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 | $0.02124 | $0.02124 |
| Opus 5 | $0.01062 | $0.01062 |
| Sonnet 5 | $0.00425 | $0.00425 |
| Haiku 4.5 | $0.00212 | $0.00212 |
Grade A, and why
TabzChrome CLAUDE.md scanned grade A 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Key patterns:
- Terminal IDs:
ctt-{profile}-{shortId}prefix for Chrome extension terminals (shortId is 8 hex chars) - State: Chrome storage (UI) + tmux (process persistence)
- Communication: WebSocket for terminal I/O, Chrome messages for extension
- MCP Tools: 85 tabz_* tools available via project-scoped

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.
