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 | $0.00023 | $0.00235 |
| Opus 5.5 | $0.00009 | $0.00094 |
| Sonnet 5.5 | $0.00005 | $0.00047 |
| Haiku 4.5 | $0.00002 | $0.00023 |
Grade A, and why
gwt-pty-communication 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 8d 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
gwt PTY Communication
Use gwt terminal commands as the transport for agent-to-agent communication.
Commands
send_keys_to_pane: send text to a specific pane.send_keys_broadcast: send text to all running panes.capture_scrollback_tail: read pane output for status/progress.list_terminals: list active pane ids.close_terminal: stop a pane when escalation is needed.
Notes
- Prefer targeted
send_keys_to_panefor deterministic orchestration. - Use
capture_scrollback_tailbefore sending follow-up instructions.
Environment
GWT_PROJECT_ROOT: absolute path to the project root. PTY commands are scoped to the caller's project; panes belonging to other projects are not visible or accessible.GWT_PANE_ID: pane ID of the current terminal session.GWT_BRANCH: branch name of the current session.GWT_AGENT: agent name of the current session.
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.

gwt-pty-communication is a skill published in the GitHub repository akiojin/llmlb (10 stars, last pushed 3d ago), licensed MIT. It adds 23 tokens to every session and 235 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 2026-10-21.
