* Add Sandbox 1.0 migration skills
Refresh sandbox-sdk for @next and add sandbox-v1-migration plus
sandbox-2026-deprecation so agents install migrate paths from
cloudflare/skills instead of docs-only markdown.
* Split Sandbox skills by package line
Agents need separate build paths for stable and @next so they do
not mix incompatible exec models. Keep migration as its own
performable upgrade skill.
* Rename sandbox-sdk skill to sandbox-next
Pair build skills as sandbox-next and sandbox-stable so the
package line is obvious from the skill name.
* Restructure Sandbox skills as retrieval maps
Build skills gate the package line, state the contract, and
route to docs by task. Keep migrate as a stepwise port runbook.
* Clarify @next API file is a cheatsheet only
Point exhaustive reading at types and docs so agents do not
treat the process/terminal stub as the full Sandbox surface.
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agents.md research, biasing agents towards fetching official docs and examples rather than relying on potentially outdated training data.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.
