Permissions Are Part of Agent Architecture
Secure agent systems constrain blast radius with scoped identities, narrow tools, data boundaries, meaningful approvals, and a tested way to revoke access.
How to Know When a Coding Agent Has Gone Rogue
Agent observability should connect intent, tool calls, state changes, verification, cost, and policy into one trace an operator can actually debug.
Long-Running Codex Tasks Need a Runtime, Not a Longer Prompt
How to design Codex work that can run unattended, recover safely, and return evidence instead of an unfinished transcript.
Measuring Whether Coding Agents Are Actually Working
Measure accepted outcomes, cycle time, quality, review burden, and total cost together instead of mistaking usage or code volume for value.
Parallel Agents Need Isolation, Not Just More Agents
A field guide to deciding what should run in parallel, isolating writes, and designing handoffs that are cheaper to verify than to redo.
The Harness Is the Product
A production coding agent is the model plus everything that makes its work bounded, repeatable, testable, and safe.
Verification Is the Real Agent Loop
A practical validation stack for coding agents, from cheap deterministic checks to behavioral tests, graders, and human review.
