Closed-loop feature documentation for your product. Give it a feature (issue numbers or an id) and it reads the source, drives your live app to capture real screenshots and a screen recording, writes a docs article (Docusaurus or any markdown docs site) with both how-to steps and use-case content, then verifies the article with a fresh-context read-only verifier before reporting. Use when you say "write the doc for <feature>", "document issue #123", or "/feature-doc".

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

# feature-doc: closed-loop feature documentation

Produces one evidence-backed feature article end to end. Capture needs no manual
gesture: a bundled recorder grabs frames from the browser through the DevTools
protocol. Publishing the docs PR stays a gate for you at CP-6.

## Configuration

Set these once (a `.env`, your `kit.toml`, or pass them as arguments). Nothing below is hardcoded.

| Setting | Meaning | Example |
|---|---|---|
| `APP_URL` | Start page of the live app to drive | `https://app.example.com/projects/1` |
| `ISSUE_REPO` | Issue tracker holding the feature issues | `your-org/your-product` |
| `DOCS_REPO` | Local path of the docs repo | `../your-docs` |
| `DOCS_DIR` | Folder inside the docs repo for the article | `docs/features/` |
| `EVIDENCE_DIR` | Where screenshots and video land | `./evidence/<feature>/` |

Keep the docs repo in a folder your tools can always read. Some operating systems block background reads of the Documents folder mid-session, which breaks the verifier.

## When to use
- A shipped or shipping feature has no article, or an outdated one.

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/feature-doc@sha256:b90a8bd3487924a2

The line at the top of this page pins the label git:20261023.65f43f1, 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.
