Resident footprint

499t of description text ride in the system prompt of every message (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 32 comma-separated trigger keywords; 172 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 786 words (~5,064t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

Single-file skill small enough to need no reference layer.

Factoring

Scoped to a coherent procedure set.

CLI leverage

Prompt-only. Every rule stated in prose pays attention rent; consider a companion CLI for deterministic steps.

B overall (2.75/4). 1 skill(s), 499t resident on every message (medium), 5,064t loaded per activation. Weakest axis: resident footprint (C).
