README

Excerpt

182 — ask-dev3 feature-router skill

Context

Users (and the agents serving them) don't remember every dev3 feature or the intended way to use it. We wanted a skill, modeled on Matt Pocock's ask-matt router, that answers "how is X done in dev3?" by teaching the intended flow instead of guessing. It ships to every dev3 install like the other managed skills.

Decision

Added ask-dev3 as an auto-installed agent skill (ASK_DEV3_SKILL_CONTENT in src/bun/agent-skills.ts, written into .claude/.cursor/.agents/.codex/.opencode skill dirs on startup, with an openai.yaml interface stub — same pattern as dev3-bug-hunter). Shape decided in a grilling session:
