# herdr-annotate
Annotate inside [Herdr](https://github.com/herdrdev/herdr): comment on any terminal text, review whole Markdown documents and your agent's replies, and send the feedback straight back to the agent. Document review is powered by [plannotator-tui](https://github.com/plannotator/plannotator-tui), which also runs on its own outside Herdr.

## Requirements
- Herdr 0.8.0 or later
- macOS, Linux, or Windows
There is no runtime to install. Both installs download a small prebuilt `herdr-annotate` binary and verify its SHA-256 checksum.
On Linux, install `wl-clipboard`, `xclip`, or `xsel` for clipboard access.
On Windows, native Herdr plugin support is preview/best-effort. Lite installs on Herdr 0.8.0 or later; Full installs through the Windows Full variant below, which needs Herdr 0.9.0 or later. Clipboard access uses PowerShell; no extra clipboard package is required. The install, keybinding, configuration check, reload, and use instructions below also apply on Windows.
## Install
Pick one. Installing another later just swaps it (same plugin id). An install stays on the commit it came from; run the same command again to move to the current release.
<img src="assets/install-full.svg" width="200" align="left" alt="Full">
**Full:** annotate terminal text, review documents and agent replies, send feedback to the agent.
Wraps [Plannotator TUI](https://github.com/plannotator/plannotator-tui) (macOS and Linux; Windows via the windows-full variant below). [Demo](https://x.com/plannotator/status/2093419561077154287)
```sh
herdr plugin install plannotator/herdr-annotate
```
<br clear="all">
<img src="assets/install-lite.svg" width="200" align="left" alt="Lite">
**Lite:** the simple version: select text, `prefix+a`, comment in a popover. [Demo](https://x.com/plannotator/status/2092757422322627008)
```sh
herdr plugin install plannotator/herdr-annotate/lite
```
<br clear="all">
**Windows Full (preview):** the Full install on Windows, opt-in. Requires Herdr 0.9.0 or later on Windows.
```sh
herdr plugin install plannotator/herdr-annotate/windows-full
```
It stages `plannotator-tui` natively, so no launcher sits between Herdr and the TUI. It shares the same native runtime as the Lite and Full installs, so annotations and archives stay in one place.
This is a preview. The pane and path handling were verified on Windows 11 x86_64 ([PR #49](https://github.com/plannotator/herdr-annotate/pull/49), [issue #43](https://github.com/plannotator/herdr-annotate/issues/43)). Native ARM64 is untested. Report results on [issue #43](https://github.com/plannotator/herdr-annotate/issues/43).
> **Required.** Bind the keys in Herdr's config.

## Use
### Annotate terminal text
| Key | Action |
|---|---|
| `Ctrl+B A` | comment on the selected text · `Ctrl+S` saves |
| `Ctrl+B Shift+A` | copy all annotations as Markdown |
| `Ctrl+B Ctrl+A` | copy all annotations as Markdown, then archive them |
| `Ctrl+B Ctrl+V` | paste all annotations into the focused agent's prompt without sending, then archive them |
| `Ctrl+B Ctrl+S` | send all annotations as the focused agent's next message, then archive them |
| `Ctrl+B M` | manage · `e` edit the selected comment · `y` copy one · `c` copy all · `Shift+C` copy and archive · `Tab` archives (`y` copy · `u` restore · `d d` delete) |
In the manager's active view, `e` opens the selected comment in the editor. `Ctrl+S` saves it;
`Esc` cancels. Editing leaves the selected text, capture metadata, and original ordering unchanged.
If another pane saves that comment first, saving your stale draft is rejected and the draft stays
open. To edit the latest version, cancel with `Esc`, then press `r` in the manager to reload.
Annotations are listed and handed off oldest first, in the order you wrote them, so the agent
reads your feedback in the same order you went through the text. The Markdown uses Plannotator's
feedback format: one numbered `## Annotation N` per note, headed with the workspace and tab it came
from, then `Comment on:` with the selected text and your comment as a `>` quote.
Copies made inside the manager pane also emit OSC 52, so on Herdr 0.9.0 they reach the clipboard of
the machine you are viewing from even when the plugin runs on a remote server with no clipboard tool
installed; `Ctrl+B Shift+A` and `Ctrl+B Ctrl+A` do not, because those actions run outside a pane and
have no terminal to write to.
`Ctrl+B Ctrl+V` and `Ctrl+B Ctrl+S` skip the clipboard and put the same Markdown straight into the
prompt of the agent in the focused pane. Both first ask Herdr whether the agent is ready. When
that pane has no running agent Herdr recognises, the agent is still launching, or it is waiting at
an approval or question prompt, they refuse, type nothing, and leave your annotations active.
### Review documents and agent replies
Full install. Works with Claude Code, Codex, pi, Copilot CLI, Droid, Oh My Pi, Hermes CLI and OpenCode (1 and 2).
| Key | Opens |
|---|---|
| `Ctrl+B O` | this folder, with a file tree |
| `Ctrl+B Shift+O` | the agent's recent replies |
| `Ctrl+B Ctrl+O` | the agent's newest reply, with no picker |
| Ctrl-click a `file://…md` link | that file, only with the opt-in Links add-on below |
`annotate.terminal` opens the focused pane's recent terminal output (the last 200 lines) for
review in the same way. It has no default key; to use it, bind one yourself, for example:
```toml
[[keys.command]]
key = "prefix+t"
type = "plugin_action"
command = "annotate.terminal"
description = "review this pane's recent output"
```
#### Ctrl-click Markdown links (opt-in)
Annotate does not capture Ctrl-click on links by default, so `file://…md` links open the way
Herdr normally opens them. To send Ctrl-clicked `file://` Markdown links (`.md`, `.markdown`,
`.mdx`) to Annotate instead, install the Links add-on next to the Full install (on Windows, next
to Windows Full):
```sh
herdr plugin install plannotator/herdr-annotate/links
```
To turn it off again:
```sh
herdr plugin uninstall annotate-links
```
The add-on has no binary of its own; it opens the file with the Full (or Windows Full) plugin's
plannotator-tui. If neither is installed, Ctrl-click shows a notification saying which one to install.
> **Upgrading from 0.8.0 or earlier:** up to plugin 0.8.0, the Full install captured these clicks
> itself. From 0.9.0 it does not
> ([#69](https://github.com/plannotator/herdr-annotate/issues/69)). Install the Links add-on to keep
> the old behavior.
**Send** (or `E`) makes the review the agent's next message. `q` closes. On an agent reply, `S`
sends and closes in one key; `E` and `q` are unchanged.
| Option | Where |
|---|---|
| Agents request reviews themselves | `npx skills add plannotator/herdr-annotate --skill plannotator-tui -g` |
| Open as full tab, split, or popup | `[herdr] placement = "overlay" \| "split" \| "popup"` in `~/.config/plannotator-tui/config.toml` |
| Use without Herdr | [plannotator-tui](https://github.com/plannotator/plannotator-tui) |
### Remote sessions
Over SSH or `herdr --remote`, the plugin runs on the **server**, and two things get in the way:
Herdr's default copy-on-select clears the selection on mouse-up, and the prefix keypress
clears whatever selection remains before a bound action runs
([herdrdev/herdr#3380](https://github.com/herdrdev/herdr/issues/3380)). A headless server also
has no clipboard for the plugin to fall back to.
What works today:
1. On the server, keep the selection after mouse-up:
```toml
# remote server: ~/.config/herdr/config.toml
[ui]
copy_on_select = false # the selection stays; copy explicitly with Ctrl+C
```
2. Trigger the action **without a keypress in Herdr**, while the selection is still
highlighted. From your laptop, bound to any key in your terminal or OS:
```sh
ssh <host> herdr plugin action invoke annotate.capture
# named session on the server: ssh <host> HERDR_SESSION=<name> herdr plugin action invoke annotate.capture
```
The action reads the focused pane's selection through Herdr's API, which never touches the
keyboard path, so the text arrives. Verified: the same selection gives `selected_text` this
way and nothing through `prefix+a`.
3. In Neovim, use the mapping below; it hands the selection over in a file.
Server-side key bindings and `herdr --remote <host> --remote-keybindings server` are still
needed for the manager (`prefix+m`) and other plugin keys; without the flag, `herdr --remote`
uses your local keys and drops plugin bindings. `prefix+a` itself will work once
herdrdev/herdr#3380 is fixed.
## Selection limits
Herdr Annotate reads text that Herdr copies to the system clipboard. The plugin cannot read selection state from Neovim or another terminal application.
## Development
The plugin is a Rust binary in `rust/`.
```sh
cargo test --manifest-path rust/Cargo.toml
cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
bash scripts/stage-local.sh # build and stage bin/herdr-annotate.exe
herdr plugin link "$PWD" # or "$PWD/lite" for the Lite variant
```
`herdr plugin link` does not run manifest build hooks, so stage the binary first. It also replaces
any existing `annotate` link; link the other directory to switch back.
The Links add-on has no build step: `herdr plugin link "$PWD/links"` links it as `annotate-links`.
`bash scripts/lite-regression.sh` checks the runtime against goldens recorded from the retired Bun
runtime. [docs/lite-testing.md](docs/lite-testing.md) covers what it compares and everything else
that guards Lite.
To test a local plannotator-tui build instead of the pinned release, put it in `bin/`
before linking: `PLANNOTATOR_TUI_BIN=/path/to/plannotator-tui bash scripts/fetch-plannotator-tui.sh`.
Before a release, `HERDR_SESSION=<disposable session> bash scripts/smoke.sh` installs fresh, upgrades
from the first shipped commit, installs lite, swaps to full, and opens the manager and review panes,
then restores whatever was installed.
## Neovim integration
Add this visual-mode mapping to `~/.config/nvim/lua/config/keymaps.lua` for LazyVim, or to `init.lua`:
```lua
vim.keymap.set("x", "<leader>a", function()
-- Hand the selection to the plugin through a file: works on headless servers too.
vim.cmd('normal! "zy')
local base = os.getenv("XDG_RUNTIME_DIR")
if not base or base == "" then base = vim.fn.fnamemodify(vim.fn.tempname(), ":h") end
local dir = base .. "/herdr-annotate-" .. vim.loop.getuid()
vim.fn.mkdir(dir, "p", "0700")
vim.fn.writefile(vim.split(vim.fn.getreg("z"), "\n"), dir .. "/selection")
vim.fn.jobstart({ "herdr", "plugin", "action", "invoke", "annotate.capture" })
end, { desc = "Annotate in Herdr" })
```
Select text with the mouse or Visual mode. Then press `<leader>a` to open Herdr Annotate.
The file is read once and removed; a file older than 15 seconds is ignored.
LazyVim uses `Space` as `<leader>` by default. The mapping keeps mouse support and leaves normal Neovim commands unchanged.
