- Works in 3 steps: Skill Structure → SKILL.md Format Requirements → Generation Guide

What it does
Skill Generator is an agent skill from MatrixAges/polywise. Called when users need to create new OpenCode skills. Automatically creates directory structure and writes SKILL.md files conforming to specifications.
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: The open source agentic content system to make your contents alive. Self-hosted on any platform. ◑. The licence is MIT.
When your agent uses it
- Tasks that involve Skill authoring
Example prompts
- “/skill-generator”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit f8d2320. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Generator loads about 333 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 137 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md

Skill Generator
This skill is used to extend new specialized skills for AI in the project, ensuring new skill files meet the project's format requirements.
1. Skill Structure
Each new skill must be placed in the .opencode/skills/{skill-name}/ directory, and its main file must be named SKILL.md.
2. SKILL.md Format Requirements
YAML Frontmatter description must be included at the top of the file, containing the following two fields:
---
name: { skill-name }
description: { A piece of English or Chinese text describing when and what the skill does }
---3. Generation Guide
- Create Directory: Create a new skill-named folder under
.opencode/skills/. - Write Content: Use Markdown syntax to detail the following under the skill:
- Core architecture/principles
- Naming and code style specifications
- Specific execution best practices
- Mandatory red lines (what absolutely cannot be done)
- Language Alignment: New skill content should尽量 use Chinese (to align with unified specifications), but the YAML header
namemust be English letters and hyphens.
