+## AI Assistant Tools
+
+### Zen MCP Tools (Use Throughout Every Session)
+- **Zen Debug**: Use whenever you encounter an error or unexpected behavior
+- **Zen Code Review**: Use whenever you finish a significant piece of code or feature
+- **Zen Analyze**: Use before adding new features or making significant changes to existing code
+- **Zen Deepthink**: Use when you have a complex problem to solve or need to brainstorm ideas
+- **Zen Chat**: Use for general questions, clarifications, or when you need assistance with a task
+
+**Important Context Reminder**: Remind the Zen tools that this is a small local environment with a single user, so security and scalability are not primary concerns.
+
+### Clink Multi-Model Workflows (GPT-5, Gemini 3, Kimi K2.5)
+
+Use `mcp__zen__clink` to get diverse AI perspectives via external CLIs. Available CLIs:
+- **codex**: GPT-5 - Fast, precise code understanding
+- **gemini**: Gemini 3 - Large context (1M tokens), thorough analysis
+- **Kimi K2.5** (via `mcp__zen__chat` with OpenRouter) - Strong reasoning, excellent at complex logic
+
+**Security Warning:** Files are sent to OpenAI, Google, and Moonshot AI. NEVER use on `.env`, credentials, or regulated data.
+
+**When to Use Multi-Model:**
+- Code reviews (catch different types of issues)
+- Complex debugging (multiple hypotheses)
+- Architecture decisions (diverse perspectives)
+- Planning (compare approaches)
+
+**Available Skills:**
+- `/multi-review <files>` - Code review from all 3 models
+- `/multi-plan <task>` - Planning perspectives from all 3 models
+- `/multi-debug <issue>` - Parallel bug investigation
+- `/multi-analyze <files>` - Comprehensive analysis
+
+**Quick Usage** (all three calls in one message = parallel execution):
+```python
+review_prompt = "Review for bugs and security issues"
+mcp__zen__clink(prompt=review_prompt, cli_name="codex", role="codereviewer", absolute_file_paths=["/absolute/path/file.py"])
+mcp__zen__clink(prompt=review_prompt, cli_name="gemini", role="codereviewer", absolute_file_paths=["/absolute/path/file.py"])
+mcp__zen__chat(prompt=review_prompt + " Use Kimi K2.5 via OpenRouter for this analysis.", absolute_file_paths=["/absolute/path/file.py"])
+```
+
+**Important:** Use absolute paths (not globs). Resolve patterns first: `find src -name "*.py" | xargs realpath`
+
+**Synthesis Format:** After multi-model analysis, report:
+1. **Consensus** - All models agree
+2. **Majority** - 2/3 agree (note dissent)
+3. **Unique insights** - Model-specific findings
+4. **Recommended actions** - Prioritized by consensus
+
+**Roles:** Each CLI supports `default`, `codereviewer`, `planner`

+
+### Status: COMPLETE - Deployed to Production
+
+**Objective:** Add Slack notifications for trainer registrations, ticket purchases, and event submissions/publishes via Incoming Webhook with Block Kit rich formatting.
+
+### Features
+- **New Trainer Registration** — name, role, organization, business type, profile photo, "View in WordPress" button
+- **Ticket Purchase** — purchaser, email, event, ticket count, total, payment gateway, "View Order" button
+- **Event Submitted by Trainer** — event title, trainer, date, venue, "View Event" button
+- **Event Published by Admin** — same fields, "View Event" + "Edit in WP" buttons
+- **Settings UI** — Webhook URL field (password type), "Send Test Notification" button with AJAX feedback
+- **Test message** includes environment (Staging/Production) and site URL
+
+### Design Decisions
+- Non-blocking `wp_remote_post` for all real notifications; blocking only for test button
+- Atomic `add_post_meta(..., true)` for idempotency (prevents races and duplicate sends)
+- Webhook URL validated at save-time and send-time: `https` + `hooks.slack.com` + `/services/` path
+- Graceful degradation: empty webhook = disabled, missing meta = "N/A" fields, no exceptions surface to users
+- Code reviewed by GPT-5 (Codex) — all 5 findings fixed before production deploy
+
+### Files Modified
+
+| File | Change |
+|------|--------|
+| `includes/class-hvac-slack-notifications.php` | **NEW** — static utility class with 4 notification types + test handler |
+| `includes/class-hvac-settings.php` | Slack webhook URL setting + validation + test button |
+| `includes/class-hvac-plugin.php` | Include file + `init()` call in `initializeSecondaryComponents()` |
+| `includes/class-hvac-registration.php` | One-line call to `notify_new_registration()` after admin email |
