skillless CLAUDE.md

skillless CLAUDE.md is an instructions file for coding agents from 5kahoisaac/skillless. It costs 598 tokens per session, scanned A, original, MIT.

A command-line tool for installing and managing AI-agent skills from categorised CSV lists. It can install or remove categories, list them, show help, and update itself.

In plain words
What is it for?
Use commands such as pack, unpack, list, help, and upgrade to manage skill collections, with a dry-run option to preview actions.
Why use it?
It avoids manually installing skills one by one and can target either global agent settings or the current project.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

skillless CLAUDE.md 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 5d 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.

skillless

A CLI tool for installing and managing AI agent skills from categorized CSV lists via npx skills.

What it does

  • skillless pack <category|all> — install all skills in a category
  • skillless unpack <category|all> — remove all skills in a category
  • skillless list — show available categories and skill counts
  • skillless upgrade — self-update to latest version
  • skillless help — show usage

Key commands

# Run the main tool
./skillless help

# Install skills from a category
./skillless pack python

# Install skills from a category locally (project-level)
skillless -s local pack python

# Dry-run (print commands without running)
skillless -n pack python

# List all categories
./skillless list

# Self-update
./skillless upgrade

Install for regular use

# 1. Clone this repo
git clone <repo-url>
cd skillless

# 2. Add a shell alias so `skillless` is available anywhere
chmod +x skillless
echo 'alias skillless="'"'$(pwd)'"'/skillless"' >> ~/.zshrc
source ~/.zshrc

# 3. Run globally by default
skillless pack python

Use -s local only when you want skills installed into the current project instead of your global agent config.

Project structure

  • skillless — main bash CLI entrypoint
  • lists/ — category CSV files (20 categories)
  • scripts/install-skills.sh — worker that processes CSV rows via npx skills add
  • skills-lock.json — lockfile tracking installed skill sources and hashes
  • README.md — project documentation
  • skillless.png — project logo

CSV format

Each .csv in lists/ has columns:

Column Description
repo GitHub repo (owner/repo)
skill_name Skill to install (empty = all from repo)
agents Target agents (opencode claude-code codex, or empty = auto-detect)

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.
