Skill Claude CodeCodex
Use the IDE AskQuestion tool when the agent needs user input. Use when asking the user to choose between options, confirm a decision, or pick from discovered alternatives — never ask multiple-choice questions in plain chat.
Skill Claude CodeCodex
Diagnose database issues via SQL row counts without seeing actual data values. Use when debugging missing or incorrect database data, 500 errors traced to queries, or data integrity issues where the user runs SQL and reports only row counts back.
Skill Claude CodeCodex
Analyses git changed files in the workspace and makes atomic, functional, and semantic commits using conventional commits format. Use when the user asks to commit changes, create commits from staged/unstaged files, or organise working tree changes into meaningful commits.
Skill Claude CodeCodex
Analyse a repository's real architecture and write or refresh the Project Architecture section in FRAMEWORK.local.md for projects using the Custom Architecture capability.
Skill Claude CodeCodex
Use this skill when creating, reviewing, or migrating relational database schemas. It applies across projects and ORMs/frameworks such as Symfony Doctrine, Prisma, Drizzle, Rails ActiveRecord, Laravel Eloquent, raw SQL, or any other relational database layer.
Skill Claude CodeCodex
Use DBML as the standard format for database schema documentation. Apply this whenever creating, updating, reviewing, or repairing database docs, ERDs, schema diagrams, table inventories, migration summaries, Doctrine migration changes, SQL schema docs, ORM model docs, or CI schema drift failures. Prefer…
Skill Claude CodeCodex
Distil reusable engineering rules from code changes and record them in docs/rules/. Use whenever the user wants to extract rules, conventions, or lessons from a diff, a commit, or the current uncommitted changes — e.g. "extract the rule from these changes", "what convention does this commit establish", "record this as…
Skill Claude CodeCodex
Use this skill for frontend UI work that must preserve or extend a product's real design system: new screens/components, high-fidelity rebuilds, restyles, non-trivial forms, role-gated UI, substantial behavior changes, or UI implementation that needs layout, experience, style-guide, clean implementation planning, and…
Skill Claude CodeCodex
Enforce semantic line breaks in Markdown specification prose. Use this whenever creating or editing specs, requirements, ADRs, README-style specification docs, or Markdown under specs/ or docs/, especially when paragraphs would otherwise be written as long wrapped lines. Apply it for AI-written specs and for…
Skill Claude CodeCodex
Read-only cross-artefact consistency check across spec.md, plan.md, and tasks.md, ideally by an agent that did not write them. Detects coverage gaps, conflicts, FRAMEWORK.md violations, and plan claims about the code that do not hold, before implementation begins.
Skill Claude CodeCodex
Audit requirement quality across spec.md, plan.md, and tasks.md for a chosen domain (UX, API, security, performance…). Writes reviewer-owned checklists that test whether requirements are complete, clear, measurable, and consistent — unit tests for the requirements, not for the code.
Skill Claude CodeCodex
Resolve ambiguities in a feature spec through targeted Q&A, one question at a time, recording each answer in spec.md as it is given. Run after spec-kit-specify when open questions remain, and before spec-kit-plan.
Skill Claude CodeCodex
Execute tasks from tasks.md following TDD, marking tasks complete as it goes and working the Documentation phase that updates specs/features/. Run after spec-kit-analyse, and again after spec-kit-converge appends tasks.
Skill Claude CodeCodex
Create a technical implementation plan from a feature spec. Documents architecture, data models, interface contracts, exceptions and the records the change affects, checked against the code as it is, without generating code. Run after spec-kit-clarify.
Skill Claude CodeCodex
Create a feature specification from a user description, with identified user stories, requirements and edge cases. Focuses on WHAT and WHY, never HOW. Use at the start of a spec-kit workflow.
Skill Claude CodeCodex
Generate a dependency-ordered, phase-based task list from spec.md and plan.md, each task citing the requirements it delivers and ending on a Documentation phase. Run after spec-kit-plan and before spec-kit-analyse.
Skill Claude CodeCodex
Extracts exact, behaviour-first specifications from an existing codebase. Defines domain concepts, use cases, and business rules with precision — zero implementation details. Use when reverse-engineering a legacy project into precise specs or preparing an AI-friendly spec set for a rewrite.
Skill Claude CodeCodex
Interprets authoritative specs and helps design a new implementation collaboratively, preserving required business, API, and database contracts while exploring architecture, stack, and delivery options with the user. Use when the user wants to start a new project from frozen specs, discuss implementation approaches…
Skill Claude CodeCodex
Generate, improve, and validate Claude Code /goal prompts that are specific, scoped, verifiable, and safe. Use when the user asks to create, rewrite, improve, or evaluate a /goal.
Skill Claude CodeCodex
Assess implemented work against its change's spec.md, plan.md and tasks.md, ideally by an agent that did not do the work, and append every gap to tasks.md as a Convergence phase for spec-kit-implement to complete. Changes no code, spec or plan. Run after spec-kit-implement.
Skill Claude CodeCodex
Turn a feature's intent, pseudo-specification and branch changes into UAT artifacts - a scenarios TSV, a SQL file (data search queries or mock fixtures) and an optional testing-session playbook. Use when asked to prepare, design or write UAT scenarios, UAT fixtures, test data for UAT, or a UAT playbook for a branch or…
