connector-sdk-submit

connector-sdk-submit is a skill for Claude Code from fivetran/connector_sdk_tools. It costs 45 tokens per session (3,123 once invoked), scanned A, original, MIT.

A review skill for the design of ESP32 firmware, the software that runs on ESP32 microcontrollers. It checks embedded-system concerns such as task memory, interrupt rules, pins, peripherals, networking, storage, logging, and build settings.

In plain words
What is it for?
Use it to review FreeRTOS task safety, stack sizes, GPIO conflicts, risky configuration options, partition tables, error handling, and peripheral behavior before changing the firmware.
Why use it?
It helps find hardware- and real-time-specific design problems that ordinary source-code review can miss. It reports whether the design passes, passes with notes, or fails, and is read-only unless fixes are requested.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-sdk-submit 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 today.

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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Submit Connector SDK Contribution

Use this skill immediately before a contributor opens their first Connector SDK example-connector pull request. Its authority is the selected target repository's GitHub review instructions under .github/instructions. Do not use external examples or generic Python conventions as a substitute.

Establish the scope and authority

  1. Ask for the connector directory if it was not supplied. Identify the enclosing Git repository.
  2. Choose the PR destination using these repository rules:
    • Use fivetran/community_connectors for a new, standalone connector for a specific source; or a focused bug fix, reliability/performance improvement, or documentation update to an existing Community Connector. New connectors belong in a top-level connector directory and must be listed in that repository's root README.md.
    • Use fivetran/connector_sdk for a Connector SDK template, quickstart/tutorial, reusable generic SDK pattern. Place examples in the repository's existing examples/.
    • If the work could be treated as either a reusable SDK example/pattern or a standalone source connector, prioritize fivetran/community_connectors. Submit the standalone connector there; do not split the work or create PRs in both repositories.
    • If the files already belong to one repository, keep the PR in that repository.
  3. State the selected repository and the rule that led to the decision. If none of the rules applies, ask the contributor to choose; do not guess.
  4. Before reviewing or editing, read these instruction files from the selected target repository—either fivetran/community_connectors or fivetran/connector_sdk:
    • .github/instructions/configuration-review.instructions.md
    • .github/instructions/python-review.instructions.md
    • .github/instructions/readme-markdown.instructions.md If the contribution is in the selected repository, use its local files. Otherwise, ask the contributor for a checkout path for that repository.
  5. If the selected target repository or its instruction checkout is unavailable, explain the missing item in plain language and offer to obtain it. For example: “I need a local checkout of the selected repository to apply its submission rules. May I clone the upstream repository, or would you prefer to fork it first?” Wait for approval before cloning, forking, authenticating, or changing remotes.
  6. Confirm that the target is a connector/example directory containing connector.py. If it is not, stop and explain that this skill supports connector/example submissions only; do not apply it to documentation-only, tooling, or repository-maintenance changes.
  7. Inspect the connector's changed files and its relevant files: connector.py, README.md, and dependency files, excluding configuration contents and raw configuration diffs. Discover configuration-like files by path only at this stage; defer reading their contents until the submission configuration has been selected and can be scanned locally without exposing values, as described below. Do not inspect or print real local configuration files such as configuration_local.json.
