Affaan Mustafa 733295b44e docs: enhance 5 thin commands and add Rust API example
Commands enhanced with multi-language support, error recovery strategies,
and structured step-by-step workflows:
- build-fix: build system detection table, fix loop, recovery strategies
- test-coverage: framework detection, test generation rules, before/after report
- refactor-clean: safety tiers (SAFE/CAUTION/DANGER), multi-language tools
- update-codemaps: codemap format spec, diff detection, metadata headers
- update-docs: source-of-truth mapping, staleness checks, generated markers

New example:
- rust-api-CLAUDE.md: Axum + SQLx + PostgreSQL with layered architecture,
  thiserror patterns, compile-time SQL verification, integration test examples

Build and Fix

Incrementally fix build and type errors with minimal, safe changes.

Step 1: Detect Build System

Identify the project's build tool and run the build:

Indicator Build Command
package.json with build script npm run build or pnpm build
tsconfig.json (TypeScript only) npx tsc --noEmit
Cargo.toml cargo build 2>&1
pom.xml mvn compile
build.gradle ./gradlew compileJava
go.mod go build ./...
pyproject.toml python -m py_compile or mypy .

Step 2: Parse and Group Errors

  1. Run the build command and capture stderr
  2. Group errors by file path
  3. Sort by dependency order (fix imports/types before logic errors)
  4. Count total errors for progress tracking

Step 3: Fix Loop (One Error at a Time)

For each error:

  1. Read the file — Use Read tool to see error context (10 lines around the error)
  2. Diagnose — Identify root cause (missing import, wrong type, syntax error)
  3. Fix minimally — Use Edit tool for the smallest change that resolves the error
  4. Re-run build — Verify the error is gone and no new errors introduced
  5. Move to next — Continue with remaining errors

Step 4: Guardrails

Stop and ask the user if:

  • A fix introduces more errors than it resolves
  • The same error persists after 3 attempts (likely a deeper issue)
  • The fix requires architectural changes (not just a build fix)
  • Build errors stem from missing dependencies (need npm install, cargo add, etc.)

Step 5: Summary

Show results:

  • Errors fixed (with file paths)
  • Errors remaining (if any)
  • New errors introduced (should be zero)
  • Suggested next steps for unresolved issues

Recovery Strategies

Situation Action
Missing module/import Check if package is installed; suggest install command
Type mismatch Read both type definitions; fix the narrower type
Circular dependency Identify cycle with import graph; suggest extraction
Version conflict Check package.json / Cargo.toml for version constraints
Build tool misconfiguration Read config file; compare with working defaults

Fix one error at a time for safety. Prefer minimal diffs over refactoring.
