Make Claude Code hook wiring less invasive and self-contained#15
Merged
Conversation
Drop the PreToolUse hook that spawned a process before every tool call,
and scope PostToolUse to mutating tools (Edit|Write|MultiEdit|
NotebookEdit|Bash) so read-only tools never spawn anything.
Add hooks/hooks.json and a statusLine entry in plugin.json so the
marketplace plugin auto-wires hooks and the statusline via
${CLAUDE_PLUGIN_ROOT}, with no manual settings.json editing.

What
Reduces the Claude Code adapter's footprint and makes the marketplace plugin wire itself with no manual
settings.jsonediting.Why
The adapter wired four hooks, two with
matcher: "*":PreToolUse/*spawnedbunbefore every tool call (Read, Grep, Glob, everything) just to set a "thinking" state — latency on every tool, for a mood the post-action states already cover.PostToolUse/*spawnedbunafter every tool, including read-only ones that don't change the pet's mood.Changes
PreToolUseand deletedhooks/pre-tool-use.sh. (Thethinkingevent stays incore/events.ts— the Pi adapter still emits it.)PostToolUsefrom"*"to"Edit|Write|MultiEdit|NotebookEdit|Bash", so read-only tools never spawn a process.hooks/hooks.jsonso/plugin install campyauto-wires the three lean hooks (SessionStart, scopedPostToolUse,Stop) via${CLAUDE_PLUGIN_ROOT}.statusLineblock toplugin.jsonso the statusline is plugin-provided too.CLAUDE.mdto match.Net: 4 hooks → 3, the only per-tool hook fires on mutating tools instead of everything, and the marketplace install is self-contained.
