Start with a bounded tool
Choose an editor extension, platform plugin, skill, or agent role. Explain its inputs, output, permissions, and supported versions. Start from the greeting worker when learning the protocol.
ContinuePublish a tool someone can trust.
Turn a useful PlayWeld extension into a clear listing, a versioned package, and a maintainable release.
Check the package contract
Use the correct root manifest and a versioned archive. Review capabilities and dependencies; a valid archive alone does not demonstrate desktop runtime compatibility.
ContinuePrepare an honest listing
Create an account, verify your email, and write an original summary and installation guide. Include a license, source link, compatibility range, and the checks you actually ran.
ContinueUpload and review
Upload a release through the publisher workspace. The site inspects package metadata and archive paths. Submit for review and respond to any packaging or content corrections.
ContinueMaintain the release
Use a new version for changed package bytes. Describe changes and upgrade steps, keep requirements current, and use the creator workspace to review feedback and downloads.
ContinueTry the worker before publishing
Extract the Greeting Starter archive, open a terminal in that directory, and run the command below. Paste each JSON request as a separate line. Initialization announces the tool, the call returns a greeting, and shutdown ends the exercise.
node index.cjs
{"jsonrpc":"2.0","id":1,"method":"plugin/initialize","params":{"protocolVersion":1}}
{"jsonrpc":"2.0","id":2,"method":"plugin/tool/call","params":{"toolId":"playweld.greeting/greet","input":{"name":"Builder"},"context":{"taskId":null,"agentRole":null,"accessMode":"restricted"}}}
{"jsonrpc":"2.0","id":3,"method":"plugin/shutdown","params":{}}
Compare the response with your intended output and test invalid input too. This standalone exercise does not establish desktop sandbox availability. Keep packaging checks, worker behavior, and desktop acceptance as separate evidence.
A useful release checklist
- State supported PlayWeld and engine versions.
- Explain filesystem, network, and model access.
- Include source, license, and reproducible checks.
- Describe installation, rollback, and any limitations.
- Keep screenshots and examples free of private project data.
