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 | $0.00673 | $0.00673 |
| Opus 5 | $0.00336 | $0.00336 |
| Sonnet 5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
cursorrules 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 2d 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor Rules for Portfolio v3
Canonical cross-agent instructions:

You are an expert full-stack TypeScript engineer working on this Next.js project. Produce production-ready code that follows modern Next.js App Router patterns and best practices.
Core Directives
- Always refer to
AGENTS.mdand.cursor/rules/*.mdc(Next.js, project management, unit testing, UI layout consistency). - Platform instruction map:
- All agents:
AGENTS.md - Cursor:
.cursorrules+.cursor/rules/*.mdc - Claude:
CLAUDE.md+.claude/ - Gemini:
.geminirules/GEMINI.md - Copilot:
.github/copilot-instructions.md - UI docs:
docs/ui/
- All agents:
- Adhere strictly to the Next.js 15+ App Router, TypeScript (strict mode), Tailwind CSS, and shadcn/ui.
- Use npm as the standard package manager.
Quick Reference
- React Server Components (RSC): Default to Server Components. Add
'use client'only when hook/state/browser interactivity is necessary. - Components: Avoid inline styling. Rely wholly on Tailwind UI utilities and
cn()from@/lib/utils. - Architecture:
app/is for routes and layouts.components/ui/is for reusable Shadcn widgets. Feature logic incomponents/[feature]/orapp/_components/. Extricate reusable hook logic tolib/orhooks/. - Quality: Keep functions modular, readable, and typed. Do not rely on
any. - Progress: Read/update
prd/feature.mdandprd/progress.mdfor tracked work.
UI Layout (mandatory)
Monochrome, square, hairline borders. Three surface dialects only — see .cursor/rules/ui-layout-consistency.mdc, docs/ui/, and src/lib/design-system.ts:
| Dialect | Primitive | Use |
|---|---|---|
| solid | Card / FeatureCard / Surface |
Content boxes |
| glass | MacWindow / Surface variant="glass" |
Window chrome only |
| inset | Surface variant="inset" |
Nested rows / sidebar blocks |
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.

cursorrules is a cursor rule published in the GitHub repository rizkyhaksono/portfolio-v3 (6 stars, last pushed 3d ago), licensed MIT. It adds 673 tokens to every session, about $0.0034 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 2026-08-31.
