| Tool | Description |
|---|---|
memorize | Store a fact with mnemonic, content, and optional tags |
recall | Search by semantic similarity |
rate | Provide useful/not-useful feedback |
link | Create typed connections between memories |
merge | Consolidate duplicate memories |
export | Save memories to markdown files (optional tag filter) |
import | Load memories from markdown files |
list-tags | List all tags with counts |
Create a trivia.toml in your project root:
# Auto-add these tags to every memorize call
[memorize]
tags = ["my-project", "backend"]
# Boost these tags in recall scoring (not a filter — all memories still searchable)
[recall]
tags = ["my-project"]
# Default tag filter for export
[export]
tags = ["my-project"]
# Optional: override database path (default: ~/.claude/trivia.db)
# database = "/path/to/trivia.db"
Config discovery walks up from CWD (or CLAUDE_PLUGIN_ROOT) to find the nearest trivia.toml. CLI flags are additive with config tags.
