What is primeng-developer?

A skill for building Angular interfaces with PrimeNG, a component library for Angular applications. It covers PrimeNG components, themes, design tokens, styling modes, and customization APIs across supported versions.

Use it when installing, theming, customizing, migrating, or writing PrimeNG components in Angular projects, especially projects using PrimeNG 18 through 22.

It helps developers choose the correct PrimeNG APIs and avoid version-specific mistakes in components, themes, and migrations.

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	$0.00171	$0.02385
Opus 5.5	$0.00068	$0.00954
Sonnet 5.5	$0.00034	$0.00477
Haiku 4.5	$0.00017	$0.00238

Security

Grade A, and why

primeng-developer 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 10d 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.

PrimeNG Developer Guidelines

Pairs with angular-developer - that skill provides Angular fundamentals (signals, DI, routing, forms, SSR, accessibility). This skill focuses on PrimeNG specifics. Install both for the best experience.

Compatibility

Tracks: PrimeNG 22.1.3 (released 2026-10-20), with @primeuix/themes and @primeuix/styles both 3.x (currently 3.0.2). PrimeNG follows Angular's major, so v22 requires Angular v22 (peer @angular/core@^22.1.0 from 22.1 on, ^22.0.0 on 22.0.x).
Works for: PrimeNG v18 → v22 projects. The skill references include migration.md covering the v18 component renames (Calendar→DatePicker, Dropdown→Select, etc.) and the v21→v22 removals, so v18-v21 projects can use this skill but expect drift on theming and a few component APIs. v22 is the closest match.
v21 → v22: v22 is an Angular-22 alignment plus @primeuix/themes/@primeuix/styles v3, and it finalizes (removes) the APIs that were deprecated "for removal in v22" in earlier versions, @primeng/themes import path, pTemplate, styleClass, showTransitionOptions/hideTransitionOptions, camelCase selectors, and the pButton icon/label props among them. Treat those as gone, not merely deprecated. See migration.md.
v22.0 → v22.1: no breaking changes. 22.1 adds the experimental withIsolation() feature (primeng/isolation) for micro frontends and embedded widgets, filterMessage / selectionMessage / emptySelectionMessage inputs on p-select, a filteredNodes model on p-tree, and raises the Angular peer to ^22.1.0. Also remember v22 sizes components for a 16px root font; apps still on a 14px root should use the -compat presets (see theming.md). See migration.md.
Docs domain: the official docs moved from primeng.org to primeng.dev (old links 301-redirect).
Angular: v18 or newer required (v22 for PrimeNG v22). PrimeNG components are standalone since v18. The skill assumes standalone components, control flow (@if / @for), and signal-based APIs.
Tailwind: v3 or v4 with tailwindcss-primeui plugin (optional, for unstyled mode).
Not supported: PrimeNG v17 and below (different theming model based on prime.css), Angular v17 or below (NgModule patterns).

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.
