permafrost

Freeze Claude Code's prompt prefix so DeepSeek's automatic cache always hits. A passthrough proxy that stabilizes the exact request bytes CC emits — deterministic tool order, canonical JSON, volatile-content relocation — plus the env hardening that stops a custom endpoint from busting the cache.

        freeze the prefix · melt the bill


A Claude Code plugin that keeps DeepSeek's prompt cache hitting when Claude Code would otherwise bust it.

cache-stable passthrough proxy · deterministic tool order · env freeze+delta · cold-anchor coalescing · live hit-rate statusline · zero deps

---

Pointing Claude Code at DeepSeek's Anthropic-compatible endpoint is cheap, and a
**vanilla session already hits DeepSeek's cache ~90% on its own** — CC's system
prompt is shared across users, so it stays warm. The cache breaks when your
**tool list isn't stable**: MCP servers connect and reshuffle it, and because
tools render *first* in the cached prefix, any reorder busts everything from
byte 0. Permafrost sits between CC and DeepSeek and rewrites the cache-relevant
bytes so the `tools + system` anchor stays byte-identical turn after turn — then
streams the reply straight back.
