A style rule set for naming SCSS classes with BEM, a convention that groups names into a component, its parts, and its variations. It applies these rules to NgElemental UI and documentation styles.

Use it when writing or reviewing Angular component and documentation styles, including names such as blocks, elements, and modifiers for UI parts and their states.

It keeps related styles easy to identify and reduces collisions caused by generic names such as “active” or “open.” It also sets conventions for component prefixes, separate SCSS files, and limited use of deep styling.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/AtulFalle/ng-elemental

Made for: Cursor.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00384
Opus 5	$0.00000	$0.00192
Sonnet 5	$0.00000	$0.00077
Haiku 4.5	$0.00000	$0.00038

Security

Grade A, and why

bem-scss 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 today.

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.

What it actually says

BEM SCSS

Use Block Element Modifier naming for all component and docs styles.

Pattern

Block: .el-button, .docs-example, .docs-page
Element: .el-button__label, .docs-example__canvas, .docs-page__header
Modifier: .el-button--primary, .docs-example--code, .docs-toc__link--active

Rules

Do not use bare state classes like .is-active, .active, .open on their own. Prefer a modifier on the block or element: .docs-toc__link--active.
Do not invent one-off utility class names outside an existing block (e.g. .docs-section-lead). Nest under the block: .docs-page__section-lead.
Prefer styleUrl + a sibling .scss file over large inline styles: strings for new docs/UI chrome.
Library widgets use the el- prefix: .el-<block>, .el-<block>__<element>, .el-<block>--<modifier>.
Docs app chrome uses the docs- prefix the same way.
Avoid styling through ::ng-deep when possible. If a docs demo must pierce encapsulation (e.g. rounded button), keep the piercing rule under a clear BEM block such as .docs-page__rounded.

Examples

/* Good */
.docs-example__toolbar { }
.docs-toc__link--active { }
.el-button--ghost { }

/* Bad */
.is-active { }
.docs-section-lead { }
.view-code-btn { }

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.
