feat(airweave): add airweave block

[EwanTauran]

Summary

Adds Airweave integration to Sim, enabling agents to search across 30+ connected data sources including Stripe, GitHub, Notion, Slack, HubSpot, Zendesk, and more through a unified semantic search API.

Airweave makes any app searchable by syncing data from various sources with minimal configuration. This integration allows Sim workflows to query internal company data, customer information, and business metrics from all connected sources in a single search.

What is Airweave?

Airweave is an open-source platform that provides unified search across multiple business applications. It:

• Connects to 30+ data sources: Stripe, GitHub, Notion, Slack, HubSpot, Zendesk, Linear, Jira, and more
• Syncs data automatically: Keeps internal knowledge up-to-date with incremental updates
• Semantic & keyword search: Uses vector embeddings for intelligent search with multiple retrieval strategies
• Multi-tenant architecture: Supports OAuth2 and API key authentication
• AI-powered answers: Can generate natural language answers from search results

Why This Integration Matters

Currently, Sim workflows that need to access company data require:

• Multiple tool blocks (one per data source)
• Complex workflow logic to aggregate results
• Separate API keys and configurations for each service

With Airweave, agents can:

• Search across all data sources with a single query
• Choose retrieval strategies (hybrid, neural, or keyword) for optimal results
• Get AI-generated summaries with the "Generate Answer" feature
• Improve relevance with LLM-powered reranking

Usage Examples

As Standalone Block

Search for customer feedback across all connected platforms:

blocks:
  - id: airweave1
    type: airweave
    params:
      collectionId: "customer-data"
      query: "complaints about billing in the last week"
      retrievalStrategy: "hybrid"
      limit: 25
      rerank: true
      apiKey: <env.AIRWEAVE_API_KEY>

As Agent Tool with AI Answers

Enable agents to get summarized answers from company knowledge:

blocks:
  - id: agent1
    type: agent
    params:
      model: "openai/gpt-4o"
      systemPrompt: "You are a customer support agent with access to all company data."
      tools:
        - type: airweave
          params:
            collectionId: "company-knowledge"
            generateAnswer: true
            apiKey: <env.AIRWEAVE_API_KEY>

Setup Requirements

1. Create Airweave account at https://app.airweave.ai
2. Get API key from Airweave dashboard
3. Create collection and connect data sources (Stripe, Slack, Notion, etc.)
4. Copy collection readable ID from Airweave
5. Use in Sim with the Airweave block or as an agent tool

Testing

• Tool and block configuration verified against Airweave API documentation
• Generated tool documentation using generate-docs script
• Block appears in toolbar under "tools" category
• Zero linter errors
• Follows SimStudio naming conventions

Reviewers should verify:

• Tool parameters match Airweave API contract
• Block UI renders correctly with all subBlocks
• Airweave block works and is query-able

@EwanTauran is attempting to deploy a commit to the Sim Team on Vercel.

A member of the Team first needs to authorize it.

running into some slight issues testing, when i run Sim locally I can't create blocks (not airweave, not any other block for that matter). so I can't test the integration and move forward. would be great if someone could help me out with this.
