The description uses abstract, jargon-heavy language like 'HE cognition artifacts' and 'evidence-backed strategy' without listing concrete actions. 'Compress' is vague and no specific outputs or operations are described.

It attempts to answer both 'what' (compress cognition artifacts into strategy) and 'when' (when evidence needs durable direction), but both are expressed in opaque domain jargon that makes the triggers effectively unclear. The 'Use when' clause exists but is not actionable.

The terms used ('HE cognition artifacts', 'durable direction', 'source-prompt comparison evidence') are highly specialized jargon that users would not naturally say. While 'intent', 'review', 'triage', and 'ADR' are somewhat recognizable, they are too generic and context-dependent to serve as effective trigger terms.

The highly specialized jargon makes it unlikely to conflict with common skills, but terms like 'intent', 'review', 'triage', and 'ADR' are generic enough to potentially overlap with other skills. The niche is unclear rather than clearly defined.

The skill is moderately efficient but includes several sections that feel verbose or redundant for Claude (e.g., the Philosophy section restates what the skill already implies, and some constraints/boundaries overlap). Phrases like 'cognition compression, not ceremony' are stylistic but don't add actionable value. However, it avoids explaining basic concepts and most sections carry meaningful content.

The skill is almost entirely abstract and procedural in tone with no concrete code, commands, file templates, or copy-paste-ready examples. Steps like 'Resolve he-strategy in routing-map.json' and 'Apply source-prompt, first-principles contract' give no executable detail. The Examples section lists user prompts but provides no corresponding output examples or artifact templates.

The 10-step Procedure provides a numbered sequence, and there is a Validation section with named gates. However, validation checkpoints are vague ('validate the artifact against the selected mode contract'), there are no concrete feedback loops showing what to do when a gate fails beyond 'rerun failed gates', and the relationship between steps is implicit rather than explicit. The 'Do Not Create' escape hatch is a good pattern but lacks clear trigger criteria.

The References section is well-structured with clear conditional triggers ('Read when selecting mode output', 'Read when architecture lenses apply') pointing to one-level-deep reference files. The skill body stays at overview level and routes detailed contracts, lenses, and pipelines to external files with descriptive paths. Navigation is clear and well-signaled.
