Operate Hermes on IRC with Channel Discipline

IRC is simple, durable, and often more public than modern team chat. That makes operating discipline especially important. Configure the network, identity, TLS behavior, channels, and sender policy before allowing the agent to respond.

Define the network identity

Choose a recognizable nickname and a network connection that uses TLS when the server supports it. If the network requires NickServ or server authentication, store credentials outside the repository. Limit auto-join to the channels that actually need the bot.

IRC identities are not universally strong. Nicknames can change or be impersonated on networks without account services. Prefer account-based metadata where the adapter and network expose it, keep risky tools behind approvals, and treat public-channel instructions as untrusted input.

Configuration checklist

Identify the IRC network, TLS port, and certificate expectations.
Reserve or register the intended bot nickname if supported.
Store network credentials as secrets.
Configure only the required channels.
Decide whether channel replies require a direct mention.
Set a narrow allowlist for command-capable users.
Run hermes gateway setup and select IRC.
Choose a designated delivery channel for scheduled output.
Keep high-risk toolsets out of public-channel sessions.

Design for IRC constraints

Long reports should be summarized or linked rather than emitted as a flood of lines. Respect network rate limits and avoid formatting that depends on rich cards, buttons, or attachments. Direct messages and channel discussions should map to separate sessions so private context does not bleed into public chat.

Reconnect behavior matters. The bot should rejoin only intended channels, avoid duplicate responses after a network flap, and recover its nickname safely if the preferred identity is temporarily unavailable.

Common pitfalls

Connecting without TLS when the network supports a secure endpoint.
Trusting a nickname as permanent proof of identity.
Joining broad public channels with powerful tools enabled.
Posting multiline reports that trigger flood protection.
Responding to every channel line instead of mentions.
Creating duplicate work after a reconnect or replayed message.

Verification steps

Start the gateway and verify a TLS connection to the intended network.
Confirm the bot joins only configured channels under the expected nickname.
Test mention and non-mention behavior in a channel.
Test a direct message and verify its context stays separate.
Change or spoof a test nickname and confirm authorization does not become weaker than intended.
Interrupt the connection, observe rejoin behavior, and verify no duplicate reply.
Inspect logs for plaintext credentials, reconnect storms, flood warnings, or messages routed to the wrong target.
