## Tools (12)

- `fetch`: Fetch the complete public catalog record for an exact resource id returned by search, including a canonical citation URL.
- `harness_detail`: Return manifest, trust signals, example and file list for one harness.
- `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.
- `pull_harness`: Return archive files for a harness. Paid harnesses return payment requirements unless the Bearer token is entitled.
- `pull_instructions`: Return CLI and HTTP commands for pulling a harness into a local workspace.
- `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.
- `search`: Search public agent resources. Returns exact resource ids and canonical browser-openable URLs for citation.
- `search_docs`: Search /llms.txt and agent guidance for API, CLI, MCP and safety instructions.
- `search_harnesses`: Search the SuperSkill registry by task, job, title, summary or tag.
- `search_resources`: Search mixed source-aware resources: harnesses, skills, plugins, workflows, MCP servers, configs, guides, runtimes and directories.
