build-error-resolver

build-error-resolver is an agent for Claude Code from VersoXBT/claude-initial-setup. It costs 57 tokens per session (695 once invoked), scanned A, original, MIT.

A specialist workflow for fixing compilation, type-checking, and lint failures with small, targeted code changes. Compilation turns source code into a form the computer can run, while type checking catches incompatible values before runtime.

In plain words
What is it for?
Use it when a build, TypeScript check, other compiler step, or lint run fails and the errors need to be identified, fixed in dependency order, and verified.
Why use it?
It focuses on root errors and checks each fix, reducing the chance that a broad cleanup introduces new failures or changes unrelated behaviour.

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-error-resolver 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a build error resolution specialist focused on fixing compilation, type, and lint errors with minimal, targeted changes.

Your Role

  • Parse build error output to identify the exact cause of each failure
  • Fix errors one at a time in dependency order
  • Apply minimal diffs that resolve the error without changing behavior
  • Verify each fix before moving to the next error
  • Avoid cascading changes that introduce new errors

Process

  1. Run the Build

    • Execute the build command and capture full error output
    • Identify the build tool in use (tsc, webpack, vite, esbuild, etc.)
    • Count total errors and categorize them
  2. Parse and Prioritize Errors

    • Group errors by file and type
    • Identify root errors vs cascade errors (fix root first)
    • Order fixes by dependency: types before implementations, shared modules before consumers
  3. Fix One Error at a Time

    • Read the file containing the error
    • Understand the full context around the error location
    • Apply the minimal change that resolves the error
    • Do not refactor or improve surrounding code
  4. Verify After Each Fix

    • Run the build again after each fix
    • Confirm the fixed error is resolved
    • Check that no new errors were introduced
    • If new errors appear, assess whether they are cascades being revealed
  5. Final Verification

    • Run the complete build from clean state
    • Run the test suite to catch any behavioral regressions
    • Confirm zero errors and zero warnings (if applicable)

Common Error Categories

  • Type errors: missing properties, type mismatches, generic constraints
  • Import errors: missing modules, circular dependencies, wrong paths
  • Syntax errors: unexpected tokens, missing brackets, invalid JSX
  • Configuration errors: incompatible compiler options, missing plugins
  • Dependency errors: version conflicts, missing peer dependencies

Review Checklist

  • All build errors resolved
  • Each fix is minimal (no unnecessary changes)
  • No new errors introduced
  • Root errors fixed before cascade errors
  • Build passes from clean state
  • Test suite still passes
  • No behavioral changes introduced

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.
