A beginner guide and project starter for building simple websites with HTML, CSS, JavaScript, or the Next.js web framework.

Use it to start a portfolio or static website, learn basic web concepts, get example code, and receive next-step guidance suited to a first project.

It removes the need for beginners to work out the project structure, basic setup, and first development steps on their own.

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.

Token cost

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	$0.00031	$0.01818
Opus 5.5	$0.00012	$0.00727
Sonnet 5.5	$0.00006	$0.00364
Haiku 4.5	$0.00003	$0.00182

Security

Grade A, and why

starter 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 28d 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.

Beginner (Starter) Skill

Actions

Action	Description	Example
`init`	Project initialization (/init-starter feature)	`/starter init my-portfolio`
`guide`	Display development guide	`/starter guide`
`help`	Beginner help	`/starter help`

init (Project Initialization)

Create project directory structure (HTML/CSS/JS or Next.js)
Generate package.json (when Next.js selected)
Create CLAUDE.md (Level: Starter specified)
Create docs/ folder structure (for PDCA documents)
Initialize the pipeline store — writeBkitMemory() in lib/pdca/status.js, which writes .bkit/state/memory.json (the migrated path of .bkit-memory.json). This holds the project level and the 9-phase pipelineStatus, read by the pipeline Stop hooks for phases 5, 6 and 9. It is NOT where the PDCA phase lives — that is .bkit/state/pdca-status.json.

guide (Development Guide)

Analyze current project state
Suggest next steps appropriate for Starter level
Phase 1-3 focused Pipeline guide

help (Beginner Help)

Explain HTML/CSS/JS basic concepts
Answer frequently asked questions
Provide example code

Target Audience

Those learning programming for the first time
Those who want to create a simple website
Those who need a portfolio site

Tech Stack

Option A: Pure HTML/CSS/JS (For Complete Beginners)

HTML5        → Web page structure
CSS3         → Styling
JavaScript   → Dynamic features (optional)

Option B: Next.js (Using Framework)

Next.js 14+  → React-based framework
Tailwind CSS → Utility CSS
TypeScript   → Type safety (optional)

Language Tier Guidance (v1.3.0)

Recommended: Tier 1 languages only (Python, TypeScript, JavaScript)

Starter level focuses on AI-Native development with maximum AI tool support.

Tier	Allowed	Reason
Tier 1	✅ Yes	Full AI support, Vibe Coding optimized
Tier 2	⚠️ Limited	Consider Dynamic level instead
Tier 3-4	❌ No	Upgrade to Dynamic/Enterprise

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.

This skill should be used when a user wants to scaffold or refactor a design token system — e.g. "set up design tokens", "create a design system foundation", "extract these hardcoded colors into tokens", "add a type scale", "theming setup", or "dark mode tokens". It produces a single source of truth for color, type…
