spec

spec is a Planning & task breakdown skill for AI agents, published by tyrchen in the rustack repository on GitHub. Skillspace rates spec D (55/100) and it passed the safety scan; the rating is based on static analysis only.

Turn a feature idea or rough requirement into a complete, dependency-ordered spec set under ./specs — PRD, component designs, glossary, security/perf/test cross-cuts, key-decisions log, stakeholder roadmap, and engineer-facing implementation plan — cross-referenced with prior-art memos in ./docs/research and vendored code in ./vendors. Use whenever the user says "write the spec", "design this", "let's plan X", "produce a PRD / impl plan / roadmap", "restructure the specs", "review and re-organise the design", "think ultra hard and split this into phases", or describes a non-trivial system that needs a written design before code. Trigger even when the user does not say "spec" if they ask for phased delivery, milestone exit criteria, or a build-order graph.
