scaffold: Instructions file for Claude Code

CLAUDE.md

scaffold CLAUDE.md is an instructions file for Claude Code from zigrivers/scaffold. It costs 9,299 tokens per session, scanned C, original, MIT.

Project instructions for a Claude Code plugin and TypeScript command-line tool that assembles software-project prompts from Markdown pipeline files. It emphasizes simple changes, test-first development, and verifying behavior before completion.

In plain words
What is it for?
Use it when working on the zigrivers/scaffold repository, especially its pipeline content, TypeScript CLI, Claude Code plugin structure, tests, and project documentation.
Why use it?
It gives an AI coding assistant a shared understanding of the project’s structure, priorities, and source-of-truth files. This reduces inconsistent changes and skipped verification work.

Written for Claude Code: PostToolUse hook event. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions subagents.

This is zigrivers/scaffold's own configuration. It tells Claude Code how to work on scaffold 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 scaffold 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 C, and why

scaffold CLAUDE.md scanned grade C with 1 finding 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.

CLAUDE.md

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

Core Principles

  • Simplicity First: Make every change as simple as possible. Minimal code, minimal impact. Don't over-engineer.
  • No Laziness: Find root causes. No temporary fixes. Senior developer standards.
  • TDD Always: Write failing tests first, then make them pass, then refactor. No exceptions.
  • Prove It Works: Never mark a task complete without demonstrating correctness — tests pass, logs clean, behavior verified.

Project Overview

This is a prompt pipeline — a curated sequence of structured meta-prompts used to scaffold new software projects with Claude Code and other supported AI tools. The pipeline is defined as individual .md files in content/pipeline/, organized into 16 phases, and assembled into full prompts at runtime by the TypeScript CLI.

Structure

This repo is a Claude Code plugin (installable via /plugin marketplace add) and a TypeScript CLI distributed via npm and Homebrew.

Source of Truth

  • content/pipeline/ — 99 meta-prompt files organized into 16 phases (source of truth for pipeline steps)
  • content/tools/ — 12 tool meta-prompts (category: tool, stateless: true) orthogonal to the pipeline
  • content/knowledge/ — 301 domain expertise entries in 21 categories (injected into prompts during assembly)
  • content/skills/ — Skill templates with {{markers}} for multi-platform resolution
  • content/methodology/ — Preset configs (deep, mvp, custom, brownfield — brownfield is adopt-selected, not an init choice) plus project-type and domain overlays
  • src/types/frontmatter.ts — Canonical PHASES constant defining all 16 phase slugs, numbers, and display names

Legacy (v1)

The original v1 prompt content is archived at docs/archive/prompts-v1.md. It is not the source of truth — pipeline steps in content/pipeline/ are authoritative.

Plugin Structure

  • .claude-plugin/plugin.json — Plugin manifest (name: scaffold)
  • skills/ — Generated skills (built from content/skills/ templates; gitignored)
  • scripts/ — Bash utility scripts

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.
