brew trust plannotator/tap && brew install plannotator/tap/plannotator-tui # macOS, Linux
cargo install plannotator-tui # anywhere with RustHomebrew 6 asks you to trust a third-party tap once before installing from it.
Prebuilt binaries for macOS, Linux and Windows are on the releases page.
On x86_64 Linux, choose plannotator-tui-x86_64-unknown-linux-musl if the GNU
binary reports a missing GLIBC_* version, or if you use Alpine. This static
musl build does not require system glibc or a local Rust toolchain. Existing
GNU/Linux binaries remain available. Verify your download against SHA256SUMS
from the same release, make it executable, and put it on your PATH as
plannotator-tui.

plannotator-tui last # your coding agent's recent replies, pick one, annotate itDrag with the mouse (or v, move, then Enter) to select, then a 👍 · c 💬 · d ✗. E
copies the feedback to the clipboard as numbered annotations (# Annotations on plan.md,
## Annotation 1 (line 12), …). Every annotation is saved as JSON the moment you make it; q
closes.
Copies go to the clipboard as OSC 52, which is the terminal you are looking at, so on Herdr 0.9.0
they reach your own machine even when the app runs on a remote server; Herdr Annotate's global
copy-context and copy-archive actions do not, because they run outside a pane.
On an agent's reply, S sends the feedback and closes the window in one key, the same as
q then y. E still sends and leaves the window open. When the agent is at a dialog the
window stays open and the footer says why; press S again to retry. With nothing to send,
or with a review the agent already has, S closes like q. File and folder reviews have
no S; they finish with F.
For file and folder reviews, E sends only new or edited annotations. Send A and B, then
add C: the next send includes just C. Sent notes stay visible with a marker; editing one
makes it pending again, including after a restart. R Resend all includes every active
note. With nothing pending, E reports “nothing new to send”. A failed send keeps the notes
pending for retry.
F Finish review archives sent, unchanged notes and leaves pending ones in place.
U undoes the last finish during this session. H opens the archive, where Enter or a
click restores a note even after reopening the app. Restoring keeps its original id and
sent status. The archive is stored with the annotations and works even when feedback
history is turned off. The header holds the send button and a Review ▾ (m) button whose
menu lists these four actions with live counts (R resend all · 3 sent, F finish review
· archive 3 sent, U undo finish, H archive · 2 notes); rows with nothing to act on are
dimmed. The keys also work without opening the menu.

These are the defaults; every key can be rebound under [keys] (see Keys).
Hidden folders are out of the tree until . asks for them, and .git, .hg, .svn,
.jj, .cache, .direnv, .venv, venv, __pycache__, node_modules, vendor,
target, build, dist and out stay out either way — none of them is read at all.
Showing or hiding is a view choice: notes recorded for a file inside a hidden folder are
part of the review and are sent whether or not its folder is listed.
Ctrl+P matches file names, not contents, ignoring case and allowing gaps (prd finds
product-requirements.md). Results show the path within the folder, so files with the same
name are told apart, and opening one expands the tree down to it. It follows the tree's
hidden-entries setting and skips the same folders the tree does.
Install Herdr Annotate; it bundles this binary,
opens it in a pane with prefix+o (folder) or prefix+shift+o (agent's last reply), and the
header button sends the review straight back to the agent as its next message:
Send 3 new ▸ claude in w1:p2 (E). Ctrl-clicking a file://…md link opens it in Annotate only
if you install the add-on: herdr plugin install plannotator/herdr-annotate/links. Folder reviews show
Send 3 new across 2 files and send one combined feedback message.
# ~/.config/plannotator-tui/config.toml
[herdr]
placement = "overlay" # overlay (full tab, default) | split | popupplannotator-tui herdr last --newest opens the agent's newest reply without asking which
one; without the flag the picker comes first, as it always has.
plannotator-tui herdr terminal [--lines N] opens the focused pane's recent output (the last
200 lines by default; Herdr caps a read at 1000) as a transient review, shown verbatim in one
code block. Send goes to the agent in that pane, as it does for a reply; a pane with no agent
copies instead. --print writes the document to stdout instead of opening a pane. Herdr
Annotate ships it as the annotate.terminal action with no default key.
plannotator-tui config prints the file's path and the values in effect. The herdr/
directory in this repo is the development manifest; users should install Herdr Annotate.
The same file chooses the theme:
[ui]
theme = "auto" # auto (ask the terminal, default) | light | darkOn auto the viewer asks the terminal for its background colour once at startup and uses a
light palette when it finds one; a terminal that does not answer keeps the dark palette it
has always used. The question costs one round trip before the screen is drawn, and a key
pressed into that window is read along with the reply and lost, so set the theme outright if
you habitually type ahead. light and dark skip the
question, and PLANNOTATOR_TUI_THEME=light|dark does the same for one run — the variable
wins over the file, and plannotator-tui config prints whichever is in effect. Only the
backgrounds plannotator-tui paints itself change; the document keeps your terminal's own
colours either way.
[colors] replaces individual roles of whichever palette is in force; a role left out keeps
its light or dark value. A colour is a name (yellow, light-cyan), a 256-colour index
(238, quoted or not) or #rrggbb. An unknown role or colour is an error that names it, and
plannotator-tui config prints the roles you set. Every role, with the dark palette's values
(apart from selection, which is reverse video by default):
[colors]
accent = "cyan" # focused borders and gutter, the open file, menu and picker frames
heading = "cyan" # every heading level
comment = "yellow" # comment titles, the compose box, annotated rows in the gutter
looks-good = "green"
delete = "red" # also the struck-through text
comment-bg = "58" # the tint under commented text
looks-good-bg = "22" # the tint under looks-good text
block = "236" # the focused block and the focused tree row
toolbar = "238" # the floating toolbar and the idle header buttons
cursor = "240" # the keyboard cursor cell
selection = "#45475a" # a character selection, a picker row, a menu rowcursor and selection become plain backgrounds when set: the text on them keeps the
terminal's colour.
Every key is rebindable under [keys]: an action, and the keys that run it.
[keys]
left = ["j", "Left"] # jkl; instead of hjkl
down = ["k", "Down"]
up = ["l", "Up"]
right = [";", "Right"]
line-start = ["^", "Home"]An entry replaces that action's keys and leaves every other action at its default; []
unbinds it. A key is one character (G is Shift+g), ctrl+<character>, or one of Up,
Down, Left, Right, Home, End, PageUp, PageDown, Enter, Esc, Tab,
Delete, Backspace. An action keeps its meaning everywhere it applies, so down moves
down in the document, the tree, the notes and every picker. A key bound to two actions that
are live at the same time is an error that names both, and the hints at the bottom of the
screen show your keys. plannotator-tui config prints every action with its keys.

Actions forwarded by Herdr Mirror default to a split beside the invoking remote
pane. Mirror does not preserve overlay presentation, and Herdr 0.8.2 opens an
overlay in its server's active tab, which can differ from the tab you are viewing.
An explicit --placement or PLANNOTATOR_TUI_PLACEMENT still takes precedence.
plannotator-tui last finds the transcript of the agent that launched your shell and shows a
picker of its recent replies. Hosts: Claude Code, Codex, pi, Oh My Pi, GitHub Copilot CLI,
Droid, Hermes CLI, OpenCode (1 and 2). --host, --pid, --session <transcript> (format sniffed when
no host is named) and --session-id <id> (Hermes, OpenCode) override detection; --stdin
reads a document; --newest skips the picker and opens the newest reply straight away, with
p still opening the picker on the rest;
--print writes the newest reply to stdout and always exits 0 (for hooks and scripts).
A reply review keeps its annotations in memory only; nothing about it survives the run, but
the feedback you send or copy is archived like any other (see Feedback archive below).
On Linux, an explicit Codex --pid selects the rollout opened by that process. If it
cannot be identified uniquely, last reports the failure instead of choosing an unrelated
session. --session and --session-id keep precedence over PID discovery.
Inside Herdr, the exact-session path needs the session id Herdr reports for the pane. Herdr's
Claude Code integration registers on SessionStart, so a session reports its id only when it
started after herdr integration install claude; a session that was already running when the
integration was installed reports none. Without an id, last shows the newest transcript for
the folder, which is a guess when several sessions share one directory, and says so in the
status line.
~/.plannotator/clients/plannotator-tui/annotations/<project>/<slug>/annotations.json
<project> is the git repo name, <slug> the file's basename plus 8 hex of the sha256 of
its path: Plannotator's own layout, so both tools see one record per file. The JSON is the
Plannotator Workspaces wire shape; any agent can read it. Nothing is written next to your
files. PLANNOTATOR_DATA_DIR relocates the directory.
A successful Send or Copy also appends what was submitted (the feedback text, the quoted
selections and their annotations, and the file, folder or agent session it was about) to
{data_dir}/feedback/<project>/index.jsonl, with a Markdown copy under records/. The data
dir is PLANNOTATOR_DATA_DIR, else an existing ~/.plannotator, else
$XDG_DATA_HOME/plannotator, else ~/.plannotator. File, folder and reply reviews are all
archived; a send that fails or is refused is not. The format is the one the Plannotator
browser app writes, so both tools share one history. To turn it off, set
PLANNOTATOR_FEEDBACK_HISTORY=0 (once the variable is set, only 1 or true enable) or put
"feedbackHistory": false in {data_dir}/config.json; the variable wins over the file.
