Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# The cold-cache guard `hooks/cold_cache.py` stops the first prompt after the session's prompt cache expired and prices the ways on, because that prompt re-caches the whole conversation and nothing else shows the price before it is paid. A blocked prompt makes no API request, so the stop is free. It prices carrying on against a fresh session with `.claude/costs/lib/restart.py`, the context budget hook's model. - **Two sources of "cold".** `SessionStart` on a resume carries `prompt_cache_likely_expired`, `context_tokens` and `estimated_cache_write_usd`; the hook keeps the last two in `tmp/cold-cache/<session_id>.json` until a response lands after them. But the cache also expires while the process lives on and no `SessionStart` fires, so the transcript's last main-chain response time, against the TTL the session's own cache writes used, is the second source rather than a fallback. - **The expiry is partial.** The system prompt and tool prefix every session in the environment shares stays warm, so the first request after a gap reads it from cache. The transcript's first response gives its size (its cache read), …

How to install
mdr add vzakharov/muthur/.claude/cold-cache/CLAUDE.md@sha256:b76983c7e3422141The line at the top of this page pins the label git:20261026.79f8fb3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
