What you can do

Need	How loci helps
Find a decision buried in your notes	Hybrid search across directories, with tag, path and date filters
Search for an exact identifier	Literal matching for `user_id`, `api/v2`, `SHT45` — a symbol does not have to win a semantic ranking
Know whether a decision still applies	`loci history` walks the supersession chain: what replaced it, and when
Ask a question and check the evidence	Answers cite source sections; optional claim-by-claim verification
Carry context between AI tools	MCP tools share one instance; durable memories are Markdown files
See what each coding agent remembers	Harness discovery, file browsing, per-tool stats and digest notes
Manage the knowledge base visually	Built-in Web console for search, Q&A, memories, indexing and audit
Resume a task exactly where it left off	Structured state by exact key (`brain_state_save` / `brain_state_get`) — no ranking in the way
Prune memory with evidence instead of vibes	Memory health: citations, corrections and age per note (`loci memory-health`)

Three kinds of "memory" fail differently, and mixing them is the classic misuse:
