dota2-hero-sounds

Dota 2 hero voice line notifications for Claude Code, OpenCode, and Pi. Get notified with voice lines from Axe, Crystal Maiden, Pudge, Zeus, and many more when your AI coding assistant completes tasks, hits errors, or needs your attention.

Quick Start

npx dota2-hero-sounds install

This auto-detects which tools you have installed and configures them. Use flags to target a specific tool:

npx dota2-hero-sounds install --claude     # Claude Code only
npx dota2-hero-sounds install --opencode   # OpenCode only
npx dota2-hero-sounds install --pi         # Pi only
npx dota2-hero-sounds install --all        # All three

How It Works

When events occur in your coding tool, a random hero speaks:

| Event | Category | Example Lines | |-------|----------|---------------| | Task complete | success | "Yes, Axe kills you!", "Burns, doesn't it?", "Told you a storm was coming!" | | Error | error | "An anchor around my neck!", "Okay, sure, I've made some mistakes.", "That was just a warm-up." | | Needs attention | attention | "Come to Pudge!", "Prepare thyself.", "Agony awaits." | | Session start | start | "Let the carnage begin!", "Storm Spirit is alive!", "Your God has arrived." |

A random sound is picked from the matching category each time. Sounds have a 3-second cooldown to prevent overlapping voice lines.

Hero Selection

By default, sounds are picked randomly from all heroes. You can set preferred heroes:

npx dota2-hero-sounds hero list          # Show available heroes with sound counts
npx dota2-hero-sounds hero set axe pudge # Only play Axe and Pudge sounds
npx dota2-hero-sounds hero show          # Show current preference
npx dota2-hero-sounds hero clear         # Reset to all heroes

Hero preferences are saved to ~/.config/dota2-sounds/config.json and take effect immediately — no reinstall needed. If a selected hero has no sounds for a category, it falls back to all heroes for that category.

Custom Sounds Directory

Point to your own sounds directory to fully replace the default Dota 2 voice lines:

npx dota2-hero-sounds sounds set /path/to/my-sounds
npx dota2-hero-sounds sounds show    # Show current setting
npx dota2-hero-sounds sounds clear   # Revert to default sounds

Your directory must contain the four category subdirectories (success/, error/, attention/, start/) with .mp3 files inside. Takes effect immediately — no reinstall needed.

You can also edit ~/.config/dota2-sounds/config.json directly:

{
  "heroes": [],
  "soundsDir": "/path/to/my-sounds"
}

CLI Commands

dota2-hero-sounds install       # Install hooks/plugins
dota2-hero-sounds uninstall     # Remove everything cleanly
dota2-hero-sounds test          # Play one sound per category
dota2-hero-sounds list          # Show all sounds by category
dota2-hero-sounds hero list     # Show heroes with per-category counts
dota2-hero-sounds hero set      # Set preferred heroes
dota2-hero-sounds sounds set    # Set custom sounds directory
dota2-hero-sounds sounds show   # Show current sounds directory
dota2-hero-sounds sounds clear  # Revert to default sounds
dota2-hero-sounds help          # Show help

What Gets Installed

Claude Code — Hooks added to ~/.claude/settings.json:

• Stop → plays success sound
• PostToolUseFailure → plays error sound
• Notification → plays attention sound
• SessionStart → plays start sound

OpenCode — Plugin written to ~/.config/opencode/plugins/dota2-sounds.js:

• session.status busy→idle transition → plays success sound
• session.error → plays error sound
• permission.asked → plays attention sound
• Plugin init → plays start sound (session.created fires too early)

Pi — Extension installed via pi install as a Pi package:

• session_start → plays start sound
• agent_end → plays success sound
• tool_execution_end (when isError) → plays error sound
• session_shutdown → plays error sound
• Attention sound not available — Pi has no permission/notification event

Uninstall

npx dota2-hero-sounds uninstall

This cleanly removes only the hooks/plugins added by this package — your other settings are untouched.

Adding Custom Sounds

You're not limited to Dota 2 voice lines — any .mp3 file works. Movie quotes, meme sounds, game SFX — drop them in and go.

The recommended approach is to use a custom sounds directory so your files aren't overwritten when you reinstall or update the package:

# Create your custom sounds directory with the required category folders
mkdir -p ~/my-dota-sounds/{success,error,attention,start}

# Copy the default sounds as a starting point
cp -r ~/.config/dota2-sounds/sounds/* ~/my-dota-sounds/

# Add your custom sounds
cp my-sound.mp3 ~/my-dota-sounds/success/

# Point the tool to your directory
npx dota2-hero-sounds sounds set ~/my-dota-sounds

Changes take effect immediately — no reinstall needed.

Warning: Files in the default sounds directory (~/.config/dota2-sounds/sounds/) are overwritten on every install or update. If you add sounds there directly, they will be lost. Use sounds set to point to your own directory instead.

If you're contributing to the project itself, add files to the source sounds/<category>/ directory and re-run dota2-hero-sounds install.

Note on hero selection: The hero set command only filters sounds that follow the Dota 2 naming convention (Vo_<hero>_*.mp3). Custom sounds without this prefix will be excluded when hero filtering is active. If your preferred heroes have no sounds for a category, all sounds (including custom ones) are used as a fallback.
