Add Stack Context

Inventory the stack

Build a checklist of the direct technologies that shape how the project is built or operated from manifests and configuration files. Include frameworks, libraries, developer tools, and hosted services; exclude transitive dependencies. Use lockfiles to confirm installed versions, not to expand the checklist. If the project does not declare a stack yet, ask the user what they intend to use.

Resolve each technology

For every checklist item, search the vendor's current documentation and official organization for official agent context. Match the installed version when the vendor provides version-specific context.
