What it does
Skill Creator is an agent skill from gooseworks-ai/goose-skills. Create, structure, and package agent skills. Use when designing new skills, updating existing skills, or helping users build skills with scripts, references, and assets. Triggers on requests to create skills, write SKILL.md files, or structure skill directories.
Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.meta.json`).
It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: Library of Growth & GTM skills + data APIs for Claude Code, Codex, Cursor to run ads, social, content, lead gen, seo and data scraping. The licence is MIT.
When your agent uses it
- Designing new skills
- Updating existing skills
- Helping users build skills with scripts
- Requests to create skills
Example prompts
- “/skill-creator”
Requirements
- Python 3
- Node.js
- A credential in GOOSEWORKS_API_KEY
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Understand - Gather concrete usage examples
- Plan - Identify reusable scripts, references, assets
- Initialize - Run orth skills init
- Implement - Write SKILL.md, add resources
- Submit - Run orth skills submit
- Iterate - Test on real tasks, refine
What it can do on your machine
Read from SKILL.md and the folder at commit c650c6d. 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
Shell commands in SKILL.md call:
python3npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.gooseworks.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GOOSEWORKS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Creator loads about 893 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 240 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 Creator
Setup
Read your credentials from ~/.gooseworks/credentials.json:
export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login
All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"
Create modular, self-contained skill packages that extend agent capabilities.
Core Principle: Concise is Key
The context window is shared. Only add what the agent doesn't already know. Challenge every paragraph: "Does this justify its token cost?" Prefer concise examples over verbose explanations.

Degrees of Freedom
Match specificity to task fragility:

| High | Multiple valid approaches | Text instructions |
| Medium | Preferred pattern exists | Pseudocode, parameterized scripts |
| Low | Fragile/error-prone ops | Specific scripts, few params |
Creation Process
- Understand - Gather concrete usage examples

- Initialize - Run
orth skills init <name> - Implement - Write SKILL.md, add resources
- Submit - Run
orth skills submit <path> - Iterate - Test on real tasks, refine
Quick Start
# Create new skill
orth skills init my-skill
# Or with path
orth skills init my-skill --path ~/.openclaw/skills
# Submit to Orthogonal
orth skills submit ./my-skill
# Update existing skill
orth skills update <slug> ./my-skillWhat NOT to Include
- README.md, CHANGELOG.md, INSTALLATION_GUIDE.md
- Setup/testing procedures
- User-facing documentation
- Anything not needed for the agent to do the job
Progressive Disclosure
Keep SKILL.md under 500 lines. Split into reference files when approaching this limit.
