behavior-contracts skillA
behavior-contracts is agent-read markdown (skill) from tjcages/skills: Keep multi-platform products behaviorally one product: write platform-neutral behavior contracts per form/primitive, let each kit satisfy them natively, audit contract drift (not screenshots). Use when adding a second surface (web/iOS/macOS), when parity tickets pile up, when lightboxes/composers fork, or the user asks for behavior contracts / platform parity / kit drift. NOT for single-platform apps or pure visual QA..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Behavior contracts Chat: [RESPONSE.md](./RESPONSE.md). Full method: [METHODOLOGY.md](./METHODOLOGY.md). ## Operating order ### 1. Need contracts? (§1) One platform forever → skip. Second surface or parity pile-up → continue. ### 2. WHAT/HOW clear? (§0) Domain forms vs kit presentation. No WHAT nouns → `constitution-first` first. ### 3. Author contracts (§4) Per form: name · verbs (≤12) · invariants · kit owners · 90/10 · one parity check. ### 4. Install (§3) Constitution chapter and/or `docs/behavior-contracts.md`, linked from agent instructions. ### 5. Drift audit (§6) Verb × platform = present / partial / missing. File gaps. Log EXAMPLES.md. ### 6. Score (§8) ≥12/16, no 0 on #1–#5. ### 7. Hand off New surfaces in a migration → `lossless-migration` phase rules. AI accept/diff verbs → `accept-gated-ai`. ## Out of scope Pixel-matching. Shared-code mandates. Single-platform kits. Building Socials UI in this pack’s name.

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
