  • Code Review(Jan 2026) — Run /plannotator-review to review git diffs with inline annotations (select line numbers to annotate), switch between diff views, and send feedback to your agent
  • Attach and annotate images with your feedback (pen, arrow, circle tools)
  • Auto-save approved plans to Obsidian and Bear Notes

Install for Claude Code

Install the plannotator command:

macOS / Linux / WSL:

curl -fsSL https://plannotator.ai/install.sh | bash

Windows PowerShell:

irm https://plannotator.ai/install.ps1 | iex

Then in Claude Code:

/plugin marketplace add backnotprop/plannotator
/plugin install plannotator@plannotator
# IMPORTANT: Restart Claude Code after plugin install

See apps/hook/README.md for detailed installation instructions including a manual hook approach.

Install for OpenCode

Add to your opencode.json:

{
"plugin": ["@plannotator/opencode@latest"]
}

Run the install script to get /plannotator-review:

curl -fsSL https://plannotator.ai/install.sh | bash

Windows:

irm https://plannotator.ai/install.ps1 | iex

This also clears any cached plugin versions. Then restart OpenCode.

How It Works

When your AI agent finishes planning, Plannotator:

  1. Opens the Plannotator UI in your browser
  2. Lets you annotate the plan visually (delete, insert, replace, comment)
  3. Approve → Agent proceeds with implementation
  4. Request changes → Your annotations are sent back as structured feedback

/plugin install plannotator@plannotator
# IMPORTANT: Restart Claude Code after plugin install

See apps/hook/README.md for detailed installation instructions including a manual hook approach.
Install for OpenCode
Add to your opencode.json:
{
"plugin": ["@plannotator/opencode@latest"]
}
Run the install script to get /plannotator-review:
curl -fsSL https://plannotator.ai/install.sh | bash
Windows:
irm https://plannotator.ai/install.ps1 | iex
This also clears any cached plugin versions. Then restart OpenCode.
How It Works
When your AI agent finishes planning, Plannotator:
  1. Opens the Plannotator UI in your browser
  2. Lets you annotate the plan visually (delete, insert, replace, comment)
  3. Approve → Agent proceeds with implementation
  4. Request changes → Your annotations are sent back as structured feedback
