What it does
Angular Performance is an agent skill from HoangNguyen0403/agent-skills-standard. Optimization techniques including OnPush, @defer, and Image Optimization. Use when optimizing Angular rendering, deferring blocks, or improving Core Web Vitals.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/defer-usage.md`).
It sits in Frontend & Design, covering Web performance. It works with Angular. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Optimizing Angular rendering
- Deferring blocks
- Improving Core Web Vitals
Example prompts
- “/angular-performance”
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Angular Performance loads about 595 tokens when it runs, and up to ~748 if it reads all its reference files. Until then it costs about 45 tokens; SKILL.md has 230 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Performance
Priority: P1 (HIGH)
Principles
- OnPush: Always use ChangeDetectionStrategy.OnPush on all components. Components should only update when Signals for state change or Inputs change.
- Deferrable Views: Use @defer (on viewport) to lazy load heavy components/chunks below fold. Use triggers: on interaction, on idle, when condition. @defer creates separate lazy-loaded chunk automatically. Use @placeholder {
<Spinner />} for loading states. - Images: Import NgOptimizedImage and replace
<img src='...'>with **<img ngSrc='...'** width='800' height='600'>. Add priority attribute for LCP images. This enables lazy loading, responsive srcset, and preconnect hints automatically.
Guidelines
- Zoneless: Prepare for Zoneless Angular by avoiding Zone.runOutsideAngular hacks. Use Signals for all reactive state instead. Opt into provideExperimentalZonelessChangeDetection().
- TrackBy: Always provide stable unique identifier in loops using @for (item of items; track item.id) — track expression replaces trackBy. This prevents Angular from destroying and recreating DOM nodes.
Anti-Patterns
- No function calls in template: {{ calculate() }} re-evaluates on every change detection cycle. Use computed() signal or pure pipes to avoid per-cycle re-evaluation as it caches until dependencies change.
- No logic in constructor: Initialize state in
ngOnInitor signal effects instead.
