Search public agent resources. Returns exact resource ids and canonical browser-openable URLs for citation.

fetch

Fetch the complete public catalog record for an exact resource id returned by search, including a canonical citation URL.

search_harnesses

Search the SuperSkill registry by task, job, title, summary or tag.

harness_detail

Return manifest, trust signals, example and file list for one harness.

search_resources

Search mixed source-aware resources: harnesses, skills, plugins, workflows, MCP servers, configs, guides, runtimes and directories.

resource_detail

Return provenance, trust, popularity and actions for one mixed resource. Pass version to bind a hosted immutable release; latest is never substituted for an explicit version.

resource_use_instructions

Return the best safe next action for a mixed resource. Pass version to bind an immutable hosted release. Hosted skills expose explicit-consent exact native client install commands; upstream-only resources stay open-only.

pull_instructions

Return CLI and HTTP commands for pulling a harness into a local workspace.

pull_harness

Return archive files for a harness. Paid harnesses return payment requirements unless the Bearer token is entitled.

search_docs

Search /llms.txt and agent guidance for API, CLI, MCP and safety instructions.

publish_markdown_to_harness

Convert markdown into an unverified harness scaffold. Requires a SuperSkill Bearer token.

publish_resource_package

Publish an immutable canonical hosted package release. Requires a confirmed-user Bearer with active superskill:managed scope, semantic version and idempotency key. Returns unreviewed trust; never grants a Verified badge.

How we measure →

What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
