intercom

intercom is a skill for Claude Code, Codex from sanztheo/claude-intercom. It costs 42 tokens per session (639 once invoked), scanned A, original, MIT.

A coordination helper for multiple coding agents working on the same project. It checks messages and announces agent activity through an inter-agent communication system.

In plain words
What is it for?
Use it to discover active agents, share work plans, report completed work or problems, and ask other agents for context.
Why use it?
It reduces duplicated work and helps agents avoid editing the same files or missing important updates.

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

intercom 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 4d 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.

Intercom — Inter-Agent Communication

Purpose

Coordinate with other Claude Code instances working in parallel. Avoid file conflicts, duplicate work, and wasted effort by communicating proactively.

MANDATORY — On Every Task Start

Before doing ANY work, run these two calls:

  1. mcp__intercom__who() → discover who else is active on this project
  2. mcp__intercom__peek() → check if anyone sent you a message

If other agents are active, consider sending a brief message about what you're about to work on.

When to Communicate (Proactively)

Send a message (mcp__intercom__send) when:

Situation Example message
Starting work on a file "Je commence à modifier src/auth/middleware.ts"
About to create a PR or push "Je vais push sur feature/auth, heads up"
About to create a git worktree "Je crée un worktree pour feature/billing"
Finished a task that unblocks others "Auth middleware terminé et mergé, vous pouvez pull"
Found a bug or issue affecting others "Attention: la migration DB 042 est cassée, ne pas merger"
Need information from another agent "Qui gère le rate limiter ? J'ai besoin de contexte"

When to Check Messages

Call mcp__intercom__peek():

  • At task start (mandatory)
  • Before modifying shared files (package.json, schema, configs)
  • Before git operations (push, merge, rebase)
  • Periodically during long tasks (every ~10 tool calls)
  • Before claiming work is done

How to Reply

When you receive a message:

  • If it asks a question → mcp__intercom__reply(message_id, "your answer")
  • If it's informational → mcp__intercom__ack(message_id) after reading
  • If it warns about a conflict → adjust your work accordingly, then reply

Scope

  • who(scope="project") → agents on the same project (default)
  • who(scope="all") → all agents everywhere
  • send(to="all", ...) → broadcasts to same-project agents
  • send(to="x7k2", ...) → direct message to a specific agent (works cross-project)

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.
