Standards for authoring SDD plugin skills — frontmatter, self-containment, and input/output schemas.

Create a commit following repository guidelines with proper versioning and changelog updates.

Spec-driven development (SDD) plugin for Claude Code — a collection of specialized AI agents, phased implementation plans, and verified code generation for full-stack teams

Shared TypeScript coding standards for strict, immutable, type-safe code.

Standards for authoring SDD plugin agents — frontmatter, self-containment, skill references, and no-user-interaction rules.

Two-step self-review at every task lifecycle phase. Step 1 (this skill) runs in-context to gather session signals — files read vs grepped, user pushback, build evidence, degradation signs. Step 2 launches a forked subagent for unbiased code/plan review with fresh eyes. Combined report classifies findings as hard blocks or soft warnings.

Validate plugin and marketplace manifest files against the official Claude Code specification

Standards for authoring SDD plugin commands — frontmatter, user interaction, skill/agent invocation, CLI integration, and output formatting.

D2 diagramming language reference for architecture diagrams, sequence diagrams, grid layouts, SQL tables, and class diagrams. Produces .d2 files rendered via CLI or playground.

Technical product expert specializing in platform engineering, DevOps, and AI dev tools. Critically reviews the SDD plugin for DX issues, inconsistencies, and gaps.

Manage tasks and plans using the .tasks/ directory.

Writes and maintains user-facing documentation for the SDD plugin. Proactively detects when docs are out of sync with plugin capabilities.

Create change specification and implementation plan with dynamic phase generation. Supports feature, bugfix, refactor, and epic types.

Guidelines for consistent, well-documented commits in SDD projects

Displays installed and project plugin versions with mismatch detection.

OpenAPI contract standards for API specification, versioning, and type generation.

MVVM architecture standards for React/TypeScript frontends with TanStack ecosystem, TailwindCSS, and Shadcn UI.

Standards for Helm charts in SDD projects, including settings-driven patterns.

Populate domain specs (glossary, entity definitions, use-cases) from SPEC.md content during implementation.

Guided requirements gathering through structured questions to create comprehensive specifications. Produces a complete requirements document via non-blocking conversational interaction.

Templates and validation for writing product specifications.

Scaffolds Helm charts for SDD components, driven by component settings.

Scaffolds integration test suite structure with database setup, API testing, and Testkube configuration.

Process external specifications through transformation, classification, gap analysis, component discovery, and decomposition. Creates workflow items with classified context.

Scaffolds PostgreSQL database component with migrations, seeds, and management scripts.

Component type definitions, settings schemas, directory patterns, and validation rules for the fullstack-typescript tech pack.

Orchestrates the full change lifecycle — routes actions to phase-specific sub-files.

Scaffolds project-level structure (root files, specs).

Manage project settings in sdd/sdd-settings.yaml including component settings that drive scaffolding.

Single gateway for all core↔tech-pack interactions. Reads manifests, resolves paths, loads skills/agents, routes commands.

Intent-to-command mappings for fullstack-typescript tech pack features.

Scaffolds the config component for centralized configuration management, driven by component settings.

Orchestrates SDD project initialization — version detection, environment verification, scaffolding, and git setup.

Analyze specifications and decompose into independent changes.

Discover required technical components through targeted questions based on classified requirements.

CMDO architecture standards for Node.js/TypeScript backends with strict layer separation.

PostgreSQL database standards for migrations, seeds, and schema management.

Tech pack description, available commands, and getting-started guide for fullstack-typescript.

Templates and guidance for implementation plans with dynamic phase generation.

Scaffolds Node.js/TypeScript backend components with CMDO architecture, driven by component settings.

End-to-end testing with Playwright - browser automation, visual regression, test data management.

Manage spec registry and generate snapshots.

Scaffolds CI/CD pipeline definitions using GitHub Actions for build, test, lint, and deploy workflows.

Standards and patterns for SDD configuration management.

Orchestrates project configuration operations — generate, validate, diff, and add-env.

Orchestrates component scaffolding by delegating to component-specific scaffolding skills.

Shared TypeScript coding standards for strict, immutable, type-safe code.

Internal skill for managing workflow lifecycle state in sdd/workflows/. Provides session-independent, resumable workflow tracking.
