Idempotent Redundancy

When adding redundant paths (fallbacks, belt-and-suspenders), make them idempotent.

Pattern

Redundancy without idempotency causes loops, churn, or data corruption.

DO

  • Use _is_merge: true for Braintrust updates
  • Check if value exists before writing (fallback only if missing)
  • Use atomic write/rename for file operations
  • Make reconciliation steps safe to run repeatedly

DON'T

  • Write unconditionally in fallback paths
  • Allow multiple writers to overwrite each other
  • Fire "repair" actions that can trigger more repairs

How to use it

Copy the folder

Take parcadei/idempotent-redundancy from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
