Agent2Pieces defines 2 tools with basic schemas but significant quality gaps. Both tools have descriptions (10-20 chars baseline), but parameter descriptions are entirely missing, critical for LLM reasoning. Input schemas are present but lack parameter-level descriptions, violating the 100% A+ baseline. The write tool (create_pieces_memory) has 6 properties with no type info beyond the property names; the search tool has 3 properties similarly undescribed. No output schema documentation. Error handling and recovery guidance absent. Tool naming is reasonable (verb_noun pattern), but parameter naming lacks clarity (e.g., 'externalLinks' vs 'external_links' inconsistency). No evidence of idempotency, pagination support, or composition patterns.

• Add parameter descriptions to all 9 parameters. Example: 'summary_description (string, required): Brief one-line summary of the memory. Used for display in Pieces UI.' Follow 50-200 char baseline.
• Document output schemas for both tools. For create_pieces_memory, specify returned fields (id, created_at, etc.). For annotations_full_text_search, document annotation object structure and pagination fields.
• Add type constraints and bounds: limit (integer, 1-100, default 20), cursor (string, optional, opaque pagination token). Replace free-form 'files' and 'project' with typed enums or structured objects.
• Implement error handling patterns. Return actionable errors: 'Invalid summary_description: must be 1-200 chars' instead of generic failures. Add recovery hints: 'If memory creation fails due to duplicate, call annotations_full_text_search to verify.'
• Standardize parameter naming to snake_case throughout (externalLinks → external_links, connected_client stays). Align with Arcade baseline for LLM parsing consistency.
