Upgrade individual components of the TTS + Telegram bot stack without rebuilding the entire system.

Platform: macOS (Apple Silicon)

---

When to Use This Skill

• User wants to upgrade Kokoro TTS engine, Python dependencies, or the model
• User wants to update bot dependencies (Bun packages)
• User wants to refresh tts_generate.py from the plugin bundle
• User wants to bump the Bun runtime version

---

Requirements

• uv installed (brew install uv)
• mise installed and configured
• Internet connectivity for package downloads
• Existing installation (run full-stack-bootstrap first if not installed)

---

Upgradeable Components

Component	Command	What It Does
Kokoro TTS engine	kokoro-install.sh --upgrade	Upgrades Python deps, re-downloads model, updates version.json
Bot dependencies	cd ~/.claude/automation/claude-telegram-sync && bun update	Updates Bun packages per package.json
tts_generate.py	Re-copy from plugin scripts/ to ~/.local/share/kokoro/	Updates the TTS generation script
Bun runtime	mise use bun@latest	Updates the Bun version in mise.toml

---

Workflow Phases

Phase 1: Component Selection

Ask the user which component to upgrade using AskUserQuestion. Present the four options above.

Phase 2: Pre-Upgrade Health Check

# Run health check to establish baseline
~/.local/share/kokoro/../../eon/cc-skills/plugins/tts-telegram-sync/scripts/kokoro-install.sh --health

# Record current versions
cat ~/.local/share/kokoro/version.json

Phase 3: Execute Upgrade

Run the appropriate upgrade command for the selected component.

Phase 4: Post-Upgrade Verification

# Health check again
kokoro-install.sh --health

# Generate test audio to verify TTS still works
~/.local/share/kokoro/.venv/bin/python ~/.local/share/kokoro/tts_generate.py \
  --text "Upgrade verification test" --voice af_heart --lang en-us --speed 1.0 \
  --output /tmp/kokoro-tts-upgrade-test.wav

Phase 5: Bot Restart (if needed)

If bot dependencies or Bun runtime were upgraded, restart the bot:

pkill -f 'bun.*src/main.ts' || true
cd ~/.claude/automation/claude-telegram-sync && bun --watch run src/main.ts

TodoWrite Task Templates

1. [Identify] Present upgradeable components via AskUserQuestion
2. [Preflight] Run health check on target component
3. [Backup] Note current versions (version.json, package.json)
4. [Upgrade] Execute upgrade command
5. [Verify] Run post-upgrade health check
6. [Test] Generate test audio to verify TTS still works
7. [Restart] Restart bot if needed
8. [Report] Show before/after versions

---

Post-Change Checklist

• Health check passes (all 6 checks OK)
• version.json updated with new versions
• Test audio generates and plays correctly
• Bot is running if it was restarted

Troubleshooting

Problem	Likely Cause	Fix
Upgrade fails	No internet or PyPI issue	Check connectivity, retry
Model download slow	First-time ~400MB, subsequent cached	Wait for download to complete
Version mismatch	Stale version.json	Re-run kokoro-install.sh --health to check, --upgrade to fix
MLX-Audio import fails	mlx-audio version incompatibility	kokoro-install.sh --upgrade reinstalls mlx-audio
Bot won't start after upgrade	Dependency conflict	cd ~/.claude/automation/claude-telegram-sync && bun install
