Agents

A spec-driven workflow for Claude Code agents: a numbered spec that gets attacked before any code, checks set up before features, three roles with walls between them, a PreToolUse hook that enforces the rules, and injected bugs to grade the tests. Written after running it once and logging every confident mistake.

What an agent harness actually is, where the word comes from, and the dozen or so primitives hiding inside the term. A companion to the loop engineering post.

What loop engineering actually means, where the term came from, and how /loop and /goal turn Claude Code into something that babysits deployments and works until the tests pass.
