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	$0.00583	$0.00583
Opus 5.5	$0.00233	$0.00233
Sonnet 5.5	$0.00117	$0.00117
Haiku 4.5	$0.00058	$0.00058

Security

Grade A, and why

gaochangw.github.io CLAUDE.md 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 2mo 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.

Project Overview

This is a modern, minimalist portfolio template built with Astro and Tailwind CSS v4. It's designed to be easily customizable through a single configuration file while maintaining a clean, professional appearance.

Tech Stack

Astro: Static site generator
Tailwind CSS v4: Utility-first CSS framework using the new @tailwindcss/vite plugin
TypeScript: For type-safe configuration
Tabler Icons: Icon library

Development Commands

npm run dev       # Start development server
npm run build     # Build for production
npm run preview   # Preview production build

Architecture

The project follows a component-based architecture with all customization centralized in src/config.ts:

Components (src/components/): Individual Astro components for each section (Hero, About, Projects, Experience, Education, Header, Footer)
Main Layout (src/pages/index.astro): Single-page layout that imports all components
Configuration (src/config.ts): Single source of truth for all content and customization

Key Architectural Decisions

Single Configuration File: All content is managed through src/config.ts to make customization simple
Conditional Rendering: Sections automatically hide if their data is removed from the config
Component Independence: Each section is a self-contained component that reads from the config
Accent Color System: Single accentColor in config propagates throughout the site via CSS custom properties

Important Implementation Details

The site uses Tailwind CSS v4 with the Vite plugin configuration
No linting or testing framework is currently configured
All components are in .astro format (not React/Vue/etc)
The project uses IBM Plex Mono font loaded from Google Fonts
Social links in the config are all optional and will conditionally render

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.
