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 | $0.00409 | $0.00409 |
| Opus 5.5 | $0.00164 | $0.00164 |
| Sonnet 5.5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
tome CLAUDE.md 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 2mo 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
CLAUDE.md
This repo is the tome plugin + CLI. It's installed as a Claude Code plugin from a local Directory marketplace pointing at this checkout, so "the tool an agent runs" is a version-keyed cache copy, not your working tree.
Releasing a tool change (required — easy to miss)
Plugin updates are version-gated and the cache is keyed by version directory. A code change without a version bump reaches no one: claude plugin update sees the same version, reports "already up to date," and the installed cache keeps running the old code.
So whenever you change the tool itself (the CLI in src/tome_cli/, the skills, or the hooks), finishing the work means:
- Bump
versionin.claude-plugin/plugin.json(e.g.1.2.25→1.2.26). If working from a tracked task, itssemver:patch|minor|majorlabel sizes the bump. No label, or no active task: default topatch, or ask if unsure. - Commit + push to
main. - Install it locally:
claude plugin update tome@tome— this refreshes the version-keyed cache to your new code.
The push alone changes nothing an agent invokes; the bump + local install is what makes the change real. Docs-only edits like this file don't touch plugin runtime, so they need no bump.
Running your in-progress changes
The tome on a session's PATH is the plugin-cache copy pinned at session start — not your working tree — and claude plugin update only takes effect on the next session ("restart to apply"). To exercise uncommitted or just-pushed changes in the current session, run the working tree directly:
PYTHONPATH=src python -m tome_cli.cli <args>
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.
