AI Agent Skills

Use to produce a Software Architecture Document for a feature — Arc42 12 sections + C4 L1/L2 inline + ADRs spawned on a blast-radius gate — once spec.md exists. Triggers…

Use to turn a raw feature idea into a reviewed spec.md — a lightweight Socratic interview front (capture the idea, deep-dive the problem) merged with a full product spec…

Use to implement a feature from its tasks.json with test-driven development — writes a failing test first, makes it pass, refactors, gates, and commits per task. Trigger…

Use to run an ambiguity sweep over a written spec.md and close every under-specified point before planning or design proceeds — so two engineers can't reasonably build d…

Use to establish the project's design canon — docs/design-system.md: the design-tool choice (Figma MCP / Pencil MCP / code-only markdown), the platform posture (mobile-f…

Use to fix a reported bug spec-first: reproduce it, trace the symptom to the owning feature's acceptance criteria, pin it with a failing (RED) test, apply the minimal GR…

Use BEFORE roadmap or specify to get the idea OUT OF YOUR HEAD and onto disk — a Socratic interview that surfaces hidden assumptions, names tradeoffs, exposes imprecisio…

Use to run an independent, clean-context code review of an implemented feature against its spec and acceptance criteria before shipping. Triggers on "review {slug}", "co…

Use to break a product idea into incremental steps and keep that decomposition living — one docs/roadmap.md with a destination sentence, the steps table (source-anchored…

Use to close the loop after review — verify the feature actually works, write the changelog / knowledge-base note, and open the pull request. Triggers on "ship {slug}",…

Use to establish the repo's architecture map the rest of the pipeline reads. Two modes: on an EXISTING codebase it scans once and persists what's there; on an EMPTY/gree…

Turn approved specs into long-running autonomous implementation. A minimal, adaptable SDD harness with Agent Skills for Claude Code, Codex, Cursor, Copilot, Windsurf, Op…

Add or extend coding-agent support in cc-sdd by executing the SOP in docs/cc-sdd/sop-new-agent.md end-to-end. Use when introducing a new agent, adding a subagent-capable…

Don Cheli — SDD Framework. The most comprehensive Specification-Driven Development framework for AI agents. 88+ commands, 51 skills, 15 reasoning models. TDD mandatory,…

Bootstrap the SDD constitution (specs/mission.md, specs/tech-stack.md, specs/roadmap.md) from current repository evidence. Refuses by default if any of the three files a…

Append a new active phase to specs/roadmap.md. Parses existing phases (active and ✅-completed) to compute the next stable phase number per the lifecycle rule, grounds th…
