• Agentic Security Checklist · Guide
  Cross-vendor, threat-surface-organized security checklist for building and operating AI agents — synthesizing OWASP, NIST, Anthropic, OpenAI, Google SAIF, and MITRE ATLAS.
• Guardrails and Safety Filters for Agents · Guide
  Runtime input/output/action controls that enforce policy independently of the model — tooling landscape, techniques, and layering guidance.
• Agentic AI Browsers: Comet, Atlas, and the Prompt-Injection Attack Surface · Guide
  What agentic browsers (Perplexity Comet, the now-sunsetting ChatGPT Atlas, Microsoft Edge Copilot Mode, Opera Neon) are, how they differ from developer-facing computer-use APIs, and the documented prompt-injection attacks — CometJacking, indirect injection, hidden-text/screenshot instructions — that target the whole product category.
• Prompt Injection Design Patterns: Architectural Defenses for Agents · Guide
  Six named architectural patterns — Action-Selector, Plan-Then-Execute, LLM Map-Reduce, Dual LLM, Code-Then-Execute, Context-Minimization — plus Google DeepMind's CaMeL, that structurally constrain what an agent can do with untrusted data instead of just filtering it.

• Defending MCP Clients Against Tool Description and Output Injection · guide
  Two distinct MCP injection surfaces — a tool description at connect-time and a tool's return value at call-time — and the client-side architectural patterns (Dual LLM, Action-Selector, Context-Minimization) that contain each one.
