Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
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 | $0.00126 | $0.02029 |
| Opus 5 | $0.00063 | $0.01014 |
| Sonnet 5 | $0.00025 | $0.00406 |
| Haiku 4.5 | $0.00013 | $0.00203 |
Grade A, and why
interaction-design-board scanned grade A 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Interaction Design Board
Turn interaction uncertainty into inspectable evidence. Keep the product's real facts and design language fixed; vary the interaction architecture enough that the user can experience the trade-offs before production code changes.
Route The Request
- Use this skill when the choice depends on behavior, state, workflow, hierarchy, or progressive disclosure.
- Use
design-style-pickerfor static visual-style calibration and image matrices. - Use gstack's
design-consultationfor a new product-wide design system and gstack'sdesign-shotgunfor static generated mockups. - Return to this skill after a visual direction is chosen if the user still needs to compare clickable interaction structures.
- Do not use it for a settled one-line CSS adjustment or when the user already supplied an approved interaction specification and asked only for implementation.
Non-Negotiable Outcome
Produce a decision, not a gallery:
- Several runnable HTML candidates keep the same business facts, product scope, design tokens, and available actions.
- Each candidate embodies a distinct interaction hypothesis rather than a skin.
- The Design Board lets the user operate every candidate, record concrete feedback, select one, or request a named remix.
- Production implementation does not start until the user approves the behavior.
Static screenshots are supporting evidence only. A screenshot cannot prove a collapse state, keyboard path, selection model, or task handoff.
Workflow
1. Freeze The Decision Contract
Before generating variants, write a compact contract in the session workspace:
- User job: the real task the operator is trying to complete.
- Decision scope: the one page, component, or bounded journey being compared.
- Immutable facts: real objects, labels, statuses, permissions, actions, and data semantics that every variant must preserve.
- Existing language: current tokens, components, navigation, density, and brand assets that must remain recognizable.
- First-view invariant: what must stay visible before any disclosure.
- Interaction states: the meaningful states the user must be able to exercise.
- Stop condition: approved variant or explicit remix brief; no product edit yet.

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.

interaction-design-board is a skill published in the GitHub repository daymade/claude-code-skills (1,381 stars, last pushed today), licensed MIT. It adds 126 tokens to every session and 2,029 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

prototype-web
A clickable, high-fidelity web product prototype with navigation, a hero section, feature cards, steps, social proof, and optional pricing. It is designed to resemble a finished landing page while remaining a prototype.
animation-principles
Apply animation principles — easing, staging, follow-through — to one specific UI motion. Use when tuning how an animation feels. For product-wide duration and easing tokens use motion-system (design-systems); for a full interaction spec use micro-interaction-spec.

Audit and fix visual hierarchy, spacing, color, and depth in web UIs. Use when the user mentions "my UI looks off" (or amateur/unprofessional), "fix the design", "Tailwind styling", "color palette", "visual hierarchy", "design system", "spacing scale", or "component styling". Also trigger when building consistent…
