Declared Tools

A minimal example demonstrating the ### Tools section: how a .prose.md component declares which host CLI executables it requires the host environment to provide.

The component in src/json-verifier.prose.md declares cli:jq as a required host tool. When prose compile is run against this directory, the compiler's tools_resolver checks for a jq executable on PATH and fails closed with tool_unresolved if it is not available.

See skills/open-prose/contract-markdown.md (Tools) and skills/open-prose/compiler/index.prose.md (tools_resolver) for the full specification.

Run it

prose compile

This is a lone kind: function contract, so there is nothing to serve: the compile either resolves the declared tool or fails closed with tool_unresolved.
