ee1df22 narrowed the Claude Code search-guard matcher from "Glob|Grep" to
"Bash" on the premise that dedicated search tools were removed and searches
go through Bash. Current Claude Code routes content search through its
first-class Grep tool (its Bash tool description actively steers away from
shell grep), so the graphify-first nudge never fired on the agent's primary
exploration path and the graph was silently bypassed.
Three-part fix, per the issue's analysis:
- Matcher: "Bash" -> "Bash|Grep" in _claude_pretooluse_hooks. Glob already
fires the read nudge via "Read|Glob", so Grep was the only orphaned tool.
- Guard body: the hook-guard search branch only inspected tool_input.command,
which a Grep call doesn't carry (it has pattern/path/glob). A Grep-shaped
input (pattern present, no command) is now treated as a search — it IS one
by definition — and nudges whenever a fresh graph exists. The Bash
token-matching path is unchanged, and a command-carrying input never
triggers the Grep shape, so non-search Bash calls stay silent.
- Idempotency: "Bash|Grep" added to the four install/uninstall dedup filters
(claude + codebuddy), so upgrading replaces the stale "Bash" hook in place
instead of appending a duplicate — verified against a pre-fix settings.json.
Tests: new regression tests feed Grep-shaped tool_input through
hook-guard search and assert the nudge (with graph), silence (without),
valid PreToolUse JSON, and no blocking; plus a guard that a non-search Bash
command with a stray pattern key does not nudge. Existing matcher assertions
updated across test_search_hook/test_install/test_claude_md/test_codebuddy/
test_hook_strict. Hook+install suites: 397 passed. Full suite: 3224 passed;
the 13 failures are pre-existing on clean v8 in this environment.
Fixes#1986
