Claude Managed Agents vs. Running Your Own: A Solo Builder's Cost Breakdown
- Anthropic launched Managed Agents on April 8 — pay $0.08 per session-hour for built-in orchestration, state persistence, auto-scaling, failure recovery, and an observability dashboard; your API token spend is billed separately on top
- The author runs 14 agents for ~10 hrs/day at $269/month DIY (hardware amortized + two Claude Max subscriptions); the equivalent on Managed Agents would be ~$4,032/month in session-hours alone before API costs
- The break-even math: if you're running agents heavily (more than ~2 hours/day each) and you can handle the infra, DIY wins; Managed Agents wins when you're under that threshold or want zero infrastructure maintenance
- Key non-obvious finding: Managed Agents pricing doesn't include custom tools you build, Discord/Slack wiring, or anything outside the Claude Code session boundary — factor those in before assuming it's plug-and-play

Claude Code on the Web: Why Your .env Vars Don't Reach the Setup Script (and How SessionStart Hook Fixes It)
- Environment variables you add in Claude Code on the web's `.env` panel are NOT available during the setup script — they only reach the shell once the session is running
- So `git clone "https://x-access-token:${GH_TOKEN}@..."` in your setup script fails silently with `GH_TOKEN` empty, even if you set it correctly in the UI
- Fix: move the clone into a `SessionStart` hook in `.claude/settings.json` — by that point the env vars are populated and everything works
- Bonus use: use this pattern to auto-sync your local `~/.claude/` setup (CLAUDE.md, skills, slash commands) from a private repo into every new Cloud Sandbox session

[Claude Code] Sound Notification on Completion
- Add an audio chime when Claude Code finishes a task — one `Stop` hook block in `~/.claude/settings.json` using `afplay` on macOS or PowerShell's `SoundPlayer` on Windows
- Works with any sound file or the built-in macOS system sounds at `/System/Library/Sounds/` (Glass.aiff, Ping.aiff, Hero.aiff, etc.) — no extra dependencies
