Manage Qdrant vector collections for storing embeddings.

IMPORTANT: You must specify a subcommand (create, list, info, delete, or items).

Subcommands (required):

• create: Create a new collection with specified embedding model
• list: List all collections in Qdrant
• info: Show detailed information about a collection
• delete: Delete a collection permanently
• items: List indexed files/repos in a collection

Common Options:

• --json: Output in JSON format for programmatic use

Collection Types:

Collections should specify a type (pdf or code) to ensure content matches:

• pdf: For document collections (PDFs, text files)
• code: For source code repositories

Available Models:

• stella: 1024D, best for documents and PDFs (default for pdfs)
• jina-code: 768D, optimized for source code (default for code)
• bge: 1024D, general purpose
• modernbert: 1024D, newer general-purpose model

Related Commands:

• /index pdf - Index PDFs into a collection
• /index code - Index source code into a collection
• /corpus create - Create both vector and full-text indexes

Implementation:

• Defined in RDR-003 (Collection Creation)
• Enhanced in RDR-006 (Claude Code Integration)
• Type enforcement added in arcaneum-122
