verify SKILL.md skillC
verify from derive-to/derive is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add derive-to/derive/verify@git:20260711.626e544Pins git:20260711.626e544 in mdr.lock. Pin the fingerprint instead.

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
# verify (local runtime for apps/api)
Run the real Node server against a throwaway SQLite to observe API behavior end-to-end
(no Docker needed — faster than `deploy/compose.yml` for a verification loop):
```bash
DATA_DIR=<scratch-dir> PORT=8791 DERIVE_TOKEN=devtok BASE_URL=http://localhost:8791 \
pnpm --filter @derive/api exec tsx src/node.ts
```
- Health: `curl localhost:8791/healthz` → `{"ok":true}`. The boot log's `meta:` line names
the exact SQLite path — always confirm it's your scratch dir, never a remote DB.
- Publish via HTTP: `curl -X POST localhost:8791/v1/artifacts -H "authorization: Bearer devtok" -F 'file=@-;filename=index.html;type=text/html' -F 'title=T' <<< '<h1>x</h1>'`
- Preview screenshots: add `DERIVE_PREVIEWS=true` (needs Playwright Chromium — usually
already in `~/Library/Caches/ms-playwright`; else `pnpm --filter @derive/api exec playwright install chromium`).
The worker ticks every 1.5s; `/v1/og/<short_id>` flips from SVG fallback to PNG when the
render lands. `version.preview_status` / `render_job` in the scratch `derive.db` show pipeline state.
- The bundled SPA serves at `/` but needs a signup; API-level checks (`/v1/artifacts`,

How to install
mdr add derive-to/derive/verify@sha256:5ac91c18bfc8a1c6The line at the top of this page pins the label git:20260711.626e544, 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.
