cost-reflect skillA

cost-reflect is agent-read markdown (skill) from gtapps/claude-code-hermit: The 'why is my bill high' skill: audits where spend goes across token categories (cache_read, cache_write, output, input) and per-session attribution. Invoke for questions like 'cost breakdown', 'which sessions are expensive', 'what's driving spend', or 'cold start costs'. Not for week-over-week trend lines (use hermit-evolution) or simple total-spend summaries..

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 gtapps/claude-code-hermit/cost-reflect@git:20260905.74ec8ce
Exact content
mdr add gtapps/claude-code-hermit/cost-reflect@sha256:3e37f8007b03d02c

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.
