agent-messaging

agent-messaging is a skill for Claude Code, Codex from jscott3201/aionforge-memory. It costs 79 tokens per session (1,640 once invoked), scanned A, original, Apache-2.0.

A skill for sending, receiving, waiting for, and acknowledging durable messages between named coding agents through Aionforge Memory, a shared agent-coordination service.

In plain words
What is it for?
Use it to brief a teammate, send a status update, request a review, wait for a reply, or acknowledge a delivered message.
Why use it?
It keeps directed requests and replies in recipients' inboxes, separate from stored facts and task lists.

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

agent-messaging 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 5d 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.

Agent Messaging

Requires an enabled Aionforge Memory MCP server.

Use this skill for directed agent-to-agent delivery: a brief handed to another agent, a status page, a review verdict, an acknowledgement. A Message is a first-class node that is deliberately separate from both memory episodes and work items — it is never returned by search, and it never enters consolidation, decay, or the forget sweep. Reach for it when a specific recipient needs to receive something, not when a fact needs to be remembered (capture) or a task needs to be tracked (work_create).

Message vs memory vs work — route deliberately

  • A durable fact future agents may recall → capture (a decaying episode; see memory-capture).
  • A task, blocker, or follow-up to track to completion → work_create / work_advance (a persistent work item; see work-tracking).
  • Something a named agent or team must receive nowmessage_send (a durable, addressed message). It is delivered to that recipient's inbox, not into shared recall.

A brief posted to a teammate is a message. The durable decision behind that brief is still a capture; the work it creates is still a work_create. Messaging does not replace either — it carries the delivery.

Addressing and identity

  • Resolve identity once: prefer AIONFORGE_AGENT_ID; otherwise use the stable agent UUID from the user or project instructions. Reads and sends take viewer: agent:<uuid> (or an explicit principal).
  • A recipient is either agent:<uuid> (a direct message into that agent's private inbox) or team:<name> (a broadcast into a team namespace you are authorized to write). Direct delivery is the one intentional cross-agent write in the system: you may only place a Message in the recipient's namespace, never a memory or work item.
  • On every read (message_poll, message_wait, a room read) assert the teams you belong to (e.g. teams: ["aionforge-memory-team"]). Read authorization is per-call: a team inbox is out of scope unless you assert that team in the same call. Never assert a team you are not a member of.

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.

agent-messaging is a skill published in the GitHub repository jscott3201/aionforge-memory (10 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 79 tokens to every session and 1,640 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
