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 | $0.00159 | $0.04261 |
| Opus 5 | $0.00079 | $0.02131 |
| Sonnet 5 | $0.00032 | $0.00852 |
| Haiku 4.5 | $0.00016 | $0.00426 |
Grade A, and why
skill-creator 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 9d 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.
This is a copy
91% identical to skill-creator — 141 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Creator
This skill provides guidance for creating effective skills.
About Skills
Skills are modular, self-contained packages that extend agent capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform a general-purpose agent into a specialized agent equipped with procedural knowledge and domain expertise.
Skill Location for Deepagents
The deepagents CLI loads skills from five sources, listed here from lowest to highest precedence:
| # | Directory | Scope | Notes |
|---|---|---|---|
| 0 | <package>/built_in_skills/ |
Built-in | Ships with deepagents CLI |
| 1 | ~/.deepagents/<agent>/skills/ |
User (deepagents alias) | Default for deepagents skills create |
| 2 | ~/.agents/skills/ |
User | Shared across agent tools |
| 3 | .deepagents/skills/ |
Project (deepagents alias) | Default for deepagents skills create --project |
| 4 | .agents/skills/ |
Project | Shared across agent tools |
<agent> is the agent configuration name (default: agent). When two directories contain a skill with the same name, the higher-precedence version wins — project skills override user skills, and any user or project skill overrides built-in skills.
Example directory layout:
~/.deepagents/agent/skills/ # user skills (lowest precedence)
├── skill-name-1/
│ └── SKILL.md
└── ...
<project-root>/.deepagents/skills/ # project skills (higher precedence)
├── skill-name-2/
│ └── SKILL.md
└── ...
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
Concise is Key
The context window is a public good. Skills share the context window with everything else the agent needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
What ships with it
2 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.

skill-creator is a skill published in the GitHub repository Illuminated2020/DeepAgents-AutoGLM (120 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 159 tokens to every session and 4,261 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to skill-creator, differing in 141 lines, and is treated as a copy.
