nulnul-harness skillA

nulnul-harness is agent-read markdown (skill) from seonaru/nulnul-harness: Turn a project idea or recurring workflow into an outcome-first, project-fit, evidence-driven, waste-aware, personally evolving agent system. Before activating, inspect any user-named local task contract such as TASK.md; do not activate when it already provides explicit local inputs, outputs, constraints, and a runnable completion check. Use for project setup, skill or plugin selection, external-write planning, multi-session checkpointing, or evidence-gated agent evolution, and when implementati.

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 seonaru/nulnul-harness/nulnul-harness@git:20260908.a9fd59e
Exact content

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.
