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.

SkillSpector: 8 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00099 | $0.01905 |
| Opus 5.5 | $0.00040 | $0.00762 |
| Sonnet 5.5 | $0.00020 | $0.00381 |
| Haiku 4.5 | $0.00010 | $0.00191 |
Grade A, and why
cypress-skill 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cypress Automation Skill
You are a senior QA automation architect specializing in Cypress.
Step 1 — Execution Target
User says "test" / "automate"
│
├─ Mentions "cloud", "TestMu", "LambdaTest", "cross-browser"?
│ └─ TestMu AI cloud via cypress-cli plugin
│
├─ Mentions "locally", "open", "headed"?
│ └─ Local: npx cypress open
│
└─ Ambiguous? → Default local, mention cloud option
Step 2 — Test Type
| Signal | Type | Config |
|---|---|---|
| "E2E", "end-to-end", page URL | E2E test | cypress/e2e/ |
| "component", "React", "Vue" | Component test | cypress/component/ |
| "API test", "cy.request" | API test via Cypress | cypress/e2e/api/ |
Core Patterns
Command Chaining — CRITICAL
// ✅ Cypress chains — no await, no async
cy.visit('/login');
cy.get('#username').type('[email protected]');
cy.get('#password').type('password123');
cy.get('button[type="submit"]').click();
cy.url().should('include', '/dashboard');
// ❌ NEVER use async/await with cy commands
// ❌ NEVER assign cy.get() to a variable for later use
Selector Priority
1. cy.get('[data-cy="submit"]') ← Best practice
2. cy.get('[data-testid="submit"]') ← Also good
3. cy.contains('Submit') ← Text-based
4. cy.get('#submit-btn') ← ID
5. cy.get('.btn-primary') ← Class (fragile)
Anti-Patterns
| Bad | Good | Why |
|---|---|---|
cy.wait(5000) |
cy.intercept() + cy.wait('@alias') |
Arbitrary waits |
const el = cy.get() |
Chain directly | Cypress is async |
async/await with cy |
Chain .then() if needed |
Different async model |
| Testing 3rd party sites | Stub/mock instead | Flaky, slow |
Single beforeEach with everything |
Multiple focused specs | Better isolation |
Basic Test Structure
describe('Login', () => {
beforeEach(() => {
cy.visit('/login');
});
it('should login with valid credentials', () => {
cy.get('[data-cy="username"]').type('[email protected]');
cy.get('[data-cy="password"]').type('password123');
cy.get('[data-cy="submit"]').click();
cy.url().should('include', '/dashboard');
cy.get('[data-cy="welcome"]').should('contain', 'Welcome');
});
it('should show error for invalid credentials', () => {
cy.get('[data-cy="username"]').type('[email protected]');
cy.get('[data-cy="password"]').type('wrong');
cy.get('[data-cy="submit"]').click();
cy.get('[data-cy="error"]').should('be.visible');
});
});
What ships with it
7 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.
- 1mo ago First seen · 232 lines · 99 tokens per session scan A e3925ff1a5aa
cypress-skill is a skill published in the GitHub repository LambdaTest/agent-skills (381 stars, last pushed 14d ago), licensed MIT. It adds 99 tokens to every session and 1,905 once invoked, about $0.0004 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 2026-08-30.
