Skill Codex
Repository-aware implementation rules for minimal design surface, contract safety, representative patterns, and verifiable changes. Use when implementing, refactoring, or reviewing code.
Skill Codex
Determines which PRD, ADR, UI Spec, Design Doc, and Work Plan a change requires and where each document lives. Use when deciding documentation scope or creating or reviewing one of these artifacts.
Skill Codex
Resolves and records one external evidence source required by a current design or verification decision. Use when repository and supplied evidence cannot determine that decision.
Skill Codex
Selects the smallest sufficient implementation strategy and verification boundary from current requirements and repository evidence.
Skill Codex
Selects and specifies the integration/E2E tests that own accepted behavior at the boundary where it is observable.
Skill Codex
Clarifies inputs, outputs, success criteria, decisions, and unresolved conditions so downstream agents can execute without guessing. Use when writing or revising LLM-facing prompts, handoffs, planning artifacts, reviews, reports, or generated instructions.

Skill Claude CodeCodex
Create frontend work plan from design document with test skeleton generation.
Skill Claude CodeCodex
Reviews completed frontend implementation for governing-source compliance, scope economy, repository quality, and security, and applies user-approved React corrections.
Skill Claude CodeCodex

Skill Claude CodeCodex
Run the full-cycle implementation workflow for one outcome spanning backend and frontend layers.
Skill Claude CodeCodex
Orchestrate the complete implementation lifecycle from requirements through verified repository implementation.
Skill Claude CodeCodex
Creates a reviewed Work Plan with value-filtered integration/E2E test skeletons. Use when planning implementation from a Design Doc.
Skill Claude CodeCodex
Prepare repository-local execution tools when the user requests setup or a concrete build capability is unavailable.
Skill Claude CodeCodex
Proposes and, after user confirmation, creates or maintains docs/project-context/quality.yaml from repository-specific review requirements. Use when asked to generate or update a repository quality profile.
Skill Claude CodeCodex
Generate PRD and Design Docs from existing codebase through discovery, generation, verification, and review.
Skill Claude CodeCodex
Reviews completed implementation for governing-source compliance, scope economy, repository quality, and security, and applies user-approved corrections.
Skill Claude CodeCodex
Update existing design documents (Design Doc / PRD / ADR) with review and consistency verification.
