Install the verification-before-completion skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/cc10x/skills/verification-before-completion ~/.claude/skills/verification-before-completion
available in every project

Rules

  • Never claim "should work" without evidence
  • Never claim success without exit code 0
  • Never claim a bug is fixed without reproduction failure
  • Always capture and report exit codes
  • Always run the full test suite, not just targeted tests
  • Use timeout guards (timeout 60s) to prevent hanging

When to Use

  • Before completing any BUILD workflow step
  • Before claiming a DEBUG fix is verified
  • Before approving a REVIEW result
  • Before marking any task as done

Agents Used

  • integration-verifier (primary consumer)
  • component-builder (TDD evidence)
  • bug-investigator (fix evidence)
