Skill Codex
A guide for analysing tests of retry behaviour, such as what a service does after a temporary failure.
Skill Codex
A review guide for finding and checking where sensitive information, such as passwords or access keys, may be exposed.
Skill Codex
A guide for reviewing whether stated software requirements address security needs.
Skill Codex
A guide for examining how user sessions are protected during security testing. A session is the period in which a service recognises a user after sign-in.
Skill Codex
A guide for designing tests around changes between defined states. States describe conditions, while events, rules, and actions describe how a system moves between them.
Skill Codex
A guide for reviewing the quality of test code, including its checks, isolation, repeatability, setup data, and maintainability.
Skill Codex
A guide for judging how well test results indicate real defects or risks. It also considers missed defects and misleading signals.
Skill Codex
An analysis guide for the cost of maintaining tests, including change frequency, repair effort, flaky-test cost, ownership, maintainability, and confidence.
Skill Codex
An analysis guide for reducing test runtime using evidence about slow tests, profiling, setup and cleanup, parallel execution, isolation, and baselines.
Skill Codex
An analysis guide for test-suite health using runtime, flaky results, duplicate tests, quarantined tests, and maintenance evidence. A test suite is the collection of tests run for a project.
Skill Codex
An analysis guide for finding testing bottlenecks through queues, dependencies, team capacity, handoffs, and supporting evidence.
Skill Codex
A threat-modeling guide for analysing security risks and preparing validation work from available evidence. Threat modeling is the practice of identifying how a system could be attacked or misused.
Skill Codex
An analysis and preparation guide for testing timeouts, the limits placed on how long a test waits for an operation.
Skill Codex
A review guide for UI automation selectors, the rules tests use to find buttons, fields, and other interface elements.
Skill Codex
A guide for defining a UI test strategy across user journeys, interface states, platforms, and risks.
Skill Codex
A review guide for asynchronous waits in UI tests, including polling conditions and timeout evidence.
Skill Codex
A guide for planning visual regression tests, which compare a current interface with an earlier approved image to find unintended visual changes.
Skill Codex
Use this skill when designing, running, interpreting, or reporting Agent Skill evaluations, selecting cases or judges, and analyzing trigger, benchmark, or regression evidence; triggers include Skill evaluation and evaluation design.
Skill Codex
Use this skill when reviewing a complete Skill package for architecture, scope, triggers, independent installation, bilingual consistency, Eval readiness, and evidence boundaries; triggers include Skill quality review and package review.
Skill Codex
A short, visual test strategy that connects testing work to a project's goals and risks. It is intended to fit on one page.
Skill Claude CodeCodex
Offline answer fixtures for calibrating an experimental semantic judge; not a Pilot Skill or runtime result.
Skill Claude CodeCodex
Fixture only.
Skill Codex
Use this skill when you need to design functional test plans or cases for business flows, UI, data, and integrations; triggers include functional testing and functional test cases.
