What problem does it solve?
This Skill helps you make Tier 2 reliability and correctness changes without breaking a previously green Tier 1 system, especially when the work must be audited and proven with tests.
Core Features & Use Cases
- Negative-path hardening: Add and validate tests for denied, paused, misordered, or corrupted states before changing runtime behavior.
- Guarded implementation: Apply the smallest fix needed for permission enforcement, hooks, compaction, token accounting, cost limits, and session or config correctness.
- Regression-safe validation: Run the required crate tests, checks, clippy, and integration assertions, then report machine-readable evidence for mission review.
Quick Start
Use this skill to assess the mission’s Tier 2 reliability feature, confirm Tier 1 is green, implement the smallest audited fix, and return validation evidence with the exact commands you ran.
