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 | $0.00143 | $0.02376 |
| Opus 5 | $0.00072 | $0.01188 |
| Sonnet 5 | $0.00029 | $0.00475 |
| Haiku 4.5 | $0.00014 | $0.00238 |
Grade A, and why
site-customizer 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 4d 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 — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
site-customizer
Welcome to the front door of VibeCoding. Before your website exists, your brand needs to be defined — and this skill is where that magic happens.
Think of it like hiring a creative director. They're not building the website yet. They're learning everything about who you are, how you sound, what you look like, what you stand for. Then they brief every specialist on the team — the copy editor knows your voice, the designer knows your colors, the developer knows your tech preferences.
You're in good hands. Let's figure out your brand together.
Why This Skill Exists
Every other VibeCoding skill is a specialist:
- site-interviewer digs deeper into requirements
- site-generator builds the actual pages
- copy-editor polishes your words
- ux-reviewer checks usability
- seo-aeo-auditor optimizes for search
But here's the thing: they all need to know your brand to do their jobs well. Without you running this skill first, each specialist starts from scratch and makes assumptions that might not match your vision. The site-customizer ensures every skill on your team is aligned from day one.
Platform Compatibility
This system was designed for Claude Cowork (Anthropic's desktop tool for non-developers) but works equally well with:
- Manus (by Meta) — conversational, fast, with optional Google Nano Banana integration for on-brand image generation
- Claude Code — for developers who prefer the command line
- Any AI assistant that supports skills
Manus + Nano Banana Superpowers
If you're using Manus, your brand profile feeds directly into image generation. That means:
- Hero images, background photos, team illustrations, product visuals — all generated on-brand automatically
- No stock photo hunting, no brand mismatches
- Example: If your aesthetic is "warm, minimal, earth tones" and you run a yoga studio, Nano Banana generates images that look like they belong on your site
The Customization Interview
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.

site-customizer is a skill published in the GitHub repository mrhinkle/VibeCoding-a-Website (11 stars, last pushed 4mo ago), licensed MIT. It adds 143 tokens to every session and 2,376 once invoked, about $0.0007 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.
