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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.00770 |
| Opus 5 | $0.00040 | $0.00385 |
| Sonnet 5 | $0.00016 | $0.00154 |
| Haiku 4.5 | $0.00008 | $0.00077 |
Grade A, and why
shipwright-pipeline 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 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.
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

Shipwright Pipeline
Overview
Shipwright converts a plain-English app description into a fully built, tested, and deployment-ready application. It delegates execution to product-agent, an autonomous 9-phase build engine available on PyPI.
Prerequisites
- Python 3.10+ available in PATH.
product-agentinstalled (pip install product-agent).- Node.js 18+ for JavaScript/TypeScript stacks.
Supported Stacks
- Next.js + Supabase — Full-stack with auth, database, and edge functions
- Next.js + Prisma — Full-stack with type-safe ORM
- SvelteKit — Lightweight full-stack with Svelte
- Astro — Content-focused static and hybrid sites
Instructions
- Gather the app description from the user. Ask clarifying questions if the description is vague.
- Confirm the target stack. If none specified, recommend based on the app type:
- Data-heavy with auth: Next.js + Supabase
- API-first with complex models: Next.js + Prisma
- Lightweight interactive: SvelteKit
- Content or marketing site: Astro
- Run
product-agentwith the app description and selected stack. - Monitor the 9-phase pipeline: Intake, Architecture, Scaffold, Implement, Test, Integrate, Polish, Validate, Ship.
- Report results to the user including test summary and any warnings.
Output
- A complete, buildable project directory with all source code, tests, and configuration.
- A test report summarizing pass/fail counts.
- Build verification output confirming the project compiles and starts.
Error Handling
- If
product-agentis not installed, prompt the user to install it withpip install product-agent. - If a phase fails, report the phase name, error message, and suggested fix.
- If the selected stack is not supported, list available stacks and ask the user to choose.
Examples
Build a SaaS dashboard:
/shipwright-build Build a real-time analytics dashboard with user auth, team workspaces, and Stripe billing. Use Next.js + Supabase.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shipwright-pipeline is a skill published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,717 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 770 once invoked, about $0.0004 per session on Opus 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.
