aim_create_entities

Create multiple new entities in the knowledge graph. DATABASE SELECTION: By default, all memories are stored in the master database. Use the 'context' parameter to organize information into separate knowledge graphs for different areas of life or work. STORAGE LOCATION: Files are stored in the user's configured directory, or project-local .aim directory if one exists. Each database creates its own file (e.g., memory-work.jsonl, memory-personal.jsonl). LOCATION OVERRIDE: Use the 'location' parameter to force storage in a specific location: - 'project': Always use project-local .aim directory (creates if needed) - 'global': Always use global configured directory - Leave blank: Auto-detect (project if .aim exists, otherwise global) WHEN TO USE DATABASES: - Any descriptive name: 'work', 'personal', 'health', 'research', 'basket-weaving', 'book-club', etc. - New databases are created automatically - no setup required - IMPORTANT: Use consistent, simple names - prefer 'work' over 'work-stuff' or 'job-related' - Common examples: 'work' (professional), 'personal' (private), 'health' (medical), 'research' (academic) - Leave blank: General information or when unsure (uses master database) EXAMPLES: - Master database (default): aim_create_entities({entities: [{name: "John", entityType: "person", observations: ["Met at conference"]}]}) - Work database: aim_create_entities({context: "work", entities: [{name: "Q4_Project", entityType: "project", observations: ["Due December 2024"]}]}) - Master database in global location: aim_create_entities({location: "global", entities: [{name: "John", entityType: "person", observations: ["Met at conference"]}]}) - Work database in project location: aim_create_entities({context: "work", location: "project", entities: [{name: "Q4_Project", entityType: "project", observations: ["Due December 2024"]}]})

Result:

aim_create_relations

Create multiple new relations between entities in the knowledge graph. Relations should be in active voice. DATABASE SELECTION: Relations are created within the specified database's knowledge graph. Entities must exist in the same database. LOCATION OVERRIDE: Use the 'location' parameter to force storage in 'project' (.aim directory) or 'global' (configured directory). Leave blank for auto-detection. EXAMPLES: - Master database (default): aim_create_relations({relations: [{from: "John", to: "TechConf2024", relationType: "attended"}]}) - Work database: aim_create_relations({context: "work", relations: [{from: "Alice", to: "Q4_Project", relationType: "manages"}]}) - Master database in global location: aim_create_relations({location: "global", relations: [{from: "John", to: "TechConf2024", relationType: "attended"}]}) - Personal database in project location: aim_create_relations({context: "personal", location: "project", relations: [{from: "Mom", to: "Gardening", relationType: "enjoys"}]})

Try it

Result:

aim_add_observations

Add new observations to existing entities in the knowledge graph. DATABASE SELECTION: Observations are added to entities within the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force storage in 'project' (.aim directory) or 'global' (configured directory). Leave blank for auto-detection. EXAMPLES: - Master database (default): aim_add_observations({observations: [{entityName: "John", contents: ["Lives in Seattle", "Works in tech"]}]}) - Work database: aim_add_observations({context: "work", observations: [{entityName: "Q4_Project", contents: ["Behind schedule", "Need more resources"]}]}) - Master database in global location: aim_add_observations({location: "global", observations: [{entityName: "John", contents: ["Lives in Seattle", "Works in tech"]}]}) - Health database in project location: aim_add_observations({context: "health", location: "project", observations: [{entityName: "Daily_Routine", contents: ["30min morning walk", "8 glasses water"]}]})

Try it

Result:

aim_delete_entities

Delete multiple entities and their associated relations from the knowledge graph. DATABASE SELECTION: Entities are deleted from the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or 'global' (configured directory). Leave blank for auto-detection. EXAMPLES: - Master database (default): aim_delete_entities({entityNames: ["OldProject"]}) - Work database: aim_delete_entities({context: "work", entityNames: ["CompletedTask", "CancelledMeeting"]}) - Master database in global location: aim_delete_entities({location: "global", entityNames: ["OldProject"]}) - Personal database in project location: aim_delete_entities({context: "personal", location: "project", entityNames: ["ExpiredReminder"]})
