Skill Codex
A testing guide for checking how an AI agent classifies failures and recovers from them. It focuses on retries, fallback actions, escalation, consistent state, user notices, and evidence that recovery happened.
Skill Codex
A testing guide for AI agents that run for a long time or may be interrupted. It covers checkpoints, periodic health signals, resuming work, cancellation, duplicate submissions, time limits, and resource cleanup.
Skill Codex
Use this skill when you need evidence-bounded loop state, plan/action/observation cycles, stop conditions, budgets, repetition, and trace evidence; triggers include Agent 循环 and Agent loop.
Skill Codex
Use this skill when you need evidence-bounded memory write/read/update/delete, retention, contamination, isolation, provenance, and forgetting behavior; triggers include Agent 记忆 and Agent memory.
Skill Codex
Use this skill when you need evidence-bounded Agent identity, tool/resource scope, approval, denial, escalation, and side-effect boundaries; triggers include Agent 权限 and Agent permission.
Skill Codex
Use this skill when you need evidence-bounded safety policy, abuse categories, refusal/redirect behavior, privacy, escalation, and Human risk decisions; triggers include AI 安全 and AI safety.
Skill Codex
An API error contract testing guide for checking error responses against documented agreements. It covers status codes, error formats, codes, and information disclosure.
Skill Codex
An API idempotency testing guide for checking what happens when the same request is retried or sent more than once. An idempotent operation produces the same intended result without repeating an unwanted side effect.
Skill Codex
An API negative testing guide for designing checks around invalid inputs and rejected requests. Negative testing asks how software behaves when something is wrong or unexpected.
Skill Codex
An API pagination testing guide for checking how an API splits an ordered set of results into pages. It covers cursor-based and offset-based paging when the relevant evidence is available.
Skill Codex
An API rate-limit testing guide for designing checks around quotas, request bursts, and recovery. A rate limit restricts how many requests a client can make in a period of time.
Skill Codex
Use this skill when you need to compare API schemas with sourced request and response evidence; triggers include API Schema 校验 and API schema validation.
Skill Codex
An API security testing guide for evidence-based security analysis and validation planning. APIs are interfaces that let software exchange data and actions.
Skill Codex
An API version compatibility testing guide for comparing old clients and new servers, or new clients and older servers, using version and deprecation evidence. Compatibility means that connected versions continue to work together.
Skill Codex
An authentication testing guide for analysing how an API verifies who a user or service is. Authentication establishes identity; it is separate from authorization, which checks permissions.
Skill Codex
An authorization testing guide for analysing whether users or services are allowed to perform particular actions. Authorization is the permission check that happens after an identity is established.
Skill Codex
An evidence-based analysis guide for deciding where test automation may be worthwhile. Test automation means using software to run checks instead of repeating them manually.
Skill Codex
A boundary-value test-design guide for selecting values at and near important limits. Boundary-value testing checks edges such as minimums, maximums, lengths, times, and resource limits.
Skill Codex
A chaos-testing analysis and validation guide for deliberately examining how systems behave under disruptive conditions. Chaos testing means introducing controlled failures to find weaknesses before real incidents do.
Skill Codex
A guide for analysing and preparing improvements to a CI test pipeline. CI, or continuous integration, automatically builds and tests code changes as they are submitted.
Skill Codex
A circuit-breaker testing analysis and validation guide. A circuit breaker is a software control that temporarily stops calls to a failing service.
Skill Codex
A combinatorial test-design guide for choosing high-risk combinations of several factors. It works after the factors, their possible values, and their constraints are clearly defined.
Skill Codex
A cross-browser test-coverage guide for selecting browsers, rendering engines, devices, and versions. A browser engine is the software that turns web code into a displayed page.
Skill Codex
A decision-table test-design guide for turning conditions, rules, actions, and outcomes into a traceable set of combinations. A decision table is a structured way to show what should happen for each rule.
