Skill Claude CodeCodex
A skill for specifying a new feature in an existing product by checking the current code and documentation, then writing a requirements document with numbered requirements and acceptance conditions.
Skill Claude CodeCodex
A guided workflow for defining a software product and writing its specification. It covers concept development, research into similar products, a review checkpoint, and drafting the specification.
Agent
A product research agent that investigates competing and similar products, as well as alternative ways people solve the same problem.

ISTQB/JSTQB テストプロセススキル群（test-plan / test-monitor / test-analyze / test-design / test-implement / test-execute / test-report / test-review）。.
Skill Claude CodeCodex
A test-analysis skill that examines specifications, designs, code, and risks to identify what should be tested. It records these test conditions in a test-analysis.md file, but does not design individual test cases.
Skill Claude CodeCodex
A test-design guide based on ISTQB and JSTQB, two software-testing standards organizations. It turns identified test conditions into logical test cases using techniques such as boundary checks and decision tables.
Skill Claude CodeCodex
A testing workflow that runs automated tests or records results from manual tests. It organizes failures as possible defects in a file named test-execution-log.md.
Skill Claude CodeCodex
A test-implementation skill that turns designed test cases into runnable automated tests or executable manual procedures. Test doubles are controlled replacements such as mocks, stubs, or fakes used by automated tests.
Skill Claude CodeCodex
A testing-monitoring setup guide based on ISTQB and JSTQB practices. It defines measures such as progress, test coverage, failure rate, flaky-test rate, and links between risks and test cases, then helps build the systems that collect them.
Skill Claude CodeCodex
A written plan for testing a product, based on the risks that could cause the most harm. It defines what to test, where to focus effort, and when testing can start or finish.
Skill Claude CodeCodex
A test-results review skill that compares recorded test runs with the project's exit criteria—the conditions that must be met before testing is considered complete.
Skill Claude CodeCodex
A review gate for software-testing documents and results, based on ISTQB/JSTQB testing processes. It performs fixed checks, optional qualitative review, and records whether each stage passes, passes with conditions, or must be redone.
Agent
A read-only reviewer for software testing documents, such as test plans, test designs, execution logs, monitoring definitions, and completion reports. It checks them against ISTQB/JSTQB testing guidance.
