ng-elemental: Skill for Cursor

.cursor/skills/ng-elemental-review/SKILL.md

ng-elemental-review is a skill for Cursor from AtulFalle/ng-elemental. It costs 128 tokens per session (1,177 once invoked), scanned A, original, MIT.

A review guide for NgElemental UI widgets, which are reusable interface components in an Angular design system. It focuses on how components own and communicate their state.

In plain words
What is it for?
Use it when reviewing or changing NgElemental widgets, especially selection, open or view state, hover previews, drafts, repeated widget instances, and show or hide behavior.
Why use it?
It helps prevent bugs caused by two components controlling the same value, copying parent state into children, or incorrectly synchronizing selections, panels, drafts, and hover states.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is AtulFalle/ng-elemental's own configuration. It tells Cursor how to work on ng-elemental itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ng-elemental configures →

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

ng-elemental-review 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 11d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

NgElemental component review

One owner per piece of state. Children emit events. They do not copy, invert, or reduce parent state.

Read this before adding inputs, effects, or a second instance of the same El* widget. Also follow ng-elemental-component.

Applies to every design-system piece: triggers, overlays, lists, panes, fields, compound parent/child controls, and anything added later.

State table (required)

Before coding or finishing a review, fill this for the widget in front of you. Any row with two owners is a defect. Omit rows that do not exist.

State Owner (exactly one) How others see it
Selected / checked / value Parent model() Inputs down
Visible window (open panel, active tab, step, page, section, stage) Parent, or local UI-only on the child Input down, Change event up
Hover / highlight / preview Parent if more than one pane or item paints it Input down, event up
Uncommitted drafts (typed fields, filter text, in-progress range) The draft UI Commit event up

Local UI-only state (which nested face is showing, which row is focused) may live on the child. Do not sync it back with an effect.

Review output

  1. State table (filled)
  2. Defects: Critical / Important / Minor
  3. Stop if Critical or Important state-ownership defects remain

Defects to reject

Flag-sliced god widget. showHeader + showBody + showFields (or any showX set) means the component is several widgets. Split: leaf pane vs fields vs overlay shell vs list vs item.

Stub instance. Mounting a widget with most of the UI hidden only to reuse a slice of logic. Duplicate the small template or extract a tiny sibling. Do not run a full grid, list, or effect brain just to host inputs.

Mirrored controlled state. Parent window plus child copy plus effect + untracked + *Change (including inverted math on a sibling). Parent owns the window; child receives it and emits Change.

Reducer in every child. Start/end/swap, next/prev, or toggle-set implemented in each instance. Children emit what happened (itemSelected, stepChange); the parent updates value once.

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.
