Report card

C overall · 2.10/4

github.com/Jimmy-Holiday/xxyy-trade-skill@HEAD · 2 skills · 394t resident (medium) · 17,705t per activation · 42,082t bundle

Resident footprint

394t 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: 91 comma-separated trigger keywords; 216 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 9,337 words (~17,705t), loaded on every trigger. Corpus median 921, p90 2207.

Progressive disclosure

4 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 (`no`, 2 invocations + 2 shell blocks) — verification and state live in code, not prompt.

C overall (2.10/4). 2 skill(s), 394t resident on every message (medium), 17,705t loaded per activation. Weakest axis: body size (D).
