Control herdr from inside it. Manage workspaces and tabs, split panes, spawn agents, read output, and wait for state changes — all via CLI commands that talk to the running herdr instance over a local unix socket. Use when running inside herdr (HERDRENV=1).
Run the integration test suite through the test-runner subagent, including pane/mux coverage when a supported backend is available. Use when asked to "run integration tests", "run e2e tests", "verify integration", "test before release", or "check everything works".
Bundled plugin for pi-spawned Claude pane subagents — provides the Stop hook for transcript surfacing and the subagentdone MCP tool for explicit completion signaling.
Spec-designer-style agent for end-to-end pane integration. Writes or edits a SPEC document at a caller-specified path and calls subagentdone with a SPECARTIFACT: summary so the parent can route to the artifact.
