# Use Plannotator with Copilot CLI

> Install Plannotator's Copilot CLI plugin for plan interception, code review, and document annotation.

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](/open-source/start/installation). Then run these commands in Copilot CLI:

```text theme={null}
/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.

## Manual commands

```text theme={null}
/plannotator-review
/plannotator-review https://github.com/owner/repo/pull/123
/plannotator-annotate path/to/spec.md
/plannotator-last
```

`/plannotator-last` reads Copilot CLI's session event log. That log format is controlled by Copilot CLI and may change between versions.
