build-fix

build-fix is a command for Claude Code from RohitBind123/claude-setup. It costs 0 tokens per session (561 once invoked), scanned A, a copy of build-fix, MIT.

A command for fixing build and type errors one at a time. A build checks whether a project can be compiled or packaged, while type checking catches values used in invalid ways.

In plain words
What is it for?
Use it to detect a project's build system, run the appropriate check, group errors by file and dependency order, and make minimal fixes.
Why use it?
It turns a long list of errors into a measured sequence of small changes and verifies each fix without introducing new errors.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

build-fix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
