beeper

An automated message-summary agent that reads incoming messages from the last hour through Beeper Desktop, groups them by sender, and sends a summary to Poke. Beeper Desktop is a messaging app that provides a local API for connected chats.

In plain words
What is it for?
Use it for hourly message checks, sender-based grouping, short recent-message summaries, and delivery of those summaries to a Poke agent.
Why use it?
It reduces the need to check multiple conversations and manually summarize recent incoming messages.

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

beeper 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 yesterday.

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.

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Beeper Agent

The Beeper agent fetches messages from the last hour via Beeper Desktop's local API, groups them by sender, and sends a summary to your Poke agent.

What it does

Every hour:

  1. Calls Beeper's local API at http://localhost:23373
  2. Searches for messages from the last 60 minutes
  3. Filters out messages you sent (only shows incoming)
  4. Groups messages by sender name
  5. Formats a summary with sender name, message count, and last 3 messages
  6. Sends the summary to Poke via sendMessage

Prerequisites

  • Beeper Desktop running on your machine
  • Beeper API token (find it in Beeper Desktop > Settings > API)
  • Signed in to Poke (npx poke login)

Install

npx poke-gate agent get beeper

When prompted, paste your Beeper token:

BEEPER_TOKEN (Find it in Beeper Desktop > Settings > API): <paste>

Test

npx poke-gate run-agent beeper

Expected output:

[agents] Running agent: beeper (beeper.1h.js)
[agents] [beeper] Fetching messages from the last hour...
[agents] [beeper] Found 42 messages
[agents] [beeper] Sending summary to Poke...
[agents] [beeper] Summary sent to Poke.
[agents] [beeper] completed

What Poke receives

Your Poke agent gets a message like:

Messages from the last hour (3 people):

Alice (5 messages):

  • Hey, are you free for lunch?
  • The meeting got moved to 3pm
  • Can you review my PR?

Bob (2 messages):

  • Deployed the fix
  • All tests passing now

Mom (1 messages):

  • Don't forget dinner tonight!

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.
