form-validation

form-validation is a cursor rule for Cursor from airweave-ai/airweave. It costs 0 tokens per session (1,323 once invoked), scanned A, original, MIT.

A set of lightweight form-validation rules that gives users brief hints while they type or leave a field. It checks values such as names, URLs, email addresses, API keys, and repository names.

In plain words
What is it for?
Use it when adding or updating validated form fields, including GitHub, Stripe, Bitbucket, collection, connection, URL, email, and API-key inputs.
Why use it?
It catches common input mistakes early while avoiding blocking behavior and harsh error messages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

form-validation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Airweave Validation System

Philosophy

Minimal, non-intrusive validation that guides without blocking. No success messages or harsh errors, just essential hints.

Core Components

ValidatedInput Component

  • Replaces standard inputs with validation-aware inputs
  • Shows hints after debounce delay (typically 500ms)
  • Immediate validation on blur for some fields
  • Subtle 30% opacity border colors
  • Real-time feedback during typing (not just on submit)

Validation Rules (lib/validation/rules.ts)

General Validators
  • collectionNameValidation: 4-64 characters
  • sourceConnectionNameValidation: 4-42 characters
  • urlValidation: Must start with http:// or https://
  • emailValidation: Basic format check
  • apiKeyValidation: Detects placeholder text, shows on change with 500ms debounce
Source-Specific Validators

GitHub

  • githubTokenValidation: Validates format (ghp_, github_pat_, or 40-char hex)
  • repoNameValidation: Enforces owner/repo format (e.g., "airweave-ai/airweave")

Stripe

  • stripeApiKeyValidation: Checks for sk_test_ or sk_live_ prefix, min 20 chars

Bitbucket

  • workspaceValidation: Alphanumeric + hyphens + underscores
  • repoSlugValidation: Alphanumeric + hyphens + underscores + dots

PostgreSQL/Databases

  • databaseHostValidation: Rejects protocol prefixes (http://, postgresql://, etc.)
  • databasePortValidation: Validates 1-65535 range, rejects non-numeric strings
  • databaseTablesValidation: Accepts "*" or comma-separated table names

Auth Providers

  • clientIdValidation: Generic client ID validation
  • clientSecretValidation: Generic client secret validation
  • authConfigIdValidation: For Composio config IDs
  • accountIdValidation: For auth provider account IDs
  • projectIdValidation: For Pipedream project IDs
  • environmentValidation: For environment fields

Usage

Basic Usage

import { ValidatedInput } from '@/components/ui/validated-input';
import { collectionNameValidation } from '@/lib/validation/rules';

<ValidatedInput
  value={name}
  onChange={setName}
  validation={collectionNameValidation}
  placeholder="Enter name"
  className="..."
/>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
