Decomposes monoliths into microservices using bounded contexts, DDD, and service boundary analysis. Trigger: "decompose microservices", "bounded contexts", "service boundaries", "DDD decomposition", "split monolith".

Generates C4, sequence, flow, and architecture diagrams in Mermaid syntax for technical documentation. Trigger: "diagram", "mermaid", "C4 diagram", "sequence diagram", "flowchart", "architecture diagram".

This skill should be used when the user asks to "create workspace", "list workspaces", "select workspace", "archive workspace", "manage workspace sessions", or "switch task context". It manages per-task workspace sessions with isolated inputs, RAG files, logs, and tasklog per interaction. Use this skill whenever the user mentions workspace, session management, task isolation, or context switching.

SDD Phase 0 — Define governance principles, coding standards, quality gates, and TDD policy. Enhanced: validates context.json, updates pipeline state, suggests workspace creation.

SDD Phase 1 — User Specs from natural language. FR-NNN, SC-NNN, acceptance scenarios. Enhanced: bug-fix intent detection, semantic diff on re-run, workspace RAG capture.

SDD Phase 2 — Technical Specs: architecture, data model, API contracts, technology decisions. Enhanced: Tessl tile discovery, context validation, schema enforcement.

SDD Phase 3 — BDD Analysis quality checklists. [GATE G1] Enhanced: mandatory gate enforcement, FR→plan alignment check.

SDD Phase 4 — Gherkin BDD test specs with cryptographic assertion hashing. Enhanced: SHA-256 hash generation, traceability tag validation, assertion integrity.

This skill should be used when the user asks to "check status", "show pipeline status", "view progress", "what phase am I on", "show feature stages", or "display pipeline overview". It runs the status script to display a visual pipeline table with phase dots, feature stages, and next step recommendations. Use this skill whenever the user mentions status, progress, pipeline overview, or current phase.

This skill should be used when the user asks to "create a new SDD skill", "scaffold a skill", "forge a skill", "build a new command", or mentions "skill creator". It manufactures production-grade SDD/IIKit skills with full scaffolding: SKILL.md, scripts, templates, references, hooks, evals, and knowledge graph registration. Use this skill whenever a new pipeline phase, utility command, or experience skill is needed — even if the user just says "I need a new /sdd command".

SDD Phase 5 — Dependency-ordered task breakdown with parallel markers and story labels.

This skill should be used when the user asks to "run sentinel", "check project health", "scan for drift", "detect stale artifacts", "run perceive-decide-act cycle", or "audit pipeline state". It executes a full sentinel cycle (perceive-decide-act) with zero LLM cost to detect stale artifacts, missing files, health regression, and drift from constitution principles. Use this skill whenever the user mentions sentinel, health check, drift detection, or pipeline audit.

SDD Phase 6 — Cross-artifact consistency validation, traceability FR→TS→Tasks. Enhanced: knowledge graph rebuild, orphan detection, health scoring.

SDD Phase 7 — Iterative TDD implementation with BDD verification chain. [GATE G2] Enhanced: mandatory gate, step coverage verification, assertion integrity, feature immutability.

SDD Phase 8 — Export tasks to GitHub Issues with labels and dependencies. [GATE G3] Enhanced: mandatory gate, issue-map tracking, cross-check verification.

SDD Bug report + fix tasks. Enhanced: Quick Flow triage, GitHub issue inbound (#number), scope guard against AP-06 (consecutive quick flows).

SDD Utility — Resolve ambiguities in any artifact at any phase. Enhanced: auto-detect artifact, structured questions per ambiguity taxonomy, RAG capture.

SDD project initialization, status, feature selection, and help. Enhanced fork of iikit-core with workspace sessions, heartbeat init, ALM deployment, and SDD branding.

This skill should be used when the user asks to "show menu", "list all commands", "what commands are available", "show command palette", "help with SDD commands", or "what can SDD do". It displays the interactive command palette organized by category (pipeline, intelligence, utility, experience) with descriptions and aliases. Use this skill whenever the user mentions menu, command list, help, or available commands.

This skill should be used when the user asks to "browse RAG memory", "search captures", "list memory files", "find past inputs", "show knowledge base", or "review stored context". It browses and searches the RAG memory archive indexed in rag-index.json. Use this skill whenever the user mentions memory browsing, RAG search, captured files, or knowledge base exploration.
