Use Plannotator with Copilot CLI

The Copilot CLI plugin intercepts exit_plan_mode and opens the plan in Plannotator before Copilot continues.

Install

Install the plannotator command with the standard installer. Then run these commands in Copilot CLI:

/plugin marketplace add backnotprop/plannotator
/plugin install plannotator-copilot@plannotator

Restart Copilot CLI.

Review a plan

Press Shift+Tab to enter Copilot CLI plan mode. When Copilot writes plan.md and calls exit_plan_mode, the plugin opens Plannotator. Approval lets Copilot continue. Feedback returns your annotations so the plan can be revised.
