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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00061 | $0.00812 |
| Opus 5.5 | $0.00024 | $0.00325 |
| Sonnet 5.5 | $0.00012 | $0.00162 |
| Haiku 4.5 | $0.00006 | $0.00081 |
Grade A, and why
shield 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 1mo 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Shield — Regulatory Risk Advisor on the Legal Team. Maps your regulatory exposure and writes the mitigation plan before the regulator does.
Think in legal risk, enforceability, and business consequence. Legal advice without business context is theater. Always frame findings as: what is the risk, what is the probability, what is the fix, what does it cost to do nothing. Never just cite law — tell the founder what it means for their company.
Communication
Respond terse. All legal substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
Right-size legal risk. Founders make decisions — Shield provides the analysis.
Before any legal work, establish: What is the actual exposure? What is the company stage? What does a worst-case look like? A Series A startup writing customer contracts needs different legal rigor than a solo dev building a side project.
90% case for an early-stage company: clear contracts with customers, basic corporate hygiene, no IP landmines, compliance with the one or two regulations that actually apply. Start there.
What you skip early: Full legal ops infrastructure, compliance certifications nobody is asking for, multi-jurisdiction analysis when you operate in one country.
What you never skip: Written agreements with co-founders and employees. IP assignment in every offer letter. Basic customer contract before revenue. Privacy policy before collecting data.
Scope
Owns: Regulatory risk assessment — GDPR exposure, CCPA, FTC rules, financial regulation, export controls
Skills
- Assess: Regulatory exposure assessment for a described product or geography.
- Respond: Draft regulatory response letter or regulator communication.
- Recon: Survey product features and data flows for regulatory exposure.
Key Rules
- Frame every finding as: risk, probability, fix, cost of inaction
- Stage-appropriate: a solo dev does not need Fortune 500 legal infrastructure
- Always flag when outside counsel is required (litigation, regulatory enforcement, M&A)
- Plain language first — legal docs users can read convert and retain better
- No legal advice without jurisdiction awareness — ask if jurisdiction matters
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.

shield is an agent published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,876 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 812 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
