In plain words
What is it for?
Use them to build or serve the library, inspect playground demos, run code-quality checks and find the main classes, settings and feature modules.
Why use it?
They explain the commands, source layout and test playground so developers can build the library and check changes in working examples.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is tech-systems/panes's own configuration. It tells Claude Code how to work on panes itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything panes configures →

Token cost

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.

Security

Grade A, and why

panes 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 2mo 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.

Project Overview

Cupertino Panes is a TypeScript library that creates multi-functional modals, cards, and panes with touch technologies. It provides native iOS-style behaviors and animations for web applications.

Development Commands

Build and Development

  • npm run build - Production build (creates minified bundles in /dist)
  • npm run serve - Development server with live reload on port 3000
  • npm run tslint - Run TSLint for code quality checks
  • npm run changelog - Generate changelog using conventional commits

Testing Environment

  • Use npm run serve to test changes in the /playground directory
  • Visit http://localhost:3000/playground/ to view examples
  • Multiple demo pages available in /playground for testing different features

Code Architecture

Core Structure

  • Main Class: CupertinoPane in /src/cupertino-pane.ts - Primary API class
  • Settings: Configuration managed through /src/settings.ts with TypeScript interfaces in /src/models.ts
  • Module System: Modular architecture with feature modules in /src/modules/

Key Components

  • Breakpoints: /src/breakpoints.ts - Manages pane positioning and snapping points
  • Transitions: /src/transitions.ts - Handles animations and state transitions
  • Events: /src/events/ - Touch events, keyboard events, and resize handling
  • Device Detection: /src/device.ts - Platform-specific optimizations
  • Support Detection: /src/support.ts - Feature detection utilities

Module System

Available modules (all in /src/modules/):

  • backdrop.ts - Backdrop overlay functionality
  • fit-height.ts - Auto-height calculation
  • follower.ts - Element following behavior
  • horizontal.ts - Horizontal pane orientation

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.
