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.

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 | $0.00057 | $0.00428 |
| Opus 5.5 | $0.00023 | $0.00171 |
| Sonnet 5.5 | $0.00011 | $0.00086 |
| Haiku 4.5 | $0.00006 | $0.00043 |
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 11d 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.
What it actually says
Search and read papers
Run Paper Search CLI through the shell. If paper-search is unavailable, follow setup.
Find papers
paper-search search 'object detection' -s fast -n 5
paper-search search 'object detection' -s arxiv,crossref -n 5
paper-search sources
Search returns JSON. Check errors for partial failures and retain source identifiers and URLs. Try alternate terms and multiple sources before concluding that no papers exist. Discover source names with paper-search sources; use explicit -s ieee, -s scopus, or -s wos only with configured credentials.
Look up, download, and read
paper-search tool get_crossref_paper_by_doi 10.1038/nature12373
paper-search download arxiv 1706.03762 -o ./downloads
paper-search read arxiv 1706.03762 -o ./downloads
paper-search tool get_citing_papers 10.1038/nature12373
paper-search tool get_referenced_papers 10.1038/nature12373
Citation commands accept a DOI or OpenAlex work ID, not a title. Check pagination and truncation metadata before treating a citation list as complete. Use paper-search tool --help and paper-search tool <operation> --help to discover other operations and their arguments.
Verify author names, venue, and year against the published paper or official record. For numerical claims, inspect the PDF's actual table or figure; extracted text can lose layout. Do not treat a search snippet as evidence for a result.
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 (1,189 stars, last pushed today), licensed Apache-2.0. It adds 57 tokens to every session and 428 once invoked, about $0.0002 per session on Opus 5.5. 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.
