chore: add Agent Skills by reidbarber · Pull Request #9515 · adobe/react-spectrum

reidbarber · 2026-01-23T23:46:09Z

Related to #9508.

Adds a script to generate Agent Skills based on our documentation.

This yarn generate:skills script uses our existing markdown docs build output, and copies/formats them to match the Agent Skills spec. The script outputs these into our docs build in the .well-known/ directory.

Users will be able to install them by via npx skills:

npx skills add https://react-spectrum.adobe.com
npx skills add https://react-aria.adobe.com

✅ Pull Request Checklist:

Included link to corresponding React Spectrum GitHub Issue.
Added/updated unit tests and storybook for this change (for new code or code which already has tests).
Filled out test instructions.
Updated documentation (if it already exists for this component).
Looked at the Accessibility Practices for this feature - Aria Practices

📝 Test Instructions:

Try running these in any project:

React Spectrum (S2):

npx skills add https://d1pzu54gtk2aed.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/

React Aria:

npx skills add https://d5iwopk28bdhl.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/

The skills should get placed in the current project.

Check the new /ai docs pages:

React Aria: https://d5iwopk28bdhl.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/ai
React Spectrum: https://d1pzu54gtk2aed.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/ai

Verify the old /mcp links now redirect to the /ai mcp section:

React Aria: https://d5iwopk28bdhl.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/mcp
React Spectrum: https://d1pzu54gtk2aed.cloudfront.net/pr/94a22af3fcd09be55c2614e05cdfb7730361d00f/mcp

and verify the old mcp pages aren't visible in search or in the sidebar.

do we need to commit these or can we deploy them as part of the docs build?

reidbarber · 2026-01-26T20:13:07Z

@devongovett I think the other options are:

Publish a custom CLI tool (run via npx) that pulls from docs CDN and places skills in the user's current directory
Include a setup.sh script in the rules directory that that pulls from docs CDN

I guess the setup.sh solution requires the least maintenance, but requires some extra work on the user's end.

reidbarber · 2026-01-29T23:50:25Z

Discussed with the team, and it seems like we're leaning towards this solution:

We release an Artifact with the zipped markdown docs each release.
Have our skills include a script that downloads and unzips that (optionally, use the user's installed version?)

reidbarber · 2026-01-30T00:09:27Z

Just noticed that npx skills added support for well-known vercel-labs/skills#138

so we might be able to just deploy these to the CDN and have them be installed that way.

This reverts commit 62b2283.
