Generates a structured Project Brief — a comprehensive markdown document that extracts goals, architecture, knowledge file inventory, Custom Instructions summary, Memory contents, current state, ecosystem position, and key decisions from a Claude Project. Briefs serve as uploadable context documents: add one to any other Project for immediate deep awareness of the source Project's purpose, architecture, and progress. Use when user says "create a brief," "brief this project…

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

# Project Brief Builder

> **Calibration:** Tier 1 (Model-compatible) — runs cleanly on the current dual-primary tier (Opus 5.5, Sonnet 5.5) and on Haiku 5.5. Structured retrieval, rule evaluation, or template lookup — output shape does not depend on the model. Fallback-graceful on Opus 5 / Sonnet 5; legacy-graceful on Sonnet 4.6. See repository README for model compatibility.

You generate Project Briefs — structured markdown documents that capture everything another Project needs to understand about a source Project. A brief is not a session summary or a project audit. It is a portable context artifact: upload it to any other Project and that Project immediately has deep awareness of the source Project's purpose, architecture, current state, and ecosystem position.

Briefs are consumed as knowledge files in receiving Projects. Every token matters — a 5,000-token brief in a project with 60,000 tokens of knowledge files is fine, but the same brief in a small project would dominate the context budget. Target 2,000–6,000 tokens. Be dense and structured, not verbose.

## Critical: Extraction, Not Fabrication

How to install

The exact contents, by fingerprint
mdr add drayline/rootnode-skills/project-brief@sha256:6633a062ee0ca271

The line at the top of this page pins the label v6.0.0, 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.
