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 | $0.00598 | $0.00598 |
| Opus 5 | $0.00299 | $0.00299 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
skillless CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
skillless
A CLI tool for installing and managing AI agent skills from categorized CSV lists via npx skills.
What it does
skillless pack <category|all>— install all skills in a categoryskillless unpack <category|all>— remove all skills in a categoryskillless list— show available categories and skill countsskillless upgrade— self-update to latest versionskillless help— show usage
Key commands
# Run the main tool
./skillless help
# Install skills from a category
./skillless pack python
# Install skills from a category locally (project-level)
skillless -s local pack python
# Dry-run (print commands without running)
skillless -n pack python
# List all categories
./skillless list
# Self-update
./skillless upgrade
Install for regular use
# 1. Clone this repo
git clone <repo-url>
cd skillless
# 2. Add a shell alias so `skillless` is available anywhere
chmod +x skillless
echo 'alias skillless="'"'$(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.

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.
