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 | $0.00112 | $0.00926 |
| Opus 5 | $0.00056 | $0.00463 |
| Sonnet 5 | $0.00022 | $0.00185 |
| Haiku 4.5 | $0.00011 | $0.00093 |
Grade A, and why
ultralytics-platform 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.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ultralytics Platform
Use ultralytics for YOLO training and inference. Use the generated ultralytics-platform Python
SDK for API resource work. It follows the same contract as the live API and handles authentication,
typed responses, retries, and errors.
Read the live contract
Before API work, check the generated API reference or
GET https://platform.ultralytics.com/openapi.json. Treat the live OpenAPI document as authoritative
when examples disagree. The shapes below match API and SDK v0.1.18, checked on 2026-08-27.
uv pip install -U "ultralytics-platform>=0.1.18"
export ULTRALYTICS_API_KEY=ul_... # Settings > API Keys
Platform() reads ULTRALYTICS_API_KEY. The ultralytics package also reads the key saved by
yolo login. Never print or commit a key.
Choose the interface
| Goal | Interface |
|---|---|
| Track a run that has not started | ultralytics training callback |
| Train with a Platform dataset or model | ultralytics with a ul:// URI |
| Manage datasets, models, training, exports, or deployments | ultralytics-platform SDK |
| Use another language or inspect a new field | Live OpenAPI |
Live training and ul:// URIs
Pass an owner-qualified project to stream a run:
from ultralytics import YOLO
YOLO("yolo26n.pt").train(data="coco8.yaml", epochs=100, project="owner/project", name="run1")
project= is required. Without it, the callback exits before creating a Platform run. Use the
owner prefix for a team workspace.
YOLO("ul://owner/project/model").train(data="ul://owner/datasets/dataset", epochs=100)
SDK
Use a context manager and owner/name paths. Keep returned IDs for operations that require them,
including image operations, upload assetId, training modelId, and export IDs.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ultralytics-platform is a skill published in the GitHub repository fcakyon/claude-codex-settings (1,127 stars, last pushed today), licensed Apache-2.0. It adds 112 tokens to every session and 926 once invoked, about $0.0006 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.
