doubt-driven-development skillA

doubt-driven-development is agent-read markdown (skill) from mycelium-hq/ai-brain-starter: Use when correctness matters more than speed: about to commit non-trivial code, make an architectural call under uncertainty, work in unfamiliar code, or assert what the compiler cannot check (''this is safe'', ''thread-safe'', ''this scales'', ''matches the spec''). Strongest on high-stakes surfaces (production deploys, security-sensitive logic, data migrations, irreversible operations) and when the user asks to sanity-check, red-team, double-check, or get a second opinion on a decision..

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 mycelium-hq/ai-brain-starter/doubt-driven-development@git:20260707.f0ac903
Exact content
mdr add mycelium-hq/ai-brain-starter/doubt-driven-development@sha256:16eecbed1ff1ef27

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.
