claude-meseeks 🔵
"I'm Mr. Meeseeks! Look at me!"
A Claude Code plugin that plays a Mr. Meeseeks voice line
whenever Claude is genuinely waiting on you.
When Claude finishes and is waiting for your next prompt → a satisfied/finished clip
from audio/done/ ("All done!", "Ooh yeah!", "Yes siree!" …).
When Claude needs your approval → an asking/coaching clip from audio/asking/
("Can you help me?", "You mind if we get back to the task?" …).
Both are driven by the Notification event, filtered by notification_type so it fires
only when you're actually needed. Autonomous work — auto-accept/bypass-permissions runs,
background-agent and subagent activity, auth refreshes — stays silent. Clips are random
within the category, and playback is detached and non-blocking, so a long line never freezes
your prompt.
Install
This repository is both the plugin and its own marketplace.
Or, from a local clone:
Restart or reload Claude Code and finish a turn — you should hear Meeseeks.
Requirements
An audio player on your PATH. The tool auto-detects, in order:
afplay (macOS, built in) → ffplay → mpg123 → paplay → aplay → Windows PowerShell
Media.SoundPlayer. On macOS nothing extra is needed. On Linux, install ffmpeg
(for ffplay) or mpg123.
No Go toolchain is required to use the plugin — prebuilt binaries ship in bin/. Go is
only needed to rebuild them (see below).
The meeseeks CLI
Playback is handled by a small Go program, meeseeks, with the clips embedded directly in
the binary. You can drive it by hand too:
How it works
hooks/hooks.json registers Notification and UserPromptSubmit hooks that both run
scripts/play.sh notify. That launcher execs the prebuilt bin/meeseeks-<os>-<arch> for
your platform (falling back to go build from source if there's no matching binary, or
staying silent if neither is available), passing the event's JSON through on stdin.
meeseeks notify reads that JSON and looks at hook_event_name and notification_type:
The chosen clip is extracted from the embedded audio to a cache dir and handed to a system
player in a detached process. Every path exits 0, so the hook never blocks or errors your
session.
Each category can be silenced independently via the plugin's config options
(enableDone / enableAsking / enableFeedback) — Claude Code prompts for these when you
enable the plugin, and passes them to the hook as CLAUDE_PLUGIN_OPTION_* env vars. They
default to on; only automatic hook playback is gated (manual meeseeks play always plays).
Why not the Stop hook? Stop fires at the end of every turn — including
auto-continuations — so it plays sounds when you aren't actually being waited on. The
event-type filter is the reliable signal for "it's your turn."
Customizing clips
Clips live under audio/, sorted into three folders that map to behavior:
audio/done/ — played when Claude finishes and it's your turn (idle prompt).
audio/asking/ — played on permission/input prompts.
audio/feedback/ — played every time you submit a prompt to Claude.
To change what plays, move .mp3 files between the folders or drop your own in, then
rebuild the binaries so the new clips are re-embedded:
Two constraints: filenames must end in .mp3, and — because of a go:embed restriction —
must not contain apostrophes (').
Why Meeseeks? On single-purpose sessions
The theme isn't just a joke — it's a working philosophy.
A Mr. Meeseeks is summoned to accomplish one task. It exists only until that task is
done, and then it poofs out of existence, satisfied. Give a Meeseeks a single, concrete goal
("help me finish this putt") and it's cheerful and effective. Give it a vague or unbounded
one, or keep it alive long past its purpose, and things degrade fast — "existence is
pain, Jerry!" — until you get a room full of increasingly unhinged Meeseeks.
A Claude Code session works best the same way:
Summon it for one goal. A session scoped to a single, well-defined objective —
"add this endpoint", "fix this failing test", "write this plugin" — is focused and sharp,
the same way a fresh Meeseeks is.
Let it finish, then let it go. When the goal is met, end the session. Start a new one
for the next task. A fresh session with a clean context beats a stale one every time.
Beware the long-lived session. Dragging one conversation across many unrelated goals
is how you get the Meeseeks box problem: context piles up, focus drifts, earlier tangents
pollute later work, and quality slides. Long ≠ productive.
So: treat each session like a Meeseeks. One purpose. Accomplish it. Poof. 🔵
