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 | $0.01899 | $0.01899 |
| Opus 5.5 | $0.00760 | $0.00760 |
| Sonnet 5.5 | $0.00380 | $0.00380 |
| Haiku 4.5 | $0.00190 | $0.00190 |
Grade A, and why
tmux-pane-tree 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 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.

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tmux-sidebar
A tmux plugin that adds an interactive sidebar showing sessions, windows, and panes with agent status badges. Written in bash and python3 (curses UI).

tmux-pane-tree.tmux <- polyglot, no-op under TPM, sources the conf when sourced
tmux-pane-tree.conf <- primary tmux config: hooks, keybindings, startup
sidebar.conf <- legacy config (kept for install-live.sh compatibility)

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.

tmux-pane-tree CLAUDE.md is an instructions file published in the GitHub repository sandudorogan/tmux-pane-tree (65 stars, last pushed 3d ago), licensed MIT. It adds 1,899 tokens to every session, about $0.0076 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
