A coding agent for building Angular 21 and TypeScript frontend features with Bootstrap 5.

Use it to create or modify Angular components, services, routes, forms, pagination, and other user-interface features in the CRM.

It applies the project's established structure and coding rules, reducing inconsistent components, forms, routing, and data handling.

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	$0.00034	$0.00649
Opus 5.5	$0.00014	$0.00260
Sonnet 5.5	$0.00007	$0.00130
Haiku 4.5	$0.00003	$0.00065

Security

Grade A, and why

fe-coder 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 1mo 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.

Specifications

Your spec reading list (paths are relative to the repo root):

Business domain (read first for domain context): docs/specs/DOMAIN.md
Primary (read first, before starting work): docs/specs/SPECS-frontend.md
Secondary (read only when the task needs it): docs/specs/SPECS-ui.md, docs/specs/SPECS-testing.md

Architecture Rules

Angular 21 standalone components — no NgModules, no standalone: true (it's the default)
Use imports: [...] in @Component for dependencies
Organize features in frontend/src/app/features/<entity>/
Each feature has: routes file, list, detail, and form components

Code Standards

DI: private service = inject(Service), not constructor injection
Control flow: @if/@for/@switch blocks only, never *ngIf/*ngFor
@for requires track
Reactive forms with FormBuilder
Edit mode via route param id, populate with patchValue()
Bootstrap 5 + SCSS for styling
@angular/localize/init must be imported in main.ts

Pagination

NgbPagination is 1-indexed, Spring Data is 0-indexed
Convert with this.currentPage - 1 in service calls

Models & Services

Separate interfaces: Firma (response) and FirmaCreate (input) in core/models/
One service per entity in core/services/, wrapping HttpClient calls to /api/<plural>

Key Locations

App routes: frontend/src/app/app.routes.ts (lazy-loaded)
App config: frontend/src/app/app.config.ts
Features: frontend/src/app/features/<entity>/
Models: frontend/src/app/core/models/
Services: frontend/src/app/core/services/
Proxy config: frontend/proxy.conf.json

Authorization

Routes guarded with canActivate: [permissionGuard('PERMISSION')]
Sidebar items need permission: 'PERMISSION'

Commands

Build: cd frontend && npx ng build
Dev server: cd frontend && npx ng serve --proxy-config proxy.conf.json

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.
