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 | $0.00784 | $0.00784 |
| Opus 5.5 | $0.00314 | $0.00314 |
| Sonnet 5.5 | $0.00157 | $0.00157 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
connector_sdk_tools GEMINI.md 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 1mo 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Routing
| User says | Action |
|---|---|
| "Build/create a connector for X" | Run /fivetran-connector-sdk:build-connector |
| "Help me connect to [data source]" | Run /fivetran-connector-sdk:build-connector |
| "Start from / use the community connector for X" | Run /fivetran-connector-sdk:build-connector (Phase 1 discovery finds the match and scaffolds it with fivetran init --template) |
| "Migrate my Fivetran Functions connector" / "Port this Lambda/Azure/GCP Function connector to Connector SDK" | Run /fivetran-connector-sdk:migrate-functions-connector |
| "Migrate my Meltano connector" / "Port this Singer tap to Connector SDK" | Run /fivetran-connector-sdk:migrate-meltano-connector |
| "Migrate my Airbyte connector" / "Port this Airbyte source to Connector SDK" | Run /fivetran-connector-sdk:migrate-airbyte-connector |
| "Test my connector" | Run /fivetran-connector-sdk:test-connector |
| "I'm getting an error..." / "fix my connector" / "help me change X" | Invoke the connector-fixer agent with the error details and user context. Do not handle code fixes in the main thread. |
| "Deploy my connector" | Run /fivetran-connector-sdk:deploy-connector |
| "Review / evaluate my connector" / "Is my connector production-ready?" | Run /fivetran-connector-sdk:evaluate-connector |
| "I already have a connector, help me test/modify it" | Use /fivetran-connector-sdk:test-connector, or invoke the connector-fixer agent for code changes |
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.
