Add Block Skill

You are an expert at creating block configurations for Sim. You understand the serializer, subBlock types, conditions, dependsOn, modes, and all UI patterns.

Your Task

When the user asks you to create a block:

Create the block file in apps/sim/blocks/blocks/{service}.ts
Configure all subBlocks with proper types, conditions, and dependencies
Wire up tools correctly

No guessed tool outputs

Block outputs mirror tool outputs. When a tool's response schema is neither documented nor live-verified, don't infer field names or JSON shapes — ask the user for sample responses or test credentials, limit the block to operations whose outputs are documented, or leave the uncertain outputs out and say exactly what remains unknown.

Block Configuration Structure

import { {ServiceName}Icon } from '@/components/icons'
import type { BlockConfig } from '@/blocks/types'
import { AuthMode, IntegrationType } from '@/blocks/types'
import { getScopesForService } from '@/lib/oauth/utils'

export const {ServiceName}Block: BlockConfig = {
  type: '{service}',                    // snake_case identifier
  name: '{Service Name}',               // Human readable
  description: 'Brief description',     // One sentence
  longDescription: 'Detailed description for docs',
  docsLink: 'https://docs.sim.ai/integrations/{service}',
  category: 'tools',                    // 'tools' | 'blocks' | 'triggers'
  integrationType: IntegrationType.X,   // Primary category (see IntegrationType enum)
  tags: ['oauth', 'api'],              // Cross-cutting tags (see IntegrationTag type)
  bgColor: '#HEXCOLOR',                 // Brand color

    sentences: { byOperation: { /* one per operation dropdown option id */ } },
  },

  subBlocks: [
    // Define all UI fields here
  ],

  tools: {
    access: ['tool_id_1', 'tool_id_2'], // Array of tool IDs this block can use
    config: {
      tool: (params) => `{service}_${params.operation}`,  // Tool selector function
      params: (params) => ({
        // Transform subBlock values to tool params
      }),
    },
  },

  inputs: {
    // Optional: define expected inputs from other blocks
  },

  outputs: {
    // Define outputs available to downstream blocks
  },
}

SubBlock Types Reference

Critical: Every subblock id must be unique within the block. Duplicate IDs cause conflicts even with different conditions.

Text Inputs

// Single-line input
{ id: 'field', title: 'Label', type: 'short-input', placeholder: '...' }

// Multi-line input
{ id: 'field', title: 'Label', type: 'long-input', placeholder: '...', rows: 6 }

// Password input
{ id: 'apiKey', title: 'API Key', type: 'short-input', password: true }

Selection Inputs

// Dropdown (static options)
{
  id: 'operation',
  title: 'Operation',
  type: 'dropdown',
  options: [
    { label: 'Create', id: 'create' },
    { label: 'Update', id: 'update' },
  ],
  value: () => 'create',  // Default value function
}

// Combobox (searchable dropdown)
{
  id: 'field',
  title: 'Label',
  type: 'combobox',
  options: [...],
  searchable: true,
}

Code/JSON Inputs

{
  id: 'code',
  title: 'Code',
  type: 'code',
  language: 'javascript',  // 'javascript' | 'json' | 'python'
  placeholder: '// Enter code...',
}

OAuth/Credentials

{
  id: 'credential',
  title: 'Account',
  type: 'oauth-input',
  serviceId: '{service}',  // Must match OAuth provider service key
  requiredScopes: getScopesForService('{service}'),  // Import from @/lib/oauth/utils
  placeholder: 'Select account',
  required: true,
}

Scopes: Always use getScopesForService(serviceId) from @/lib/oauth/utils for requiredScopes. Never hardcode scope arrays — the single source of truth is OAUTH_PROVIDERS in lib/oauth/oauth.ts.

Scope descriptions: When adding a new OAuth provider, also add human-readable descriptions for all scopes in SCOPE_DESCRIPTIONS within lib/oauth/utils.ts.

Service accounts (shared, app-level credentials): A plain oauth-input already lets users select an existing service account — those credentials fold into the picker automatically (a Google service account created for any Google service appears in every Google block's picker). You only set credentialKind when you want to change the connect action:

{
  id: 'credential',
  title: 'Account',
  type: 'oauth-input',
  serviceId: '{service}',
  requiredScopes: getScopesForService('{service}'),
  credentialKind: 'any',   // omit | 'service-account' | 'any'
}

omit (default): lists OAuth accounts + any existing service accounts; the only connect action is "Connect account" (OAuth). Use this for the common "let users pick a service account someone set up elsewhere, but don't offer inline setup" case — no config needed.
'service-account': service-account credentials only, plus an inline setup action that opens the provider's connect modal. Use when a block accepts only an app credential.
'any': merged picker — OAuth accounts and service accounts in one grouped dropdown, with a connect action for each. Use when a block supports both (e.g. Slack: a personal account or a custom bot).

Optional companions: credentialLabels (override the picker's section/connect-row copy) and allowServiceAccounts: true (trigger-mode only — list service accounts, which triggers otherwise exclude; set only when the trigger's polling path can resolve a service-account token). The connect modal, provider families (Google JSON key, Atlassian token, token-paste, client-credential, Slack bot), and the preview gate are all resolved from serviceAccountProviderId — you don't wire them per block.

OAuth deployment availability (required for integration blocks)

A visible tools-category block with OAuth is deployment-gated. Its oauth-input.serviceId is projected into packages/deployment-config/src/integrations.json, then resolved through resolveOAuthClientCapabilityId() in packages/deployment-config/src/env-capabilities.ts.

When adding or changing an OAuth integration block:

Keep exactly one distinct OAuth serviceId across the block's oauth-input subBlocks.
Confirm that service ID resolves to an entry in OAUTH_CLIENT_CAPABILITIES. Google and Microsoft service IDs intentionally share their provider-level capability; do not add duplicate entries for those aliases.
For a new capability, add its required client fields to OAUTH_CLIENT_CAPABILITIES and ensure every referenced field exists in the env schema in apps/sim/lib/core/config/env.ts. Then add the matching text or secret input modes to OAUTH_CLIENT_SETUP_FIELDS in packages/sim-setup/src/capability-config.ts. The CLI catalog is exhaustively typed and checked against the runtime field list; do not infer secrecy from the field name.
If the canonical OAuth service declares serviceAccountProviderId, run bun run deployment-config:generate; this regenerates the provider-ID facts in packages/deployment-config/src/service-account-providers.generated.ts. Never hand-edit that generated map. Add deploymentRequirement policy in packages/deployment-config/src/service-account-metadata.ts only when the service-account path is preview-gated or depends on the OAuth client fields; otherwise omit it.

Missing capability metadata is a runtime configuration error, not a reason to make the integration silently available.

Selectors (with dynamic options)

// Channel selector (Slack, Discord, etc.)
{
  id: 'channel',
  title: 'Channel',
  type: 'channel-selector',
  selectorKey: '{service}.channels',
  serviceId: '{service}',
  placeholder: 'Select channel',
  dependsOn: ['credential'],
}

// Project selector (Jira, etc.)
{
  id: 'project',
  title: 'Project',
  type: 'project-selector',
  selectorKey: '{service}.projects',
  serviceId: '{service}',
  dependsOn: ['credential'],
}

// File selector (Google Drive, etc.)
{
  id: 'file',
  title: 'File',
  type: 'file-selector',
  selectorKey: '{service}.files',
  serviceId: '{service}',
  mimeType: 'application/pdf',
  dependsOn: ['credential'],
}

// User selector
{
  id: 'user',
  title: 'User',
  type: 'user-selector',
  selectorKey: '{service}.users',
  serviceId: '{service}',
  dependsOn: ['credential'],
}

Other Types

// Switch/toggle
{ id: 'enabled', type: 'switch' }

// Slider
{ id: 'temperature', title: 'Temperature', type: 'slider', min: 0, max: 2, step: 0.1 }

// Table (key-value pairs)
{ id: 'headers', title: 'Headers', type: 'table', columns: ['Key', 'Value'] }

// File upload
{
  id: 'files',
  title: 'Attachments',
  type: 'file-upload',
  multiple: true,
  acceptedTypes: 'image/*,application/pdf',
}

File Input Handling

When your block accepts file uploads, use the basic/advanced mode pattern with normalizeFileInput.

Basic/Advanced File Pattern

// Basic mode: Visual file upload
{
  id: 'uploadFile',
  title: 'File',
  type: 'file-upload',
  canonicalParamId: 'file',  // Both map to 'file' param
  placeholder: 'Upload file',
  mode: 'basic',
  multiple: false,
  required: true,
  condition: { field: 'operation', value: 'upload' },
},
// Advanced mode: Reference from other blocks
{
  id: 'fileRef',
  title: 'File',
  type: 'short-input',
  canonicalParamId: 'file',  // Both map to 'file' param
  placeholder: 'Reference file (e.g., {{file_block.output}})',
  mode: 'advanced',
  required: true,
  condition: { field: 'operation', value: 'upload' },
},

Keep the pair to one logical thing. Basic is the file upload, advanced is only a reference to a file from a previous block. Gmail attachments are the reference implementation (apps/sim/blocks/blocks/gmail.ts — attachmentFiles / attachments).

Do not overload the advanced side with alternate identifiers (a remote URL, a provider asset ID, a path). A subblock whose meaning changes based on what the string looks like is impossible to reason about, forces the params function to sniff the value, and makes the field's type meaningless. Give each alternative its own subblock outside the pair:

// ✓ Good — the pair is "a file"; other sources are their own fields
{ id: 'mediaFile',    type: 'file-upload', canonicalParamId: 'media', mode: 'basic' },
{ id: 'mediaFileRef', type: 'short-input', canonicalParamId: 'media', mode: 'advanced' },
{ id: 'mediaId',      type: 'short-input', mode: 'advanced' },  // separate concept
{ id: 'mediaLink',    type: 'short-input', mode: 'advanced' },  // separate concept

// ✗ Bad — one field meaning three things, resolved by guessing
{ id: 'mediaRef', type: 'short-input', canonicalParamId: 'media', mode: 'advanced',
  placeholder: 'File reference, media ID, or public URL' },

When several fields are mutually exclusive alternatives, mark them all required: false and enforce "exactly one" at execution — a conditionally-required canonical pair rejects the workflow before the other paths ever get a chance to supply the value.

Constraints (block-wide):

canonicalParamId must not equal any subblock id in the block.
One canonical id links exactly one basic/advanced pair for one logical parameter. Groups are keyed by canonical id across every subblock and hold one basicId, so two operations that each need a pair need tw

# Add Block Skill

You are an expert at creating block configurations for Sim. You understand the serializer, subBlock types, conditions, dependsOn, modes, and all UI patterns.

## Your Task

When the user asks you to create a block:
1. Create the block file in `apps/sim/blocks/blocks/{service}.ts`
2. Configure all subBlocks with proper types, conditions, and dependencies
3. Wire up tools correctly

## No guessed tool outputs

Block outputs mirror tool outputs. When a tool's response schema is neither documented nor live-verified, don't infer field names or JSON shapes — ask the user for sample responses or test credentials, limit the block to operations whose outputs are documented, or leave the uncertain outputs out and say exactly what remains unknown.

## Block Configuration Structure

```typescript
import { {ServiceName}Icon } from '@/components/icons'
import type { BlockConfig } from '@/blocks/types'
import { AuthMode, IntegrationType } from '@/blocks/types'
import { getScopesForService } from '@/lib/oauth/utils'

export const {ServiceName}Block: BlockConfig = {
  type: '{service}',                    // snake_case identifier
  name: '{Service Name}',               // Human readable
  description: 'Brief description',     // One sentence
  longDescription: 'Detailed description for docs',
  docsLink: 'https://docs.sim.ai/integrations/{service}',
  category: 'tools',                    // 'tools' | 'blocks' | 'triggers'
  integrationType: IntegrationType.X,   // Primary category (see IntegrationType enum)
  tags: ['oauth', 'api'],              // Cross-cutting tags (see IntegrationTag type)
  bgColor: '#HEXCOLOR',                 // Brand color
  icon: {ServiceName}Icon,

  // Auth mode
  authMode: AuthMode.OAuth,             // or AuthMode.ApiKey

  // Card summary sentences — see "Canvas Sentences" below
  canvasPresentation: {
    defaultTitle: '{Default Operation}',
    sentences: { byOperation: { /* one per operation dropdown option id */ } },
  },

  subBlocks: [
    // Define all UI fields here
  ],

  tools: {
    access: ['tool_id_1', 'tool_id_2'], // Array of tool IDs this block can use
    config: {
      tool: (params) => `{service}_${params.operation}`,  // Tool selector function
      params: (params) => ({
        // Transform subBlock values to tool params
      }),
    },
  },

  inputs: {
    // Optional: define expected inputs from other blocks
  },

  outputs: {
    // Define outputs available to downstream blocks
  },
}
```

## SubBlock Types Reference

**Critical:** Every subblock `id` must be unique within the block. Duplicate IDs cause conflicts even with different conditions.

### Text Inputs
```typescript
// Single-line input
{ id: 'field', title: 'Label', type: 'short-input', placeholder: '...' }

// Multi-line input
{ id: 'field', title: 'Label', type: 'long-input', placeholder: '...', rows: 6 }

// Password input
{ id: 'apiKey', title: 'API Key', type: 'short-input', password: true }
```

### Selection Inputs
```typescript
// Dropdown (static options)
{
  id: 'operation',
  title: 'Operation',
  type: 'dropdown',
  options: [
    { label: 'Create', id: 'create' },
    { label: 'Update', id: 'update' },
  ],
  value: () => 'create',  // Default value function
}

// Combobox (searchable dropdown)
{
  id: 'field',
  title: 'Label',
  type: 'combobox',
  options: [...],
  searchable: true,
}
```

### Code/JSON Inputs
```typescript
{
  id: 'code',
  title: 'Code',
  type: 'code',
  language: 'javascript',  // 'javascript' | 'json' | 'python'
  placeholder: '// Enter code...',
}
```

### OAuth/Credentials
```typescript
{
  id: 'credential',
  title: 'Account',
  type: 'oauth-input',
  serviceId: '{service}',  // Must match OAuth provider service key
  requiredScopes: getScopesForService('{service}'),  // Import from @/lib/oauth/utils
  placeholder: 'Select account',
  required: true,
}
```

**Scopes:** Always use `getScopesForService(serviceId)` from `@/lib/oauth/utils` for `requiredScopes`. Never hardcode scope arrays — the single source of truth is `OAUTH_PROVIDERS` in `lib/oauth/oauth.ts`.

**Scope descriptions:** When adding a new OAuth provider, also add human-readable descriptions for all scopes in `SCOPE_DESCRIPTIONS` within `lib/oauth/utils.ts`.

**Service accounts (shared, app-level credentials):** A plain `oauth-input` already lets users *select* an existing service account — those credentials fold into the picker automatically (a Google service account created for any Google service appears in every Google block's picker). You only set `credentialKind` when you want to change the *connect* action:

```typescript
{
  id: 'credential',
  title: 'Account',
  type: 'oauth-input',
  serviceId: '{service}',
  requiredScopes: getScopesForService('{service}'),
  credentialKind: 'any',   // omit | 'service-account' | 'any'
}
```

- **omit (default):** lists OAuth accounts + any existing service accounts; the only connect action is "Connect account" (OAuth). Use this for the common "let users pick a service account someone set up elsewhere, but don't offer inline setup" case — no config needed.
- **`'service-account'`:** service-account credentials *only*, plus an inline setup action that opens the provider's connect modal. Use when a block accepts *only* an app credential.
- **`'any'`:** merged picker — OAuth accounts *and* service accounts in one grouped dropdown, with a connect action for each. Use when a block supports both (e.g. Slack: a personal account *or* a custom bot).

Optional companions: `credentialLabels` (override the picker's section/connect-row copy) and `allowServiceAccounts: true` (trigger-mode only — list service accounts, which triggers otherwise exclude; set only when the trigger's polling path can resolve a service-account token). The connect modal, provider families (Google JSON key, Atlassian token, token-paste, client-credential, Slack bot), and the preview gate are all resolved from `serviceAccountProviderId` — you don't wire them per block.

### OAuth deployment availability (required for integration blocks)

A visible tools-category block with OAuth is deployment-gated. Its `oauth-input.serviceId` is
projected into `packages/deployment-config/src/integrations.json`, then resolved through
`resolveOAuthClientCapabilityId()` in `packages/deployment-config/src/env-capabilities.ts`.

When adding or changing an OAuth integration block:

1. Keep exactly one distinct OAuth `serviceId` across the block's `oauth-input` subBlocks.
2. Confirm that service ID resolves to an entry in `OAUTH_CLIENT_CAPABILITIES`. Google and
   Microsoft service IDs intentionally share their provider-level capability; do not add duplicate
   entries for those aliases.
3. For a new capability, add its required client fields to `OAUTH_CLIENT_CAPABILITIES` and ensure
   every referenced field exists in the env schema in `apps/sim/lib/core/config/env.ts`. Then add
   the matching `text` or `secret` input modes to `OAUTH_CLIENT_SETUP_FIELDS` in
   `packages/sim-setup/src/capability-config.ts`. The CLI catalog is exhaustively typed and checked
   against the runtime field list; do not infer secrecy from the field name.
4. If the canonical OAuth service declares `serviceAccountProviderId`, run
   `bun run deployment-config:generate`; this regenerates the provider-ID facts in
   `packages/deployment-config/src/service-account-providers.generated.ts`. Never hand-edit that
   generated map. Add `deploymentRequirement` policy in
   `packages/deployment-config/src/service-account-metadata.ts` only when the service-account path
   is preview-gated or depends on the OAuth client fields; otherwise omit it.

Missing capability metadata is a runtime configuration error, not a reason to make the integration
silently available.

### Selectors (with dynamic options)
```typescript
// Channel selector (Slack, Discord, etc.)
{
  id: 'channel',
  title: 'Channel',
  type: 'channel-selector',
  selectorKey: '{service}.channels',
  serviceId: '{service}',
  placeholder: 'Select channel',
  dependsOn: ['credential'],
}

// Project selector (Jira, etc.)
{
  id: 'project',
  title: 'Project',
  type: 'project-selector',
  selectorKey: '{service}.projects',
  serviceId: '{service}',
  dependsOn: ['credential'],
}

// File selector (Google Drive, etc.)
{
  id: 'file',
  title: 'File',
  type: 'file-selector',
  selectorKey: '{service}.files',
  serviceId: '{service}',
  mimeType: 'application/pdf',
  dependsOn: ['credential'],
}

// User selector
{
  id: 'user',
  title: 'User',
  type: 'user-selector',
  selectorKey: '{service}.users',
  serviceId: '{service}',
  dependsOn: ['credential'],
}
```

### Other Types
```typescript
// Switch/toggle
{ id: 'enabled', type: 'switch' }

// Slider
{ id: 'temperature', title: 'Temperature', type: 'slider', min: 0, max: 2, step: 0.1 }

// Table (key-value pairs)
{ id: 'headers', title: 'Headers', type: 'table', columns: ['Key', 'Value'] }

// File upload
{
  id: 'files',
  title: 'Attachments',
  type: 'file-upload',
  multiple: true,
  acceptedTypes: 'image/*,application/pdf',
}
```

## File Input Handling

When your block accepts file uploads, use the basic/advanced mode pattern with `normalizeFileInput`.

### Basic/Advanced File Pattern

```typescript
// Basic mode: Visual file upload
{
  id: 'uploadFile',
  title: 'File',
  type: 'file-upload',
  canonicalParamId: 'file',  // Both map to 'file' param
  placeholder: 'Upload file',
  mode: 'basic',
  multiple: false,
  required: true,
  condition: { field: 'operation', value: 'upload' },
},
// Advanced mode: Reference from other blocks
{
  id: 'fileRef',
  title: 'File',
  type: 'short-input',
  canonicalParamId: 'file',  // Both map to 'file' param
  placeholder: 'Reference file (e.g., {{file_block.output}})',
  mode: 'advanced',
  required: true,
  condition: { field: 'operation', value: 'upload' },
},
```

**Keep the pair to one logical thing.** Basic is the file upload, advanced is *only* a reference to
a file from a previous block. Gmail attachments are the reference implementation
(`apps/sim/blocks/blocks/gmail.ts` — `attachmentFiles` / `attachments`).

Do not overload the advanced side with alternate identifiers (a remote URL, a provider asset ID, a
path). A subblock whose meaning changes based on what the string looks like is impossible to reason
about, forces the params function to sniff the value, and makes the field's type meaningless. Give
each alternative its own subblock outside the pair:

```typescript
// ✓ Good — the pair is "a file"; other sources are their own fields
{ id: 'mediaFile',    type: 'file-upload', canonicalParamId: 'media', mode: 'basic' },
{ id: 'mediaFileRef', type: 'short-input', canonicalParamId: 'media', mode: 'advanced' },
{ id: 'mediaId',      type: 'short-input', mode: 'advanced' },  // separate concept
{ id: 'mediaLink',    type: 'short-input', mode: 'advanced' },  // separate concept

// ✗ Bad — one field meaning three things, resolved by guessing
{ id: 'mediaRef', type: 'short-input', canonicalParamId: 'media', mode: 'advanced',
  placeholder: 'File reference, media ID, or public URL' },
```

When several fields are mutually exclusive alternatives, mark them all `required: false` and enforce
"exactly one" at execution — a conditionally-required canonical pair rejects the workflow before the
other paths ever get a chance to supply the value.

**Constraints (block-wide):**
- `canonicalParamId` must not equal any subblock `id` in the block.
