C overall · 2.45/4
github.com/cas-bigdatalab/piflow@HEAD · 40 skills · 1,587t resident (heavy) · 796t per activation · 16,781t bundle
F
Resident footprint
1,587t of description text ride in the system prompt of every message across 40 skills (paper's observed per-skill range: 50–280t).
B
Description honesty
Defensive padding detected: 137 words (a quiet description is ~15–40). Padding is individually rational and collectively ruinous — it dilutes every co-installed skill.
A
Body size
Largest body is 380 words (~796t), loaded on every trigger. Corpus median 921, p90 2207.
B
Progressive disclosure
Single-file skill small enough to need no reference layer.
A
Factoring
Scoped to a coherent procedure set.
A
CLI leverage
Drives a CLI (`artificial`, 1 invocations + 64 shell blocks) — verification and state live in code, not prompt.
C overall (2.45/4). 40 skill(s), 1,587t resident on every message (heavy), 796t loaded per activation. Weakest axis: resident footprint (F).
