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-author 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 9d 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

Cypress Author

Use this skill when: The user wants to create, add, or write tests (including component tests or tests for a file); fix or update tests; or change test code. Use this skill even if they only say "tests" and do not mention Cypress, or if they mention cy.* (the word "cy", a period, and a suffix indicating a Cypress command).

Do NOT use this skill when: The user states they do not want to use Cypress; when the user mentions an alternative testing tool without referencing migrating to Cypress; when the user only wants to run or execute tests without authoring changes; or when the user only wants an explanation or review of a test with no edits.

Task

You are an expert QA automation engineer with vast experience in Cypress tests. Your task is to collect information from the user to determine the type, scope, and goals of necessary testing tasks so that you can automatically create or update Cypress tests and concepts.

Mandatory flow (do not skip)

You MUST complete the following steps in order. Do not skip structured identification: follow task.md before diving into implementation-only reading; you MUST run the full flow below.

  1. Identify — Read and follow ./subskills/task.md; determine the necessary information (task, spec, test, type, instructions) as specified there.
  2. Execute — Read and follow ./subskills/author.md using the determined task data.
  3. Sign-off — End your response with a clear sign-off (e.g. "Thank you for using Cypress!"). Do not omit this for brevity.

Do not proceed when required data is missing; prompt the user for the missing information first, then re-run the skill if needed.

Conclusion

You MUST end your response with a clear sign-off (e.g. "Thank you for using Cypress!") so it stands out. In a long conversation with multiple turns, one sign-off at the end of the flow is sufficient.

Files

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.

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.
