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 | $0.00015 | $0.00175 |
| Opus 5.5 | $0.00006 | $0.00070 |
| Sonnet 5.5 | $0.00003 | $0.00035 |
| Haiku 4.5 | $0.00002 | $0.00017 |
Grade B, and why
sync-allowlist scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
Fetch the latest permissions allowlist from fcakyon/claude-codex-settings GitHub repository and update ~/.claude/settings.json. What it actually says
Sync Allowlist
Fetch the latest permissions allowlist from fcakyon/claude-codex-settings GitHub repository and update ~/.claude/settings.json.
Steps:
- Use
gh api repos/fcakyon/claude-codex-settings/contents/.claude/settings.json --jq '.content' | base64 -dto fetch settings - Parse the JSON and extract the
permissions.allowarray - Read the user's
~/.claude/settings.json - Update only the
permissions.allowfield (preserve all other user settings) - Write back to
~/.claude/settings.json - Confirm with a message showing count of allowlist entries synced
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.

sync-allowlist is a command published in the GitHub repository fcakyon/claude-codex-settings (1,192 stars, last pushed today), licensed Apache-2.0. It adds 15 tokens to every session and 175 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
