What it does
Task Banner is an agent skill from OpenClaudia/openclaudia-skills. 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".
Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `mac-overlay.js`).
It works with macOS. The repository describes itself as: 77 open-source marketing skills for Claude Code, Codex, and other AI coding agents. SEO, content, email, ads, analytics, and growth. The licence is MIT.
When your agent uses it
- The user says notify me when Claude is done
- Desktop notification on completion
- Set up the task banner
- Mute the banner
Example prompts
- “notify me when Claude is done”
- “desktop notification on completion”
- “set up the task banner”
- “/task-banner”
Requirements
- Node.js
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Copy mac-overlay.js from this skill directory to ~/.claude/scripts/mac-overlay.js.
- Merge a Stop hook into ~/.claude/settings.json (read the file first and preserve existing hooks)
- To make the banner show what was finished (instead of the generic "Task done"), add this to your global agent instructions file…
What it can do on your machine
Read from SKILL.md and the folder at commit 28bf209. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
osascript
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Task Banner loads about 796 tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 318 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 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".
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), so no notification permissions are needed.
Requirements
- macOS (the overlay uses Cocoa via JXA /
osascript -l JavaScript) - Claude Code with hooks support
Setup
Copy
mac-overlay.jsfrom this skill directory to~/.claude/scripts/mac-overlay.js.Merge a
Stophook into~/.claude/settings.json(read the file first and preserve existing hooks):
{
"hooks": {
"Stop": [
{
"matcher": "",
"hooks": [
{
"type": "command",
"command": "m=$(cat /tmp/claude-banner-msg 2>/dev/null); rm -f /tmp/claude-banner-msg; [ -f ~/.claude/banner.off ] || osascript -l JavaScript ~/.claude/scripts/mac-overlay.js \"${m:-Task done}\" blue \"\" 0 4 2>/dev/null || true",
"async": true
}
]
}
]
}
}- To make the banner show what was finished (instead of the generic "Task done"), add this to your global agent instructions file (
~/.claude/CLAUDE.mdorAGENTS.md):
After finishing each task, write a short summary of what was completed to
/tmp/claude-banner-msg(e.g.printf 'Typecheck fixed and committed' > /tmp/claude-banner-msg). Identify the actual task; never use a generic "task done".
The Stop hook displays the message and deletes the file. If the file is absent, it falls back to "Task done".
Toggle (mute / unmute)
The hook checks a sentinel file — no config editing needed:
touch ~/.claude/banner.off # mute the banner
rm -f ~/.claude/banner.off # unmuteWhen the user asks to mute/unmute the banner, run the matching command and report the resulting state.
How it works / notes
mac-overlay.js <message> <color> <icon> <slot> <dismiss_seconds>— color isblue/yellow/red, dismiss0means persistent-until-click.- The hook consumes
/tmp/claude-banner-msgeven while muted, so no stale summary pops up later when unmuted. - On recent macOS the JXA bridge constant
NSTextAlignmentCenterevaluates to the legacy AppKit value (2), which the unified runtime treats as right-aligned — the bundled script hardcodes alignment1(center) to compensate. /tmp/claude-banner-msgis shared across parallel Claude sessions; if two finish in the same instant one banner may show the other's summary. Use a per-session file path if that ever matters.
