plan skillA

plan is agent-read markdown (skill) from archcore-ai/plugin: Plan a feature or initiative through a computed route: the conductor derives the canon delta and assembles the document package — from a zero-document null route for small fixes to an umbrella PRD with one spec per capability for large initiatives. Expert paths: sdd (full package), sources mode (MRD → BRD → URD) for market research and discovery, iso mode (BRS → StRS → SyRS → SRS) for ISO 29148 and regulated work, research for an investigation that the research instrument closes either by scope .

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 archcore-ai/plugin/plan@git:20260907.9b8b81c
Exact content

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.
