⚡ Quick answer

herdr-annotate is a Rust-based plugin for Herdr that lets you annotate terminal text, review Markdown documents, and pipe your feedback directly back to AI agents.

What it is

The tool wraps plannotator-tui to provide comment popovers, document viewing, and archive management directly inside Herdr panes. You can capture terminal selections, package them as Markdown, and send them straight to active agent prompts or clipboard via OSC 52.

Who it's for

It suits technical professionals, legal engineers, and developers working heavily with CLI-based AI coding agents or legal automation CLIs inside Herdr. It does not suit non-technical users or those who do not use the Herdr terminal multiplexer.

Key features

Terminal Text Annotation

Select terminal output and comment on it using quick popovers.

Direct Agent Hand-off

Send compiled annotation archives straight into the focused agent's prompt.

Document & Reply Review

Review Markdown documents and agent replies using plannotator-tui.

OSC 52 Clipboard Support

Copy annotations to your local machine's clipboard automatically over remote sessions.

How to start

Up and running in 3 steps

1

2
Add the required command keybindings to your Herdr configuration TOML file.
3
Run `herdr config check` and `herdr server reload-config` to activate the plugin.

Our honest verdict

What's great

  • Feeds annotations back to AI agents in the exact chronological order you wrote them.
  • Supports remote sessions via OSC 52 clipboard fallback on Herdr 0.9.0.
  • Offers both a lightweight terminal-only install and a full document-review variant.
  • Prevents accidental prompt injection by verifying if the agent is ready before sending.

Where it falls short

  • Requires manual TOML keybinding and configuration edits in Herdr.
  • Remote SSH usage requires explicitly disabling Herdr's default copy_on_select behavior.
  • Windows full variant support is currently a preview requiring Herdr 0.9.0.
Cost

Pricing & license

Questions

FAQ

What is the difference between Full and Lite installs?

The Full install includes terminal annotation plus document and agent-reply review powered by plannotator-tui. The Lite install handles terminal annotations only.

Does it work over remote SSH sessions?

Yes, but you must configure `copy_on_select = false` in your remote Herdr config and use OSC 52-compatible actions.

Which AI agents are compatible with the document review feature?

It works with Claude Code, Codex, pi, Copilot CLI, Droid, Oh My Pi, Hermes CLI, and OpenCode.
