Agent-to-Agent Handoffs: Designing Interoperable AI Systems
Connecting heterogeneous AI agents across departmental boundaries requires formal interoperability standards. Learn how to architect Agent-to-Agent (A2A) handoffs using mutual cryptographic authentication, signed capability contracts, state isolation, and deadlock prevention watchdogs.
The Enterprise Agent Gateway: Identity, Policy and Tool Access
Allowing autonomous agents to connect directly to internal microservices introduces critical security vulnerabilities. An enterprise Agent Gateway acts as an intelligent reverse proxy enforcing Non-Human Identity (NHI) authentication, granular RBAC policies, token rate limits, and egress DLP scanning.
Building an Internal Tool Catalog for AI Agents
As enterprise teams deploy dozens of specialized MCP tool servers, AI agents need a discoverable, versioned tool registry. Learn how to architect an internal tool catalog featuring semantic vector search over tool descriptions, automated schema testing, and live health checks.
Why Agent Tool Contracts Need Structured Schemas
Allowing language models to pass unstructured strings or loosely-typed dictionaries to backend tools leads to hallucinated keys, silent data corruption, and catastrophic runtime parsing errors. Strict Pydantic and JSON Schema contracts with static type validation are mandatory for reliable agent execution.
Designing Durable Tasks for Agent Infrastructure
Autonomous agent workflows frequently span minutes or hours across complex multi-step execution graphs. Learn how to architect durable task engines using event-sourced state machines, write-ahead logs (WAL), and idempotent retry policies to ensure agents survive pod evictions and network partitions without losing progress.
The Agent Identity Problem: AI Workers Need Their Own Authorization Model
Treating AI agents as either static service accounts or cloned human users creates dangerous security blindspots. Autonomous AI workers require dedicated Non-Human Identity (NHI) models, ephemeral JWT delegation chains, and fine-grained authorization per task.
Least Privilege for AI Agents: Scoping Tools and Ephemeral Permissions
Granting static, broad permissions to autonomous AI agents creates extreme security blast radiuses. Ephemeral permissions that dynamically narrow based on the specific approved task envelope are the only reliable defense against autonomous privilege escalation.
How to Audit What an AI Agent Actually Did
Traditional web server access logs fail to capture why an autonomous agent made a decision or what data influenced its reasoning. Building compliance-grade auditability requires immutable cryptographic ledgers, prompt-context snapshots, parameter diffs, and non-repudiation seals.
Agent Observability: What Should You Actually Measure?
Monitoring autonomous AI agents requires metrics far beyond basic token counts and HTTP response codes. Building comprehensive agent observability means instrumenting OpenTelemetry spans to measure plan drift, recursive tool retry loops, context window saturation, and dollar cost per completed task.
Designing Kill Switches and Intervention Controls for Autonomous Agents
When an autonomous AI agent enters a recursive loop or exhibits plan drift, pulling the plug requires more than terminating a Docker container. Learn how to architect multi-stage intervention controls, read-only quarantine modes, and sub-5ms cryptographic token revocation.
