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 | $0.00018 | $0.00798 |
| Opus 5.5 | $0.00007 | $0.00319 |
| Sonnet 5.5 | $0.00004 | $0.00160 |
| Haiku 4.5 | $0.00002 | $0.00080 |
Grade A, and why
help 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 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.
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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Help Skill
This is the default skill loaded by the skill-to-mcp server when no skills directory is specified.
Purpose
The skill-to-mcp server converts AI Skills (following Claude Skills format) into MCP server resources. This help skill provides basic information about using the server.
Available Tools
The server provides three core tools:
- get_available_skills: Lists all available skills with their descriptions
- get_skill_details: Returns the full SKILL.md content and file listing for a specific skill
- get_skill_related_file: Reads any file within a skill directory
Installing Additional Skills
To use custom skills with this server, you need to:
- Create or obtain a skills directory containing skill subdirectories
- Configure the server to use your skills directory
Option 1: Using Command-Line Option
skill_to_mcp --skills-dir /path/to/your/skills
Or with uvx:
uvx skill_to_mcp --skills-dir /path/to/your/skills
Option 2: Using Environment Variable
Set the SKILLS_DIR environment variable:
export SKILLS_DIR=/path/to/your/skills
skill_to_mcp
Option 3: MCP Client Configuration
Configure your MCP client (e.g., Claude Desktop) to pass the skills directory:
{
"mcpServers": {
"my-skills": {
"command": "uvx",
"args": ["skill_to_mcp", "--skills-dir", "/path/to/your/skills"],
"env": {
"UV_PYTHON": "3.12"
}
}
}
}
Creating Your Own Skills
Each skill must:
- Have its own subdirectory
- Contain a
SKILL.mdfile with YAML frontmatter - Follow this frontmatter format:
---
name: my-skill-name
description: Brief description of what this skill does and when to use it
---

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.

help is a skill published in the GitHub repository biocontext-ai/skill-to-mcp (29 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 18 tokens to every session and 798 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
