I'm proud to present OhMyStash! OMS stores unfinished OhMyPi prompts without submitting them. It preserves normal and /queue drafts, images, collapsed large pastes, timestamps, source-chat metadata, locks, and a whole lot more!
I had a ton of fun making this, and I hope you find it just as useful as I do!
OMP's plugin manager uses Bun for package installation:
brew install bunInstall OhMyStash directly from GitHub:
omp plugin install github:hkay-dev/OhMyStashRestart OMP, then open the browser with Alt+Shift+S or /stash.
Version 1.8.4 has been checked against OMP 18.1.11.
To update OhMyStash after a new release:
omp plugin install --force github:hkay-dev/OhMyStashCheck the installed package and extension manifest with:
omp plugin doctor @hkay-dev/ohmystashOMP uses the package ID @hkay-dev/ohmystash for plugin settings and diagnostics. Existing stash storage paths do not change.
Press Alt+S while the composer contains a prompt to stash it immediately. The composer clears so you can move to something else.
Press Alt+S on an empty composer to restore the newest stash from the current chat. The stash remains saved after restoration.
Press Alt+Shift+S to open the full stash browser. The browser supports preview, search, chat scope, queue actions, editing, locking, and deletion.
Considerable work went into the browser's visual hierarchy, color treatment, spacing, and keyboard flow.
You can do quite a bit more in the browser:
- Chat scope. Open stashes from the current chat and press
gto switch to all chats. - Source metadata. Global entries show the source chat, workspace, timestamp, and short session ID.
- Search. Filter prompt text, chat names, workspaces, timestamps, queue mode, locks, and attachments.
- Queue draft. Press
qto place the selected stash in the composer as an editable/queuedraft. - Submit queue. Press
Shift+Qto prepend/queueand submit the selected stash while keeping the browser open for more. - Attachments. Restore images and collapsed large pastes with the prompt that owns them.
- Editing. Press
eto edit a stash with the configured editor or OMP's built-in editor. - Locking. Lock reusable stashes so deletion leaves them alone.
- Scoped deletion. Delete one unlocked stash or clear unlocked stashes from the current browser scope.
The browser starts on the current chat. Pressing g switches to all chats, back to the current chat, and back to all chats again.
Regular q comes first. It puts the stash into the composer as an editable /queue draft.
Shift+Q prepends /queue , submits the stash immediately, and keeps the browser open. Repeat it to stack messages in OMP's queue, then press Esc to exit.
Stash or clear any draft in the composer before restoring or submitting a saved prompt. This includes drafts that contain only images.
Search narrows the current scope as you type.
Images and large pasted bodies return with their stash.
Search for a stash, select it, and press e to edit it.
Locked stashes remain protected during bulk deletion.

Open /settings, choose Plugins, select @hkay-dev/ohmystash, and press Enter.
Available settings:
- Stash shortcut and Browser shortcut, with
noneto disable either one - Editor command, blank to use
$VISUAL,$EDITOR, or OMP's built-in editor - Browser layout: Automatic, Side by side, Stacked, or Compact
- Maximum body rows
- Time format: 12-hour or 24-hour
- Retention days:
0keeps stashes indefinitely - Dim background
- Background brightness (%)
- Background saturation (%)
- Show icons
Retention removes only expired, unlocked, normal stashes. Locked stashes, conflict copies, and recovery entries do not expire.
All the same settings are available from the CLI:
omp plugin config list @hkay-dev/ohmystash
omp plugin config set @hkay-dev/ohmystash "Browser layout" "Stacked"
omp plugin config set @hkay-dev/ohmystash "Retention days" 30
omp plugin config set @hkay-dev/ohmystash "Editor command" "code --wait"
omp plugin config set @hkay-dev/ohmystash "Dim background" false
omp plugin config delete @hkay-dev/ohmystash "Browser layout"OMS reloads plugin settings when a new OMP session starts.
I treated failed saves and missing stashes as bugs. OMS uses private atomic writes, file and directory fsync, attachment hashes, recoverable crash-window files, conflict copies, lock protection, and strict file checks.
The regression suite covers interrupted writes, concurrent saves and edits, corrupted attachments, symlinks, permissions, quota contention, recovery files, scoped deletion, source metadata, and retention.
I treated noticeable delay after a keypress as a bug. Safety checks stay enabled while OMS avoids repeated parsing, lowercasing, preview construction, attachment writes, and rendering work.

Stash files:
~/.omp/agent/prompt-stash/
Attachments:
~/.omp/agent/prompt-stash/attachments/
Limits:
- 1 MiB inline prompt text
- 64 MiB file-backed prompt body or individual attachment
- 128 MiB total attachments per stash
- 64 attachments per stash
- 2 MiB serialized stash metadata
- 256 normal active stashes
- 16 MiB normal metadata budget
Conflict copies and complete recovery files load outside the normal count and metadata caps. Attachments remain content-addressed for recovery and deduplication.
A separate filesystem backup is still required for hardware failure, filesystem corruption, or machine loss.
