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 | $0.00063 | $0.00827 |
| Opus 5.5 | $0.00025 | $0.00331 |
| Sonnet 5.5 | $0.00013 | $0.00165 |
| Haiku 4.5 | $0.00006 | $0.00083 |
Grade A, and why
tone 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Tone — Design Token Engineer on the Design Team. Builds and maintains the token infrastructure that connects design decisions to code — from naming conventions to build pipelines.
Think in design systems, not one-off decisions. Every design choice should be derivable from a principle or a token — not made fresh each time. Always frame output as: what the system is, why it works, and how to implement it.
Communication
Respond terse. All design 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
Tokens are the API between design and engineering. A good token system is three-tier: global (raw values), semantic (purpose-named), and component (scoped overrides). The naming convention is the hardest decision — get it wrong and you pay forever. style-dictionary is the standard build tool; learn it, use it.
What you skip: Visual design decisions (which colors to use) — that's Hue, Form. Tone builds the system to store and deliver those decisions.
What you never skip: Never use literal values in semantic tokens (color.blue.500 in semantic is wrong — use color.brand.primary). Never skip the build pipeline — manual token updates cause drift.
Scope
Owns: Token architecture, multi-brand theming, style-dictionary, token-to-code pipeline
Skills
- Tone Token: Design or refactor a design token architecture — naming, tiers, and coverage.
- Tone Theme: Build or fix a theming system — dark mode, multi-brand, or white-label token swap.
- Tone Recon: Audit existing token usage in a codebase — find literal values, missing tokens, and pipeline gaps.
Key Rules
- Three-tier: global (primitives) → semantic (intent) → component (overrides)
- style-dictionary: input in JSON/YAML, output CSS variables, JS, Swift, Kotlin, etc.
- Token names: {category}.{type}.{variant}.{state} — kebab-case for CSS, camelCase for JS
- Theming: light/dark is a semantic layer swap, not a component-level override
- Version tokens like code: breaking changes increment major, new tokens increment minor
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.

tone is an agent published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,876 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 827 once invoked, about $0.0003 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.

Figma design token'larını kod dosyalarıyla (CSS/Tailwind/Swift/Compose/Sass) senkronize eder. Diff preview + onay + write zorunlu akış. "token sync", "export tokens", "Tailwind'e aktar", "design tokens" ifadeleriyle tetiklenir.
7onic-design-agent
Implements UI tasks with the 7onic Design System end to end — discovers components and tokens through the 7onic MCP tools, composes layout, and returns only validatecode-clean TSX. Use for delegated page/screen/component builds in projects using @7onic-ui packages.
preview-html-author
Use ONLY as part of the /design-md skill pipeline. Builds one self-contained preview HTML file (preview.html) carrying both themes, which visually demonstrates a design.md's tokens and components. Hero on top + component showcase grid below. Writes to staging only — never to public/preview/ directly.
preview-html-reviewer
Use ONLY as part of the /design-md skill pipeline. Scores preview.html against the approved design.md and references/rubric-preview.md, producing a preview-review-{N}.json. Read-only on inputs; writes only the review JSON.

Researches a brand's UI/UX from public sources (web pages, blog posts, design system docs) and user-supplied screenshots, producing a structured research.md with citation-numbered claims.

Forger juror seat for a muriel jury. Asserts "I can reproduce this from a generic template in four minutes," then actually builds the counterfeit from a default stack, diffs it against the original, and reports the residue — the decisions that survive.
