Claude Skills is a library of reusable capability packages that give Claude task-specific instructions, terminology, and output formats for building, launching, operating, and growing websites and brands. People working on branding, design, content, SEO, development, operations, growth, or research can use the skills across different website stacks. The catalogue contains selected skills and plugins from the library.
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 | $0.00141 | $0.02137 |
| Opus 5.5 | $0.00056 | $0.00855 |
| Sonnet 5.5 | $0.00028 | $0.00427 |
| Haiku 4.5 | $0.00014 | $0.00214 |
Grade A, and why
creative-brief-selector 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Creative Brief Selector
A starting-point selector for brand and microsite builds. Given a business spec (name, vertical, shape, one-line vibe, optional list of shipped demos), produces a creative brief grounded in three things:
- An archetype position from
brand-archetype-system, picked or composed to be deliberately distinct from the shipped demos. - A small set of live reference sites for that archetype-and-vertical combination, drawn from a curated bank plus optional per-build discovery.
- A divergence check against the shipped demos that flags palette, voice, structural pattern, and section-shape overlap before the brief is handed off.
The brief output is concrete tokens, not abstract families, including explicit section-shape choices (hero shape and footer shape) as first-class outputs alongside palette and voice. It is meant to be loaded by downstream build skills as the single creative artifact for the build.
When to use
- Starting any new brand or microsite build that should land in a specific aesthetic position.
- The first build in a portfolio (no prior builds to diverge from yet, but the divergence schema can be seeded for the next one).
- The second through nth build in a portfolio, where the risk of sibling output is real.
- After a portfolio audit that surfaced sibling builds: this skill is the systemic fix for the pattern.
- When a build's creative direction is being chosen between two adjacent archetypes and the call needs a reference-grounded reason.
When NOT to use
- The user wants pure aesthetic methodology guidance (use
creative-direction). - The user has a finished archetype and a finished brief and is asking for execution (skip to the downstream build skills).
- The user wants a logo or a finished identity (use
logo-design,brand-identity). - The user wants to define voice for an existing brand (use
brand-voice). - Defining brand strategy from zero positioning (use
brand-ideationfirst, then return to this skill).

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.

creative-brief-selector is a skill published in the GitHub repository rampstackco/claude-skills (1,001 stars, last pushed yesterday), licensed MIT. It adds 141 tokens to every session and 2,137 once invoked, about $0.0006 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 2026-08-30.
