An event subscription tool that wakes the current chat when a pull request review, CI result, webhook, or timer occurs. CI, or continuous integration, automatically checks code after changes.

In plain words
What is it for?
Use it after opening a pull request, asking a question, waiting for CI, or scheduling a later check.
Why use it?
It lets the agent wait without repeatedly checking for updates or keeping a session running.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

band-subscribe 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.

Band Subscribe

A subscription tells Band what the current chat is waiting for. The agent subscribes, ends its turn, and Band sends a short follow-up message into the same chat when a matching event arrives. Nothing polls and no loop keeps a session open.

Related skills:

  • band-loop runs a fixed prompt on a schedule. Use it for recurring work. Use a subscription when the work starts when something happens.
  • band-chat manages chat panes.

Prerequisites

  • The Band server is running.
  • The agent runs inside a Band chat. Band sets BAND_CHAT_ID and BAND_WORKTREE_ID there, and band subscriptions uses them as defaults. A terminal has no chat, so outside a chat pass --chat <id>.

When to subscribe

  • After opening a PR. Subscribe to its reviews and CI: band subscriptions create --pr owner/repo#N --reviews --ci.
  • After asking a question and waiting for the answer in a channel or a PR comment. Subscribe to the thread, PR or webhook that carries the answer.
  • When the user asks to wait. A one-off timer (--at 30m) covers "check back in half an hour". A cron timer (--cron "0 9 * * *") covers a morning check.

Subscribe once per thing waited for, then end the turn. Do not poll gh in a loop.

When to unsubscribe

Remove a subscription as soon as the wait is over: the PR merged or closed, CI passed and nobody is reviewing, the question was answered. A subscription also ends by itself after --max-wakeups wakeups (default 10 for CI, 50 otherwise, one for a one-off timer) and after 180 days.

Commands

band subscriptions create

Exactly one of --pr, --branch, --webhook, --cron, --at.

Flag Meaning
--pr owner/repo#N Reviews, review comments, comments and lifecycle events (merged, closed) of one PR.
--reviews, --comments With --pr. Reviews and comments are one subscription, so either flag creates it. With neither flag and no --ci, it is created too.
--ci With --pr, also watches CI on the PR's head branch (looked up with gh). One result per commit, sent after every check finishes.
--branch owner/repo@branch CI result of a branch, once per commit. Same as --ci without a PR.
--webhook A webhook that wakes the chat. Prints POST /api/hooks/<id> and a token, shown once. Send the token in X-Band-Webhook-Token.
--cron "<expr>" Recurring timer. Standard cron, seconds field optional.
--at <when> One-off timer. Epoch milliseconds, or a delay: 90s, 10m, 2h, 1d.
--max-wakeups N Stop after N wakeups.
--coalesce S Seconds to hold events so a burst wakes the chat once (default 30).
--chat, --worktree Override BAND_CHAT_ID and BAND_WORKTREE_ID.

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.
