SavingPrivateToken
Keep Claude Code's prompt cache warm while you think.
Anthropic's prompt cache has a 5-minute TTL. If you step away from an interactive Claude Code session for more than 5 minutes — to grab coffee, read a spec, or just think — the cache expires and the next turn re-processes the entire prefix. `SavingPrivateToken` (`spt`) injects a tiny keepalive ping every 4:50 of idle via `tmux send-keys`, refreshing the TTL with a 1-token `pong` round-trip.
Prerequisites
**All of these must be installed and on `PATH` _before_ you run the `spt` installer.** The installer shells out to `claude` to register its plugin and to `tmux` at runtime to inject pings — neither is optional.
| Requirement | Why | Install |
|---|---|---|
Claude Code (claude on PATH) |
spt registers a plugin via claude plugin marketplace add + claude plugin install. Without claude at install time, hooks never fire. |
docs.claude.com/en/docs/claude-code |
| tmux ≥ 3.0 | The ping is injected via tmux send-keys into the claude pane. |
brew install tmux (macOS) · apt install tmux (Debian/Ubuntu) |
| Node.js ≥ 18 | spt and its install script are Node ESM. |
nodejs.org or brew install node |
| Bash (POSIX shell) | Plugin hooks are bash scripts. macOS and Linux are supported. Windows/PowerShell is not. WSL works. |
system default |
If `claude` or `tmux` is missing when you install, `spt` will warn and continue — but the keepalive won't work until both are present. You can re-register anytime with `spt install-plugin`.
