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.

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 | $0.00066 | $0.00944 |
| Opus 5 | $0.00033 | $0.00472 |
| Sonnet 5 | $0.00013 | $0.00189 |
| Haiku 4.5 | $0.00007 | $0.00094 |
Grade A, and why
angular-ui-patterns 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 6d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Iron Law
LOAD angular-spa FIRST for daisyUI component classes and TailwindCSS 4.x tokens. This skill provides UI state doctrine — use angular-spa reference files for the actual component HTML/CSS.
When to Use This Skill
Load this skill when:
- Building any Angular component that fetches async data
- Adding loading, error, or empty states to a list or page
- Implementing form validation with inline field errors
- Adding button loading states or disabling during async operations
- Building confirmation dialogs or modals
- Reviewing a component for missing UI state coverage
Five Non-Negotiable Principles
- Never show stale UI — Loading states only when actually loading, never over existing data
- Always surface errors — Users must know when something fails; never swallow silently
- Optimistic updates — Make the UI feel instant; roll back on failure
- Progressive disclosure — Use
@deferto show content as available - Graceful degradation — Partial data is better than no data

| reference/error-handling.md | Adding error handling |

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

angular-ui-patterns is a skill published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 66 tokens to every session and 944 once invoked, about $0.0003 per session on Opus 5. 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 2026-09-03.
