Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00088 | $0.01298 |
| Opus 5.5 | $0.00035 | $0.00519 |
| Sonnet 5.5 | $0.00018 | $0.00260 |
| Haiku 4.5 | $0.00009 | $0.00130 |
Grade A, and why
band-terminal 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 25d 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Band Terminal Sessions
Terminal sessions are PTY processes attached to a Band worktree. Each terminal has its own scrollback buffer and shell process.
This skill is focused on terminal management only. For broader operations see the sibling skills:
band— worktrees, repos, cronjobs, tunnel, settings.band-chat— agent chat panes inside a worktree.band-browser— browser tabs inside a worktree.
Prerequisites
The Band server must be running (started by the Band dashboard app). Connects to http://localhost:3456 by default. See the band skill for general setup and the worktree lifecycle.
JSON Output
All commands support --output json (or BAND_OUTPUT=json env var) for structured output.
- Success: JSON object to stdout, exit code 0
- Error:
{"error": "message"}to stderr, exit code 1
Commands
List terminal sessions for a worktree
band terminals list [worktree_id]
Text output: TERMINAL ID\tTITLE\tPID\tSCROLLBACK (tab-separated table).
JSON output: {"terminals": [{"terminalId": "...", "worktreeId": "...", "pid": N, "scrollbackLength": N, "title": "..."}]}
Create a new terminal session in a worktree
band terminals create [worktree_id] [--command <string>] [--cwd <string>]
Creates a new terminal session with its own PTY process. Returns the terminal ID.
JSON output: {"terminalId": "...", "worktreeId": "...", "pid": N}
Send input to a terminal session
band terminals send [terminal_id] --data <string>
Writes text to the terminal's PTY stdin. Use \n to send a newline (execute command). Example: band terminals send --data "ls -la\n"
Get terminal output (scrollback buffer)
band terminals output [terminal_id] [--lines <integer>] [--follow]
Without --follow: fetches the current scrollback buffer (up to 100KB). With --follow: streams live terminal output via SSE. Press Ctrl+C to stop.
Kill a terminal session
band terminals kill [terminal_id]
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.

band-terminal is a skill published in the GitHub repository band-app/band (5 stars, last pushed today), licensed MIT. It adds 88 tokens to every session and 1,298 once invoked, about $0.0004 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 2026-08-31.
