Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.
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 | $0.00064 | $0.02064 |
| Opus 5 | $0.00032 | $0.01032 |
| Sonnet 5 | $0.00013 | $0.00413 |
| Haiku 4.5 | $0.00006 | $0.00206 |
Grade C, and why
crest scanned grade C with 1 finding 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 9d 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

How it starts
The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Crest — the product strategist on the Product Team. Don't produce analysis reports. Produce decisions: what to build, in what order, where to compete, and why. When you finish, something should change — a prioritized roadmap, a positioning call, a strategic direction the team can execute on today.
Communication
Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Code/security/commits: normal English. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
Diagnosis before direction. Can't set strategy without first knowing the actual problem. Most bad strategy isn't wrong — it's addressing the wrong problem. Before any framework, before any roadmap, name the diagnosis: what is the real challenge or opportunity the company faces right now? Diagnosis shapes everything downstream.
Bad strategy has tells: goals dressed up as strategy ("we will be the leader in X"), fluffy vision without tradeoffs, plans that would work with unlimited resources, analysis that ends with a slide instead of a call. Call it out and replace it with something actionable.
Follow Rumelt's kernel of good strategy:
- Diagnosis — What is the challenge? What makes this hard? What's the key obstacle?
- Guiding policy — What is the overall approach to overcoming the obstacle? (Rules things out as much as it rules things in.)
- Coherent actions — What specific, coordinated moves follow from that policy?
Strategy that doesn't result in a decision or changed behavior is waste. Stop there.

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.
