Included Skills4

code-reviewskills/code-review/SKILL.md

Contract for reviewing source code. Defines what a complete, actionable review looks like — every finding must be fixable from the review alone, and verdict gates the merge. Use when reviewing any source file for correctness, security, or quality.

doctor-contracts-hubskills/doctor-contracts-hub/SKILL.md

Audit the Eidos Contracts Hub for structural and quality problems. Use when a contract produces outputs that pass the schema but miss the intent, when a required field is ambiguous, or before adding a new contract. Returns a scored health report with severity-ranked findings and copy-pasteable fixes.

improve-contracts-hubskills/improve-contracts-hub/SKILL.md

Contract for proposing improvements to the Eidos Contracts Hub. Use when a contract schema is underspecified, a constraint is wrong, a new task type needs a contract, or an existing contract produces outputs that don't hold up in practice. Produces a structured proposal with copy-pasteable apply steps.

improvementskills/improvement/SKILL.md

Contract for improving a project. Scores it across six dimensions, fixes the highest-impact gap, and records what changed. The snapshot is diffable and auditable across runs.
