cypress-testing

cypress-testing is a skill for Claude Code, Codex from monkilabs/opencastle. It costs 69 tokens per session (413 once invoked), scanned A, original, MIT.

A Cypress testing tool for browser-based end-to-end tests and component tests. End-to-end tests check a complete user flow, while component tests check an individual interface part.

In plain words
What is it for?
Use it to write and run tests, intercept network requests, reuse authenticated sessions, create custom commands, choose stable selectors, and store screenshots or videos for failed runs.
Why use it?
It helps make browser tests more reliable by handling network stubs, cached login sessions, selectors, and test failure files consistently.

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

cypress-testing 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (config.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Cypress Testing

Project test config and breakpoints: testing-config.md. Docs: https://docs.cypress.io

Layout

Specs cypress/e2e/ • fixtures cypress/fixtures/ • custom commands cypress/support/commands.ts • failure artifacts cypress/screenshots/ and cypress/videos/.

Gotchas

  • cy.session(key, setupFn) caches and restores auth state across specs — the cache key must include every credential that changes the session, or you will silently reuse the wrong user.
  • Give each spec unique @alias names for cy.intercept() routes. Shared alias names cause cross-test cy.wait() collisions when specs run in parallel.
  • Prefer cy.intercept() with fixed fixture payloads over seeding real data — it is the only reliable fix for network flake.
  • Selector priority: data-testidaria-* / role. Never auto-generated classes or deep CSS paths.
  • After npm install --save-dev cypress, run npx cypress verify — a corrupted binary cache fails later with confusing errors.

Commands

npx cypress open                                              # interactive
npx cypress run                                               # headless / CI, assert exit 0
npx cypress run --spec "cypress/e2e/auth/login.cy.ts" --headed # single-spec smoke check

On failure, re-run the failing spec alone and inspect the screenshot/video artifacts. In CI, upload those artifacts only on failure.

Files

What ships with it

1 file 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.
