claude-codex-settings is a collection of configurations and reusable extensions for Claude Code, OpenAI Codex, Cursor, and related coding tools. Developers use its skills, commands, hooks, agents, plugins, and MCP servers to shape coding-agent workflows and connect alternative model APIs. The catalogue entries are components of this collection that can be installed into supported coding tools.
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 | $0.00038 | $0.00465 |
| Opus 5.5 | $0.00015 | $0.00186 |
| Sonnet 5.5 | $0.00008 | $0.00093 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
k2 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.
This is a copy
98% identical to k2 — 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.
What it actually says
Cloudflare K2
K2 is a durable log for decoupling event producers and consumers. Start with the K2 overview, then retrieve the relevant current documentation before giving setup instructions, code, limits, availability, permissions, or API details. The docs are the source of truth over this skill. While cloudflare-docs PR #33858 remains open, use its proposed pages if the public URLs have not been published.
Documentation
| Task | Docs | Check for |
|---|---|---|
| Create a stream and try K2 | Get started | Prerequisites, setup sequence, current API examples |
| Understand streams and subscriptions | Concepts | Record model and delivery behavior |
| Configure a stream | Configuration | Inputs, authentication, CORS, retention |
| Produce from HTTP or a Worker | Produce records | Request and binding syntax, encoding, errors, retries |
| Consume through subscriptions | Consume records | Leases, acknowledgements, retries, errors |
| Size a stream or consumer | Limits | Current quotas and size limits |
Retrieve the matching pages above for each task and use their current examples. For capacity or cost questions, check current limits and any published pricing before quoting values. State when a requested pricing or availability detail is not yet published.
For SQL transformation and delivery to R2 Iceberg tables, use the basin skill. For task processing, consult Queues.
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.

k2 is a skill published in the GitHub repository fcakyon/claude-codex-settings (1,181 stars, last pushed yesterday), licensed Apache-2.0. It adds 38 tokens to every session and 465 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 98% identical to k2, differing in 1 line, and is treated as a copy.

lov-api-creator
A development workflow for adding an app's API gateway support to a uni-api FastAPI backend and its uni-app frontend. It creates grouped gateway endpoints and a shared frontend calling layer.
lov-integrate-lovstudio-llm-skill
An integration with LovStudio.AI’s OpenAI-compatible API for text chat, speech-to-text, speech translation, speech generation, and live audio sessions. It returns structured results that other application code can use.
lov-backend
A backend workflow for adding an app's API gateway endpoints to a uni-api project built with FastAPI. It creates the app's package and router, registers them, and places the endpoints in a documented group.
