/project-dossier

What it does

Maintains a single PROJECT.md at the project root holding the durable facts of the project — so no skill re-derives what’s already known and the whole team sees the same state.

Three hard rules:

1. Every entry carries a source and a date. FAR 6.02 (PLUTO, 2026-06-10) — never an orphan number.
2. Updated in place, never duplicated. The dossier holds current state; history is git’s job.
3. Facts only. The reasoning behind choices goes in decision records — see /decision.

The analysis skills across Architecture Studio are wired into it: due-diligence, zoning, programming, and site skills check the dossier before fetching and append their key findings after completing.

Usage

/project-dossier init       ← create PROJECT.md, answer a couple of questions
/project-dossier            ← show current status
/project-dossier update     ← reconcile with new facts from the conversation

After init, the dossier mostly maintains itself — run a zoning analysis and the district, FAR, and envelope results land in the file with their sources.
