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 | $0.00127 | $0.03312 |
| Opus 5 | $0.00063 | $0.01656 |
| Sonnet 5 | $0.00025 | $0.00662 |
| Haiku 4.5 | $0.00013 | $0.00331 |
Grade A, and why
vercel-react-view-transitions 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 2d 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.

How it starts
The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React View Transitions
Animate between UI states using the browser's native document.startViewTransition. Declare what with <ViewTransition>, trigger when with startTransition / useDeferredValue / Suspense, control how with CSS classes. Unsupported browsers skip animations gracefully.
When to Animate
Every <ViewTransition> should communicate a spatial relationship or continuity. If you can't articulate what it communicates, don't add it.
Implement all applicable patterns from this list, in this order:
| Priority | Pattern | What it communicates |
|---|---|---|
| 1 | Shared element (name) |
"Same thing — going deeper" |
| 2 | Suspense reveal | "Data loaded" |
| 3 | List identity (per-item key) |
"Same items, new arrangement" |
| 4 | State change (enter/exit) |
"Something appeared/disappeared" |
| 5 | Route change (page-level) | "Going to a new place" |
This is an implementation order, not a "pick one" list. Implement every pattern that fits the app. Only skip a pattern if the app has no use case for it.
Choosing Animation Style
| Context | Animation | Why |
|---|---|---|
| Hierarchical navigation (list → detail) | Type-keyed nav-forward / nav-back |
Communicates spatial depth |
| Lateral navigation (tab-to-tab) | Bare <ViewTransition> (fade) or default="none" |
No depth to communicate |
| Suspense reveal | enter/exit string props |
Content arriving |
| Revalidation / background refresh | default="none" |
Silent — no animation needed |
Reserve directional slides for hierarchical navigation (list → detail) and ordered sequences (prev/next photo, carousel, paginated results). For ordered sequences, the direction communicates position: "next" slides from right, "previous" from left. Lateral/unordered navigation (tab-to-tab) should not use directional slides — it falsely implies spatial depth.
Availability
- Next.js: Do not install
react@canary— the App Router already bundles React canary internally.ViewTransitionworks out of the box.npm ls reactmay show a stable-looking version; this is expected. - Without Next.js: Install
react@canary react-dom@canary(ViewTransitionis not in stable React). - Browser support: Chromium 125+ (React needs the v2 object form of
startViewTransition), Firefox 144+, Safari 18.2+. Graceful degradation on unsupported browsers.
What ships with it
5 files 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.

vercel-react-view-transitions is a skill published in the GitHub repository fcakyon/claude-codex-settings (1,127 stars, last pushed yesterday), licensed Apache-2.0. It adds 127 tokens to every session and 3,312 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.
