What problem does it solve? Knowledge corpora such as note vaults, agent-instruction files, and documentation trees accumulate internal defects over time: passages that contradict each other, directives too vague to act on, temporary workarounds fossilized into policy, and the same rule restated in several places. This Skill audits a bounded corpus against itself and returns a read-only findings ledger with both sides of every conflict quoted. ## Core Features & Use Cases - Four defect detectors: contradiction, vagueness, bandaid, and redundancy, each with named criteria and near-miss rules that prevent false positives. - Precedence-aware conflict classification: distinguishes true contradictions from conflicts that a declared authority ordering settles or that lack one entirely. - Read-only, sensitivity-controlled reporting: the corpus is never edited, quotes can be redacted or withheld under restricted sensitivity levels, and partial coverage is always disclosed. - Use Case: Point the skill at a docs tree before a major release to find instructions that cannot both be followed, gates with undefined pass conditions, and duplicated rules that have drifted apart. ## Quick Start Run sd-coherence-audit with input=docs/,CONTRIBUTING.md to audit those files for contradictions, vagueness, bandaid guidance, and redundancy and return a findings ledger.
