# Known Content Archive
Turn material the user has already identified into a bounded, auditable local archive. The current Host performs retrieval; this Skill defines the handoff and owns durable preservation.
## Boundary
- Accept explicit URLs, local files, a supplied URL list, or a collection named precisely enough to enumerate.
- Do not expand the scope with keyword search, related links, account history, bookmarks, recommendations, or model memory.
- Use the current Mode's installed retrieval route. Prefer Agent Reach/opencli when present; do not create another cross-platform router or duplicate login storage.
- Ask for current-turn authorization before accessing logged-in or user-specific content. A public URL supplied by the user needs no extra adoption Trial.
- An inaccessible item is a recorded result, not permission to substitute a different source.
## End-to-end operation
### Retrieve
Read or download each supplied item with the smallest available Host capability:
- ordinary pages and public platform URLs: the Host's browser, web reader, or installed retrieval Skill;
- X, video, podcast, social, and creator-platform URLs: the corresponding Agent Reach/opencli route already available in the Mode;
- local files: direct local read;
- media: download only when requested or necessary to preserve the supplied item.
Keep intermediate retrieval files inside the current Case or a temporary run directory. Do not create a second global cache.
### Record the retrieval
