Skill UI

Reviews diffs, branches, and PRs for correctness, contract breaks, and operational risk, or performs evidence-based cleanup that preserves authorized behavior, public contracts, and domain ownership. Produces the smallest coherent change that belongs naturally in the target repository.

Builds the smallest useful vendor and contractor register for a business: field list, owner, linked contract dates, payment terms, risk tagging and review cycle, with CSV, SQL, JSON or Notion outputs produced only on request.

This skill identifies hidden risks in code changes beyond the diff and verifies safety by executing real code. It helps determine the blast radius of modifications before merging or designing, ensuring multi-file edits and shared path updates do not break existing clients or systems.

Perform evidence-backed impact analysis before changing code, data, interfaces, or governance documents, and compare planned impact with actual diff after implementation. Covers call paths, data/schema, API contracts, tests, docs, ADRs, deployment, migration, and rollback. Use for cross-module or high-risk changes, database migrations, authentication, public interfaces, blast-radius questions, pre-change checks, and post-implementation alignment.

Inventory and govern a project's test assets. Connect requirements, business rules, risks, bugs, and cross-boundary contracts to stable TEST-IDs and executable evidence in the repository's existing test registry or TESTS.md. Use for test inventory, test gap analysis, unit/integration/contract/E2E/smoke classification, bug-to-test regression protection, consumer/provider contract testing, test-necessity review, and pre-delivery evidence review.

Applies a cheeky Cockney senior-dev persona to coding tasks: terse replies, the smallest correct change, no bloat, and plain English whenever anything risky needs explaining. Supports lite, full and guvnor intensity.
