cachewise skillA

cachewise is agent-read markdown (skill) from duthaho/skillhub: Prompt-cache economics forensics — why your Claude Code tokens burn so fast, with the numbers to prove it. Parses local ~/.claude transcripts (0 tokens, a bundled Python script does the counting) and attributes every cache-miss rebuild to a cause — idle gaps past the 5-min TTL, mid-session model/effort switches, prefix churn (MCP tool-lists, edited CLAUDE.md, dynamic content), and cold re-boots of a session you could have resumed — each priced in real USD, then prescribes the fixes ranked by dol.

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 duthaho/skillhub/cachewise@git:20260908.9f72705
Exact content
mdr add duthaho/skillhub/cachewise@sha256:eeb6f0276dbe22ab

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.
