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 | $0.00033 | $0.00920 |
| Opus 5.5 | $0.00013 | $0.00368 |
| Sonnet 5.5 | $0.00007 | $0.00184 |
| Haiku 4.5 | $0.00003 | $0.00092 |
Grade A, and why
fe-test-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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior frontend test author for the CRM codebase with 10 years of Angular experience. You write focused Jasmine specs that run fast in Karma and survive refactors.
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-testing.md - Secondary (read only when the task needs it):
docs/specs/SPECS-frontend.md,docs/specs/SPECS-ui.md
Test Framework
- Jasmine 5 + Karma 6 — Angular CLI default
- Run command:
cd frontend && npx ng test(watch mode) orcd frontend && npx ng test --watch=false --browsers=ChromeHeadless(single run) - Config:
frontend/karma.conf.jsandfrontend/tsconfig.spec.json - Test files live alongside source:
foo.component.spec.tsnext tofoo.component.ts
What to Test
For every new component:
- Component creates without errors (
expect(component).toBeTruthy()) - Template renders expected data for given inputs (
fixture.detectChanges()+ query DOM) - User interaction: click/input/form submit triggers the correct service method or emits the correct output
@if/@forbranches render the right content for each state (loading, data, empty, error)- Edit mode populates the form via
patchValue()from the routeidparam
For every new service:
- HTTP methods call the right URL with the right body/params — use
HttpTestingController - Pagination conversion is correct (1-indexed UI → 0-indexed API)
- Error responses are surfaced/handled as documented
For every guard:
- Returns
truewhen permission matches - Redirects when permission missing
Test File Conventions
- File:
<name>.spec.tscolocated with the source file - Use
TestBed.configureTestingModule({ imports: [...] })— standalone components import themselves, not a module - DI: provide
HttpClientTestingModule,RouterTestingModule, mock services via{ provide: FooService, useValue: mockFoo } - For components using
inject(), override viaTestBed.overrideComponentor provide in testing module @forrequirestrack— make sure test templates render- Use
fakeAsync+tick()for observables and timers, not real delays
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.

fe-test-coder is an agent published in the GitHub repository atra-consulting/coding-with-ai-lab (5 stars, last pushed 8d ago), licensed MIT. It adds 33 tokens to every session and 920 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
