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 | $0.00352 | $0.00352 |
| Opus 5 | $0.00176 | $0.00176 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
react-flow-skill CLAUDE.md 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.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Repo Is
This is a Claude Code skill (not an application). It provides expert React Flow (@xyflow/react v12+) guidance that Claude Code uses automatically when helping users build node-based UIs. The skill is installed via npx skills add framara/react-flow-skill.
Repository Structure
SKILL.md— The skill definition file. Contains the agent behavior contract (12 rules), triage template, routing map, common pitfalls, and verification checklist. This is the entry point Claude Code reads when the skill activates.references/— 14 topic-specific reference files that SKILL.md routes to based on user needs (migration, fundamentals, custom nodes/edges, state management, layouting, TypeScript, performance, troubleshooting, E2E testing, advanced patterns, common recipes, etc.)- No build system, tests, or application code — this repo is purely markdown-based reference content.
Editing Guidelines
- SKILL.md is the contract: Any behavioral rules, pitfall patterns, or verification steps belong here. Keep it concise — it's loaded into context on every activation.
- References are the depth: Detailed code examples, API patterns, and implementation guides go in
references/*.md. SKILL.md's routing map must stay in sync with reference file contents. - When adding a new reference topic: create
references/<topic>.md, add a routing entry in SKILL.md's "Routing map" section, and list it in SKILL.md's "References" section and README.md's feature list.
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.

react-flow-skill CLAUDE.md is an instructions file published in the GitHub repository framara/react-flow-skill (47 stars, last pushed 1mo ago), licensed MIT. It adds 352 tokens to every session, about $0.0018 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 2026-08-30.
