The wiki memory

An agent needs memory across tasks. Covey keeps it as an LLM-maintained wiki of linked Markdown pages with a pgvector index.

Wiki instead of a snippet store

What makes an agent competent are the relationships between entities (customer → ticket → solution, customer → colleague), not mere text similarity. Instead of loose free-text snippets, the agent maintains linked pages — one per entity — with [[wikilinks]]. The links form the graph.

Three operations

• Ingest (in the done step): file insights onto the right page.
• Query (in the triage step): vector search returns relevant pages, plus the compact index of the whole wiki.
• Consolidation: a scheduled maintenance job merges duplicates, so knowledge condenses instead of only growing.

Hybrid storage

Pages live twice: as .md files in the sandbox home and as the source of truth in the control plane.

For humans too

The same model carries the memory of human employees: the Companion app gives a person the same apparatus, only with human_id instead of agent_id as the owner.
