Draft Project Manual specification sections from accepted project requirements using CSI MasterFormat identities, three-part sections and review flags. Use for design requirements; use product-cut-sheet for source-faithful product entries and epd-to-spec for EPD requirements.

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

# spec-writer

Before acting, read the [host contract](../../docs/host-harness-contract.md) and this component’s [declaration](host-contract.json) (`skill:spec-writer`). Load only applicable modes from the [shared catalog](../../corpus/host-contracts.json); declarations do not grant access or permission. Use the actual host’s [delivery route](../../docs/host-adapters.md).

## Document role

Draft Project Manual sections: accepted design requirements, products/performance, submittals and execution. Keep proposed requirements distinct from adopted requirements. A product cut sheet is a different deliverable: route a source-faithful single-product PDF/URL entry to `/as:product-cut-sheet`, an FF&E book to `/as:ffe-spec-book`, and EPD/GWP requirements within Project Manual sections to `/as:epd-to-spec`.

## Native execution and specification output

This skill is the complete native procedure and has no registered internal operation IDs.
Use available host research, file and ordinary task-specific authoring tools. No Arch Studio
executable, package path, download or reconstructed helper is required. Supplied source content

How to install

The exact contents, by fingerprint

mdr add alpacalabsllc/skills-for-architects/spec-writer@sha256:8a4f054fdf83af0a

The line at the top of this page pins the label git:20260923.ae5849f, 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.
