basin

basin is a skill for Claude Code from fcakyon/claude-codex-settings. It costs 66 tokens per session (612 once invoked), scanned A, a copy of basin, Apache-2.0.

A Cloudflare data service for receiving events, transforming them, storing them in Apache Iceberg tables on R2 object storage, and querying them with SQL.

In plain words
What is it for?
Use it to build streaming data pipelines, manage catalogs of Iceberg tables, and run distributed SQL queries on stored events.
Why use it?
It provides one workflow for moving event data into managed tables and examining it with queries instead of handling each part separately.

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

basin 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 17d 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.

Origin

This is a copy

97% identical to basin — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 26 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cloudflare Basin

Basin ingests and transforms events, manages Apache Iceberg tables in R2, and queries them with distributed SQL. Start with the Basin overview and retrieve the relevant current docs before implementing changes, especially for limits, pricing, permissions, and CLI syntax. While PR #33850 remains open, use the proposed pages in that PR if the new URLs have not been published.

Rebrand

Cloudflare Data Platform is now Basin. Cloudflare Pipelines, R2 Data Catalog, and R2 SQL are now Basin Pipelines, Basin Catalog, and Basin SQL. Existing resources and configurations continue to work. The prior Wrangler command families also continue to work: wrangler pipelines, wrangler r2 bucket catalog, and wrangler r2 sql. Use the new Basin commands and documentation URLs in new guidance. Legacy API identifiers and metrics names may still use the old terms; check the current docs for deprecation details. The migration is documented in cloudflare-docs PR #33850.

Choose the workflow

Need Product Reference Current docs
Receive events, transform rows, and deliver to R2 Basin Pipelines Pipelines guide Basin Pipelines
Manage Iceberg metadata, table maintenance, and engine access Basin Catalog Catalog guide Basin Catalog
Query Iceberg tables with analytical SQL Basin SQL SQL guide Basin SQL

Typical flow: Basin Pipelines → Basin Catalog tables in R2 → Basin SQL or a compatible external engine. Begin with the Basin getting started guide for an end-to-end setup.

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.
