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. Cross-skill operating rules that apply to every Twenty app task are in ../../references/concepts/operating-rules.md; they are authoritative and not restated per skill.

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. The About tab renders markdown text only: images and raw HTML are not rendered.
• 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 at https://docs.twenty.com before guessing. When a Twenty docs MCP server is configured (https://docs.twenty.com/mcp), prefer searching through it. That server is an optional enhancement, not a requirement for this skill.
