A practical guide to caching external tool results for LLM agents, covering idempotent key design, TTL semantics, event-driven invalidation, state isolation, audit replay, and a pre-launch checklist to reduce API costs and latency while avoiding cache pollution and cross-tenant leaks.
A systematic guide to contract testing for LLM Agent tool calls, covering function schema versioning, compatibility rules, contract case design, replay testing, CI gating, and release checklists to help engineering teams surface schema evolution risks early.
A systematic guide to caching tool call results in LLM agents, covering cache key design, TTL, idempotency, invalidation, observability, and production checklists to reduce external API costs and tail latency while maintaining accuracy.
A systematic guide to securing LLM Agent tool calls against Prompt Injection, Tool Poisoning, and privilege escalation. Covers trust boundaries, permission boundaries, and execution boundaries with practical implementations including policy gates, human approval, sandboxing, and full-stack monitoring.
MCP standardizes LLM-tool connections but amplifies risks in permissions, identity, audit, and prompt injection. This post presents a practical security governance framework covering protocol boundaries, authorization models, execution isolation, and deployment checks.
