Claudio

June 2, 2026 ยท View on GitHub

Claudio is a hook-driven audio layer for coding agents. It listens to hook events from Claude Code and OpenAI Codex CLI, maps the event to a contextual sound, and plays that sound without making the agent wait for playback.

It can play different sounds for tool starts, tool successes, tool failures, prompts, notifications, completions, compaction, session starts, and subagent events. Bash commands are parsed, so git commit, npm test, and go build can each have their own sounds instead of sharing one generic shell sound.

Full documentation starts at docs/index.md.

Install

go install claudio.click/cmd/claudio@latest

Install hooks for Claude Code:

claudio install --agent claude --scope user

Install hooks for Codex:

claudio install --agent codex --scope user

After Codex hook installation, run /hooks in Codex and trust the Claudio hook. Use --scope project instead of --scope user when you want hooks only for the current repository.

Daily Commands

claudio status
claudio volume 0.4
claudio mute
claudio unmute
claudio uninstall --agent claude --scope user

Optional agent command artifacts:

claudio install-commands --agent claude       # /claudio in Claude Code
claudio install-commands --agent codex        # $claudio skill in Codex
claudio install-commands --agent antigravity  # Antigravity skill and CLI command

Soundpacks

Claudio ships platform defaults and supports three custom soundpack forms:

  • Directory soundpacks under loading/, success/, error/, interactive/, completion/, and system/
  • JSON soundpacks that map Claudio sound keys to files anywhere on disk
  • Managed git soundpacks installed with claudio soundpack add

Useful commands:

claudio soundpack list
claudio soundpack init my-pack --from-platform
claudio soundpack validate ./my-pack.json
claudio soundpack install ./my-pack.json --default
claudio soundpack add gh:owner/repo --name my-pack --default
claudio soundpack update --all

Supported audio formats are WAV, MP3, and AIFF. See docs/soundpacks.md for layout, fallback chains, JSON mappings, validation, and git-backed soundpacks.

Tracking

Sound tracking is enabled by default. Claudio records resolved sounds and missing fallback candidates in a SQLite database under the XDG cache directory, then exposes that data through:

claudio analyze usage --show-summary --show-chains
claudio analyze missing --preset last-week

Use these reports to decide which sounds your custom pack should add next.

Build And Test

go build ./cmd/claudio
