issues-ux

A set of user-interface rules for an Issues web application based on Nielsen’s usability heuristics, common guidelines for making interfaces understandable and predictable. It also requires reusing documented interface components from the project’s gallery.

In plain words
What is it for?
Review or change screens and user flows in the Issues application, including forms, notifications, ticket tracking, Kanban interactions, and dialogs.
Why use it?
It gives developers checks for loading feedback, navigation, consistency, error prevention, and other common usability problems. It reduces one-off interface patterns that users may find confusing.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

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.

Security

Grade A, and why

issues-ux 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.

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UI/UX — Nielsen heuristics

Every UI/UX change MUST be reviewed against Nielsen's 10 usability heuristics before merge.

Before creating or changing any UI element, read docs/ui-elements-gallery.md:

  1. Find an existing element to reuse (class, Material component, behavior).
  2. Match documented properties, style (tokens/classes), and behavior.
  3. If no element fits, add the new element to the gallery in the same PR.
  4. Do not introduce ad-hoc buttons, colors, or form patterns outside the gallery.

Checklist (per screen or flow)

# Heuristic Issues application
1 Visibility of system status Loading/disabled during submit; notification badge; kanban drop feedback; toasts
2 Match system / real world Domain terms from domain-specification.md; PT-BR labels; familiar tracker patterns (Kanban, ticket ID)
3 User control & freedom Cancel/close on dialogs; back navigation; logout; avoid disableClose unless required
4 Consistency & standards Gallery elements + styles.scss; same button hierarchy; no one-off hex colours
5 Error prevention mat-form-field validation; confirm destructive actions
6 Recognition over recall Visible nav, status filter, project cards — minimise memory load
7 Flexibility & efficiency Header search; Enter on search; role-based menu shortcuts
8 Aesthetic & minimalist Flat UI principles below; content over decoration; clear hierarchy
9 Error recovery .error messages; toasts; empty states with next-step guidance
10 Help & documentation Footer OpenAPI link; empty states; tooltips where labels are ambiguous

Flat UI design language

Issues follows flat UI design — the style popularized by Microsoft's Metro design language (Windows Phone, 2010) and continued in Microsoft Fluent Design. Flat design favours clarity and function over ornamental depth; it is the baseline for enterprise and productivity apps.

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.

issues-ux is a cursor rule published in the GitHub repository vepo/issues (8 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,279 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 2026-08-31.
