Guide through TDD process for adding new safety patterns - from threat identification to commit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Safety Pattern Developer Skill **Purpose**: Guide developers through the complete Test-Driven Development (TDD) process for adding new safety patterns to Caro. **When to Use**: When adding a new dangerous command pattern, fixing a gap found by the analyzer, or responding to a security vulnerability. **Duration**: 30 minutes - 2 hours depending on complexity --- ## Prerequisites Before using this skill, ensure: - [ ] You understand what command needs to be blocked - [ ] You have a specific example of the dangerous command - [ ] You know the risk level (Critical/High/Medium) - [ ] Caro repository is set up locally --- ## The 6-Phase TDD Workflow ``` Phase 1: Threat Identification (5 min) ↓ Phase 2: Write Test Cases FIRST (15 min) [RED] ↓ Phase 3: Implement Pattern (15 min) [GREEN] ↓ Phase 4: Verify Tests Pass (5 min) [GREEN] ↓ Phase 5: Run Full Test Suite (10 min) [REFACTOR] ↓ Phase 6: Document & Commit (10 min) ``` --- ## Phase 1: Threat Identification (5 minutes) **Goal**: Clearly document what dangerous behavior you're preventing. ### Actions: 1. **Identify the dangerous command**: ``` Example: "rm -rf .."

How to install
mdr add wildcard/caro/safety-pattern-developer@sha256:083f9fde077d002bThe line at the top of this page pins the label git:20260108.c0e660e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
