API Connector Generator

--- name: api-connector-builder description: Build a new API connector or provider by matching the target repo's existing integration pattern exactly. Use when adding one more integration without inventing a second architecture. origin: ECC direct-port adaptation version: "1.0.0" --- # API Connector Builder Use this when the job is to add a repo-native integration surface, not just a generic HTTP client. The point is to match the host repository's pattern: - connector layout - config schema - auth model - error handling - test style - registration/discovery wiring ## When to Use - "Build a Jira connector for this project" - "Add a Slack provider following the existing pattern" - "Create a new integration for this API" - "Build a plugin that matches the repo's connector style" ## Guardrails - do not invent a new integration architecture when the repo already has one - do not start from vendor docs alone; start from existing in-repo connectors first - do not stop at transport code if the repo expects registry wiring, tests, and docs - do not cargo-cult old connectors if the repo has a newer current pattern ## Workflow ### 1. Learn the house style Inspect at least 2 existing connectors/providers and map: - file layout - abstraction boundaries - config model - retry / pagination conventions - registry hooks - test fixtures and naming ### 2. Narrow the target integration Define only the surface the repo actually needs: - auth flow - key entities - core read/write operations - pagination and rate limits - webhook or polling model ### 3. Build in repo-native layers Typical slices: - config/schema - client/transport - mapping layer - connector/provider entrypoint - registration - tests ### 4. Validate against the source pattern The new connector should look obvious in the codebase, not imported from a different ecosystem. ## Reference Shapes ### Provider-style ``text providers/ existing_provider/ __init__.py provider.py config.py ` ### Connector-style `text integrations/ existing/ client.py models.py connector.py ` ### TypeScript plugin-style `text src/integrations/ existing/ index.ts client.ts types.ts test.ts ` ## Quality Checklist - [ ] matches an existing in-repo integration pattern - [ ] config validation exists - [ ] auth and error handling are explicit - [ ] pagination/retry behavior follows repo norms - [ ] registry/discovery wiring is complete - [ ] tests mirror the host repo's style - [ ] docs/examples are updated if expected by the repo ## Related Skills - backend-patterns - mcp-server-patterns - github-ops`
