Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (12)

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