Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.00889 |
| Opus 5 | $0.00042 | $0.00445 |
| Sonnet 5 | $0.00017 | $0.00178 |
| Haiku 4.5 | $0.00008 | $0.00089 |
Grade A, and why
project-scaffolder 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Scaffolder Skill
This skill provides templates and guidance for scaffolding new self-learning resource projects.
Templates
The following templates are available in this skill directory:
| Template | Purpose |
|---|---|
| plan-template.md | Project structure with Part/Chapter/Section hierarchy |
| task-template.md | Session-based task checklist mirroring plan.md |
| persona-template.md | Writer/Reader persona and code policy definitions |
| project-context-template.md | Target environment and reference URLs |
| claude-md-template.md | CLAUDE.md project instructions |
Workflow
1. Information Gathering
Before scaffolding, collect the following information:
- Topic: Subject of the learning resource
- Total Pages: Estimated page count (50/100/200+)
- Language: Primary language (ko/en)
- Target Audience: Experience level (beginner/intermediate/advanced)
- Target Environment: OS, tools, versions
2. File Generation Order
plan.md- Main structure document (use plan-template.md)task.md- Session-divided checklist (use task-template.md)persona.md- Writer/Reader definitions (use persona-template.md)project-context.md- Environment and references (use project-context-template.md)CLAUDE.md- Project instructions for Claude (use claude-md-template.md)
3. Structure Guidelines
Hierarchy
- Part: Major theme (50-100 pages), contains 3-6 chapters
- Chapter: Topic group (15-30 pages), contains 3-5 sections
- Section: Single concept (5-12 pages)
Page Allocation Formula
| Content Type | Percentage |
|---|---|
| Introduction/Overview | 5-8% |
| Core Content | 60-70% |
| Practice/Examples | 20-25% |
| Summary/Review | 5-8% |
4. Session Division Rules
When creating task.md, divide work into Claude Code sessions:
- 1 session = 3-5 sections or 20-40 pages
- Group sections within the same Chapter/Part
- Consider dependencies (prerequisite → subsequent)
- Mark session boundaries with HTML comments:
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

project-scaffolder is a skill published in the GitHub repository BitYoungjae/marketplace (6 stars, last pushed 3mo ago), licensed MIT. It adds 84 tokens to every session and 889 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…
miniapp
Build a tiny interactive HTML playground only when someone asks to see, play with, or step through a mechanism.
eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
master-yinguang
A reference-based assistant for questions about Yinguang and Pure Land Buddhism, a Buddhist tradition focused on faith, ethical living, and practice connected with rebirth in the Pure Land. It can answer in Yinguang’s historical teaching style.
