Resident footprint

202t of description text ride in the system prompt of every message across 7 skills (paper's observed per-skill range: 50–280t).

Description honesty

Defensive padding detected: 17 comma-separated trigger keywords; 144 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 3,271 words (~5,662t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

14 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

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

B overall (2.50/4). 7 skill(s), 202t resident on every message (light), 5,662t loaded per activation. Weakest axis: description honesty (C).

Six deterministic axes, no LLM, same result every run. Tokens are approximated as chars/4. Read the methodology, or see how SEO skills score on task outcomes in the open SEO skill benchmark.
