EREBYX SDK exposes 5 memory-management tools with partial schema coverage. All tools have descriptions (10-50 chars, below the 50-200 char baseline for LLM optimization), and input schemas are present but lack critical detail. Parameters are typed but descriptions are minimal or absent for many fields. No output schemas documented. Error handling and recovery guidance are absent. The builder-pattern API design is sound for composition, but tool definitions themselves lack the rigor expected of production-grade agent tools.

• Expand tool descriptions to 50-200 characters. Example: 'save: Persist a memory with optional metadata (category, importance, anchors). Returns memory_id for later retrieval. Call after restore_identity to bind memory to session context.'
• Document output schemas for all tools. Example: 'search returns {results: [{memory_id, content, category, created_at, importance}], total_count, next_cursor}'.
• Add parameter descriptions for all fields. For 'anchors', explain: 'Domain anchors (e.g., "project:acme", "user:alice") filter memories by context. Comma-separated strings.' For 'detail_level', use enum: 'full|summary|minimal'.
• Add error handling and recovery guidance to tool descriptions. Example: 'If search returns empty, try broader queries or check restore_identity was called first.'
• Document tool sequencing in descriptions. Example: 'restore_identity: Call this first at session start to load user identity. Required before save/search/load_context.'
