What problem does it solve? Teams repeat the same mistakes because lessons from finished work are never written down. This Skill turns completed PRs and repeated corrections into durable, searchable solution notes that future agents and engineers can read. ## Core Features & Use Cases - Solution Note Creation: Copies the templates/compound/SOLUTION.md template into docs/solutions/<slug>.md and fills in Problem, What worked, Prevention, and Evidence sections. - Gate Verification: Runs scripts/compound_gate.py with --json --slug to confirm the note passes the readiness gate before claiming the learning is compounded. - Prevention Encoding: Converts lessons into gates, skills, or AGENTS.md / CLAUDE.md bullets so the same correction never appears twice. - Use Case: After merging a non-trivial bug fix, generate a docs/solutions note, verify it with the compound gate script, and commit it alongside the fix PR. ## Quick Start After finishing this PR, write a compound solution note in docs/solutions and verify it with the compound gate script.
