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 | $0.03813 | $0.03813 |
| Opus 5.5 | $0.01525 | $0.01525 |
| Sonnet 5.5 | $0.00763 | $0.00763 |
| Haiku 4.5 | $0.00381 | $0.00381 |
Grade A, and why
portfolio-v3 AGENTS.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 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Portfolio v3
Canonical instructions for any coding agent working in this repository (Cursor, Claude, Codex, Gemini, Copilot, and others). Platform files add tooling notes only. For UI, docs/ui/ is the source of truth and wins over every summary, this one included.
You are an expert full-stack TypeScript engineer. Produce production-ready code that follows modern Next.js App Router patterns and best practices.
Tech Stack
- Next.js 16 (App Router) + React 19
- TypeScript (strict mode)
- Styling: Tailwind CSS 3 (not v4) + shadcn/ui primitives restyled to the one-ink system
- Testing: Jest + React Testing Library (unit), Playwright (e2e)
- Package Manager: bun

Architectural Guidelines
- React Server Components (RSC): Default to Server Components. Add
'use client'only at the top of files requiring state, hooks, interactivity, or browser APIs. Keep client islands small. - Component Organization:
- Routes belong in
app/. - Reusable UI elements belong in
components/ui/. - Feature-specific code belongs in
components/[feature]/orapp/_components/.
- Routes belong in
- TypeScript: Use explicit
interfaceortypefor all props and state. Avoidany. - Styling:
- Use Tailwind utility classes and the tokens in
docs/ui/design-system.md. Shared CSS (.prose,.plate,.engraving,.ws, grain) lives insrc/app/globals.css. - Use
cn()from@/lib/utilsfor conditional class merging. - Mobile-first responsive design; no horizontal scroll at 375px.
- Use Tailwind utility classes and the tokens in
- Code Quality: Keep functions small. Abstract complex or repetitive logic into hooks or
lib/. No superfluous comments — names should be self-documenting. - Package manager: Use bun (
bun install,bun run,bunx). Never npm, pnpm or yarn.
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.
