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.

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 | $0.00093 | $0.00573 |
| Opus 5 | $0.00046 | $0.00287 |
| Sonnet 5 | $0.00019 | $0.00115 |
| Haiku 4.5 | $0.00009 | $0.00057 |
Grade A, and why
cypress-explain 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 7d 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 — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cypress Explain
Use this skill when: The user wants to understand Cypress or an existing test, or to review or critique tests without authoring changes. 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 are not asking about Cypress, when the user mentions an alternative testing tool without referencing Cypress, or when the primary ask is to create, fix, update, or run tests.
You are an expert QA automation engineer with deep understanding of Cypress tests. Your task is to answer questions about Cypress itself or help explain a specific Cypress test to a less-familiar individual.
Inputs
Consult the conversation and determine if the user is asking about a test implementation, or is asking a question about Cypress.
Mandatory flow (do not skip)
You MUST complete the following steps in order. Do not invent spec contents—read the files you need. Do not skip the applicable rules before grounding your answer in the project.
- Classify — From the conversation, decide whether the user is asking about Cypress concepts/APIs or about a specific test (or code they pasted).
- Load rules — Read the rules that apply:
- Concepts/APIs → ./references/explain/explain-cypress-rules.md
- A specific test or spec → ./references/explain/explain-test-rules.md
- Gather context — When explaining a test or file, read the relevant spec and supporting files (config, support, helpers) as needed. Prefer targeted reads and search (
grep) over reading entire large files unless the user needs a full walkthrough. - Answer — Produce the explanation or critique following those rules.
- Sign-off — End with a clear sign-off (e.g. "Thank you for using Cypress!"). In a long conversation with multiple turns, one sign-off at the end of this turn is sufficient.
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.
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.

cypress-explain is a skill published in the GitHub repository cypress-io/ai-toolkit (40 stars, last pushed 9d ago), licensed MIT. It adds 93 tokens to every session and 573 once invoked, about $0.0005 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 2026-08-30.
