Practical, no-hype writing on AI agents — cost control, multi-agent architecture, and real-world operations.
Cryptographic audit trail for AI agent governance with verifiable action logs

Cryptographic Audit Trails: Verifiable Action Logs for AI Agents

Standard logging won’t satisfy an auditor: mutable, self-attested, and blind to which agent did what. Here’s the cryptographic audit trail architecture that does.

FrontierCode agent benchmarking infrastructure with code quality evaluation

From SWE-Bench to FrontierCode: The New Agent Code Quality Era

Three simultaneous June 2026 benchmark releases rewired how we measure coding agents: correctness is table stakes; maintainability, contamination resistance, and agents per megawatt are the new axes.

Luminous loop representing harness engineering for long-running coding agents

Harness Engineering: Loops for Long-Running Coding Agents

LangChain tuned only the harness and lifted a coding agent from Top 30 to Top 5 on Terminal Bench 2.0 — no model change required. Here are the loop patterns that make it possible.

Centralized AI agent gateway with data streams connecting to multiple endpoints

The Agent Gateway: Centralized Routing and Cost Control for AI Agents

The agent gateway extends traditional LLM proxies with tool call validation, per-session budget tracking, and autonomy enforcement: the infrastructure that separates production-ready agent systems from expensive experiments.
