Bug Reproduction Brief

Use this skill when a bug report is incomplete, intermittent, environment-specific, or mixed with an assumed cause. The goal is to prove the smallest observable failure before diagnosis or repair begins.

1. Record the observed failure

Capture the exact error, incorrect output, timestamp, affected route or command, and the smallest known input. Preserve relevant logs without secrets or personal data. Label second-hand descriptions as unverified.

2. Identify the environment

Record only facts you can inspect:

• repository and commit;
• runtime and package-manager versions;
• operating system or container;
• dependency lockfile;
• relevant feature flags;
• whether the target is local, test, staging, or production.
