The review-manager: anatomy of a code review orchestrator
A deep dive into the review-manager powering opencode-team-lead — how it selects reviewers, isolates their contexts, arbitrates disagreements, and produces a structured verdict without reading a single line of code.

opencode-team-lead: an agent that plans, delegates, and never writes code
On long tasks, an all-in-one agent loses track and reviews its own code with the same blind spots that produced it. I built opencode-team-lead to fix both problems with a strict delegation pattern.

Harness engineering: what Anthropic and OpenAI are actually doing with their agents
Anthropic and OpenAI published their harness engineering post-mortems weeks apart. Different problems, same conclusions — here's what to take away.
