Blocks file modifications (edit, write tools) when no automaton task is in implement or doc_review phase. Calls status.py --can-edit --file <path> --json before every edit.

Installation

The framework install/update scripts auto-register this plugin in ~/.config/opencode/opencode.json (or opencode.jsonc):

{
  "plugin": ["~/.automaton/plugins/automaton-guard"]
}

Other Harnesses

Harness	Plugin	Status
OpenCode	`plugins/automaton-guard/plugin.ts`	✅ Active
Pi Dev	`plugins/automaton-guard-pi/guard.ts`	✅ Active
Other	N/A	N/A

To add support for a new harness, create a plugin in plugins/ that calls status.py --can-edit --file <path> before tool execution, matching the contracts/harness-integration.md specification.
