paperpress: Instructions file for Claude Code

CLAUDE.md

paperpress CLAUDE.md is an instructions file for Claude Code from rozetyp/paperpress. It costs 1,707 tokens per session, scanned A, original, MIT.

Repository guidance for Claude Code describes a Fastify server that detects a company's branding from its website and turns Markdown into a branded PDF through one HTTP request. It also documents the server's commands and architecture.

In plain words
What is it for?
Use it when changing this TypeScript API, checking its types, building or starting it, or working with its Prisma database schema.
Why use it?
It gives the coding agent project-specific rules and commands, including known gaps such as the lack of an automated test suite. This helps avoid inventing unsupported features or test commands.

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

paperpress 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 7d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

An API that detects a company's brand (logo, color, font) from its live URL and renders markdown into a PDF styled in that brand, in one HTTP call. A single Fastify process — REST API plus a hosted MCP endpoint (src/routes/mcp.ts), no separate package or install step.

Deliberately kept as a lean skeleton: this server, callable, nothing else. No payment processing (the credit system is a Postgres counter with no charge path), no automated test suite, no committed Prisma migrations (see Known gaps below). Don't add features toward a 1.0 unless explicitly asked — bug fixes and code-quality work are the useful contributions here.

Commands

npm run dev              # tsx watch src/index.ts — local dev server
npm run build             # tsc -> dist/
npm start                 # node dist/index.js (run build first)
npm run prisma:migrate    # prisma migrate dev (local schema changes)
npx tsc --noEmit          # typecheck only, no test suite exists — use this to verify changes

There is no test command — don't invent one; npx tsc --noEmit plus manual verification (see samples below) is the actual verification loop this repo uses.

Regenerating the example renders in samples/ (useful after touching src/render/):

npx tsx scripts/preview.ts              # renders samples/sample.md across all 5 themes + a few brand kits
npx tsx scripts/detect.ts <url> [...]    # CLI brand-detection debug; add RENDER_SAMPLE=1 to also render a PDF per URL

Architecture

Render pipeline (src/render/): markdown.ts (remark/rehype, allowDangerousHtml: false) produces HTML → a theme from themes/ (clean/executive/academic/technical/marketing, plus an optional per-request BrandKit) supplies the CSS → pdf.ts prints it with Playwright. detect.ts is the other consumer of the render layer: it navigates a URL and reads computed styles/DOM signals (CSS custom properties, CTA background colors, scored logo <img> candidates, computed font-family) to produce a BrandKit — no LLM or image analysis involved, it reads values the browser already computed.

Changes

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.
