Two tools with complete Zod schemas and descriptions, but significant quality gaps. Tool names lack action verbs (memory, checkpoint instead of read_memory/write_memory/set_checkpoint). Descriptions are present but generic, memory's description is 180 chars (within baseline 194 avg) but conflates multiple operations (read/write/append/delete) into one tool, violating single-responsibility. Parameter descriptions exist but lack actionable constraints (e.g., 'topic' has no format guidance; 'mode' enum is present but only relevant conditionally). No output schema documentation. Error handling returns plain text without recovery guidance. German descriptions reduce LLM clarity in English-dominant environments.

• Rename tools to action-verb form: read_memory, write_memory, append_memory, delete_memory, set_checkpoint. This enables LLM to infer intent from name alone.
• Split 'memory' tool into five separate tools (one per operation). Each tool has a single responsibility, clearer schema, and no conditional mode logic.
• Add format constraints to 'topic' parameter: max 100 chars, alphanumeric + underscore + slash, no leading/trailing slashes. Document in description: 'Topic path (e.g., decisions, architecture, entities/auth). Max 100 chars, alphanumeric + underscore + slash.'
• Document output schema for all tools. E.g., memory read returns {topic: string, content: string, updated: ISO8601}. Checkpoint returns {success: boolean, checkpoint_id: string}.
• Enhance error messages with recovery guidance. E.g., 'Memory topic "xyz" not found. Call read_memory with no topic to list available topics.' This guides LLM to self-correct.
