What problem does it solve? Test planning often relies on local-path inspection, model memory, or implicit environment assumptions to pick test tools, which produces unverifiable and non-reusable selections. This Skill turns repository scripts, CI configuration, runbooks, and tool documentation into a reviewed test-tool catalog that downstream test flows can select by stable XID references. ## Core Features & Use Cases - Tool Inventory Building: Inspects repository test projects, CI/CD configuration, build manifests, runbooks, and prior test evidence to catalog each tool or tool family with purpose, owner, setup, data, execution, and evidence-capture requirements. - Applicability Matrices: Records domain, environment, test-level, and target-type applicability for every tool, plus limitations, unsafe uses, freshness, and recheck conditions. - Gap and Unknown Tracking: Marks unverifiable capabilities as unknown and records tool gaps separately so unsupported assumptions never become selectable tools. - Publication Handoff: Produces either a run-local draft or a publication-ready, path-free artifact handed to the domain-knowledge publication path so test_flow can select it by XID. - Use Case: Before designing integration and regression tests for a staging environment, run this Skill to catalog the organization's API, DB, and batch test tools so the test plan references verified tools instead of guessed local scripts. ## Quick Start Ask the agent to prepare a test-tool catalog for your target domain and environments, specifying the test levels in scope and whether the result should be published as canonical domain knowledge.
