build-fix

A command that runs the project's Rust or TypeScript checks, finds build errors, and applies the smallest fix it can verify.

In plain words
What is it for?
Use it when a Rust or TypeScript build fails and you want errors fixed one at a time with a follow-up verification.
Why use it?
It avoids manually locating the first compiler error and making unrelated changes. It checks each fix and stops when the problem needs a larger design change.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 339 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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.

What it actually says

Build Fix

Automatically detect and fix build errors with minimal changes.

Instructions

Run the build and fix any errors found. Follow this process:

Step 1: Detect Build System

Run these checks in order:

  1. cd src-tauri && cargo check 2>&1 - Rust compilation
  2. npx tsc --noEmit 2>&1 - TypeScript type checking
  3. If a specific build command was mentioned in $ARGUMENTS, run that instead

Step 2: Parse Errors

  • Identify the FIRST error (fix one at a time)
  • Note the file path, line number, and error code
  • Read the relevant code to understand context

Step 3: Apply Minimal Fix

  • Make the SMALLEST change that resolves the error
  • Do NOT refactor, restructure, or "improve" surrounding code
  • Do NOT change unrelated code

Step 4: Verify

  • Re-run the same build command
  • If fixed, move to next error
  • If the fix created MORE errors than it resolved, REVERT and ask for help

Step 5: Guardrails

  • Stop after 3 failed attempts on the same error - explain what you tried
  • Stop if fix creates new errors - revert and explain
  • Never change architecture - if the fix requires restructuring, explain why and ask

Step 6: Report

After all errors are fixed:

## Build Fix Report
- Errors fixed: N
- Files modified: [list]
- Build status: ✅ PASS / ❌ STILL FAILING
Changes

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.

build-fix is a command published in the GitHub repository talayash/agentrium (39 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 339 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
