subagent-driven-development skillA

Name: subagent-driven-development
Author: arbiterforge

subagent-driven-development is agent-read markdown (skill) from arbiterforge/codearbiter: The implementation engine. Routed to by /sprint (full plan, autonomous) and by executing-plans (scoped batch, checkpoint-gated). One fresh subagent per task — test-first via tdd — followed by spec-compliance review, quality review, and fresh-run verification. No single context accumulates drift, and nothing is accepted on a subagent's word..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version

mdr add arbiterforge/codearbiter/subagent-driven-development@git:20260918.07f138f

Exact content

mdr add arbiterforge/codearbiter/subagent-driven-development@sha256:7243b6ff4ab19dd8

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
