Engineering: Tools, Review, Verification, Security, and Observability¶
The engineering disciplines that turn agent prototypes into production systems — tool design, code review, verification, security hardening, and observability.
The engineering disciplines that make agent systems production-ready — from tool design and code review to verification, security, and observability.
Tool Engineering¶
Design, implement, and optimize the tools agents use — MCP servers, CLI wrappers, hook lifecycles, skill authoring, and token-efficient tool interfaces.
Code Review¶
Patterns for reviewing agent-generated code — tiered review strategies, diff-based approaches, committee patterns, and balancing PR volume against value.
Verification¶
Testing and validation strategies for agent output — TDD workflows, pass@k metrics, deterministic guardrails, behavioral testing, and trajectory analysis.
Security¶
Hardening agent systems against prompt injection, credential leakage, tool-invocation attacks, and other threats — defense-in-depth, sandboxing, and permission gating.
Observability¶
Monitoring and debugging agent behavior — OpenTelemetry integration, trajectory logging, circuit breakers, loop detection, and making observability legible to agents themselves.
