Research a person''s public track record and give a short credibility assessment. Use only when the user explicitly invokes /who-is-this.
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
# who-is-this Read the `deepapi` skill first. All search and scraping goes through DeepAPI. Never use built-in search, fetch, or a browser. ## Seed Accept a name, handle, URL, or profile screenshot. If missing, ask once; never guess a person. Verify matching bio, company, location, and photo before deeper research. If identity is ambiguous, stop and ask. ## Research Find their X, LinkedIn, and GitHub first (dedicated endpoints, not `site:` search). Then run these in parallel: 1. **GitHub activity.** `POST /v1/scrape/github/profile` with `includeRepos: true`, plus recent PRs (`POST /v1/scrape/github/search`, `type: "pulls"`, `query: "author:<username>"`, `sort: "updated"`). 2. **Last 10 LinkedIn posts.** `POST /v1/scrape/linkedin/posts`, `maxItems: 10`. Also scrape the LinkedIn profile if you have the slug. 3. **Deep research.** `POST /v1/research/deep` on who they are, what they have actually done, and whether the public story holds. 4. **50 newest X posts.** `POST /v1/scrape/twitter/search` with the handle, `sort: "latest"`, `maxItems: 50`. Also pull `POST /v1/scrape/twitter/user`. …

How to install
mdr add davidondrej/skills/who-is-this@sha256:e4ae44bef96114b7The line at the top of this page pins the label git:20260926.7dce66c, 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.
