What is angular-forms?

Guidance for building typed Angular reactive forms with controls whose values are checked by TypeScript, plus reusable validation functions.

Use it when creating complex forms, defining strictly typed fields, adding custom validation rules, or synchronizing form changes with application state.

It helps catch incorrect form data in code and avoids unexpected null values and validation logic scattered through components.

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.

Any agent

npx skills add HoangNguyen0403/agent-skills-standard --skill angular-forms

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	$0.00039	$0.00367
Opus 5	$0.00019	$0.00183
Sonnet 5	$0.00008	$0.00073
Haiku 4.5	$0.00004	$0.00037

Security

Grade A, and why

angular-forms 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 7d 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.

What it actually says

Forms

Priority: P2 (MEDIUM)

1. Use Strictly Typed Reactive Forms

Prefer Reactive Forms to Template-Driven for complex inputs.
Define typed FormGroup<T> with explicit control types — never use untyped FormGroup.

See typed forms for typed FormGroup examples.

2. Extract Validation Logic

Create standalone validator functions in separate file.
Name the validator module as a separate file (for example, validators.ts) in the response and keep validation out of the component class.
Sync valueChanges to stores using takeUntilDestroyed().

See typed forms for standalone validator examples.

3. Ensure NonNullable Controls

Use fb.nonNullable.group(...) or nonNullable: true on individual controls.
This ensures form values always strings — avoids null in form values.

Anti-Patterns

No Template-Driven Forms: Use Reactive Forms for any non-trivial inputs.
No untyped FormGroup: Always use strictly typed FormGroup<T>.
No validation in component: Extract into standalone validator functions.

Files

What ships with it

2 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.

Changes

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.
