Hermes Action Bridge Tools (5)
hermes_run
delegate a request to Hermes. Optional overrides: `mode`, `preset`, `contextFiles`, `yolo`, `dryRun`, and — to trade cost for speed on simple tasks — `model`, `provider`, `maxTurns`, `timeoutSeconds`. Any effective `execute` request opens an interactive confirmation form first.
hermes_plan
shortcut for `hermes_run` with `mode=plan`.
hermes_capabilities
report configured presets, skills, toolsets, runtime, and policy without inventing live integrations.
