What is cockroachdb-skills CLAUDE.md?

Project guidance for a repository of CockroachDB skills, where CockroachDB is a distributed SQL database. The skills document operational procedures for areas such as migrations, schema design, performance, and database operations, with safety checks for data and availability.

Use it when creating, reviewing, or organizing skills for CockroachDB development and operations, including database changes that could affect stored data or service availability.

It gives coding agents a structured way to follow database expertise and safety rules instead of treating the repository as ordinary prompt documentation. It also directs them toward official CockroachDB documentation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02401	$0.02401
Opus 5.5	$0.00960	$0.00960
Sonnet 5.5	$0.00480	$0.00480
Haiku 4.5	$0.00240	$0.00240

Security

Grade A, and why

cockroachdb-skills CLAUDE.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 2mo 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.

Project Overview

This is the CockroachDB Skills repository—a curated collection of Agent Skills that encode CockroachDB operational expertise. Skills are structured, machine-executable capabilities following the Agent Skills Specification. They enable AI agents to deliver contextually aware, production-grade CockroachDB operations.

Core Concepts:

Skills are NOT just prompts or documentation—they encode operational reasoning and procedural knowledge
Each skill addresses ONE specific operational task with clear boundaries
Skills reference official CockroachDB docs rather than duplicating them
Skills include safety guardrails for operations affecting data or availability

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.
