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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00056 | $0.00181 |
| Opus 5 | $0.00028 | $0.00090 |
| Sonnet 5 | $0.00011 | $0.00036 |
| Haiku 4.5 | $0.00006 | $0.00018 |
Grade A, and why
paper-search-usage 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 yesterday.
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.
What it actually says
Paper Search MCP
Search academic papers across multiple platforms.
Supported Platforms
- arXiv (preprints)
- PubMed (biomedical)
- IEEE Xplore (engineering)
- Scopus (multidisciplinary)
- ACM Digital Library (computer science)
- Semantic Scholar (AI-powered)
Usage
Use mcp__paper-search__* tools to search papers by keywords, authors, or topics.
Best Practices
- Start with broad searches, then narrow down
- Use platform-specific searches for domain-specific papers
- Combine multiple sources for comprehensive literature reviews
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.

paper-search-usage is a skill published in the GitHub repository fcakyon/claude-codex-settings (1,127 stars, last pushed today), licensed Apache-2.0. It adds 56 tokens to every session and 181 once invoked, about $0.0003 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 2026-09-03.
