Remote skills and bundles can resolve the same repository into separate caches. Reuse Foundation's optional immutable source store so an adopted exact repository/commit has one shared source object.
Existing skill copies and local edits remain authoritative until safe staging adoption. Bare Git URLs keep the Skills default main ref. Without the compatible Foundation API, the legacy resolver continues to work.
Depends on microsoft/amplifier-foundation#415 for shared-store opt-in; staggered upgrades remain supported. Recommended merge order: Foundation, Skills, Unified.
Validation: all 12 focused skill-source tests passed with the Foundation branch API, including shared bundle/skill reuse, default-ref behavior, legacy edit protection and absent-API compatibility. No live-service migration was performed.
Related consumer PR: microsoft/amplifier-unified#315.
Add generic
tool-skills.config.cache_dirfor hosts that share settings andlocal skills but own remote downloads. Both startup and on-demand resolution
honor it; omitted configuration retains CLI defaults. Explicit paths remain
authoritative. Follow-up source/cache coverage: 38 tests passed; additional
mount, hook and multi-source coverage: 35 passed.
