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 | $0.00016 | $0.05465 |
| Opus 5 | $0.00008 | $0.02733 |
| Sonnet 5 | $0.00003 | $0.01093 |
| Haiku 4.5 | $0.00002 | $0.00547 |
Grade A, and why
create-skill 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 8d 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 — 576 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Onboarding Awareness (CHECK BEFORE STARTING)
Before creating a skill, AI MUST check stats.pending_onboarding for learn_skills:
Pre-Flight Check (MANDATORY)
Check if learn_skills is in stats.pending_onboarding. If present AND this is user's FIRST skill:
💡 Before creating your first skill, would you like a quick 10-minute tutorial
on what makes workflows "skill-worthy"? It covers:
- The 3-criteria skill-worthiness framework
- How skills are structured (SKILL.md, scripts/, references/)
- How AI triggers skills automatically
Say 'learn skills' to start the tutorial, or 'skip' to create directly.
If user says 'skip': Proceed with skill creation but add this note at the end:
💡 Tip: Run 'learn skills' later to understand the skill system deeply.
If learn_skills NOT in pending_onboarding: Proceed normally without suggestion.
Anti-Pattern Detection
If user is creating similar items (report-jan, report-feb, report-mar pattern):
💡 I notice you're creating similar items. This is a perfect use case for
a SKILL instead of multiple builds/files. Want to 'learn skills' first
to understand how to capture this as a reusable workflow?
Create Skill
This skill provides guidance for creating effective skills.
About Skills
Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.
What Skills Provide
- Specialized workflows - Multi-step procedures for specific domains
- Tool integrations - Instructions for working with specific file formats or APIs
- Domain expertise - Company-specific knowledge, schemas, business logic
- Bundled resources - Scripts, references, and assets for complex and repetitive tasks
Core Principles
What ships with it
11 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.

create-skill is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT. It adds 16 tokens to every session and 5,465 once invoked, about $0.0001 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 2026-09-03.
