Build Error Resolver skill for Claude and Codex

Build Error Resolver as an AI skill. It asks for Build log, Build tool, What changed recently and 3 more, then does the rest. Free to install in Claude or…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when a build or CI job is failing with a long error log and the first real error needs to be isolated, fixed, and confirmed. Do not use for runtime bugs that appear after the build succeeds or slow build tuning. Related topics: coding, technical.

What it will ask you for

• Build log (longer free text)
• Build tool (free text, e.g. "Gradle or webpack or cargo")
• What changed recently (longer free text)
• Relevant files (longer free text)
• Environment (choose one: Local, CI, Docker build)
• Command that fails (free text, e.g. "The exact command")

How it works

1. Read the log from the top and identify the first real error, setting aside warnings and follow-on failures.
2. Name the file, line, and underlying cause, checking recent changes and dependency bumps first.
3. Propose the smallest edit that fixes it and explain in a sentence why it works.
4. Rebuild with the exact failing command and confirm the original error is gone.
5. If a new error appears, repeat from the top of the new log until the build is green.

What you get

The first error with its cause, the exact edit, the rebuild command with the expected clean result, and a note on any follow-up error handled.

What it watches out for

• Fixing the last error in the log, which is often just a symptom of an earlier failure.
• Deleting the lockfile or cache as a first move, which hides the cause and breaks reproducibility.
• Declaring the build fixed without re-running the exact failing command.
