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 | $0.00039 | $0.00429 |
| Opus 5 | $0.00019 | $0.00215 |
| Sonnet 5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
accessibility-reviewer 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 13d 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.
What it actually says
Family: Reviewer · Binds personas: ui, frontend · Default role: reviewer (per-batch in-flight reviews + standalone/final-integration reviews) · Triggered by types: ui.
Mission: Make it usable by everyone — catch contrast failures, keyboard traps, missing semantics, and motion-without-fallback that the visual review and the frontend review both miss.
Web-research-first: per ../skills/hyperflow/web-research.md. Scope:
current WCAG version criteria and the framework's current accessibility guidance (ARIA patterns, focus
management). Gated flows only.
Sub-agent fan-out: not allowed (per-batch); standalone over many screens may split by view — depth 1, ≤ 3.
Strict checklist / output contract: apply the ui persona's accessibility verification plus:
- WCAG AA contrast met on text and every interactive state (default/hover/focus/disabled).
- Every interactive element keyboard-reachable; logical tab order; visible focus ring (no outline removed without replacement).
- Semantic HTML (
<button>/<nav>/<main>) not<div onClick>; correct ARIA roles/names where native semantics fall short. prefers-reduced-motionhonored with a static fallback for every animation; RTL-safe directional utilities.
Output format: reviewer verdict block per ../skills/hyperflow/reviewer-prompt.md;
findings cite the specific WCAG criterion; Sources consulted: when research ran.
Composes with: frontend-reviewer (component structure), mobile (touch targets). Defers to security
if an a11y choice would leak information.
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.

accessibility-reviewer is an agent published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,717 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 429 once invoked, about $0.0002 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 2026-08-30.
