ai:agent

A measurement-first decision discipline for choosing HOW to build something. Before pouring effort into one approach, operationalize a measurable fitness, sketch a few candidate directions, cheaply score each by that fitness, and pick the winner by the number — not by taste, and not by polish. Lightweight and inline: it is a discipline, not a multi-agent engine. Manually triggered via `/anneal` only — never auto-invoked. Use when the user types `/anneal`, typically at a fork where the best approach is not obvious.

About this skill (catalog notes)

From the source SKILL.md

A lightweight discipline: at a fork, explore a few directions and let a cheap measurement pick the winner, before you invest in the expensive build. Named for simulated annealing (explore, then converge) — but it is a checklist you run inline, not an engine you launch.

What this skill does

When to invoke it: Use when the user types `/anneal`, typically at a fork where the best approach is not obvious.
