Panel and keys

Where it sits

<leader>v opens and closes the review; <leader>k cycles where it sits. <leader> is OpenCode’s own prefix, ctrl+x unless you changed it. From the palette it is /changes — /review and /diff belong to OpenCode itself.

Placement	What it is for
Right	A pane down the right of the window, with the conversation still beside it
Full	The whole window, for when you are reading rather than chatting

w switches between them from inside the panel. At half width the file list stays — it narrows rather than disappearing, because a review you cannot change file in is a diff viewer.

Settings

All optional, in the review section of ~/.config/opencode-cockpit/config.json or a project’s .cockpit.json (before 0.9 Review read no file, only its plugin entry):

~/.config/opencode-cockpit/config.json

{ "review": { "variant": "full", "source": "branch" } }

variant	right (default) or full — where it opens
source	worktree (default) or branch — what it opens on
keybinds	overrides for the two global keys, e.g. { "cockpit.review.open": "<leader>z" }
enabled	false switches Review off; so does features.review: false

A value Review does not know ("variant": "left") is the default and a ! row in the pane naming the ones it does. See Configuration.

The keys inside the panel are not configurable. They are a closed set that only exists while the panel is open, and the panel gives them straight back when it closes.

Keys

The panel takes the keyboard while it is open, and gives it straight back when it closes.

Key	Does
<leader>v	Open or close the review
<leader>k	Move it: right pane, full screen
j k ↑ ↓	Move
tab	Switch pane
return l →	Open a file, or fold a folder
h ←	Back to the file list
d u pgdn pgup	Scroll the diff
shift+→ shift+← · L H	Scroll the code sideways, to read a long line to its end — or swipe sideways, or shift+wheel
v	Start a selection, or cancel it
c n	Comment here, or reply to the thread here
f	Comment on the whole file
x	Remove the thread you are on
space m	Mark read, and go to the next unread
z	Fold
s	Submit the review
b	Next source: uncommitted, or what this branch changes
B	Pick the base the branch is compared with, remembered per branch
o	On a changed image: open both versions in your system viewer
g	Reload the diff
w	Right pane or full screen
p	Show what the panel is costing
?	Every key the panel takes; esc back
q esc	Close

ctrl+p works while the review is open: it steps aside for OpenCode’s palette.

Submit is s and source is b, which looks arbitrary until you try it the other way: they were s and S for an afternoon, two meanings on one letter separated only by a shift, and one of them sends your review to the agent.

The footer

Two rows, always, because the body’s height is measured from them — a footer that grew would shove the diff about every time something happened. So anything it has to say replaces the keys rather than being added to them, in this order:

1. Trouble. Something threw. It is also written to trouble.log beside the review’s threads, with the stack and what was on screen at the time.
2. The numbers, if you pressed p — how long a frame costs, how many were dropped, how often the row cache hit.
3. The keys, which is what you see the rest of the time.

The numbers are always being kept, whether or not you are looking at them. A debug mode you have to remember to switch on is off during every problem worth seeing.

A thread on screen

A comment is a band across the diff rather than a box: a tinted row spanning the full width is the boundary, so it needs no characters to draw one. Inside it, a dim line says where the thread is and how it stands, and an inverted badge says who is speaking — YOU or AGENT. The thread your cursor is on gets one coloured column in its margin and shows what you can do to it.
