What's new

feat(hooks): structured telemetry table + icm hook-log / icm hook-stats (#222)

Adds a hook_events table that captures every icm hook <event> invocation (start | end | pre | post | prompt | compact) with timestamp, duration, exit code, and an optional error note.

Two new CLI commands:

• icm hook-log [--limit N] [--event NAME] [--prune-older-than RFC3339] — recent rows
• icm hook-stats [--since-hours N] — per-event count, error rate, avg/p50/p99 latency

Why

Claude Code does not log SessionEnd attachments to its session JSONL, so confirming that icm hook end actually fired previously required catching the detached worker mid-run via ps. This table makes every hook fire observable from inside ICM itself.

Example

$ icm hook-stats --since-hours 24
event      count  errors    avg ms    p50 ms    p99 ms
end           42       0      11.3         9        38
post         756       0      14.1        13        27
start          8       0      35.0        36        83

Features

Async LLM-CLI extraction path (#219)

Adds an opt-in fast path that removes the ~3.7s fastembed model-load tax on PostToolUse + SessionEnd hooks. When configured, hooks enqueue raw output in ~10ms and a worker drains the queue via the user's existing LLM CLI (claude/codex/gemini/ollama).

```toml

~/.config/icm/config.toml

[extraction.summarizer]
provider = "auto" # auto | none | claude | codex | gemini | ollama
model = "claude-haiku-4-5"
max_tokens = 400
timeout_secs = 30
```

Mode	Hook latency	Quality	Cost
`provider = "none"` (default)	3.7s	OK (anchor)	$0
`provider = "auto"` (new)	~10ms	Excellent (LLM)	$0 (user subscription)

The default `none` keeps the inline fastembed path untouched — zero regression for existing users.

What's new

• `[extraction.summarizer]` config block
• `pending_extractions` queue table (idempotent migration)
• `icm extract-pending [--limit N --provider X --model M --dry-run]` worker command
• SessionEnd hook forks the worker via `setsid` on Unix when provider is configured — no more "Hook cancelled" timeouts from Claude Code

Live verification

```
Hook fire latency: 10ms (was 3700ms inline)
SessionEnd: no "Hook cancelled" anymore
Worker: claude CLI extracted clean bullet, stored as Memory
441 tests pass on Linux/macOS/Windows
```

Bug Fixes

CRITICAL follow-up (completes 0.10.46)

• hook: extract output from per-tool `tool_response` shapes (Bash/Read/Write) (#216)

  0.10.46 fixed the top-level `tool_response.output` reader but Claude Code 2.1.138 doesn't actually emit that field. Each built-in tool nests its content under a tool-specific key:

  Tool	Path
  Bash	`tool_response.stdout`
  Read	`tool_response.file.content`
  Write	`tool_response.content`
  Edit	`tool_response.content`

  Net effect of 0.10.46 alone: extraction still produced zero memories on Read/Write/Edit and only matched Bash on clients that emitted `output` instead of `stdout`. 0.10.47 is the release that actually delivers what 0.10.46 promised.

Verified

• 11 regression tests on `extract_tool_output` covering 6 payload shapes
• 3 byte-for-byte fixtures captured via tap script during a real `claude -p` smoke test
• Live end-to-end: `Newest` advanced 17:13 → 17:27 after a single Bash hook fire on the patched binary; unpatched 0.10.46 produced no extraction on identical input
• 441+ tests pass on Linux / macOS / Windows
• `cargo clippy --all-targets -- -D warnings` clean

Upgrade urgency

If you're running Claude Code 2.x and you upgraded to 0.10.46: upgrade to 0.10.47 now. The 0.10.46 release closed the silent-extraction-failure issue but, as live testing revealed afterward, only partially — Read/Write/Edit hook fires still produced nothing. 0.10.47 closes the remaining gap.

Bug Fixes

CRITICAL

• hook: read Claude Code 2.x `tool_response.output` payload (#212) — closes silent auto-extraction failure on every Claude Code 2.x install. The hook fired, the counter incremented, but the legacy `tool_output` field was empty in the new payload shape, so zero memories were stored despite hours of activity.

  Now accepts three payload shapes (legacy, Claude Code 2.x, Codex variants) with 8 regression tests + 3 byte-for-byte fixtures pinned in `tests/fixtures/hook_payloads/` so the next upstream change breaks at PR review instead of silently in production.

Stability

• init: turn 7 init unwrap panics into proper error returns (#213) — `icm init` no longer hard-panics on malformed user MCP / hook config files. Errors now point at the exact key + path that's wrong.

Verification

• 438+ tests pass on Linux / macOS / Windows
• 8 regression tests + 3 fixture files for hook payload parsing
• Smoke-tested on dev box: 5 hook fires with Claude Code 2.x payload yielded 2 memories at +4min where the unpatched binary produced none on identical input

Upgrade urgency

If you run Claude Code 2.x with ICM hooks installed, upgrade now — auto-extraction has been silently broken since you upgraded Claude Code. Existing memories in your store are unaffected; only new ones since the Claude Code upgrade are missing.

Binary assets are built by the post-release workflow and will appear shortly.
