Resident footprint

456t of description text ride in the system prompt of every message across 8 skills (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 27 comma-separated trigger keywords; 243 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 1,825 words (~3,319t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

Body routes to 2 reference file(s); 2 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 (`git`, 3 invocations + 41 shell blocks) — verification and state live in code, not prompt.

B overall (2.80/4). 8 skill(s), 456t resident on every message (medium), 3,319t loaded per activation. Weakest axis: resident footprint (C).
