Hydra Tools
Wire multi-agent pub/sub messaging with TOON-encoded payloads so separate Claude or custom agents can coordinate without ad-hoc file drops.
Overview
hydra-tools is a plugin marketplace for the Build phase that provides hydra-mail multi-agent pub/sub messaging with TOON encoding.
What is this marketplace?
- 1-plugin hydra-tools marketplace shipping hydra-mail v0.1.0
- Multi-agent publish/subscribe messaging designed for AI agent coordination
- TOON encoding called out for compact structured message payloads
- Hydra tools positioning: coordination primitives for agent swarms
- Open-source home at github.com/0xPD33/hydra-tools
- 1 plugin (hydra-mail) in the marketplace
- hydra-mail version 0.1.0
- Metadata describes Hydra tools for AI agent coordination
What problem does it solve?
When you run more than one agent role, ad-hoc message passing becomes brittle and silently drops tasks.
Who is it for?
Builders prototyping multi-agent Claude workflows who need a dedicated mail bus rather than a monolithic single-agent skill.
Skip if: Single-agent coding sessions or teams that already standardize on Slack, queues, or a full orchestration framework.
What do I get? / Deliverables
After install, agents can publish and subscribe through hydra-mail instead of inventing one-off IPC for every project.
- hydra-mail plugin enabled for inter-agent messaging
- Pub/sub channel for coordinated agent handoffs
- Foundation for expanding Hydra coordination tooling

Recommended Marketplaces
Journey fit
Agent coordination infrastructure lands while you are composing multi-agent build and ship workflows, even though messaging also helps grow/operate automations later. hydra-mail is an integration layer for inter-agent mail, not a UI generator or test runner—fits integrations under Build.
How it compares
Agent coordination MCP/plugin, not a memory graph, browser sandbox, or DevOps deploy skill.
Common Questions / FAQ
Who is Hydra Tools for?
It is for developers coordinating multiple AI agents who want pub/sub messaging bundled as a Claude plugin marketplace entry.

How do I add Hydra Tools to my agent?
Register the Hydra Tools marketplace in Claude Code, enable the hydra-mail plugin from ./hydra-mail/.claude-plugin, and configure publishers/subscribers per the GitHub repo docs.
