Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compile

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

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

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.
