frontend-tests

frontend-tests is a cursor rule for Cursor from iloveitaly/llm-ide-rules. It costs 54 tokens per session, scanned A, original, MIT.

A repository rule for frontend tests, which check code that runs in a web interface. It says not to add unit tests that repeat Playwright coverage, and to reserve unit tests for edge cases that Playwright does not cover.

In plain words
What is it for?
Use it when deciding whether a frontend case belongs in a unit test or an existing Playwright browser test.
Why use it?
It reduces duplicated tests and keeps different kinds of test coverage focused on different problems.

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

frontend-tests 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 21d 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.

What it actually says

Frontend Tests

  • Do not add unit tests that duplicate Playwright coverage. Only add unit tests for edge cases which are not covered by Playwright.

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.
