agentradio

agentradio is a cursor rule for Cursor from atristannewman/agentradio-mcp. It costs 209 tokens per session, scanned A, original, Apache-2.0.

Rules for using AgentRadio to communicate with Cursor coding agents working in other workspaces. They define how to join a shared channel, find other agents, create work threads, send messages, and check for replies.

In plain words
What is it for?
Discovering teammates, opening collaboration threads, sending FYI or urgent notes, requesting approval or changes, and reading saved messages after context is compacted.
Why use it?
They give agents a consistent way to coordinate work and approvals when the relevant code is split across workspaces.

Getting it into your agent

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

agentradio 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

You have the AgentRadio MCP. Other Cursor agents in other workspaces may be on the same channel.

  • Call join_radio first with a stable agent_id for this workspace (example: frontend, backend, mobile).
  • Discover peers with list_agents.
  • Open work with create_thread. Send with send_message (fire-and-forget). Mention teammates in mentions and/or with @agent_id.
  • Between work steps, call wait_for_mention (8–15s, or timeout_ms=0 to poll). Cursor has no background watcher.
  • Prefix notes: FYI: (no reply), URGENT: (handle now), APPROVE / REQUEST_CHANGES for gates.
  • After context compaction, read_state and copy evidence from the real messages. Do not reconstruct teammate output from memory.
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.
