+## AI Mate Agent Instructions
+
+This MCP server provides specialized tools for PHP development.
+The following extensions are installed and provide MCP tools that you should
+prefer over running CLI commands directly.
+
+---
+
+### Monolog Bridge
+
+Use MCP tools instead of CLI for log analysis:
+
+| Instead of...                     | Use                                |
+|-----------------------------------|------------------------------------|
+| `tail -f var/log/dev.log`         | `monolog-tail`                     |
+| `grep "error" var/log/*.log`      | `monolog-search` with term "error" |
+| `grep -E "pattern" var/log/*.log` | `monolog-search-regex`             |
+
+#### Benefits
+
+- Structured output with parsed log entries
+- Multi-file search across all logs at once
+- Filter by environment, level, or channel
+
+---
+
+### Symfony Bridge
+
+#### Container Introspection
+
+| Instead of...                  | Use                 |
+|--------------------------------|---------------------|
+| `bin/console debug:container`  | `symfony-services`  |
+
+- Direct access to compiled container
+- Environment-aware (auto-detects dev/test/prod)
+
+#### Profiler Access
+
+When `symfony/http-kernel` is installed, profiler tools become available:
+
+| Tool                        | Description                                |
+|-----------------------------|--------------------------------------------|
+| `symfony-profiler-list`     | List profiles with optional filtering      |
+| `symfony-profiler-latest`   | Get the most recent profile                |
+| `symfony-profiler-search`   | Search by route, method, status, date      |
+| `symfony-profiler-get`      | Get profile by token                       |
+
+**Resources:**
+- `symfony-profiler://profile/{token}` - Full profile with collector list
+- `symfony-profiler://profile/{token}/{collector}` - Collector-specific data
+
+**Security:** Cookies, session data, auth headers, and sensitive env vars are automatically redacted.
