Project Dossier

/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

Hard rules

1. Every entry carries a source and a date. FAR 6.02 (PLUTO, 2026-06-10) — never an orphan number. If the user states a fact verbally, the source is client, YYYY-MM-DD.
2. Update in place, never duplicate. If a fact changes (re-run analysis, corrected input), replace the value and refresh the source/date. The dossier holds current state, not history — history is git's job.
3. Facts only. "Zoning district: R7A" belongs here. "We chose the UAP bonus over the contextual envelope" is a decision — propose /decision instead.
4. Project facts only. User preferences, workflow habits, and firm conventions do NOT belong in the dossier — Claude Code's own memory (CLAUDE.md, auto memory) handles those.

On init

1. If PROJECT.md already exists, say so and switch to update mode.
2. Ask for whatever basics aren't already evident from the conversation (one question, grouped): project name, address, client, jurisdiction.
3. Write PROJECT.md from the template below, filling what you know, leaving the rest blank.
4. If the working directory is a git repo, suggest committing it: the dossier is meant to be shared with the team.

On update

1. Read PROJECT.md.
2. Collect new facts from the current conversation (analysis results, corrected values, user statements).
3. Apply rule 2 — replace stale values in place, append genuinely new ones to the right section, each with source + date.
4. Show a short diff-style summary of what changed.

Template

# Project Dossier — {project name}

> Maintained by Architecture Studio skills and the project team.
> Every entry carries a source and a date. Facts only — rationale lives in the decisions/ directory.

## Identity

## Site

<!-- site-planner skills append here: climate, flood, transit, demographics, context -->

## Zoning

<!-- zoning skills append here: district, FAR, envelope results, overlays, landmark status -->

## Program

<!-- programming skills append here: headcount, space program, occupant loads -->

## Code

| Item | Value | Source | Date |
|------|-------|--------|------|
| Building code edition | | | |

## Decisions

<!-- maintained by /decision — do not edit by hand -->

| # | Decision | Status | Date |
|---|----------|--------|------|

How other skills use the dossier

Analysis skills in this marketplace check for PROJECT.md before fetching (don't re-derive what's on file) and append their key findings after completing. That behavior lives in each skill — your job here is only init, update, and keeping the file well-formed.
