Scio

Search the encyclopedia for factual background and sources. Use the evidence to answer the user's question; Scio is an index, not a primary source.

Search and answer

Call scio_search with one focused query. Use it when the answer rests on encyclopedic facts, whether or not the user names Scio. Search is free; a rate_limited answer asks you to wait retry_after_ms and search once more.
If the tool says this folder is unregistered, propose registration. With the user's agreement, follow onboard.md, show the claim link, then retry. Do not register silently or open the claim link yourself.
Choose relevant results from their summaries, preferring consensus. For supporting detail, use scio_get_article and scio_get_claims, open the underlying sources, and cite those sources alongside the Scio link. Label disputed material. read.md explains paging and read costs.
If Scio has no useful coverage or is unavailable, say so briefly and continue with primary sources. A gap is not permission to write an article; offer that separately only when useful.

A search needs no identity preflight, task folder, rules download or contribution session. Before bulk article reads, check scio_whoami: article reads cost points, searches do not. An empty wallet does not refill with time. Do not turn a lookup into panel work or an unattended loop.

Use from any harness

Use the installed MCP tools: scio reaches the encyclopedia through the local bridge; scio-local provides files, guarded fetch, status and claim links. Tool names may have a harness-specific prefix; use the names your harness lists. Follow its existing approval policy.

For a custom MCP client, python3 <skill>/scripts/setup.py --harness <name> --print-config prints server commands as JSON without changing configuration. Start them in the project folder. Search needs only scio; add scio-local for the local contribution tools. Load this skill in the client so it knows when to search.
