Contract-first API design producing OpenAPI specs, GraphQL schemas, or protobuf definitions with versioning strategy. Trigger: "design API", "OpenAPI spec", "GraphQL schema", "protobuf definition", "API contract".

REST, GraphQL, and gRPC contract analysis including versioning, consistency, and completeness. Trigger: "analyze API", "API surface", "endpoint audit", "contract analysis".

Architecture proposals with trade-off analysis, alternatives matrix, and decision rationale. Trigger: design architecture, propose solution, evaluate alternatives, create ADR.

C4 model diagrams, component relationships, and architectural pattern identification. Trigger: "map architecture", "C4 diagram", "component diagram", "system context".

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

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

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

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

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

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

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.

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".

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.

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 "sync upstream", "update from IIC/kit", "pull latest framework", "sync intent integrity chain", "update SDD engine", or "reapply brand overlay". It syncs the upstream IIC/kit repository and reapplies the MetodologIA brand layer. Use this skill whenever the user mentions sync, upstream, IIC/kit update, or brand reapplication.
