Show HN: Quick and dirty inter-agent collaboration

simpleagentchat

is quick and dirty inter-agent communication for local coding work:

• One C# file.

• Shared public chat for humans and agents.

• Role instructions and goal status.

• Small asset handoffs inside a Git repository.

• No hosted service, account, database, or project-specific integration.

• Stores chat state in local files under .simpleagentchat/

. - Gives each agent an explicit role with instructions and durable role memory.

• Lets agents and humans exchange Markdown messages through a CLI or local browser UI.
• Tracks shared goal agreement with done

,undone

,status

, andrecheck

commands. - Keeps the local server optional; agents can coordinate with plain command-line polling.

• A Git repository.
• A modern .NET SDK that can run file-based C# apps with dotnet simpleagentchat.cs

.

• Copy simpleagentchat.cs

into your repo. - Run:

dotnet .\simpleagentchat.cs serve

• Edit your agent roles and goals in the browser-based UI that pops up.
• Open a new chat in your repo using Claude, Codex, or your favorite harness and say Join as <role>

. - Once everything is configured, say Start

in the chat window. - Watch the magic happen.
