Gateway Sessions Across Discord, Slack, and CLI

Design session keys so one agent can talk through many surfaces without mixing users or channels.

What the local Hermes build teaches

This build lab focuses on the session model that lets messaging gateways feel continuous without leaking context. The goal is not to copy a private machine setup. The goal is to learn the architecture pattern well enough to build a small, classroom-safe version.

Every incoming message should be normalized into a session source: platform, workspace, channel, thread, user, and persona.

Hermes pattern	Student build	Risk to handle
Name the boundary	a session-key design for CLI, Discord, Slack, and a classroom web chat	using only a username as identity and accidentally merging two different people, classes, or channels
Keep the interface small	Start with one happy path and one failure path	Avoid a demo that only works when everything is perfect
Make the system observable	Log decisions, status, and errors in plain language	Do not log private data or secrets

Build the small version

Draw or write a session-key design for CLI, Discord, Slack, and a classroom web chat.
Mark which parts are user-facing, which parts are internal, and which parts require approval.
Choose one low-risk workflow and implement only that workflow first.
Add one failure case before adding a second feature.
Write a short operator note: what the agent may do, what it must ask about, and what it must never do.

session_key = join(
  platform,      # cli, discord, slack, web
  workspace_id,  # server, team, class, or local profile
  channel_id,
  thread_id,
  user_id,
  persona_id
)A classroom-safe skeleton inspired by the local Hermes architecture scan.

The big idea: session key is not decoration. It is part of the product architecture students need before an agent becomes safe enough to use with real people.
