Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.07384 |
| Opus 5.5 | $0.00000 | $0.02954 |
| Sonnet 5.5 | $0.00000 | $0.01477 |
| Haiku 4.5 | $0.00000 | $0.00738 |
Grade A, and why
ui 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 1mo 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 — 843 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Personal Assistant UI Guidelines
Project Overview
The Personal Assistant UI is built with Angular and follows modern best practices for scalable frontend applications. It interfaces with the Personal Assistant API to provide a user-friendly interface for content creation and management.

Code Organization Guidelines
Component Structure
Components must be split into separate files for TypeScript, HTML, and SCSS:
component-name/
├── component-name.component.ts
├── component-name.component.html
├── component-name.component.scss
└── component-name.component.spec.ts
Component Definition
All components should be standalone and use the following structure:
import { Component, OnInit } from '@angular/core';
import { CommonModule } from '@angular/common';
@Component({
selector: 'app-example',
standalone: true,
imports: [CommonModule],
templateUrl: './example.component.html',
styleUrls: ['./example.component.scss']
})
export class ExampleComponent implements OnInit {
// Component properties
constructor() {}
ngOnInit(): void {
// Initialization logic
}
// Component methods
}
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.

ui is a cursor rule published in the GitHub repository theimaginaryfoundation/what-iff (19 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 7,384 tokens. 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 2026-09-09.
