"""The single source of truth for every surface: plain functions, flat arguments in, JSON-ready dicts out.
The CLI is ``cw`` over :data:`TOOLS`; the MCP server exposes the same functions by
``correspond.tools:<name>`` reference; the shipped skill describes these verbs. Nothing here
knows about any of those surfaces.
Every result carries ``ok`` and a one-line ``summary``; longer human-readable output is in
``text``. A failure the caller can act on (an unknown channel, a malformed reference, an
operation the channel lacks, a platform error) comes back as ``ok: false`` with an
``error_kind``, never as a traceback. Library code that wants model objects uses
:mod:`correspond.ops`.
