+# MCP Tools Skill (Optional)
+
+If this repo defines MCP servers/tools:
+
+Rules:
+- Tool calls must be explicit and logged.
+- Maintain an allowlist of tools; deny by default.
+- Every tool must have: purpose, inputs/outputs schema, examples, and tests.
+- Prefer idempotent tool operations.
+- Never add tools that can exfiltrate secrets without strict guards.
