Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01640 |
| Opus 5 | $0.00029 | $0.00820 |
| Sonnet 5 | $0.00012 | $0.00328 |
| Haiku 4.5 | $0.00006 | $0.00164 |
Grade A, and why
migrate-functions-connector 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 9d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context: This plugin is for the Fivetran Connector SDK (CSDK). "CSDK" is shorthand for "Connector SDK".
Migrate a Fivetran Functions Connector to CSDK
FIRST: Read sdk-reference.md from the plugin directory to load SDK rules, operation names, schema constraints, configuration rules, and testing requirements.
Use this workflow to convert an existing Fivetran Functions connector into a Connector SDK project. Functions connector examples and migration references:
- Official docs: https://fivetran.com/docs/connectors/functions
- Public examples: https://github.com/fivetran/functions
When validating the migration workflow itself, use representative examples from the public repository:
api/aws_lambda/index.jsfor JavaScript AWS Lambda withrequest.secrets,request.state,insert,delete,schema, andhasMore.softDelete/aws-lambda.pyfor Python AWS Lambda with top-levelsoftDelete.Azure-Function/Pyhton/azure-function.pyfor Azure Function response wrapping.file/csv/aws_lambda/index.jsfor file parsing behavior.
Step 1: Locate the Source and Target
If the user did not provide a source path, ask for the directory or file containing the Functions connector. Accept AWS Lambda, Azure Functions, Google Cloud Functions, or standalone handler examples.
Find or create the target CSDK project:
- If the current directory already has
connector.py,configuration.json, andrequirements.txt, migrate in place. - If no CSDK project exists, ask for the target directory name, then scaffold it with
fivetran initbefore editing files. - Do not overwrite unrelated files.
Step 2: Inventory the Functions Connector
Read the source code and identify:
- Runtime and platform: AWS Lambda, Azure Functions, Google Cloud Functions, or other.
- Language: Python, JavaScript/Node.js, Java, or other.
- Handler entry point and provider glue.
- Configuration inputs from
request.secrets, environment variables, or cloud secret services. - State inputs from
request.state. - Output shape:
insert,delete,softDelete,schema,state,hasMore, and error handling. - Tables, primary keys, cursor fields, pagination, and incremental sync logic.
- Dependencies and source-specific client libraries.
- Any setup/test behavior separate from sync behavior.
- Source naming quirks and bugs. Preserve table/column/state names unless renaming is clearly intentional, then document the change.
What this file has done since we first saw it
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.

migrate-functions-connector is a skill published in the GitHub repository fivetran/connector_sdk_tools (87 stars, last pushed today), licensed MIT. It adds 58 tokens to every session and 1,640 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
