Description

Current SDK guides and offline fixture instructions still directed users to removed CLI commands or the retired manual MCP deployment artifact. Update them to the supported source acquisition/deployment path and actual generated Sandbox MCP service.

Type of Change

• 📖 Documentation
• 🧪 Tests

Changes

Refresh bilingual authoring/lifecycle/MCP examples and source-download error remediation. Preserve the publishing-source/fixture boundary and version-labeled historical captures. Existing fixture guards now require list/init; the fixture notice remains explicit. SDK fetching, execution, authentication and cleanup behavior are unchanged.

CLI contract: Alibaba-Agent-Sandbox/agent-sandbox#247.

Testing

• Final Python3.10/3.11/3.12 matrix and package-build gates pass.
• Template index: 35 passed; fixture suite: 37 passed, one skipped.
• Remote Ruff/format/Mypy checks and hygiene/link checks pass.
• Real public runtime fixtures (python-hello/agents-cli), pinned public contract and Python-to-Node engine CI checks pass.

The first matrix exposed stale fixture-documentation guards, which were corrected. A later Python3.11 run failed on an unchanged process test reading an empty PID marker; its failure is retained; one rerun of that unchanged job passed. No assertion or dependency was weakened.

Checklist

• Conventions, existing translations, CHANGELOG and fixture boundaries preserved.
• No credentials included; no package version changed.

Definition of Done

• Final complete remote test/build gates pass.
• Relevant real runtime/filesystem components checked; no cloud resources created locally.
• Owner note/evidence, bilingual docs and CHANGELOG included.
• Repository health and hygiene pass.
