## The Five Hooks
## The Seven Hook Scripts
### Hook 1: SessionStart (Context Hook)
Claude-Mem uses 7 hook scripts across 5 lifecycle events. SessionStart runs 3 hooks in sequence.
**Purpose:** Inject relevant context from previous sessions
### Hook 1: SessionStart - Smart Install
**When:** Claude Code starts or resumes
**Purpose:** Intelligently manage dependencies and start worker service
**When:** Claude Code starts (startup, clear, or compact)
**What it does:**
1. Extracts project name from current working directory
2. Queries SQLite for recent session summaries (last 10)
3. Queries SQLite for recent observations (last 50)
4. Formats as progressive disclosure index
5. Outputs to stdout (automatically injected into context)
1. Checks if dependencies need installation (version marker)
2. Only runs `npm install` when necessary:
- First-time installation
- Version changed in package.json
- Critical dependency missing (better-sqlite3)
3. Provides Windows-specific error messages
4. Starts PM2 worker service
**Configuration:**
```json
{
"hooks": {
"SessionStart": [{
"matcher": "startup",
"matcher": "startup|clear|compact",
"hooks": [{
"type": "command",
"command": "${CLAUDE_PLUGIN_ROOT}/scripts/context-hook.js",
"timeout": 120
"command": "node \"${CLAUDE_PLUGIN_ROOT}/../scripts/smart-install.js\" && node ${CLAUDE_PLUGIN_ROOT}/scripts/context-hook.js",
"timeout": 300
}]
}]
}
}
```
**Key Features:**
- ✅ Version caching (`.install-version` file)
- ✅ Fast when already installed (~10ms vs 2-5 seconds)
- ✅ Cross-platform compatible
- ✅ Helpful Windows error messages for build tools
**v5.0.3 Enhancement:** Smart caching eliminates redundant installs
**Source:** `scripts/smart-install.js`

### Hook 2: SessionStart - Context Injection
**Purpose:** Inject relevant context from previous sessions
**When:** Claude Code starts (runs after smart-install)
**What it does:**
1. Extracts project name from current working directory
2. Queries SQLite for recent session summaries (last 10)
3. Queries SQLite for recent observations (configurable, default 50)
4. Formats as progressive disclosure index
5. Outputs to stdout (automatically injected into context)
**Key decisions:**
- ✅ Only runs on "startup" (not "clear" or "compact")
- ✅ 120-second timeout for npm install (v4.3.1 fix)
- ✅ Uses `--loglevel=silent` for clean JSON output
- ✅ Runs on startup, clear, and compact
- ✅ 300-second timeout (allows for npm install if needed)
- ✅ Progressive disclosure format (index, not full details)
- ✅ Configurable observation count via `CLAUDE_MEM_CONTEXT_OBSERVATIONS`

### Hook 2: UserPromptSubmit (New Session Hook)
### Hook 3: SessionStart - User Message
**Purpose:** Display helpful user messages during first-time setup
**When:** Claude Code starts (runs after context-hook)
**What it does:**
1. Checks if dependencies are installed
2. Shows first-time setup message if needed
3. Displays formatted context information with colors
4. Shows link to viewer UI (http://localhost:37777)
5. Exits with code 3 (informational, not error)
**Configuration:**
```json
{
"hooks": {
"SessionStart": [{
"matcher": "startup|clear|compact",
"hooks": [{
"type": "command",
"command": "node ${CLAUDE_PLUGIN_ROOT}/scripts/user-message-hook.js",

```
📝 Claude-Mem Context Loaded
ℹ️ Note: This appears as stderr but is informational only
[Context details with colors...]
📺 Watch live in browser http://localhost:37777/ (New! v5.1)

- ✅ User-friendly first-time experience
- ✅ Visual context display
- ✅ Links to viewer UI
- ✅ Non-intrusive (exit code 3)

**Why SessionStart is slower:**
- npm install check (idempotent but runs every time)
- Database query for 10 sessions + 50 observations
- Formatting progressive disclosure index
**Why smart-install is sometimes slow:**
- First-time: Full npm install (2-5 seconds)
- Cached: Version check only (~10ms)
- Version change: Full npm install + PM2 restart
**Optimization (v4.3.1):**
- Use `--loglevel=silent` for npm install
- Cache package.json hash to skip unnecessary installs
- Use prepared statements for database queries
**Optimization (v5.0.3):**
- Version caching with `.install-version` marker
- Only install on version change or missing deps
- Windows-specific error messages with build tool help
