Start with: - `docs/index.mdx` for the overview - `docs/quickstart.mdx` to run the daemon - `docs/http-api.mdx` and `docs/cli.mdx` for API references Quickstart (local dev): ```bash sandbox-agent --token "$SANDBOX_TOKEN" --host 127.0.0.1 --port 2468 ``` Extract API keys from local agent configs (Claude Code, Codex, OpenCode, Amp): ```bash # Print env vars sandbox-agent credentials extract-env # Export to current shell eval "$(sandbox-agent credentials extract-env --export)" ```
