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 (3)

`compile_handoff`	Compile source-agent outputs into a receiver-ready handoff package. The input schema declares the exact source-output, receiver-contract, and handoff-context fields. The tool selects and validates required deliverables and returns either a portable package or actionable unmet requirements.
`inspect_handoff`	Inspect a handoff package and return an acceptance decision. The tool recalculates deliverable hashes, checks expiry and contract satisfaction, and returns the receiving agent's next action.
`prepare_artifact`	Prepare content for transfer to another agent or a human reviewer. `target_modes` accepts either a JSON list or an actual list of MIME types. The result includes expiring artifact URLs, SHA-256 hashes, a manifest, and a downloadable ZIP package.

Schemas: list_tools.
