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 | $0.01201 | $0.01201 |
| Sonnet 5 | $0.00480 | $0.00480 |
| Haiku 4.5 | $0.00240 | $0.00240 |
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 7d 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

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.

cockroachdb-skills CLAUDE.md is an instructions file published in the GitHub repository cockroachlabs/cockroachdb-skills (21 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 2,401 tokens to every session, about $0.0120 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.
