LiorCohen/sdd Skills

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

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

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

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

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

Guidelines for consistent, well-documented commits in SDD projects

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

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

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

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

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

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

Templates and guidance for implementation plans with dynamic phase generation.

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

# Plugin Testing Standards Testing methodology for Claude Code plugins ensuring deterministic verification of LLM-driven workflows. --- ## Core Principles ### 1. Separation of Concerns ``` tests/ ├── lib/ # All helper/utility code (wraps Node.js) │ ├── index.ts #

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

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

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

Analyze specifications and decompose into independent changes.

Manage spec registry and generate snapshots.

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.

Manage tasks and plans using the .tasks/ directory.

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