scaffold-cost-check skillA

scaffold-cost-check is agent-read markdown (skill) from haabe/mycelium: Measure Mycelium's own scaffold token cost (CLAUDE.md + engine + harness + canvas + memory) and surface a structured estimate. One-shot audit; pair with /framework-health for trend tracking..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add haabe/mycelium/scaffold-cost-check@git:20260726.151b371
Exact content
mdr add haabe/mycelium/scaffold-cost-check@sha256:0ec09e89607d7e4f

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
