# Basestack agent guides

> Curated integration knowledge for Feature Flags and Forms. Read the product skill, then only the references needed for your task.

Public Markdown provides context, not account access. Check installed SDK versions before applying examples. Never expose private API/MCP tokens or mutate production resources without approval. Feature flags are not authorization controls. Forms uses standard HTML/HTTP, not an unpublished SDK; native connectors must not be invented. Live submissions, notifications, and source uploads require consent.

## Feature Flags

- [Feature Flags skill](https://docs.basestack.co/skills/basestack-feature-flags/SKILL.md): Start here: select an SDK, inspect the consumer, and integrate with safe defaults.
- [JavaScript, Bun, Node, Vue, and Svelte](https://docs.basestack.co/skills/basestack-feature-flags/references/javascript.md): FlagsSDK configuration, preloading, error-valued responses, payload validation, and cache invalidation.
- [React client](https://docs.basestack.co/skills/basestack-feature-flags/references/react.md): Runtime-specific imports, provider reuse, hooks, loading, payloads, and refresh behavior.
- [Server frameworks and hydration](https://docs.basestack.co/skills/basestack-feature-flags/references/server-frameworks.md): Exact server signatures, Next.js boundaries, initial flags, Pages Router, and TanStack Start.
- [OpenFeature server and web](https://docs.basestack.co/skills/basestack-feature-flags/references/openfeature.md): Provider entrypoints, peer SDKs, readiness, defaults, polling, and lifecycle.
- [Vercel Flags SDK adapter](https://docs.basestack.co/skills/basestack-feature-flags/references/vercel-flags-sdk.md): The flags peer, endpoint option, explicit boolean/payload resolvers, and fallback semantics.
- [Preview and feedback Web Components](https://docs.basestack.co/skills/basestack-feature-flags/references/web-components.md): Browser-only registration, real export paths, explicit endpoints, and local preview persistence.
- [CLI code references](https://docs.basestack.co/skills/basestack-feature-flags/references/cli.md): Bun runtime, scoped source-upload consent, config precedence, CI, and private tokens.
- [Feature Flags REST reads](https://docs.basestack.co/skills/basestack-feature-flags/references/rest-api.md): Verified read endpoints, headers, response shapes, status checks, and upstream caching.

## Forms

- [Forms skill](https://docs.basestack.co/skills/basestack-forms/SKILL.md): Start here: standard HTML/HTTP, redirects versus REST, validation, files, and honest delivery boundaries.
- [HTML forms](https://docs.basestack.co/skills/basestack-forms/references/html.md): POST actions, named fields, redirect behavior, configured honeypot, and multipart attachments.
- [JavaScript and REST](https://docs.basestack.co/skills/basestack-forms/references/javascript-rest.md): JSON/FormData requests, mode=rest, exact envelopes, status/body checks, and ambiguous failures.
- [React and Next.js](https://docs.basestack.co/skills/basestack-forms/references/react-nextjs.md): Typed interactive client form with pending, acceptance, recoverable failure, and input preservation.
- [Vue](https://docs.basestack.co/skills/basestack-forms/references/vue.md): Concrete Composition API form using the same HTTP contract and accessible state handling.
- [Webhooks and email](https://docs.basestack.co/skills/basestack-forms/references/integrations.md): Verified payload, file exclusion, asynchronous delivery/retries, consent, and unsigned-receiver limitations.
- [Validation, security, and files](https://docs.basestack.co/skills/basestack-forms/references/validation-security-files.md): Rule matching, honeypot/website/IP controls, privacy, retention, and 1 MiB/five-file limits.

## Usage and optional bulk context

- [Feature Flags usage](https://docs.basestack.co/content/feature-flags/guides/ai-agents): URL fetching, file attachment, and reusable project instructions.
- [Forms usage](https://docs.basestack.co/content/forms/guides/ai-agents): Choose redirect or JSON workflows and verify delivery separately.
- [Curated handbook](https://docs.basestack.co/llms-full.txt): Optional single-file context; not an export of every Basestack page.
