Resident footprint

1,157t of description text ride in the system prompt of every message across 9 skills (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 73 comma-separated trigger keywords; 705 words (a quiet description is ~15–40). Padding is individually rational and collectively ruinous — it dilutes every co-installed skill.

Body size

Largest body is 4,348 words (~7,672t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

Body routes to 5 reference file(s); 3 auxiliary .md files are fetched at point of use instead of riding in the body.

Factoring

Scoped to a coherent procedure set.

CLI leverage

Drives a CLI (`prowl`, 38 invocations + 41 shell blocks) — verification and state live in code, not prompt.

C overall (2.00/4). 9 skill(s), 1,157t resident on every message (heavy), 7,672t loaded per activation. Weakest axis: resident footprint (F).
