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 | $0.00377 |
| Opus 5.5 | $0.00023 | $0.00151 |
| Sonnet 5.5 | $0.00011 | $0.00075 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
tavily-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 1mo 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
Tavily Search and Extract
Use Tavily MCP tools for web search and content retrieval operations.
Tool Selection
Tavily Search (mcp__tavily__tavily_search)
Use for:
- Keyword-based searches across the web
- Finding relevant pages and content
- Quick answer gathering
- Multiple result discovery
Best for: Initial research, finding sources, broad queries
Tavily Extract (mcp__tavily__tavily-extract)
Use for:
- Getting detailed content from specific URLs
- Deep analysis of page content
- Structured data extraction
- Following up on search results
Best for: In-depth analysis, specific URL content, detailed information
Hook Behavior
tavily_extract_to_advanced.py hook automatically upgrades extract calls to advanced mode for better accuracy when needed.
Integration Pattern
- Use
mcp__tavily__tavily_searchfor discovery phase - Analyze results to find relevant URLs
- Use
mcp__tavily__tavily-extractfor detailed content on specific URLs - Process extracted content for user needs
Environment Variables
Tavily MCP requires:
TAVILY_API_KEY- API key from Tavily (tvly-...)
Configure in shell before using the plugin.
Cost Considerations
- Search is cheaper than extract
- Use search to filter relevant URLs first
- Only extract URLs that are likely relevant
- Cache results when possible
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.

tavily-usage is a skill published in the GitHub repository fcakyon/claude-codex-settings (1,186 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 377 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.
