Agent Cycle
Claude Code plugin that runs the full construction cycle of an AI agent — from idea to shipped, evaluated, observable production agent — as a gated pipeline of skills.
Overview
A Claude Code plugin that runs the complete construction cycle of an AI agent — from idea to shipped, evaluated, observable production agent — as a gated, disk-backed pipeline of skills. Evals are written before code, artifacts are contracts, humans gate every phase, and "the suite is green" is only ever an exit code.
What it does
- Seven vertical phases in sequence, each gated by an approved artifact: design → spec → evals → build → skills → interop → ship.
- Three horizontal transversals that attach at any point:
review(audit an existing agent),economics(cost, break-even, token-spend alarm),blueprint(one-page client-shareable HTML). - Evals before code: the exam exists, and is red by design, before a single line of the agent is written.
- A re-entry ladder: defects found downstream re-open the lowest phase whose artifact is wrong — the builder never edits evals or specs.
