try npm install if dependencies are missing
•Use npm ci for clean install if lock file exists

Step 2: Categorize Errors by Priority

Process errors in this order:

•Type errors (highest priority) - Fix TypeScript/type issues first
•Build errors - Compilation failures
•Lint errors - ESLint, Prettier, etc.
•Warnings - Address only if trivial

Group similar errors:

•Missing imports
•Type mismatches
•Unused variables
•Formatting issues

Step 3: Search for Context

Use MCP tools to find definitions and patterns:

code

# Find type definitions
mcp__plugin_aide_aide__code_search query="InterfaceName" kind="interface"

# Find function signatures
mcp__plugin_aide_aide__code_search query="functionName" kind="function"

# Get symbols in a file
mcp__plugin_aide_aide__code_symbols file="path/to/file.ts"

# Check project conventions
mcp__plugin_aide_aide__decision_get topic="coding-style"

Step 4: Apply Fixes Systematically

Fix in batches by category:

•All missing imports together - Add import statements
•All type annotations together - Add/fix type declarations
•All unused variables together - Remove or prefix with _

Step 5: Verify After Each Batch

bash

# Run full verification
npm run build && npm run lint && npx tsc --noEmit

Verification criteria:

•Exit code 0 for all commands
•No error output
•Warnings are acceptable if not introduced by changes

Step 6: Final Verification

bash

# Run tests to ensure fixes didn't break functionality
npm test

Failure Handling

Failure	Action
`npm run build` fails to start	Run `npm install` first
Circular dependency error	Check import structure, may need refactoring
Type error in third-party lib	Check @types package version, update if needed
Cannot resolve module	Check tsconfig.json paths, baseUrl settings
ESLint config error	Check .eslintrc, ensure plugins installed
Fix introduces new errors	Revert and try alternative approach

Rules

•Minimal changes - Fix only what's broken
•No refactoring - Don't improve "while you're there"
•No new features - Just fix errors
•Match style - Follow existing patterns exactly
•One batch at a time - Verify between batches

Common Fixes Reference

Error	Fix
Cannot find module	Add import statement
Type 'X' not assignable	Add type annotation or use type assertion
'X' is declared but never used	Remove or prefix with `_`
Missing return type	Add explicit return type
Unexpected any	Add proper type annotation
Property does not exist	Check interface, add property or fix typo
Argument of type X not assignable	Check function signature, cast if needed
