Resident footprint

138t of description text ride in the system prompt of every message across 2 skills (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 27 comma-separated trigger keywords; 66 words. Padding is individually rational and collectively ruinous — it dilutes every co-installed skill.

Body size

Largest body is 2,316 words (~4,377t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

1 auxiliary .md files ship but the body never points at them — the agent won't find them.

Factoring

Scoped to a coherent procedure set.

CLI leverage

Drives a CLI (`xero`, 19 invocations + 43 shell blocks) — verification and state live in code, not prompt.

B overall (3.10/4). 2 skill(s), 138t resident on every message (light), 4,377t loaded per activation. Weakest axis: body size (C).
