necessity-audit skillA

necessity-audit is agent-read markdown (skill) from sd0xdev/sd0x-harness: Necessity audit for over-designed spec elements. Use when: auditing lifecycle spec (1-requirements / 2-tech-spec / 3-architecture) for YAGNI/KISS violations, challenging necessity of FRs/NFRs/abstractions/configs via Codex adversarial debate. Not for: FP reasoning validity (use /codex-review-spec), completeness check (use /feature-completeness), detail review (use /codex-review-doc), or code-level simplification (use /simplify)..

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 sd0xdev/sd0x-harness/necessity-audit@git:20260905.7f65168
Exact content
mdr add sd0xdev/sd0x-harness/necessity-audit@sha256:57ad45a82f36fe34

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.
