Publish App

When To Use

Pick this skill when the user wants to make an existing Twenty app presentable — listing copy, branding, public assets, and publication. Representative triggers:

• "prepare my Twenty app for the marketplace"
• "write the README for my Twenty app"
• "publish my app to npm"
• "add a logo / screenshots / marketplace metadata"
• "set up defineApplication marketplace fields"
• "review my app listing before going live"
• "ship a new version of my published app"

Do not use this skill to scaffold (use create-app), to change app entities (use develop-app), to deploy a private build to a specific Twenty server (use manage-app), or to query workspace records (use use-twenty-mcp).

Publishing Checklist

For background on how Twenty apps work — the SDK packages, remotes, sync lifecycle, and rendering model — read ../../references/concepts/how-apps-work.md.

Use ../../references/publish-app/prepare-for-app-store.md for detailed README, marketplace copy, logo, screenshot, and public asset guidance.

Keep the skill workflow concise:

• Inspect package.json, README.md, src/application-config.ts, and public/.
• For npm marketplace publication, ensure package.json has a valid bumped version and the twenty-app keyword.
• In defineApplication(), verify marketplace-facing fields such as displayName, description, author, category, logoUrl, screenshots, aboutDescription, websiteUrl, termsUrl, emailSupport, and issueReportUrl.
• Keep logoUrl and screenshots pointed at files in public/. Public assets must not contain secrets, private data, customer records, real tokens, or unreleased confidential material.
• Remember that if aboutDescription is omitted, the marketplace uses the package README.md from npm for the About content.
• Validate with yarn twenty dev:build; publish with yarn twenty app:publish or yarn twenty app:publish --tag <tag>.

Boundaries

Use $manage-app for remotes, deploys to a specific server, logs, troubleshooting, and CI/CD operations.

Use $develop-app when the app entities themselves need to change before the listing can be accurate.

Docs

If the needed publishing detail is unclear, search the official Twenty docs through the bundled twenty-docs MCP server before guessing.
