appshot: Instructions file for Claude Code

CLAUDE.md

appshot CLAUDE.md is an instructions file for Claude Code from trunghaiy/appshot. It costs 308 tokens per session, scanned A, original, MIT.

Project instructions for Appshot, a tool that creates preview videos and images for mobile apps. The instructions describe its fixed iPhone-sized video canvas, source folders, build commands, and commit rules.

In plain words
What is it for?
Use them when developing Appshot scenes, app screenshots, video output, shared animation components, or project documentation.
Why use it?
They give a coding agent the project-specific constraints needed to change or build Appshot correctly. This reduces mistakes such as using the wrong video dimensions or editing generated files.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is trunghaiy/appshot's own configuration. It tells Claude Code how to work on appshot 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 appshot 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

appshot 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 1mo 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

Appshot — Claude Code Project Brief

App Store preview video generator for mobile apps (iOS/Android). AI skills scan a target app's codebase, propose a narrative, and write custom Remotion scene components using shared animation primitives.

  • Creator: Kian Nguyen
  • License: MIT

Key constraint

All video output is 886×1920px (App Store native for iPhone 6.7"). Every sizing rule in the skills and components is calibrated for this canvas width. PhoneFrame scale: 1.5. Text outside PhoneFrame: body 24px+, titles 34px+.

Where things live

  • template/src/components/ — 10 animation primitives (the product)
  • skills/appshot-core/ — extraction, config schema, primitives catalog
  • skills/appshot-videos/ — video creative director + references/code-guide.md
  • skills/appshot-images/ — screenshot creative director
  • .claude/skills/ — auto-populated by npx skills add, do NOT edit directly

Build

npm run dev      # Remotion Studio preview
npm run build    # Render 886×1920 MP4 (H.264, CRF 18, yuv420p, bt709)

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.
