Before implementing new code (endpoints, components, services, models), search the codebase for existing patterns to reuse. Prevent code duplication by finding and suggesting similar implementations. Auto-trigger when user asks to create, implement, add, or build new functionality.

Audit and refactor CLAUDE.md files to eliminate bloat, enforce context engineering best practices, and create folder-level CLAUDE.md files for complex domain-specific instructions.

grep -c "\[NEEDS CLARIFICATION" specs/NNN-slug/spec.md

Systematic debugging techniques including error classification, root cause analysis (5 Whys), reproduction strategies, and error documentation. Use when debugging errors, investigating failures, analyzing stack traces, fixing bugs, or documenting errors in error-log.md. (project)

**Version**: 2.0.0 **Purpose**: Generate and maintain design system tokens across all project surfaces (UI, emails, PDFs, CLI, charts, docs)

> Standardized boot-up ritual and memory access patterns for stateless agent workflows.

Preview command effects without making changes. Simulates file writes, git operations, agent spawns, and state changes. All reads execute normally for accurate preview. Use --dry-run flag on any command.

Generate research and planning prompts for epic workflows using isolated sub-agents.

Interactive question bank-driven scoping for epic workflows.

Generate sprint breakdown with dependency graph and execution layers for epic workflows.

Generate comprehensive walkthrough documentation and trigger self-improvement for epic workflows.

Completes feature/epic workflows after deployment with comprehensive walkthrough generation for epics (v5.0+), roadmap updates, artifact archival, documentation, and branch cleanup. Use after /ship-prod, /deploy-prod, or /build-local completes, or when user asks to finalize. (project)

Enforce git commits after every phase and task to enable rollback and prevent lost work. Auto-trigger when completing phases, tasks, or when detecting uncommitted changes. Auto-commit with Conventional Commits format. Verify branch safety, check for merge conflicts, enforce clean working tree. Block completion if changes not committed.

Executes implementation tasks using Test-Driven Development, prevents code duplication through anti-duplication checks, and maintains quality through continuous testing. Use when implementing features from tasks.md, during the /implement phase, or when the user requests TDD-based implementation. (project)

Extract reusable components from approved HTML mockups during implementation. Identifies patterns, maps CSS to Tailwind, and populates prototype-patterns.md for visual fidelity. Use at start of /implement for UI-first features.

Execute multi-agent voting for critical decisions using MAKER-style first-to-ahead-by-k error correction.

Validates production readiness through performance benchmarking, accessibility audits, security reviews, and code quality checks. Use after implementation phase completes, before deployment, or when conducting quality gates for features. (project)

Identify and execute independent operations in parallel for 3-5x speedup. Auto-analyzes task dependencies, groups into batches, launches parallel Task() calls. Applies to /optimize (5 checks), /ship pre-flight (5 checks), /design-variations (N screens), /implement (task batching). Auto-triggers when detecting multiple independent operations in a phase.

Generates implementation plans with code reuse analysis, architecture design, and complexity estimation during the /plan phase. Use when planning feature implementation, analyzing code reuse opportunities, or designing system architecture after specification phase completes. Integrates with 8 project documentation files for constraint extraction. (project)

Executes production deployment workflow by promoting validated staging builds to production with semantic versioning, health checks, and release tagging. Use when running /ship-prod command, deploying to production after staging validation, or promoting staging builds to production environment.
