Claude Skills by LiorCohen

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

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

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.

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.

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

Standards for how plugin prompt files (skills, agents, commands) invoke and reference the SDD system CLI.

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

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

Displays installed and project plugin versions with mismatch detection.

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

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.

Routes /sdd-run commands to fullstack-typescript skills or system CLI.

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

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

Integration testing patterns - database setup/teardown, API testing, contract testing, and Testkube execution.

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

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

Orchestrates local Kubernetes development environment management.

Agent assignment guidance, architecture patterns, and dependency ordering for fullstack-typescript plans.
