angular-tdd

angular-tdd is a skill for Claude Code, Codex from cuongtl1992/vibe-skills. It costs 112 tokens per session (1,842 once invoked), scanned A, original, MIT.

A test-first workflow for Angular features. Test-driven development, or TDD, means writing a failing test before implementing the code that should make it pass.

In plain words
What is it for?
Use it to build Angular features with Jest and TestBed, understand existing project conventions, and implement interfaces from Figma designs.
Why use it?
It provides a repeatable path from exploring an unfamiliar codebase through testing, implementation, cleanup, and review.

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.

Security

Grade A, and why

angular-tdd 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 8d 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.

Angular TDD Workflow

Test-Driven Development workflow for Angular applications using Jest + TestBed.

Every piece of code follows the Explore → Plan → Test (RED) → Implement (GREEN) → Refactor → Review cycle.


Phase 0: EXPLORE

Before writing any code, understand the project you are working in.

  1. Identify Angular version — standalone components or NgModule? Signal-based or RxJS?
  2. Understand project structure — Nx monorepo? Feature libs? Hexagonal layers?
  3. Find testing setup — Jest or Karma? TestBed patterns? Existing mock strategies?
  4. Review existing patterns — component style, state management, data fetching approach
  5. Check styling — SCSS, Tailwind, Angular Material, component-scoped vs global

Exploration Output Template

Angular Version: [version] ([standalone/NgModule])
Reactivity: [Signals / RxJS / hybrid]
Project Type: [Nx monorepo / standalone app]
Structure: [feature-based / layer-based / hexagonal]
Testing: [Jest / Karma] + [TestBed patterns]
Styling: [SCSS / Tailwind / Angular Material / CSS]
State: [Signals / NgRx / RxJS services / state service pattern]
API Layer: [HttpClient + interceptors / custom client]
Key Conventions: [list notable patterns]

For the full exploration checklist, consult references/exploration-checklist.md.


Phase 1: PLAN

Analyze the requirement before writing any code or test.

Step 1: Figma Design Check

If the task involves UI work, ask the user:

"Does this task have a Figma design? If yes, please share the Figma link so I can review the design specifications (layout, spacing, colors, typography, responsive breakpoints)."

When a Figma link is provided:

  • Identify all visual components needed
  • Note spacing, colors, typography tokens
  • Identify responsive breakpoints and variants
  • Map design components to Angular components

For detailed Figma analysis process, consult references/figma-workflow.md.

Step 2: Requirement Analysis

  1. Understand the requirement — what is the expected behavior?
  2. Identify components — which Angular components, services, use cases are needed?
  3. List test cases — happy path, edge cases, error states, loading states, empty states
  4. Define the public API — component inputs/outputs, service methods, return types

What ships with it

3 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.

angular-tdd is a skill published in the GitHub repository cuongtl1992/vibe-skills (10 stars, last pushed 5mo ago), licensed MIT. It adds 112 tokens to every session and 1,842 once invoked, about $0.0006 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 2026-08-31.
