FramePlanner2: Instructions file for Claude Code

CLAUDE.md

FramePlanner2 CLAUDE.md is an instructions file for Claude Code from jonigata/FramePlanner2. It costs 1,451 tokens per session, scanned A, original, MIT.

Project instructions for FramePlanner, a Svelte web app for arranging manga images in editable frame layouts. They describe its commands, coding rules, architecture, and tests.

In plain words
What is it for?
Use them when developing, building, type-checking, or testing the Svelte canvas editor and its JSON-based frame data.
Why use it?
They give a coding agent the local conventions and commands needed to change the app without breaking its reusable library code.

Instructions file for Claude Code

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

This is jonigata/FramePlanner2's own configuration. It tells Claude Code how to work on FramePlanner2 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 FramePlanner2 configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { waitDialog } from '../utils/waitDialog';.

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

FramePlanner2 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.

Project Overview

FramePlanner is a manga creation tool that allows users to define manga frame structures as tree data (JSON) and arrange images within frames like windows. This is a Svelte-based web application with a complex layered canvas system for interactive manga editing.

Development Commands

Primary Commands

  • npm run dev - Start development server on http://localhost:5173
  • npm run dev-https - Start development server with HTTPS support
  • npm run build - Production build (runs stamp command first)
  • npm run devbuild - Development build without optimizations
  • npm run check - Run Svelte type checking

Testing

  • npm run vitest - Run Vitest test runner
  • Test files use .vitest.ts extension (see src/lib/layeredCanvas/tools/geometry/geometry.vitest.ts)
  • Test setup configured in test/setup.ts with fake IndexedDB and mocked Canvas APIs

Other Utilities

  • npm run stamp - Generate git log stamp (used in builds)
  • npm run deploy - Deploy to Cloudflare Pages (only from sns_main branch)
  • npm run webp - Convert images to WebP format

Architecture Overview

Core Systems

LayeredCanvas System (src/lib/layeredCanvas/)

  • Paper/Layer Architecture: Multi-layered rendering system where each "Paper" contains multiple "Layers"
  • Viewport Management: Handles canvas transformations, scaling, and coordinate conversions
  • Event Handling: Sophisticated pointer event system with depth-based layering
  • Key files: system/layeredCanvas.ts, system/paperArray.ts

Book Data Model (src/lib/book/)

  • Book Structure: Books contain Pages, Pages contain FrameTrees and Bubbles
  • History Management: Undo/redo system with tagged operations
  • Media Handling: Support for images, videos, and remote media references
  • Key files: book.ts, envelope.ts (for serialization)

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.
