docs: Add Cisco AI Defense integration

Integration: Cisco AI Defense Plugin for Google ADK

What it does

Cisco AI Defense is a Google ADK plugin that integrates runtime LLM and MCP tool inspection directly into the ADK Runner lifecycle using a BasePlugin and per-agent callbacks.

It inspects user prompts before model calls, model outputs after generation, and MCP tool call requests/responses — then allows or blocks based on configurable security policies. No monkey-patching required.

Key capabilities

• Runtime protection for Gemini calls: Inspect user prompts before model calls and model outputs after generation, then allow or block based on policy (Monitor or Enforce).
• Tool and MCP call inspection: Inspect tool call requests before execution and tool responses after execution, and block unsafe tool behavior in Enforce mode with clear metadata.
• Auditable decision trace and alerts: Capture decision context (action, severity, classifications, request_id/event_id) and optionally trigger an on_violation callback for monitoring and incident response.

Integration type

• Plugin (BasePlugin subclass) — global, applies to all agents in the Runner
• Agent callbacks — per-agent, wired via before_model_callback, after_model_callback, before_tool_callback, after_tool_callback

Installation

pip install cisco-aidefense-google-adk

Proposed documentation

I'd like to add an integration page at docs/integrations/cisco-ai-defense.md following the integration contribution template, including:

• Frontmatter with catalog metadata
• Use cases, prerequisites, installation
• Working code examples (plugin and callback approaches)
• Modes table (monitor / enforce / off)
• Callbacks covered table
• Resource links

A logo asset will be included at docs/integrations/assets/cisco-ai-defense.png.

I will follow up with a PR once this issue is acknowledged.

Thanks for the issue and proposal. We can add this to the integrations catalog, pending review of the final form and PR. You can follow the patterns and style of existing integration pages for reference.
