Resident footprint

2,261t of description text ride in the system prompt of every message across 40 skills (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 223 comma-separated trigger keywords; 1160 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 6,082 words (~10,515t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

Body routes to 55 reference file(s); 79 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 (`screen`, 48 invocations + 110 shell blocks) — verification and state live in code, not prompt.

C overall (1.80/4). 40 skill(s), 2,261t resident on every message (heavy), 10,515t loaded per activation. Weakest axis: resident footprint (F).
