spec-writer skillA

spec-writer is agent-read markdown (skill) from jpeetz/agent-skills: Use this skill when a vague feature request, ticket, PRD fragment, or rough idea needs to be turned into a structured specification, technical plan, and ordered task breakdown for AI coding agents. Generates all three output sections immediately, then flags every implicit decision as an inline [ASSUMPTION: ...] marker with an impact rating and correction guidance — no back-and-forth questions needed before drafting. Primary keywords: spec-driven development SDD, feature specification generation,.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add jpeetz/agent-skills/spec-writer@v1.0.0
Exact content
mdr add jpeetz/agent-skills/spec-writer@sha256:0fd6e14d636b0365

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
