Hook results spread the typed result from beneath, element props accept an
explicit undefined as a JavaScript mod passes it, the band's registry
payload is narrowed by assertion, and the example wrappers join the Host
typecheck project.
A Client package mounts the bridge's Remote contribution, watches each
session's band through watchBand, draws the serialized tree in the input
dock with Claude Code's Box/Text/Button vocabulary on this theme's tokens,
and sends button clicks back through pressBand with the generation they
were drawn in. An opt-in overlay composes the bridge, the band, and the
three example mods for a source launch.
A mod is now a plugin built with defineMod() around its register(on,
options); the bridge is the ClaudeCodeMods service (ctx.claudeCodeMods)
that keeps the loaded mods and raises their events. The plugin.json /
hooks.json loader, pluginDirs, and dynamic imports are gone.
prompt.submit context becomes text blocks appended to the human's own
prompt message and $.prompt.submit queues a user-sourced message, so the
bridge adds no message source kind: the persistence record and the
regenerated schema are removed and the artifacts match master again.
Engine correctness from the review round: next() is memoized and every
started run beneath is awaited before a hook's answer settles; a rewritten
tool argument skips the hook with a report pointing at the pre-tool input
rewrite proposal; timers belong to the session whose event started them;
$.tool.call injects a tool's deferred contexts; $.clock.sleep honors the
event signal; a built-in tool answered with { result } is validated against
its output schema before it becomes an error-shaped result; hooks on events
this host never raises are reported at load.
Examples: the three mods from the Claude Code blog post under examples/,
Token Weather and its test unchanged, Blast Radius and Replay Theater
completed from the published fragments, run by their own tests through a
claude-code/testing alias over the new test kit ($.ui.mount/find/press).
