[add-skill]: /docs/server-sdks/reference/typescript/agents/agent-base/add-skill [sw-search]: /docs/server-sdks/reference/typescript/agents/cli/sw-search [infogathereragent]: /docs/server-sdks/reference/typescript/agents/prefabs#infogathereragent [skillbase]: /docs/server-sdks/reference/typescript/agents/skill-base [ref-datamap]: /docs/server-sdks/reference/typescript/agents/data-map Skills are pluggable capabilities that add tools to your agent. Import a skill class, instantiate it with optional configuration, and pass the instance to [`addSkill()`][add-skill]. Each skill registers one or more SWAIG functions automatically and injects prompt sections, hints, and global data. ```typescript {8,11-14} import { AgentBase, DateTimeSkill, WebSearchSkill } from '@signalwire/sdk'; const agent = new AgentBase({ name: 'my-agent', route: '/' }); agent.setPromptText('You are a helpful assistant.'); // No-config skill await agent.addSkill(new DateTimeSkill()); // Skill with parameters await agent.addSkill(new WebSearchSkill({ num_results: 5, safe_search: 'high', })); agent.run(); ``` ## Skills Summary | Skill | Class | Tools | Env Vars Required | Multi-Instance | | ----------------------------------------------------------------------------------------------------- | --------------------------- | ------- | ----------------- | -------------- | | [`datetime`](/docs/server-sdks/reference/typescript/agents/skills/datetime) | `DateTimeSkill` | 2 | No | No | | [`math`](/docs/server-sdks/reference/typescript/agents/skills/math) | `MathSkill` | 1 | No | No | | [`joke`](/docs/server-sdks/reference/typescript/agents/skills/joke) | `JokeSkill` | 1 | No | No | | [`weather_api`](/docs/server-sdks/reference/typescript/agents/skills/weather-api) | `WeatherApiSkill` | 1 | Yes | No | | [`web_search`](/docs/server-sdks/reference/typescript/agents/skills/web-search) | `WebSearchSkill` | 1 | Yes | Yes | | [`wikipedia_search`](/docs/server-sdks/reference/typescript/agents/skills/wikipedia-search) | `WikipediaSearchSkill` | 1 | No | No | | [`google_maps`](/docs/server-sdks/reference/typescript/agents/skills/google-maps) | `GoogleMapsSkill` | 4 | Yes | No | | [`play_background_file`](/docs/server-sdks/reference/typescript/agents/skills/play-background-file) | `PlayBackgroundFileSkill` | 1-3 | No | Yes | | [`swml_transfer`](/docs/server-sdks/reference/typescript/agents/skills/swml-transfer) | `SwmlTransferSkill` | 1-2 | No | Yes | | [`datasphere`](/docs/server-sdks/reference/typescript/agents/skills/datasphere) | `DataSphereSkill` | 1 | Yes | Yes | | [`datasphere_serverless`](/docs/server-sdks/reference/typescript/agents/skills/datasphere-serverless) | `DataSphereServerlessSkill` | 1 | Yes | Yes | | [`native_vector_search`](/docs/server-sdks/reference/typescript/agents/skills/native-vector-search) | `NativeVectorSearchSkill` | 1 | No | Yes | | [`info_gatherer`](/docs/server-sdks/reference/typescript/agents/skills/info-gatherer) | `InfoGathererSkill` | 2 | No | Yes | | [`api_ninjas_trivia`](/docs/server-sdks/reference/typescript/agents/skills/api-ninjas-trivia) | `ApiNinjasTriviaSkill` | 1 | Yes | Yes | | [`spider`](/docs/server-sdks/reference/typescript/agents/skills/spider) | `SpiderSkill` | 3 | No | Yes | | [`ask_claude`](/docs/server-sdks/reference/typescript/agents/skills/ask-claude) | `AskClaudeSkill` | 1 | Yes | No | | [`claude_skills`](/docs/server-sdks/reference/typescript/agents/skills/claude-skills) | `ClaudeSkillsSkill` | Dynamic | No | Yes | | [`custom_skills`](/docs/server-sdks/reference/typescript/agents/skills/custom-skills) | `CustomSkillsSkill` | Dynamic | No | No | | [`mcp_gateway`](/docs/server-sdks/reference/typescript/agents/skills/mcp-gateway) | `McpGatewaySkill` | 1 | No | No | ## Configuration All skills accept configuration via a config object passed to the skill constructor. Skills with an `env_var` fallback on a parameter read from `process.env` when the parameter is not provided directly. ```typescript {4} import { WebSearchSkill } from '@signalwire/sdk'; // Direct configuration const skill = new WebSearchSkill({ num_results: 5, safe_search: 'high' }); // Environment variable fallback (api_key falls back to GOOGLE_SEARCH_API_KEY, // search_engine_id falls back to GOOGLE_SEARCH_CX) process.env.GOOGLE_SEARCH_API_KEY = 'YOUR_KEY'; process.env.GOOGLE_SEARCH_CX = 'YOUR_ENGINE_ID'; const skillWithEnv = new WebSearchSkill({ num_results: 5 }); ``` ### SWAIG Field Overrides Override SWAIG function metadata for any skill by including a `swaig_fields` key: ```typescript {6-11} import { AgentBase, DateTimeSkill } from '@signalwire/sdk'; const agent = new AgentBase({ name: 'assistant', route: '/assistant' }); agent.setPromptText('You are a helpful assistant.'); await agent.addSkill(new DateTimeSkill({ swaig_fields: { fillers: { 'en-US': ['Let me check the time...', 'One moment...'] }, secure: false, }, })); agent.run(); ``` ### Multi-Instance Skills Skills that support multiple instances (`SUPPORTS_MULTIPLE_INSTANCES = true`) can be added to the same agent more than once with different `tool_name` values: ```typescript {6-9,10-13} import { AgentBase, DataSphereSkill } from '@signalwire/sdk'; const agent = new AgentBase({ name: 'assistant', route: '/assistant' }); agent.setPromptText('You are a helpful assistant.'); await agent.addSkill(new DataSphereSkill({ tool_name: 'search_products', document_id: 'doc_products', count: 3, })); await agent.addSkill(new DataSphereSkill({ tool_name: 'search_policies', document_id: 'doc_policies', count: 5, })); agent.run(); ``` ### Base Parameters Every skill inherits these parameters from `SkillBase`: **`swaig_fields`** `object` Additional SWAIG fields to merge into each tool definition provided by this skill (e.g., `fillers`, `secure`). --- **`skip_prompt`** `boolean` — default: false When `true`, suppress all prompt sections from this skill. --- --- ## Extending SkillBase Create custom skills by extending [`SkillBase`][skillbase] and registering them with the `SkillRegistry`. ### Defining a Custom Skill ```typescript {10-14} import { SkillBase, FunctionResult } from '@signalwire/sdk'; import type { SkillToolDefinition, SkillPromptSection, ParameterSchemaEntry, } from '@signalwire/sdk'; export class StockPriceSkill extends SkillBase { // Identity is declared with static class constants. static override SKILL_NAME = 'stock_price'; static override SKILL_DESCRIPTION = 'Look up current stock prices.'; static override SKILL_VERSION = '1.0.0'; static override REQUIRED_ENV_VARS = ['STOCK_API_KEY'] as const; static override getParameterSchema(): Record { return { ...super.getParameterSchema(), api_key: { type: 'string', description: 'Stock API key.', hidden: true, env_var: 'STOCK_API_KEY', required: true, }, }; } override getTools(): SkillToolDefinition[] { return [ { name: 'get_stock_price', description: 'Get the current price of a stock by ticker symbol.', parameters: { symbol: { type: 'string', description: 'Stock ticker symbol (e.g., "AAPL", "GOOG").', }, }, required: ['symbol'], handler: async (args: Record) => { const symbol = args.symbol as string; // Your implementation here return new FunctionResult( 'The current price of ' + symbol + ' is $150.00.', ); }, }, ]; } protected override _getPromptSections(): SkillPromptSection[] { return [ { title: 'Stock Prices', body: 'You can look up current stock prices.', bullets: [ 'Use the get_stock_price tool when the user asks about a stock price.', 'Provide the stock ticker symbol (e.g., AAPL for Apple).', ], }, ]; } } ``` ### Registering with SkillRegistry ```typescript {4-5} import { SkillRegistry } from '@signalwire/sdk'; import { StockPriceSkill } from './stock-price-skill.js'; const registry = SkillRegistry.getInstance(); registry.register(StockPriceSkill); // pass the class; name comes from SKILL_NAME ``` ### Using a Custom Skill ```typescript {7} import { AgentBase } from '@signalwire/sdk'; import { StockPriceSkill } from './stock-price-skill.js'; const agent = new AgentBase({ name: 'finance-bot', route: '/' }); agent.setPromptText('You are a financial assistant.'); await agent.addSkill(new StockPriceSkill()); agent.run(); ``` For more details on the skill base class, see [`SkillBase`][skillbase]. --- ## All Skills #### [DateTimeSkill](/docs/server-sdks/reference/typescript/agents/skills/datetime) Get the current date and time with optional timezone support. #### [MathSkill](/docs/server-sdks/reference/typescript/agents/skills/math) Evaluate mathematical expressions safely. #### [JokeSkill](/docs/server-sdks/reference/typescript/agents/skills/joke) Tell jokes from a built-in collection. #### [WeatherApiSkill](/docs/server-sdks/reference/typescript/agents/skills/weather-api) Get current weather conditions using OpenWeatherMap. #### [WebSearchSkill](/docs/server-sdks/reference/typescript/agents/skills/web-search) Search the web using Google Custom Search. #### [WikipediaSearchSkill](/docs/server-sdks/reference/typescript/agents/skills/wikipedia-search) Search Wikipedia for article summaries. #### [GoogleMapsSkill](/docs/server-sdks/reference/typescript/agents/skills/google-maps) Get directions and search for places using Google Maps. #### [PlayBackgroundFileSkill](/docs/server-sdks/reference/typescript/agents/skills/play-background-file) Control background audio playback during calls. #### [SwmlTransferSkill](/docs/server-sdks/reference/typescript/agents/skills/swml-transfer) Transfer calls using SWML transfer actions. #### [DataSphereSkill](/docs/server-sdks/reference/typescript/agents/skills/datasphere) Search SignalWire DataSphere documents. #### [DataSphereServerlessSkill](/docs/server-sdks/reference/typescript/agents/skills/datasphere-serverless) Search DataSphere documents serverlessly. #### [NativeVectorSearchSkill](/docs/server-sdks/reference/typescript/agents/skills/native-vector-search) In-memory document search using word overlap scoring. #### [InfoGathererSkill](/docs/server-sdks/reference/typescript/agents/skills/info-gatherer) Collect structured information from the user. #### [ApiNinjasTriviaSkill](/docs/server-sdks/reference/typescript/agents/skills/api-ninjas-trivia) Fetch trivia questions from API Ninjas. #### [SpiderSkill](/docs/server-sdks/reference/typescript/agents/skills/spider) Scrape webpage content using the Spider API. #### [AskClaudeSkill](/docs/server-sdks/reference/typescript/agents/skills/ask-claude) Send prompts to Anthropic's Claude AI. #### [ClaudeSkillsSkill](/docs/server-sdks/reference/typescript/agents/skills/claude-skills) Load Claude Code-style SKILL.md files as tools. #### [CustomSkillsSkill](/docs/server-sdks/reference/typescript/agents/skills/custom-skills) Register user-defined tools from configuration. #### [McpGatewaySkill](/docs/server-sdks/reference/typescript/agents/skills/mcp-gateway) Model Context Protocol server integration.
