Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00145 | $0.00145 |
| Opus 5.5 | $0.00058 | $0.00058 |
| Sonnet 5.5 | $0.00029 | $0.00029 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade B, and why
token-saver CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Never wrap sudo commands What it actually says
Token-Saver Plugin
Token-saver automatically compresses verbose CLI output to save tokens.
How it works
- A PreToolUse hook intercepts Bash commands matching known patterns (git, docker, npm, terraform, kubectl, etc.)
- The command output is piped through specialized compression processors
- Compressed output is returned to Claude, saving tokens while preserving critical information
Important rules
- Never wrap
token-saverCLI commands themselves (avoid infinite loops) - Never wrap interactive commands (vim, nano, ssh, etc.)
- Never wrap commands with redirections (>) or complex pipes
- Never wrap sudo commands
- Debug mode: set TOKEN_SAVER_DEBUG=true environment variable
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

token-saver CLAUDE.md is an instructions file published in the GitHub repository ppgranger/token-saver (161 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 145 tokens to every session, about $0.0006 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root).
