+# Codebase Integrations (`INTEGRATIONS.md`)
+
+## Webhooks & APIs
+- Currently, this project relies purely on Git synchronisation and CLI execution. Network activity is limited to downloading external packages (`npm install`, `pip install`, `git clone/pull`).
+- Once MCP tools are invoked, `claude-mem` likely interacts with SQLite logic or LLM memory endpoints depending on its runtime schema. `browser-use` interfaces with web targets directly.
+
+## Databases & Persistence
+- There are no central RDBMS or NoSQL layers native to this orchestration layer.
+- **Knowledge/Memory**: The project serves as an SSOT using markdown (`.planning/*`, `.agent/knowledge/*`).
+- **MCP state persistence**: Relies on specific plugin's local DBs (e.g., SQLite for mem logs).
+
+## Third-Party Authentication
+- Configured by `.agent/config/.env.agent` which includes API keys (Vikunja Task ID, Gitea instances, etc.), though the current codebase only seeds and checks for its existence without directly invoking the APIs inside the shell scripts.
+
+## Core External Tools
+- **Git**: Primary persistence and vendor orchestration transport mechanism.
+- **NPM & PIP**: Invoked asynchronously by bootstrap scripts to satisfy AI tool dependencies.
