Writes a self-contained, step-by-step Spec-Driven Development (SDD) implementation plan for an AI coding agent to execute against an already-confirmed batch of work items (bugs, gaps, features) — exact file paths per task, EARS-style trigger/response acceptance criteria, a runnable verification command per task, explicit [NEEDS CLARIFICATION] markers instead of guessing, and dependency-ordered phases. Trigger on requests like "напиши SDD-план", "распиши план по шагам для агента…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SDD Plan Writer ## Purpose An AI coding agent stops when the work _looks_ done. Without a check the agent itself can run, "looks done" is the only signal available, and every silent mistake waits for a human to notice — this is Anthropic's own diagnosis of why plans fail in practice, not a hypothetical concern (see Anthropic's Claude Code best-practices documentation). A spec that says "add validation to the signup form" leaves the agent free to satisfy that sentence in a dozen mutually-inconsistent ways; a spec that names the exact file, the exact trigger/response behavior, and the exact command that proves it worked leaves no such freedom. This skill exists to produce the second kind of spec, not the first — every task must carry its own path, acceptance criterion, and verification command, or it does not go into the plan yet. ## When to use **Precondition — the input must already be a finite, confirmed list of work items.** Each item must already be understood well enough to name at least one concrete file it touches. Typical inputs: the Core-gap rows of a closed `axis-closure-matrix` report, an already-agreed feature …

How to install
mdr add ivanestar/eitr/sdd-plan-writer@sha256:537045355e204b2cThe line at the top of this page pins the label git:20260906.163e7f1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
