25 Tools & Skills.

Skills are the capabilities that make agents useful beyond conversation. The Intern ships with 25 tools across two categories: 11 Alpha Engine tools and 14 core tools.

Alpha Engine tools (11)

Advanced LLM-powered business intelligence tools: generate_sales_script, handle_objection, score_lead, analyze_pipeline (Sales), generate_negotiation_strategy, craft_counter_offer (Negotiation), review_contract, draft_legal_argument, synthesize_documents (Legal), competitor_analysis, generate_business_strategy (Strategy).

Skill configuration

Skills that require third-party access list their requirements in requiresAuth (e.g., ["google_calendar", "stripe", "twilio"]). Users connect these integrations in Settings → Integrations. Credentials are stored encrypted in users.preferences.

The Marketplace

Community-built skills are listed in the marketplace_templates table with ratings, download counts, and reviews. Browse at /dashboard/marketplace. The GET /api/marketplace endpoint returns all published templates with filtering by category and search.

Custom skills (SKILL.md)

Define your own skill in a markdown file: name, description, trigger phrases, step-by-step actions, and required tools. Upload via Settings → Workspace. No code required. The agent reads the file and knows how to use the skill immediately.

Tool calling

Under the hood, skills use Claude's tool calling API. The agent decides which tools to call, calls them in sequence, and synthesizes the results into a response. Tool calls are visible in real time in the chat UI and logged in messages.toolCalls.
