Individual skill

asdd

Use when a feature or substantial change should go from idea to shipped, verified software and an agent may run it for hours on its own — the ASDD (Agent Spec-Driven Development) dispatcher and front door, in any language. A spec that must prove itself, review inside every task scaled by `rsc risk`, a decision queue for what the agent must not decide alone. Routes constitution -> specify -> clarify -> plan -> tasks -> analyze -> implement (verify + review per task) -> closing -> ship. Successor of `sdd`. NOT a single phase (it dispatches), NOT small authorised changes (that is `ftd`), NOT the workspace harness (that is `harness`).

# asdd — Agent Spec-Driven Development

*The front door for letting an agent build for hours without coming back with a Frankenstein: intent in, shipped-and-verified software out, every decision recorded in `02-DOCS/wiki/sdd/`.*

**Why it exists.** Classic SDD reviewed at the end. On paper it checked the spec; in a long autonomous run, the only thing that bit for hours was the test — and tests prove the code works, not that it does what was asked (a real run: 8 hours, 4,500 green tests, and a dropped token plus a QR nobody requested). ASDD keeps the phases and changes two things: **the spec must prove itself**, and **the review moves inside every task**, scaled by risk. The human stops reviewing everything and only takes the decisions the agent must not take alone.

This skill does **not** do a phase. It names the method, reads the register, places the request on the map and hands off. Each phase skill points at the next one.

## The five stages
