- fix floating promise in streaming concatenation example (contradicted own rules)
- add base URL note for relative Retrieve paths in rules.md
- generalize implements-vs-extends anti-pattern to all platform base classes
- deduplicate review.md anti-pattern table (points to SKILL.md instead)
- expand code categorization step with per-category check guidance
- add CPU time limit awareness rule
- fix vague ~6 months threshold in compat date rule
Add new sandbox-sdk skill for building secure code execution environments on Cloudflare. The skill follows the retrieval-led reasoning approach from the Vercel agents.md research, biasing agents towards fetching official docs and examples rather than relying on potentially outdated training data.
- Add sandbox-sdk skill with core patterns, wrangler config, and API guidance
- Include references for detailed API signatures and example mappings
- Add retrieval-first section to durable-objects skill with doc URLs
- Update README with sandbox-sdk in skills table
The sandbox-sdk skill covers getSandbox lifecycle, exec vs runCode decisions, file operations, Dockerfile extensions, preview URLs, and anti-patterns.
