Skill Claude CodeCodex
Use for database schema/model/query changes AND new entity/relation/document modeling — SQL, NoSQL, ORM, indexes, constraints, data safety. Once a migration file exists, hand off to migration-review.
Skill Claude CodeCodex
Deep multi-source research — fan-out searches, fetch primary content, cross-verify claims, synthesize a cited report. Invoke via /deep-research.
Skill Claude CodeCodex
Use for README, setup instructions, changelog, API docs, and short documentation updates.
Skill Claude CodeCodex
Audits environment variables across the codebase — missing declarations, leaked defaults, unused vars, .env.example drift. Invoke via /env-audit.
Skill Claude CodeCodex
Use for scoped medium feature implementation after task is clear. Prefer one small diff and existing project patterns.
Skill Claude CodeCodex
Use before implementing large, multi-file, architecture, DB, auth, payment, or unclear features. Produces a detailed plan; no code.
Skill Claude CodeCodex
Use when starting a new project from scratch. Establishes contracts, design system, and architecture skeleton before any feature code. Enforces phase gates to prevent incoherence and bugs.
Skill Claude CodeCodex
Use to coordinate a live production incident or outage — triage severity, decide which guards to dispatch in what order, keep one timeline. Produces the dispatch plan only; the caller invokes each guard.
Skill Claude CodeCodex
Use to diagnose a senior-dev-kit installation — component file counts, settings merge state, and version drift. Read-only.
Skill Claude CodeCodex
Install the parts of Senior Dev Kit a plugin cannot carry — the path-scoped rules and the deny list — into the user's Claude Code settings directory.
Skill Claude CodeCodex
Use for migration files, destructive changes, production data risk, rollback strategy, and backward compatibility. Deployment-safety phase that follows db-change once a migration file exists.
Skill Claude CodeCodex
Use when building a brand-new admin panel page or screen from scratch in ANY web framework. Enforces design quality gates. Do NOT use for modifying existing pages — use ui-change instead.
Skill Claude CodeCodex
Use when building a brand-new mobile screen, bottom sheet, or major UI section from scratch in Kotlin/Compose, Flutter, or Swift/SwiftUI. Enforces design quality gates. Do NOT use for modifying existing screens — use ui-change instead.
Skill Claude CodeCodex
Use for slow code, slow queries, bundle size, caching, N+1, render loops, memory, and latency issues.
Skill Claude CodeCodex
Use to persist durable project-level facts (decisions, gotchas, non-obvious conventions) to a project memory file so future sessions don't rediscover them. No code changes.
Skill Claude CodeCodex
Use for safe refactors that preserve behavior. Keep diffs small and verification strong.
Skill Claude CodeCodex
Use before release/deploy to run a GO/NO-GO safety checklist — build, tests, migrations, env vars, security scan, backward compat, rollback, known risks.
Skill Claude CodeCodex
Use for auth, permissions, payment, secrets, input validation, session/token handling, SQL/NoSQL injection, and sensitive user data.
Skill Claude CodeCodex
Use for dependency audits (CVEs, outdated majors, paid licenses, bloat), secret scans, SAST, and container/filesystem scans. Not for low-risk UI-only tasks.
Skill Claude CodeCodex
Use to add or update tests using the existing test framework for changed behavior, edge cases, regressions, or existing untested code the user wants covered.
Skill Claude CodeCodex
Use for small UI changes: modal, button, responsive layout, component styling, Tailwind/CSS. Do not use for backend, auth, database, or payment.
