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 | $0.00025 | $0.00260 |
| Opus 5.5 | $0.00010 | $0.00104 |
| Sonnet 5.5 | $0.00005 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
similarity scanned grade A with 0 findings 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 26d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Inspect Rust Similarity
Use the requested scope, defaulting to src, and start with the repository's
configured diagnostic settings:
rtk proxy similarity-rs src --skip-test --threshold 0.90 --min-lines 8
Honor explicit analysis options and check similarity-rs --help for other modes.
Use --print when source excerpts help; avoid threshold sweeps without a specific
unresolved question. Exploratory thresholds do not change the release gate.
Inspect candidate functions and callers. Share code when it represents the same policy or control flow with the same owner. Preserve thin compatibility aliases, protocol-specific behavior, and distinct security checks even when syntax looks similar. A high percentage alone does not justify traits, generics, or extraction.
For a structural change, inspect coupling as well and follow refactor. Report locations, the shared responsibility if any, and a recommendation, including intentional duplication. Implement changes only within the requested scope and verify the affected behavior.
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.

similarity is a skill published in the GitHub repository nwiizo/tfmcp (372 stars, last pushed 7d ago), licensed MIT. It adds 25 tokens to every session and 260 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-03.
