What it does
Skills Factory is an agent skill from aiskillstore/marketplace. Meta-skill for creating production-ready Claude Code skills using evaluation-driven development, progressive disclosure patterns, comprehensive validation, and two-Claude iterative methodology
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts and reference files (for example `references/DEPLOYMENT_GUIDE.md`, `references/EVALUATION_GUIDE.md` and `references/TROUBLESHOOTING.md`).
The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
Example prompts
- “/skills-factory”
Requirements
- Python 3
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Understanding the Domain
- Planning Your Architecture
- Initialize Skill Structure
- Design & Implement
- Validate & Package
- Iterate Using Two-Claude Methodology
- Deploy & Distribute
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. 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
Ships 4 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythongitbash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Skills Factory loads about 3.2k tokens when it runs, and up to ~28k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 1,156 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,156 words (~3,183 tokens).
“A comprehensive meta-skill for creating, validating, and iterating on production-ready Claude Code skills.”
