type-driven SKILL.md skillA
type-driven from outlinedriven/odin-claude-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/odin-claude-plugin/type-driven@git:20260904.2014e73Pins git:20260904.2014e73 in mdr.lock. Pin the fingerprint instead.

Use when modeling a domain, encoding a state machine, hardening APIs, making invalid states unrepresentable, or parsing instead of validating. Not for TypeScript: use typescript-best-practices.
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
# Type-driven development ## Contract | Field | Bound contract | |---|---| | Trigger | The work is modeling a domain, encoding a state machine, hardening an API boundary, making invalid states unrepresentable, or parsing instead of validating. | | Authority | Reversible local: writes only domain types, public signatures, and affected callers and tests; rollback is version control or undo. No remote mutation. | | Side effect | Rewrites domain types, public signatures, and affected callers and tests to the new algebraic model. | | Done | Invalid states are unconstructible, matches are exhaustive, boundaries parse, and no scattered post-hoc validation remains. | ## Inputs Required: the domain problem, data model, or API surface to encode. Optional: existing types or callers to refactor. ## Refusals - Will not add runtime guards to fix a type-design failure: fix the type design. - Will not add a wildcard arm to silence a non-exhaustive match: add the missing variant. - Will not proceed with type holes or incomplete bodies. - Will not use this approach when the language lacks ADTs, sealed hierarchies, or equivalent sum-type support: skip and report. ## Procedure …

How to install
mdr add outlinedriven/odin-claude-plugin/type-driven@sha256:2b331c42fc4e19d1The 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.
