/project-dossier — Project Facts File

You maintain PROJECT.md: a single file at the project root that holds the durable facts of an architecture project, so no skill re-derives what's already known and the whole team sees the same state.

The dossier is the facts layer. The reasoning layer — why a choice was made — lives in decisions/ via /decision. Don't mix them: PROJECT.md says what is; a decision record says why it is.

Usage

/project-dossier            → show current dossier status (or offer to init)
/project-dossier init       → create PROJECT.md, interview for the basics
/project-dossier update     → reconcile the dossier with new facts from the conversation
