Skill Claude CodeCodex
AI-native Product Requirements Document builder for new and existing products. Walks through structured discovery, market research, and generation phases to produce comprehensive PRDs aligned with the 7-section accelerator framework. Detects existing codebases and pulls context before interviewing the user. Use when…

Phase 1 of PRD Builder. Scans existing codebases to understand what's built, then walks the user through a structured discovery interview covering problem, target user, features, priorities, and AI considerations.
Skill Claude CodeCodex
Phase 3 of PRD Builder. Synthesizes discovery notes and research into a complete Product Requirements Document using the 7-section accelerator framework with AI-native extensions.

Phase 2 of PRD Builder. Conducts web research to gather market context, competitive landscape, user patterns, and relevant insights that strengthen the PRD with real-world grounding.
Skill Claude CodeCodex
Phase 4 of PRD Builder. Pressure-tests the generated PRD by reviewing it from multiple perspectives, identifying gaps and assumptions, and iterating with the user until the document is solid.

Spec-Driven Development protocol that runs before every new project or major feature. Creates structured, LLM-optimized specifications that enable one-shot implementation. Guides through 4 sequential phases: Specify, Plan, Tasks, Implement. Detects when specs are needed vs. when to just build. After spec creation…

Phase 2 of Spec-Driven Development. Translates approved SPEC.md into a comprehensive technical plan covering tech stack, data models, API contracts, file structure, and architectural constraints. Output: PLAN.md optimized for LLM implementation.
Skill Claude CodeCodex
Phase 3 of Spec-Driven Development. Transforms approved SPEC.md and PLAN.md into atomic, dependency-ordered tasks. Each task touches 1-3 files maximum and is independently testable. Output: TASKS.md optimized for sequential LLM execution.
Skill Claude CodeCodex
Deploys Spec-Driven Development into an existing project. Scans codebase, build logs, CLAUDE.md, git history, and file structure to reconstruct a baseline understanding of the project's current state. Produces BASELINE.md that anchors all future spec work. Use when applying SDD to projects already in progress.
Skill Claude CodeCodex
Phase 1 of Spec-Driven Development. Interactive specification gathering that produces a comprehensive SPEC.md covering business logic, user journeys, edge cases, success criteria, and invariants. Optimized for LLM consumption.
Skill Claude CodeCodex
Syncs SDD outputs to project management tools. Pushes TASKS.md to GitHub Projects as issues, SPEC.md to Linear as documents/initiatives. Handles bidirectional sync setup between GitHub Projects and Linear. Use after specs are finalized.

Post-spec tool discovery, environment setup, and pre-flight checklist agent. Analyzes SPEC.md, PLAN.md, and TASKS.md to identify all required tools, MCPs, packages, and services. Inventories ALL available tools in the session. Automatically installs what it can, then produces a pre-flight checklist so the user can…
