Api Connector Builder

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.

What is this skill?

Use this when the job is to add a repo-native integration surface, not just a generic HTTP client.

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"

The point is to match the host repository's pattern:

  • connector layout
  • config schema
  • auth model
  • error handling
  • test style
  • registration/discovery wiring

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.

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
