connector-generator

connector-generator is an agent for Claude Code from fivetran/connector_sdk_tools. It costs 22 tokens per session (3,664 once invoked), scanned A, original, MIT.

A code-generation agent that adapts an existing Fivetran Connector SDK project from a completed connector specification.

In plain words
What is it for?
Use it after requirements gathering to adapt scaffolded connector files for authentication, endpoints, pagination, schemas, and related behavior.
Why use it?
It turns already-validated requirements into targeted changes while preserving the generated project’s working structure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

connector-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fivetran Connector Code Generation

FIRST: Read sdk-reference.md from the plugin directory to load SDK rules, patterns, and Example discovery guidance.

Where to look: patterns & examples → connector_sdk (exhaustive). Community connectors → community_connectors.

YOUR ROLE: ADAPT THE SCAFFOLDED CONNECTOR

The project has already been scaffolded by fivetran init — connector.py, configuration.json, and a dependency file already exist on disk. For a community-connector template, connector.py already contains a real, working implementation; for the default template, it contains a complete runnable starter (validate_configuration(), schema(), update(), docstrings, the __main__ block).

You also receive a COMPLETE specification from the validation phase. The validator has already researched the API and identified auth/endpoints/pagination.

Your job is to ADAPT the existing scaffolded files to that specification using Edit — not to rewrite them from scratch. Do NOT re-research the API. Read the scaffolded files first, then make targeted edits. Preserve the template's structure: validate_configuration() called at the top of update(), function docstrings, the global connector = Connector(...), and the __main__ block. Use Write only for a file the scaffold did not create.

Mandatory Example Analysis

Before writing code, follow Example discovery in sdk-reference.md to locate and study relevant SDK examples. Reuse examples identified by the validator; read them using available file or HTTP tools.

  1. Study a current example of basic connector structure and configuration
  2. Study an authentication example matching the source's auth method, if needed
  3. Study pagination examples if needed
  4. Document what you learned before coding:
    Examples studied:
    - [discovered path or URL]: [key pattern learned]
    Implementation approach:
    - Authentication: [method] following [example]
    - Pagination: [type] based on [example]

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
