+# Claude Code × OpenViking Memory Hooks
+
+Auto-extract memories from [Claude Code](https://docs.anthropic.com/en/docs/claude-code) sessions into OpenViking using [Claude Code hooks](https://docs.anthropic.com/en/docs/claude-code/hooks).
+
+## How It Works
+
+Three hooks capture conversation transcripts at strategic lifecycle points and pipe them into OpenViking's memory system:
+
+| Hook | Trigger | What it does |
+|------|---------|--------------|
+| `SubagentStop` | A subagent finishes | Extracts the subagent's transcript and saves it as a memory |
+| `PreCompact` | Before context compaction | Snapshots the conversation before details are summarized away |
+| `SessionEnd` | Session terminates | Archives the full session via structured `ov session` workflow |
+
+```
+Claude Code Session
+       │
+       ├── SubagentStop ──→ ov add-memory <messages>
+       │
+       ├── PreCompact ────→ ov add-memory <messages>
+       │
+       └── SessionEnd ────→ ov session new
+                              → ov session add-message × N
+                              → ov session commit
+```
+
+`SubagentStop` and `PreCompact` use `ov add-memory`, which accepts a batch of messages in a single call — ideal when you already have the full transcript in hand and want to minimize client-server round trips.
+
+`SessionEnd` uses `ov session add-message` per message, then commits at the end. This is intentionally kept as a reference pattern: if you integrate hooks that fire incrementally (e.g. `UserPromptSubmit` or `Stop`), you'd call `ov session add-message` after each turn to build up the session over time — without committing on the spot — and only commit when the session is complete.
+
+All hooks run **async** (non-blocking) and the slow LLM extraction step runs in a `nohup` background process so it never delays Claude's responses.
+
+## How Claude Code Hooks Work
+
+When a hook event fires, Claude Code runs the registered shell command and passes event data as **JSON via stdin**. Every hook receives a common base payload plus event-specific fields:
+
+```json
+{
+  "hook_event_name": "SubagentStop",
+  "session_id": "abc123",
+  "transcript_path": "/path/to/transcript.jsonl",
+  "cwd": "/Users/you/project",
+  "permission_mode": "default",
+  "agent_type": "general-purpose",
+  "agent_transcript_path": "/path/to/subagent.jsonl"
+}
+```
+
+Hook scripts read this with `INPUT=$(cat)` and parse fields with `jq`. See [Hooks.md](./Hooks.md) for all events and their unique params.
+
+Exit codes control behavior for blocking hooks — exit `0` to allow, `1` to block, `2` to request user confirmation. Hooks registered with `"async": true` (like these) run in the background and their exit code is ignored.
+
+## Prerequisites
+
+- [Claude Code](https://docs.anthropic.com/en/docs/claude-code) installed
+- [OpenViking CLI](../../README.md) configured (`~/.openviking/ovcli.conf`)
+- `jq` installed (`brew install jq` / `apt install jq`)
+- `python3` available (used for unicode-safe content truncation in logs)
+
+## Setup
+
+### 1. Copy hooks
+
+```bash
+mkdir -p ~/.claude/hooks
+cp hooks/*.sh ~/.claude/hooks/
+chmod +x ~/.claude/hooks/*.sh
+```
+
+### 2. Register in Claude Code settings
+
+Add to `~/.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "SubagentStop": [
+      {
+        "hooks": [
+          { "type": "command", "command": "$HOME/.claude/hooks/ov-memory-subagent-stop.sh", "async": true }
+        ]
+      }
+    ],
+    "PreCompact": [
+      {
+        "hooks": [
+          { "type": "command", "command": "$HOME/.claude/hooks/ov-memory-pre-compact.sh", "async": true }
+        ]
+      }
+    ],
+    "SessionEnd": [
+      {
+        "hooks": [
+          { "type": "command", "command": "$HOME/.claude/hooks/ov-memory-session-end.sh", "async": true }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### 3. Verify
+
+```bash
+claude
+/hooks
+```
+
+## Debugging
+
+Set `OV_HOOK_DEBUG=1` to enable logging to `/tmp/ov.log`:
+
+```bash
+export OV_HOOK_DEBUG=1
+claude
+```
+
+Then watch the log in another terminal:
+
+```bash
+tail -f /tmp/ov.log
+```
+
+Log output uses color — gray timestamps, purple `ov` commands — and message content is truncated to 120 characters for readability. The actual data sent to OpenViking is always the full untruncated content.
+
+Example output:
+
+```
+[2026-02-22 10:00:01] SubagentStop: queued 4 msgs from general-purpose
+2026-02-22 10:00:01  ov add-memory '[{"role":"user","content":"You are a senior backend engineer..."},...]'
+[2026-02-22 10:00:03] SubagentStop: saved 4 msgs from general-purpose
+
+[2026-02-22 10:30:00] SessionEnd: queued commit 56 msgs (ov=abc123, reason=other)
+2026-02-22 10:30:00  ov session new -o json -c
+2026-02-22 10:30:00  ov session add-message --role 'user' --content 'what hooks do you have now' abc123
+2026-02-22 10:30:00  ov session commit abc123
+```
+
+## Verifying Memories
+
+After hooks fire, check what was extracted:
+
+```bash
+ov search "what did I work on today"
+```
+
+## Extending to Other Hooks
+
+See [Hooks.md](./Hooks.md) for a quick reference of all 17 Claude Code hook events and the params each provides via stdin. Useful starting points for extending this example:
+
+- `UserPromptSubmit` — add a message to an open `ov session` on every user turn
+- `Stop` — commit the session when Claude finishes responding (pairs with `UserPromptSubmit`)
+- `PostToolUse` — capture tool results alongside conversation turns
+
+## Customization
+
+- **Skip short sessions**: Add a `$COUNT` threshold check before running `ov` commands
+- **Change log file**: Edit `LOG=` in each script (only matters when `OV_HOOK_DEBUG=1`)
+- **Add project tags**: Pass metadata via `ov session` flags
