Claude uses these on its own when your request matches.

• blob-storageUse when a val needs simple key/value persistence — JSON documents, cached responses, uploaded files, or binary assets. Covers the std/blob API, listing and deleting keys, account-global or val scoping, and storage limits.
• client-side-jsUse when a val needs to ship JavaScript that runs in the browser — React apps, vanilla DOM scripts, canvas/games, htmx/Alpine, or any client-side module beyond a single inline snippet. Explains how Val Town serves transpiled .ts/.tsx/.jsx modules with no build step, how the…
• create-skillUse when the user wants to persist a preference, skill, or knowledge. Use when it would aid future val development to store a memory of how best to build something.
• cron-and-intervalsUse when building a val that runs on a schedule — periodic jobs, recurring tasks, polling, cron jobs, monitoring, alerting. Covers the interval handler signature, cron expressions, the UTC timezone constraint, and the `lastRunAt` pattern for detecting new items since the…
• emailUse when a val sends email, receives email, or is triggered by an incoming email. Covers email-type vals (the Email handler shape, attachment limits, the assigned val email address) and sending mail via std/email.
• http-endpointsUse when building an HTTP val — a web endpoint, API route, webhook receiver, or any val that responds to HTTP requests. Covers the handler signature, Hono usage, the endpoint URL, CORS behavior, redirects, and Val Town-specific limitations.
• oauthUse when a val needs to require login with a Val Town account — gating routes behind authentication, identifying the current user, building user-specific dashboards. Covers std/oauth's `oauthMiddleware` and `getOAuthUserData`, the auto-managed `/auth/*` routes, and session…
• react-uiUse when building any val with a user interface — dashboards, web apps, landing pages, forms, admin tools, anything users see in a browser. Covers JSX/React conventions, Twind/Tailwind styling, React version pinning, the view-source link requirement, and what to avoid…
• restricted-accessUse when a val's HTTP endpoints should not be open to the whole internet — limiting an app to a team, understanding why an endpoint redirects to a login page, letting a webhook through, or identifying which Val Town user is viewing an app. Covers app access (`httpPrivacy`), org…
• sqlite-storageUse when a val needs to store structured or relational data. Covers the std/sqlite API, parameterized queries, transactions, and the val-scoped vs organization-scoped database distinction.
• third-party-integrationsUse when a val talks to an external service — Slack, Discord, Telegram, Stripe, GitHub, Gmail, Google Sheets, Postgres/Supabase/Upstash/Neon, browser automation (Playwright, Browserbase, Kernel, Steel), web scraping, PDF generation, push notifications, RSS, or any other…
