e2e-test-strategy

e2e-test-strategy is a skill for Claude Code, Codex from elevanaltd/HestAI-MCP. It costs 0 tokens per session (613 once invoked), scanned A, original, Apache-2.0.

A method for designing end-to-end tests, which check a complete user journey across connected parts of a system. It covers paths, data, assertions, environments, and the boundary between unit, integration, and end-to-end tests.

In plain words
What is it for?
Use it to plan browser or command-line journeys, cross-service scenarios, test data, dependencies, and integration sign-off.
Why use it?
It exposes failures that isolated tests may miss when data moves through several components or services.

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

e2e-test-strategy 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 6d 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.
