What problem does it solve? Code decisions often depend on how a specific pinned version of an external library, framework, or API behaves, and a confidently recalled answer can compile or type-check yet fail at runtime. This Skill replaces recollection with verified facts from version-matched first-party sources. ## Core Features & Use Cases - Version-anchored verification: Finds the installed version in the lockfile or manifest first, then fetches that exact version's official docs, changelog, or migration guide. - Delegated research agent: Dispatches the exo:researcher agent with the library, pinned version, and question, keeping fetched pages out of the main session context. - Cited, bounded output: Returns confirmed facts with URLs, at most ten quoted lines per source, and an explicit statement of what could not be confirmed. - Use Case: Before upgrading an API call, confirm how the pinned version of a framework handles a deprecated method, then hand the cited answer to the implementing step. ## Quick Start Ask the research skill to confirm how the pinned version of a specific library behaves for a given API question before writing the code.
