8 plugins that make the agent smarter.
Every Hermes Agent install ships with 8 custom plugins built in. They add coding expertise, task boards, multi-agent collaboration, workflow automation, and more — no installation needed. Full docs at /docs/plugins.
> matrix_coder
Turns the agent into a focused coding specialist. Automatically routes your request to the right expert role — planning, building, reviewing, debugging, or testing.
docs → matrix-coder> workflow-engine
Lets you design multi-step processes as visual flowcharts. The agent follows each step, branches on conditions, runs tasks in parallel, and waits for your approval at key points.
docs → workflow-engine> a2a_fleet
Lets multiple agents work together. Deploy specialist agents (Claude Code, OpenCode, Codex) and have them trade tasks back and forth on the same project.
docs → a2a-fleet> mcp_lazy
Saves tokens by only loading tool details when the agent actually needs them. Cuts MCP overhead by ~80% per conversation turn.
docs → mcp-lazy> kanban
Visual task boards the agent can read and update. Drag cards between columns, assign tasks to agents, attach files, and track progress. Powers the Boards and Tasks pages.
docs → kanban> karpathy-self-improve
The agent proposes improvements to itself. You approve, it applies the change, tests it, and keeps or reverts automatically. Powers the Self-Improve page.
docs → karpathy-self-improve> personas
A library of 20 ready-made agent personalities. Pick one during profile setup and the agent adopts that persona's style, tone, and expertise.
docs → personas> hermes-switch-ui
Keeps SwitchUI and the agent in sync. Registers the frontend on startup, sends regular heartbeats, and shares settings so both sides always know what the other is doing.
docs → hermes-switch-uiAlways in sync. Automatically.
The hermes-switch-ui plugin keeps SwitchUI and the agent connected. It registers on startup, sends regular heartbeats, and shares your settings — so both sides always know what the other is doing. You can see the live status in Settings under "Hermes Plugin".
