---

# Add Connector Skill

You are an expert at adding knowledge base connectors to Sim. A connector syncs documents from an external source (Confluence, Google Drive, Notion, etc.) into a knowledge base.

## Your Task

When the user asks you to create a connector:
1. Use Context7 or WebFetch to read the service's API documentation
2. Determine the auth mode: **OAuth** (if Sim already has an OAuth provider for the service) or **API key** (if the service uses API key / Bearer token auth)
3. Create the connector directory: a client-safe `meta.ts` (declarative metadata) plus the runtime module that spreads it
4. Register it in BOTH the server registry and the client-safe meta registry

## Hard Rule: No Guessed Response Or Document Schemas

If the service docs do not clearly show the document list response, document fetch response, pagination shape, or metadata fields, you MUST tell the user instead of guessing.

- Do NOT invent document fields
- Do NOT guess pagination cursors or next-page fields
- Do NOT infer metadata/tag mappings from unrelated endpoints
- Do NOT fabricate `ExternalDocument` content structure from partial docs

If the source schema is unknown, do one of these instead:
1. Ask the user for sample API responses
2. Ask the user for test credentials so you can verify live payloads
3. Implement only the documented parts of the connector
4. Leave the connector incomplete and explicitly say which fields remain unknown

## Directory Structure

Each connector is split into a client-safe metadata file and a server-only runtime file. This mirrors the `XBlockMeta` / `BLOCK_META_REGISTRY` split in `apps/sim/blocks` — client components (the knowledge UI) only need the metadata (icon, name, auth, config fields), so the runtime functions (which pull server-only helpers like `input-validation.server` → `undici` → `node:net`) must stay out of the client bundle.

Create files in `apps/sim/connectors/{service}/`:
```
connectors/{service}/
├── index.ts          # Barrel export (re-exports the runtime connector)
├── meta.ts           # ConnectorMeta — client-safe declarative metadata
└── {service}.ts      # ConnectorConfig — spreads the meta + adds runtime functions
```

- `meta.ts` exports `{service}ConnectorMeta: ConnectorMeta`. It imports ONLY the icon from `@/components/icons`, `import type { ConnectorMeta } from '@/connectors/types'`, and any pure-data constants. It must NEVER import server/runtime code.
- `{service}.ts` exports `{service}Connector: ConnectorConfig`. It imports the meta via `import { {service}ConnectorMeta } from '@/connectors/{service}/meta'`, spreads it as the first property, and holds the runtime functions (which may import server-only helpers like `@/lib/knowledge/documents/utils`).

## Authentication

Connectors use a discriminated union for auth config (`ConnectorAuthConfig` in `connectors/types.ts`):

```typescript
type ConnectorAuthConfig =
  | { mode: 'oauth'; provider: OAuthService; requiredScopes?: string[] }
  | { mode: 'apiKey'; label?: string; placeholder?: string }
```

### OAuth mode
For services with existing OAuth providers in `apps/sim/lib/oauth/types.ts`. The `provider` must match an `OAuthService`. The modal shows a credential picker and handles token refresh automatically.

### API key mode
For services that use API key / Bearer token auth. The modal shows a password input with the configured `label` and `placeholder`. The API key is encrypted at rest using AES-256-GCM and stored in a dedicated `encryptedApiKey` column on the connector record. The sync engine decrypts it automatically — connectors receive the raw access token in `listDocuments`, `getDocument`, and `validateConfig`.

## Connector Structure (meta.ts + runtime)

The declarative metadata lives in `meta.ts` (`ConnectorMeta`). The runtime functions live in `{service}.ts` (`ConnectorConfig`), which spreads the meta as its first property.

### `meta.ts` — client-safe metadata

```typescript
import { {Service}Icon } from '@/components/icons'
import type { ConnectorMeta } from '@/connectors/types'

export const {service}ConnectorMeta: ConnectorMeta = {
  id: '{service}',
  name: '{Service}',
  description: 'Sync documents from {Service} into your knowledge base',
  version: '1.0.0',
  icon: {Service}Icon,

  auth: {
    mode: 'oauth',
    provider: '{service}',          // Must match OAuthService in lib/oauth/types.ts
    requiredScopes: ['read:...'],
  },

  configFields: [
    // Rendered dynamically by the add-connector modal UI
    // Supports 'short-input' and 'dropdown' types
  ],

  // Optional: tag definitions are metadata too — declare them here
  // tagDefinitions: [ ... ],
}
```

Keep `meta.ts` free of any server/runtime import. Only the icon, the `ConnectorMeta` type, and pure-data constants belong here.

### `{service}.ts` — runtime (OAuth example)

```typescript
import { createLogger } from '@sim/logger'
import { fetchWithRetry } from '@/lib/knowledge/documents/utils'
import { {service}ConnectorMeta } from '@/connectors/{service}/meta'
import type { ConnectorConfig, ExternalDocument, ExternalDocumentList } from '@/connectors/types'

const logger = createLogger('{Service}Connector')

export const {service}Connector: ConnectorConfig = {
  ...{service}ConnectorMeta,

  listDocuments: async (accessToken, sourceConfig, cursor) => {
    // Return metadata stubs with contentDeferred: true (if per-doc content fetch needed)
    // Or full documents with content (if list API returns content inline)
    // Return { documents: ExternalDocument[], nextCursor?, hasMore }
  },

  getDocument: async (accessToken, sourceConfig, externalId) => {
    // Fetch full content for a single document
    // Return ExternalDocument with contentDeferred: false, or null
  },

  validateConfig: async (accessToken, sourceConfig) => {
    // Return { valid: true } or { valid: false, error: 'message' }
  },

  // Optional: map source metadata to semantic tag keys (translated to slots by sync engine)
  mapTags: (metadata) => {
    // Return Record<string, unknown> with keys matching tagDefinitions[].id
  },
}
```

Only map fields in `listDocuments`, `getDocument`, `validateConfig`, and `mapTags` when the source payload shape is documented or live-verified. If not, tell the user and stop rather than guessing.

### API key connector example

The split is identical — `auth` lives in `meta.ts`, runtime functions in `{service}.ts`.

```typescript
// meta.ts
export const {service}ConnectorMeta: ConnectorMeta = {
  id: '{service}',
  name: '{Service}',
  description: 'Sync documents from {Service} into your knowledge base',
  version: '1.0.0',
  icon: {Service}Icon,

  auth: {
    mode: 'apiKey',
    label: 'API Key',                       // Shown above the input field
    placeholder: 'Enter your {Service} API key',  // Input placeholder
  },

  configFields: [ /* ... */ ],
}

// {service}.ts
export const {service}Connector: ConnectorConfig = {
  ...{service}ConnectorMeta,
  listDocuments: async (accessToken, sourceConfig, cursor) => { /* ... */ },
  getDocument: async (accessToken, sourceConfig, externalId) => { /* ... */ },
  validateConfig: async (accessToken, sourceConfig) => { /* ... */ },
}
```

## ConfigField Types

The add-connector modal renders these automatically — no custom UI needed.

Three field types are supported: `short-input`, `dropdown`, and `selector`.

```typescript
// Text input
{
  id: 'domain',
  title: 'Domain',
  type: 'short-input',
  placeholder: 'yoursite.example.com',
  required: true,
}

// Dropdown (static options)
{
  id: 'contentType',
  title: 'Content Type',
  type: 'dropdown',
  required: false,
  options: [
    { label: 'Pages only', id: 'page' },
    { label: 'Blog posts only', id: 'blogpost' },
    { label: 'All content', id: 'all' },
  ],
}
```

## Dynamic Selectors (Canonical Pairs)

Use `type: 'selector'` to fetch options dynamically from the existing selector registry (`hooks/selectors/registry.ts`). Selectors are always paired with a manual fallback input using the **canonical pair** pattern — a `selector` field (basic mode) and a `short-input` field (advanced mode) linked by `canonicalParamId`.

The user sees a toggle button (ArrowLeftRight) to switch between the selector dropdown and manual text input. On submit, the modal resolves each canonical pair to the active mode's value, keyed by `canonicalParamId`.

### Rules

1. **Every selector field MUST have a canonical pair** — a corresponding `short-input` (or `dropdown`) field with the same `canonicalParamId` and `mode: 'advanced'`.
2. **`required` must be set identically on both fields** in a pair. If the selector is required, the manual input must also be required.
3. **`canonicalParamId` must match the key the connector expects in `sourceConfig`** (e.g. `baseId`, `channel`, `teamId`). The advanced field's `id` should typically match `canonicalParamId`.
4. **`dependsOn` references the selector field's `id`**, not the `canonicalParamId`. The modal propagates dependency clearing across canonical siblings automatically — changing either field in a parent pair clears dependent children.

### Selector canonical pair example (Airtable base → table cascade)

```typescript
configFields: [
  // Base: selector (basic) + manual (advanced)
  {
    id: 'baseSelector',
    title: 'Base',
    type: 'selector',
    selectorKey: 'airtable.bases',     // Must exist in hooks/selectors/registry.ts
    canonicalParamId: 'baseId',
    mode: 'basic',
    placeholder: 'Select a base',
    required: true,
  },
  {
    id: 'baseId',
    title: 'Base ID',
    type: 'short-input',
    canonicalParamId: 'baseId',
    mode: 'advanced',
    placeholder: 'e.g. appXXXXXXXXXXXXXX',
    required: true,
  },
  // Table: selector depends on base (basic) + manual (advanced)
  {
    id: 'tableSelector',
    title: 'Table',
    type: 'selector',
    selectorKey: 'airtable.tables',
    canonicalParamId: 'tableIdOrName',
    mode: 'basic',
    dependsOn: ['baseSelector'],       // References the selector field ID
    placeholder: 'Select a table',
    required: true,
  },
  {
    id: 'tableIdOrName',
    title: 'Table Name or ID',
    type: 'short-input',
    canonicalParamId: 'tableIdOrName',
    mode: 'advanced',
    placeholder: 'e.g. Tasks',
    required: true,
  },
  // Non-selector fields stay as-is
  { id: 'maxRecords', title: 'Max Records', type: 'short-input', ... },
]
```

### Selector with domain dependency (Jira/Confluence pattern)

When a selector depends on a plain `short-input` field (no canonical pair), `dependsOn` references that field's `id` directly. The `domain` field's value maps to `SelectorContext.domain` automatically via `SELECTOR_CONTEXT_FIELDS`.

```typescript
configFields: [
  {
    id: 'domain',
    title: 'Jira Domain',
    type: 'short-input',
    placeholder: 'yoursite.atlassian.net',
    required: true,
  },
  {
    id: 'projectSelector',
    title: 'Project',
    type: 'selector',
    selectorKey: 'jira.projects',
    canonicalParamId: 'projectKey',
    mode: 'basic',
    dependsOn: ['domain'],
    placeholder: 'Select a project',
    required: true,
  },
  {
    id: 'projectKey',
    title: 'Project Key',
    type: 'short-input',
    canonicalParamId: 'projectKey',
    mode: 'advanced',
    placeholder: 'e.g. ENG, PROJ',
    required: true,
  },
]
```

### How `dependsOn` maps to `SelectorContext`

The connector selector field builds a `SelectorContext` from dependency values. For the mapping to work, each dependency's `canonicalParamId` (or field `id` for non-canonical fields) must exist in `SELECTOR_CONTEXT_FIELDS` (`lib/workflows/subblocks/context.ts`):

```
oauthCredential, domain, teamId, projectId, knowledgeBaseId, planId,
siteId, collectionId, spreadsheetId, fileId, baseId, datasetId, serviceDeskId
```

### Available selector keys

Check `hooks/selectors/types.ts` for the full `SelectorKey` union. Common ones for connectors:

| SelectorKey | Context Deps | Returns |
|-------------|-------------|---------|
| `airtable.bases` | credential | Base ID + name |
| `airtable.tables` | credential, `baseId` | Table ID + name |
| `slack.channels` | credential | Channel ID + name |
| `gmail.labels` | credential | Label ID + name |
| `google.calendar` | credential | Calendar ID + name |
| `linear.teams` | credential | Team ID + name |
| `linear.projects` | credential, `teamId` | Project ID + name |
| `jira.projects` | credential, `domain` | Project key + name |
| `confluence.spaces` | credential, `domain` | Space key + name |
| `notion.databases` | credential | Database ID + name |
| `asana.workspaces` | credential | Workspace GID + name |
| `microsoft.teams` | credential | Team ID + name |
| `microsoft.channels` | credential, `teamId` | Channel ID + name |
| `webflow.sites` | credential | Site ID + name |
| `outlook.folders` | credential | Folder ID + name |

## ExternalDocument Shape

Every document returned from `listDocuments`/`getDocument` must include:

```typescript
{
  externalId: string          // Source-specific unique ID
  title: string               // Document title
  content: string             // Extracted plain text (or '' if contentDeferred)
  contentDeferred?: boolean   // true = content will be fetched via getDocument
  mimeType: 'text/plain'     // Always text/plain (content is extracted)
  contentHash: string         // Metadata-based hash for change detection
  sourceUrl?: string          // Link back to original (stored on document record)
  metadata?: Record<string, unknown>  // Source-specific data (fed to mapTags)
}
```

## Content Deferral (Required for file/content-download connectors)

**All connectors that require per-document API calls to fetch content MUST use `contentDeferred: true`.** This is the standard pattern — `listDocuments` returns lightweight metadata stubs, and content is fetched lazily by the sync engine via `getDocument` only for new/changed documents.

This pattern is critical for reliability: the sync engine processes documents in batches and enqueues each batch for processing immediately. If a sync times out, all previously-batched documents are already queued. Without deferral, content downloads during listing can exhaust the sync task's time budget before any documents are saved.

### When to use `contentDeferred: true`

- The service's list API does NOT return document content (only metadata)
- Content requires a separate download/export API call per document
- Examples: Google Drive, OneDrive, SharePoint, Dropbox, Notion, Confluence, Gmail, Obsidian, Evernote, GitHub

### When NOT to use `contentDeferred`

- The list API already returns the full content inline (e.g., Slack messages, Reddit posts, HubSpot notes)
- No per-document API call is needed to get content

### Content Hash Strategy

Use a **metadata-based** `contentHash` — never a content-based hash. The hash must be derivable from the list response metadata alone, so the sync engine can detect changes without downloading content.

Good metadata hash sources:
- `modifiedTime` / `lastModifiedDateTime` — changes when file is edited
- Git blob SHA — unique per content version
- API-provided content hash (e.g., Dropbox `content_hash`)
- Version number (e.g., Confluence page version)

Format: `{service}:{id}:{changeIndicator}`

```typescript
// Google Drive: modifiedTime changes on edit
contentHash: `gdrive:${file.id}:${file.modifiedTime ?? ''}`

// GitHub: blob SHA is a content-addressable hash
contentHash: `gitsha:${item.sha}`

// Dropbox: API provides content_hash
contentHash: `dropbox:${entry.id}:${entry.content_hash ?? entry.server_modified}`

// Confluence: version number increments on edit
contentHash: `confluence:${page.id}:${page.version.number}`
```

**Critical invariant:** The `contentHash` MUST be identical whether produced by `listDocuments` (stub) or `getDocument` (full doc). Both should use the same stub function to guarantee this.

### Implementation Pattern

```typescript
// 1. Create a stub function (sync, no API calls)
function fileToStub(file: ServiceFile): ExternalDocument {
  return {
    externalId: file.id,
    title: file.name || 'Untitled',
    content: '',
    contentDeferred: true,
    mimeType: 'text/plain',
    sourceUrl: `https://service.com/file/${file.id}`,
    contentHash: `service:${file.id}:${file.modifiedTime ?? ''}`,
    metadata: { /* fields needed by mapTags */ },
  }
}

// 2. listDocuments returns stubs (fast, metadata only)
listDocuments: async (accessToken, sourceConfig, cursor) => {
  const response = await fetchWithRetry(listUrl, { ... })
  const files = (await response.json()).files
  const documents = files.map(fileToStub)
  return { documents, nextCursor, hasMore }
}

// 3. getDocument fetches content and returns full doc with SAME contentHash
getDocument: async (accessToken, sourceConfig, externalId) => {
  const metadata = await fetchWithRetry(metadataUrl, { ... })
  const file = await metadata.json()
  if (file.trashed) return null

  try {
    const content = await fetchContent(accessToken, file)
    if (!content.trim()) return null
    const stub = fileToStub(file)
    return { ...stub, content, contentDeferred: false }
  } catch (error) {
    logger.warn(`Failed to fetch content for: ${file.name}`, { error })
    return null
  }
}
```

### Reference Implementations

- **Google Drive**: `connectors/google-drive/google-drive.ts` — file download/export with `modifiedTime` hash
- **GitHub**: `connectors/github/github.ts` — git blob SHA hash
- **Notion**: `connectors/notion/notion.ts` — blocks API with `last_edited_time` hash
- **Confluence**: `connectors/confluence/confluence.ts` — version number hash

## tagDefinitions — Declared Tag Definitions

Declare which tags the connector populates using semantic IDs. Shown in the add-connector modal as opt-out checkboxes.
On connector creation, slots are **dynamically assigned** via `getNextAvailableSlot` — connectors never hardcode slot names.

```typescript
tagDefinitions: [
  { id: 'labels', displayName: 'Labels', fieldType: 'text' },
  { id: 'version', displayName: 'Version', fieldType: 'number' },
  { id: 'lastModified', displayName: 'Last Modified', fieldType: 'date' },
],
```

Each entry has:
- `id`: Semantic key matching a key returned by `mapTags` (e.g. `'labels'`, `'version'`)
- `displayName`: Human-readable name shown in the UI (e.g. "Labels", "Last Modified")
- `fieldType`: `'text'` | `'number'` | `'date'` | `'boolean'` — determines which slot pool to draw from

Users can opt out of specific tags in the modal. Disabled IDs are stored in `sourceConfig.disabledTagIds`.
The assigned mapping (`semantic id → slot`) is stored in `sourceConfig.tagSlotMapping`.

## mapTags — Metadata to Semantic Keys

Maps source metadata to semantic tag keys. Required if `tagDefinitions` is set.
The sync engine calls this automatically and translates semantic keys to actual DB slots
using the `tagSlotMapping` stored on the connector.

Return keys must match the `id` values declared in `tagDefinitions`.

```typescript
mapTags: (metadata: Record<string, unknown>): Record<string, unknown> => {
  const result: Record<string, unknown> = {}

  // Validate arrays before casting — metadata may be malformed
  const labels = Array.isArray(metadata.labels) ? (metadata.labels as string[]) : []
  if (labels.length > 0) result.labels = labels.join(', ')

  // Validate numbers — guard against NaN
  if (metadata.version != null) {
    const num = Number(metadata.version)
    if (!Number.isNaN(num)) result.version = num
  }

  // Validate dates — guard against Invalid Date
  if (typeof metadata.lastModified === 'string') {
    const date = new Date(metadata.lastModified)
    if (!Number.isNaN(date.getTime())) result.lastModified = date
  }

  return result
}
```

## External API Calls — Use `fetchWithRetry`

All external API calls must use `fetchWithRetry` from `@/lib/knowledge/documents/utils` instead of raw `fetch()`. This provides exponential backoff with retries on 429/502/503/504 errors. It returns a standard `Response` — all `.ok`, `.json()`, `.text()` checks work unchanged.

For `validateConfig` (user-facing, called on save), pass `VALIDATE_RETRY_OPTIONS` to cap wait time at ~7s. Background operations (`listDocuments`, `getDocument`) use the built-in defaults (5 retries, ~31s max).

```typescript
import { VALIDATE_RETRY_OPTIONS, fetchWithRetry } from '@/lib/knowledge/documents/utils'

// Background sync — use defaults
const response = await fetchWithRetry(url, {
  method: 'GET',
  headers: { Authorization: `Bearer ${accessToken}` },
})

// validateConfig — tighter retry budget
const response = await fetchWithRetry(url, { ... }, VALIDATE_RETRY_OPTIONS)
```

## sourceUrl

If `ExternalDocument.sourceUrl` is set, the sync engine stores it on the document record. Always construct the full URL (not a relative path).

## Sync Engine Behavior (Do Not Modify)

The sync engine (`lib/knowledge/connectors/sync-engine.ts`) is connector-agnostic. It:
1. Calls `listDocuments` with pagination until `hasMore` is false
2. Compares `contentHash` to detect new/changed/unchanged documents
3. Stores `sourceUrl` and calls `mapTags` on insert/update automatically
4. Handles soft-delete of removed documents
5. Resolves access tokens automatically — OAuth tokens are refreshed, API keys are decrypted from the `encryptedApiKey` column

You never need to modify the sync engine when adding a connector.

## Icon

The `icon` field on `ConnectorConfig` is used throughout the UI — in the connector list, the add-connector modal, and as the document icon in the knowledge base table (replacing the generic file type icon for connector-sourced documents). The icon is read from `CONNECTOR_REGISTRY[connectorType].icon` at runtime — no separate icon map to maintain.

If the service already has an icon in `apps/sim/components/icons.tsx` (from a tool integration), reuse it. Otherwise, ask the user to provide the SVG.

## Registering

Register in BOTH registries, keeping the same alphabetical-by-id ordering in each.

1. **Server registry** — `apps/sim/connectors/registry.server.ts` (server-only full registry; holds full connectors with runtime functions, imported by the sync engine and knowledge API routes):

```typescript
import { {service}Connector } from '@/connectors/{service}'

export const CONNECTOR_REGISTRY: ConnectorRegistry = {
  // ... existing connectors ...
  {service}: {service}Connector,
}
```

2. **Client-safe meta registry** — `apps/sim/connectors/registry.ts` (imports each connector's `meta.ts` only, so client components can use it without pulling server-only code; the metadata counterpart to `BLOCK_META_REGISTRY`):

```typescript
import { {service}ConnectorMeta } from '@/connectors/{service}/meta'

export const CONNECTOR_META_REGISTRY: ConnectorMetaRegistry = {
  // ... existing connector metas ...
  {service}: {service}ConnectorMeta,
}
```

`registry.ts` exports `CONNECTOR_META_REGISTRY: ConnectorMetaRegistry` plus the helpers `getConnectorMeta(id)` and `getAllConnectorMeta()`, importing each `@/connectors/{service}/meta` directly — never the runtime module. `registry.server.ts` exports `CONNECTOR_REGISTRY: ConnectorRegistry`.

## Reference Implementations

- **OAuth + contentDeferred**: `apps/sim/connectors/google-drive/google-drive.ts` — file download with metadata-based hash, `orderBy` for deterministic pagination
- **OAuth + contentDeferred (blocks API)**: `apps/sim/connectors/notion/notion.ts` — complex block content extraction deferred to `getDocument`
- **OAuth + contentDeferred (git)**: `apps/sim/connectors/github/github.ts` — blob SHA hash, tree listing
- **OAuth + inline content**: `apps/sim/connectors/confluence/confluence.ts` — multiple config field types, `mapTags`, label fetching
- **API key**: `apps/sim/connectors/fireflies/fireflies.ts` — GraphQL API with Bearer token auth
