Set up (or toggle) a macOS desktop banner that appears whenever Claude Code finishes a task, showing a one-line summary of what was done. Use when the user says "notify me when Claude is done", "desktop notification on completion", "set up the task banner", "mute the banner", or "unmute the banner".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# task-banner
Show a large, always-on-top desktop banner when Claude Code finishes a turn — with a one-line summary of what was actually completed. Works even when macOS Notification Center silently drops `osascript display notification` calls (a common problem: the CLI has no Notification Center registration, so the command exits 0 but nothing shows).
The banner is a borderless Cocoa overlay window drawn by `mac-overlay.js` (a JXA script adapted from [peon-ping](https://github.com/PeonPing/peon-ping)), so no notification permissions are needed.
## Requirements
- macOS (the overlay uses Cocoa via JXA / `osascript -l JavaScript`)
- Claude Code with hooks support
## Setup
1. Copy `mac-overlay.js` from this skill directory to `~/.claude/scripts/mac-overlay.js`.
2. Merge a `Stop` hook into `~/.claude/settings.json` (read the file first and preserve existing hooks):
```json
{
"hooks": {
"Stop": [
{
"matcher": "",
"hooks": [
{
"type": "command",
…Read the whole file at its exact version.
How to install
mdr add openclaudia/openclaudia-skills/task-banner@sha256:c499b11183aa5266The line at the top of this page pins the label git:20260717.77afd8e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
