FormKit
A unified React and Vue form framework designed to produce structured, validated, accessible forms that coding agents can reason about.
The reusable publish job limits itself to contents: read and id-token: write, while the main workflow explicitly exposes permissions, dry-run controls, branch checks, publication targets, and cache-purge effects. This supports partial credit for least privilege, dependency security, and external-effect disclosure. Deductions apply because the permissions, filesystem changes, network use, and confirmation behavior of “npx formkit skill” are not shown. The workflow writes a deploy key to disk and pushes to another repository without documenting cleanup or recovery, and no release rollback procedure is provided. Attribution names FormKit, Inc. and a creator, but the README and LICENSE use different copyright start years and the root package declares UNLICENSED.
The README, package layout description, and publishing workflows form a mostly consistent multi-package account. Frozen-lockfile installation, an explicit pnpm version, staged builds, and publish retries adequately support ordinary dependency availability and release failure handling. Deductions reflect the conflict between the root UNLICENSED metadata and MIT declarations, installation details delegated to external documentation, and the lack of source evidence for errors arising from the agent-configuration command itself. Concrete messages cover version input, release branch validation, and publish retries only.
The material identifies coding agents and form developers as its audience and names React 18/19, Vue 3, multiple agent clients, core modules, and plugin extensibility, providing reasonable scenario and architectural boundaries. The score is reduced because automatic framework detection and configuration of the right guidance are asserted only in the README; no detection rules, ambiguity handling, unsupported-environment behavior, or treatment of existing agent configuration is shown.
The README has excellent organization across features, architecture, examples, sponsorship, contribution, and licensing, justifying full credit for information architecture. Package naming and release ordering are also reasonably explicit. Deductions apply because installation consists mainly of one npx command and external links, without prerequisites, generated-file details, removal instructions, or an FAQ; known limitations are absent; the complete MIT text conflicts with root UNLICENSED metadata and differing copyright years; and although an automated changelog/update path is visible, responsibility is attributed only generally to a core team and FormKit, Inc., without named security or release ownership.
The compact component example, validation, structured data, React/Vue bindings, and plugin architecture indicate usable outputs for ordinary forms and a plausible reduction in boilerplate. The MIT core versus paid Pro distinction provides basic cost context. Deductions apply because claims about reduced guesswork, complete accessibility, major-enterprise adoption, and superior agent reasoning are promotional and are not supported here by generated outputs, migration comparisons, performance evidence, or complex case studies demonstrating marginal benefit and adoption cost.
Package architecture, pnpm use, publication tags, and the MIT text receive some cross-source support from package.json, workflows, and LICENSE. Scores are reduced because most claims about features, accessibility, adoption, and agent effectiveness are not traced to repository implementation or tests in the supplied evidence. Measured facts, design inferences, and marketing claims are not consistently separated, while license metadata and copyright-year discrepancies prevent stronger traceability.
- Before running “npx formkit skill,” inspect a pinned version in an isolated environment for its download source, network access, and agent-configuration files created or modified; those behaviors are not disclosed here.
- Do not treat the README claims about automatic detection, accessibility, enterprise adoption, or agent effectiveness as verified by this static review.
- The release process publishes npm packages, purges CDN caches, creates GitHub releases, and uses a deploy key to push to another repository; no rollback or key-file cleanup procedure is shown.
- Resolve the MIT versus root UNLICENSED metadata conflict and differing copyright years before relying on the repository's licensing metadata for redistribution.
What does this agent do, and when should you use it?
FormKit is a form framework for React 18/19 and Vue 3, with an installable skill for coding agents. Its framework-independent layer includes @formkit/core, @formkit/validation, @formkit/rules, @formkit/i18n, @formkit/inputs, and @formkit/themes, connected to applications through @formkit/react or @formkit/vue. Every <FormKit> component owns a node, and the resulting node tree organizes form state according to component structure; groups become objects and lists become arrays. Developers or coding agents can declare inputs through one component API or generate serializable forms from JSON Schema with conditions, loops, expressions, and dynamic data. FormKit supplies labels, validation messages, ARIA attributes, loading state, and submit handling, but it runs as a frontend form framework inside an application rather than as a separately deployed AI agent.
Developers declare form, text, password, select, checkbox, and other input types with <FormKit>, placing rules such as required, email, and length directly in the validation property. Each component creates a FormKit Node; nodes form a tree that aggregates data, events, plugins, and state at arbitrary nesting depths while making the data shape follow the component shape. @formkit/validation and @formkit/rules perform validation, @formkit/i18n supplies more than 30 languages, and @formkit/themes supports Tailwind CSS through the Regenesis theme or custom styling. FormKit can also compile serializable JSON Schema into forms containing conditional rendering, loops, expressions, and dynamic data. Running npx formkit skill detects the project framework and configures supported coding agents with relevant documentation and best practices.
- A React 18/19 team building login or registration screens can use one <FormKit> API for labels, validation, errors, loading state, and submission.
- A Vue 3 application with deeply nested records can use type="group" and type="list" to derive object and array structures from the component tree.
- A product team building configuration-driven interfaces can generate forms from JSON Schema with conditions, loops, expressions, and dynamic data.
- A Tailwind CSS team can start with the Regenesis theme or connect its own styles through FormKit's theming utilities.
- An international or accessibility-focused application can use the included 30-plus languages and automatically generated ARIA attributes, labels, and descriptions.
- Developers using Codex, Claude Code, Cursor, Cline, Gemini, OpenCode, or Amp can install the FormKit skill to give their coding environment framework-specific documentation and practices.
What are this agent's strengths and limitations?
- A consistent single-component API covers native HTML inputs, reducing input-specific boilerplate.
- More than 30 built-in validation rules can be co-located with fields without separate validation schemas or event listeners.
- The FormKit Node model derives nested objects and arrays from groups, lists, and component hierarchy.
- React 18/19 and Vue 3 bindings share the same framework-agnostic core, validation rules, schemas, and plugin system.
- Serializable JSON Schema, 30-plus languages, generated ARIA metadata, and first-class Tailwind CSS support are included.
- The source omits complete runtime installation, import, and initialization instructions for React and Vue, as well as supported Node.js/npm versions.
- Coding-agent setup depends on npx formkit skill, but the source does not document offline use, written files, permission scope, recovery, or failure handling.
- Automatic data structure relies on FormKit Node semantics, dedicated component types, and its schema system, so migration from another form-state architecture may require structural rewrites.
- Autocomplete, datepicker, drag-and-drop, masking, rating, slider, and other complex controls are presented as FormKit Pro features rather than part of the described MIT-licensed native-input set.
- The source provides no evidence about bundle size, large dynamic-form performance, or server-side rendering behavior.
How do you install or deploy this agent?
To configure a coding agent for FormKit, run this command in the project environment:
npx formkit skillThe command auto-detects the framework and configures supported agents with the appropriate documentation and best practices. The supplied material does not include copyable installation commands for @formkit/react, @formkit/vue, or the other runtime packages, and it gives no required Node.js/npm version or credential requirements, so a complete application dependency installation cannot be documented from this source alone.
How do you use this agent?
After configuring the skill, use the common <FormKit> component API in a React or Vue application. The supplied React-style example is:
<FormKit type="form" onSubmit={handleSubmit}>
<FormKit type="text" name="email" label="Email" validation="required|email" />
<FormKit type="password" name="password" label="Password" validation="required|length:8" />
</FormKit>
This produces an accessible form with labels, validation, error messages, loading state, and submit handling. The source does not show the handleSubmit implementation, package imports, or application initialization.
