contract-driven SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
contract-driven from outlinedriven/odin-claude-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when crossing a public API boundary, guarding complex invariants, or hardening untrusted input or integration seams. Not for remote or irreversible changes.
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
# Contract-driven ## Contract | Field | Bound contract | |---|---| | Trigger | Crossing a public API boundary, guarding complex invariants, or hardening untrusted input or integration seams. | | Authority | Reversible local: writes only named local types, assertions, validators, and tests at contract boundaries; rollback is undo (delete the added code or revert the boundary change). No remote mutation. | | Side effect | Adds or refines local types, assertions, validators, and tests at contract boundaries. | | Done | Every planned contract is implemented at the appropriate static/test/debug/runtime layer and violations fail explicitly at the boundary. | ## Inputs Required: - The requirements or specification for the operation whose contract is being designed. - The target source file or module containing the public API boundary, invariant, or untrusted seam. Optional: - Existing tests that must continue to pass. ## Procedure …

How to install
mdr add outlinedriven/odin-claude-plugin/contract-driven@sha256:50a4c22ee2e679a1The line at the top of this page pins the label git:20260904.2014e73, 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.
