broadcast

broadcast is a command for Claude Code from garniergeorges/claude-presence. It costs 22 tokens per session (372 once invoked), scanned A, original, MIT.

A project messaging command for posting a message that other coding sessions can see. Messages can be sent to everyone or to one session, with an information, warning, or urgent priority.

In plain words
What is it for?
Use it to announce progress, report problems, or pass instructions between sessions working on the same project.
Why use it?
It keeps separate work sessions informed without manually sharing updates elsewhere. It also makes important messages easier to notice.

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

broadcast 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 6d 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

Call the claude-presence MCP broadcast tool.

Parse $ARGUMENTS:

  • If it begins with --to <session-id>, capture to_session and remove that prefix from the message.
  • If it begins with --priority <info|warning|urgent>, capture priority and remove that prefix.
  • Both flags may appear in any order; the rest is the message. If message is empty after parsing, ask the user what to post.

Required args for the tool:

  • session_id: this session's id (from session_register). If unknown, ask the user to /register first, then retry.
  • project: the project's absolute path.
  • from_branch: the current git branch if available (git rev-parse --abbrev-ref HEAD); omit if not a git repo.
  • message: the parsed message string.
  • to_session: only set if --to was passed.
  • priority: only set if --priority was passed (default info server-side).
  • tags: optional, only set if the message clearly starts with a category prefix like ci:, refactor:, etc.

After posting, confirm in one line: the message id, target (→ <session> or → all), and priority. Remind the user that warning and urgent messages will appear automatically on the recipient's next prompt; info requires /inbox.

Keep messages short. This is a bulletin board, not chat.

Changes

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.
