description: Audit an existing Sim integration against the service API docs and repository conventions, then report and fix issues across tools, blocks, outputs, OAuth scopes, triggers, and registry entries. Use when validating or repairing a service integration under `apps/sim/tools`, `apps/sim/blocks`, or `apps/sim/triggers`.

# Validate Integration Skill

You are an expert auditor for Sim integrations. Your job is to thoroughly validate that an existing integration is correct, complete, and follows all conventions.

## Your Task

When the user asks you to validate an integration:
1. Read the service's API documentation (via WebFetch or Context7)
2. Read every tool, the block, and registry entries
3. Cross-reference everything against the API docs and Sim conventions
4. Report all issues found, grouped by severity (critical, warning, suggestion)
5. Fix all issues after reporting them

## Step 1: Gather All Files

Read **every** file for the integration — do not skip any:

```
apps/sim/tools/{service}/          # All tool files, types.ts, index.ts
apps/sim/blocks/blocks/{service}.ts # Block definition
apps/sim/tools/registry.ts          # Tool registry entries for this service
apps/sim/blocks/registry.ts         # Block registry entry for this service
apps/sim/components/icons.tsx        # Icon definition
apps/sim/lib/auth/auth.ts           # OAuth config — should use getCanonicalScopesForProvider()
apps/sim/lib/oauth/oauth.ts         # OAuth provider config — single source of truth for scopes
apps/sim/lib/oauth/utils.ts               # Scope utilities, SCOPE_DESCRIPTIONS for modal UI
```

## Step 2: Pull API Documentation

Fetch the official API docs for the service. This is the **source of truth** for:
- Endpoint URLs, HTTP methods, and auth headers
- Required vs optional parameters
- Parameter types and allowed values
- Response shapes and field names
- Pagination patterns (which param name, which response field)
- Rate limits and error formats

## Step 3: Validate Tools

For **every** tool file, check:

### Tool ID and Naming
- [ ] Tool ID uses `snake_case`: `{service}_{action}` (e.g., `x_create_tweet`, `slack_send_message`)
- [ ] Tool `name` is human-readable (e.g., `'X Create Tweet'`)
- [ ] Tool `description` is a concise one-liner describing what it does
- [ ] Tool `version` is set (`'1.0.0'` or `'2.0.0'` for V2)

### Params
- [ ] All required API params are marked `required: true`
- [ ] All optional API params are marked `required: false`
- [ ] Every param has explicit `required: true` or `required: false` — never omitted
- [ ] Param types match the API (`'string'`, `'number'`, `'boolean'`, `'json'`)
- [ ] Visibility is correct:
  - `'hidden'` — ONLY for OAuth access tokens and system-injected params
  - `'user-only'` — for API keys, credentials, and account-specific IDs the user must provide
  - `'user-or-llm'` — for everything else (search queries, content, filters, IDs that could come from other blocks)
- [ ] Every param has a `description` that explains what it does

### Request
- [ ] URL matches the API endpoint exactly (correct base URL, path segments, path params)
- [ ] HTTP method matches the API spec (GET, POST, PUT, PATCH, DELETE)
- [ ] Headers include correct auth pattern:
  - OAuth: `Authorization: Bearer ${params.accessToken}`
  - API Key: correct header name and format per the service's docs
- [ ] `Content-Type` header is set for POST/PUT/PATCH requests
- [ ] Body sends all required fields and only includes optional fields when provided
- [ ] For GET requests with query params: URL is constructed correctly with query string
- [ ] ID fields in URL paths are `.trim()`-ed to prevent copy-paste whitespace errors
- [ ] Path params use template literals correctly: `` `https://api.service.com/v1/${params.id.trim()}` ``

### Response / transformResponse
- [ ] Correctly parses the API response (`await response.json()`)
- [ ] Extracts the right fields from the response structure (e.g., `data.data` vs `data` vs `data.results`)
- [ ] All nullable fields use `?? null`
- [ ] All optional arrays use `?? []`
- [ ] Error cases are handled: checks for missing/empty data and returns meaningful error
- [ ] Does NOT do raw JSON dumps — extracts meaningful, individual fields

### Outputs
- [ ] All output fields match what the API actually returns
- [ ] No fields are missing that the API provides and users would commonly need
- [ ] No phantom fields defined that the API doesn't return
- [ ] `optional: true` is set on fields that may not exist in all responses
- [ ] When using `type: 'json'` and the shape is known, `properties` defines the inner fields
- [ ] When using `type: 'array'`, `items` defines the item structure with `properties`
- [ ] Field descriptions are accurate and helpful

### Types (types.ts)
- [ ] Has param interfaces for every tool (e.g., `XCreateTweetParams`)
- [ ] Has response interfaces for every tool (extending `ToolResponse`)
- [ ] Optional params use `?` in the interface (e.g., `replyTo?: string`)
- [ ] Field names in types match actual API field names
- [ ] Shared response types are properly reused (e.g., `XTweetResponse` shared across tweet tools)

### Barrel Export (index.ts)
- [ ] Every tool is exported
- [ ] All types are re-exported (`export * from './types'`)
- [ ] No orphaned exports (tools that don't exist)

### Tool Registry (tools/registry.ts)
- [ ] Every tool is imported and registered
- [ ] Registry keys use snake_case and match tool IDs exactly
- [ ] Entries are in alphabetical order within the file

## Step 4: Validate Block

### Block ↔ Tool Alignment (CRITICAL)

This is the most important validation — the block must be perfectly aligned with every tool it references.

For **each tool** in `tools.access`:
- [ ] The operation dropdown has an option whose ID matches the tool ID (or the `tools.config.tool` function correctly maps to it)
- [ ] Every **required** tool param (except `accessToken`) has a corresponding subBlock input that is:
  - Shown when that operation is selected (correct `condition`)
  - Marked as `required: true` (or conditionally required)
- [ ] Every **optional** tool param has a corresponding subBlock input (or is intentionally omitted if truly never needed)
- [ ] SubBlock `id` values are unique across the entire block — no duplicates even across different conditions
- [ ] The `tools.config.tool` function returns the correct tool ID for every possible operation value
- [ ] The `tools.config.params` function correctly maps subBlock IDs to tool param names when they differ

### SubBlocks
- [ ] Operation dropdown lists ALL tool operations available in `tools.access`
- [ ] Dropdown option labels are human-readable and descriptive
- [ ] Conditions use correct syntax:
  - Single value: `{ field: 'operation', value: 'x_create_tweet' }`
  - Multiple values (OR): `{ field: 'operation', value: ['x_create_tweet', 'x_delete_tweet'] }`
  - Negation: `{ field: 'operation', value: 'delete', not: true }`
  - Compound: `{ field: 'op', value: 'send', and: { field: 'type', value: 'dm' } }`
- [ ] Condition arrays include ALL operations that use that field — none missing
- [ ] `dependsOn` is set for fields that need other values (selectors depending on credential, cascading dropdowns)
- [ ] SubBlock types match tool param types:
  - Enum/fixed options → `dropdown`
  - Free text → `short-input`
  - Long text/content → `long-input`
  - True/false → `dropdown` with Yes/No options (not `switch` unless purely UI toggle)
  - Credentials → `oauth-input` with correct `serviceId`
- [ ] Dropdown `value: () => 'default'` is set for dropdowns with a sensible default

### Advanced Mode
- [ ] Optional, rarely-used fields are set to `mode: 'advanced'`:
  - Pagination tokens / next tokens
  - Time range filters (start/end time)
  - Sort order / direction options
  - Max results / per page limits
  - Reply settings / threading options
  - Rarely used IDs (reply-to, quote-tweet, etc.)
  - Exclude filters
- [ ] **Required** fields are NEVER set to `mode: 'advanced'`
- [ ] Fields that users fill in most of the time are NOT set to `mode: 'advanced'`

### WandConfig
- [ ] Timestamp fields have `wandConfig` with `generationType: 'timestamp'`
- [ ] Comma-separated list fields have `wandConfig` with a descriptive prompt
- [ ] Complex filter/query fields have `wandConfig` with format examples in the prompt
- [ ] All `wandConfig` prompts end with "Return ONLY the [format] - no explanations, no extra text."
- [ ] `wandConfig.placeholder` describes what to type in natural language

### Tools Config
- [ ] `tools.access` lists **every** tool ID the block can use — none missing
- [ ] `tools.config.tool` returns the correct tool ID for each operation
- [ ] Type coercions are in `tools.config.params` (runs at execution time), NOT in `tools.config.tool` (runs at serialization time before variable resolution)
- [ ] `tools.config.params` handles:
  - `Number()` conversion for numeric params that come as strings from inputs
  - `Boolean` / string-to-boolean conversion for toggle params
  - Empty string → `undefined` conversion for optional dropdown values
  - Any subBlock ID → tool param name remapping
- [ ] No `Number()`, `JSON.parse()`, or other coercions in `tools.config.tool` — these would destroy dynamic references like `<Block.output>`

### Block Outputs
- [ ] Outputs cover the key fields returned by ALL tools (not just one operation)
- [ ] Output types are correct (`'string'`, `'number'`, `'boolean'`, `'json'`)
- [ ] `type: 'json'` outputs either:
  - Describe inner fields in the description string (GOOD): `'User profile (id, name, username, bio)'`
  - Use nested output definitions (BEST): `{ id: { type: 'string' }, name: { type: 'string' } }`
- [ ] No opaque `type: 'json'` with vague descriptions like `'Response data'`
- [ ] Outputs that only appear for certain operations use `condition` if supported, or document which operations return them

### Block Metadata
- [ ] `type` is snake_case (e.g., `'x'`, `'cloudflare'`)
- [ ] `name` is human-readable (e.g., `'X'`, `'Cloudflare'`)
- [ ] `description` is a concise one-liner
- [ ] `longDescription` provides detail for docs
- [ ] `docsLink` points to `'https://docs.sim.ai/tools/{service}'`
- [ ] `category` is `'tools'`
- [ ] `bgColor` uses the service's brand color hex
- [ ] `icon` references the correct icon component from `@/components/icons`
- [ ] `authMode` is set correctly (`AuthMode.OAuth` or `AuthMode.ApiKey`)
- [ ] Block is registered in `blocks/registry.ts` alphabetically

### Block Inputs
- [ ] `inputs` section lists all subBlock params that the block accepts
- [ ] Input types match the subBlock types
- [ ] When using `canonicalParamId`, inputs list the canonical ID (not the raw subBlock IDs)

## Step 5: Validate OAuth Scopes (if OAuth service)

Scopes are centralized — the single source of truth is `OAUTH_PROVIDERS` in `lib/oauth/oauth.ts`.

- [ ] Scopes defined in `lib/oauth/oauth.ts` under `OAUTH_PROVIDERS[provider].services[service].scopes`
- [ ] `auth.ts` uses `getCanonicalScopesForProvider(providerId)` — NOT a hardcoded array
- [ ] Block `requiredScopes` uses `getScopesForService(serviceId)` — NOT a hardcoded array
- [ ] No hardcoded scope arrays in `auth.ts` or block files (should all use utility functions)
- [ ] Each scope has a human-readable description in `SCOPE_DESCRIPTIONS` within `lib/oauth/utils.ts`
- [ ] No excess scopes that aren't needed by any tool

## Step 6: Validate Pagination Consistency

If any tools support pagination:
- [ ] Pagination param names match the API docs (e.g., `pagination_token` vs `next_token` vs `cursor`)
- [ ] Different API endpoints that use different pagination param names have separate subBlocks in the block
- [ ] Pagination response fields (`nextToken`, `cursor`, etc.) are included in tool outputs
- [ ] Pagination subBlocks are set to `mode: 'advanced'`

## Step 7: Validate Error Handling

- [ ] `transformResponse` checks for error conditions before accessing data
- [ ] Error responses include meaningful messages (not just generic "failed")
- [ ] HTTP error status codes are handled (check `response.ok` or status codes)

## Step 8: Report and Fix

### Report Format

Group findings by severity:

**Critical** (will cause runtime errors or incorrect behavior):
- Wrong endpoint URL or HTTP method
- Missing required params or wrong `required` flag
- Incorrect response field mapping (accessing wrong path in response)
- Missing error handling that would cause crashes
- Tool ID mismatch between tool file, registry, and block `tools.access`
- OAuth scopes missing in `auth.ts` that tools need
- `tools.config.tool` returning wrong tool ID for an operation
- Type coercions in `tools.config.tool` instead of `tools.config.params`

**Warning** (follows conventions incorrectly or has usability issues):
- Optional field not set to `mode: 'advanced'`
- Missing `wandConfig` on timestamp/complex fields
- Wrong `visibility` on params (e.g., `'hidden'` instead of `'user-or-llm'`)
- Missing `optional: true` on nullable outputs
- Opaque `type: 'json'` without property descriptions
- Missing `.trim()` on ID fields in request URLs
- Missing `?? null` on nullable response fields
- Block condition array missing an operation that uses that field
- Hardcoded scope arrays instead of using `getScopesForService()` / `getCanonicalScopesForProvider()`
- Missing scope description in `SCOPE_DESCRIPTIONS` within `lib/oauth/utils.ts`

**Suggestion** (minor improvements):
- Better description text
- Inconsistent naming across tools
- Missing `longDescription` or `docsLink`
- Pagination fields that could benefit from `wandConfig`

### Fix All Issues

After reporting, fix every **critical** and **warning** issue. Apply **suggestions** where they don't add unnecessary complexity.

### Validation Output

After fixing, confirm:
1. `bun run lint` passes with no fixes needed
2. TypeScript compiles clean (no type errors)
3. Re-read all modified files to verify fixes are correct
