Sthayi demonstrates strong naming conventions (verb_noun pattern: memory_search, memory_write, memory_review, memory_consolidate, memory_pack, memory_entities, memory_journal) and comprehensive parameter schemas with type definitions, enums, and constraints. Descriptions are detailed and contextual (avg ~180 chars), explaining WHAT each tool does and WHEN to use it. However, several parameters lack descriptions (e.g., 'scope' in memory_search has minimal guidance on valid values like 'user' vs 'project:<name>'), and output schemas are not explicitly documented in the visible code. Error handling is present but recovery guidance is sparse. Tool composition is excellent, each tool has a single responsibility and outputs chain naturally (e.g., memory_search returns ranked results suitable for memory_write input).

• Document output schemas for all tools. For memory_search, specify: returns array of {id, content, type, score, confidence, recency, scope}. For memory_write, specify: returns {ids: string[], status: 'proposed'|'confirmed', warnings: string[]}. This enables LLMs to plan downstream calls and extract the right fields.
• Enhance 'scope' parameter descriptions across memory_search, memory_write, memory_pack, memory_entities. Add: 'Scope filter (e.g., "user" for user-level memories, "project:myproject" for project-scoped). Omit to search all scopes.'
• Move 'apiKey' from memory_consolidate parameters to server-side environment variable injection (e.g., STHAYI_CONSOLIDATE_API_KEY). Update description: 'API key is read from environment; do not pass as parameter.'
• Add conditional parameter documentation to memory_consolidate: 'If mode=oracle, provider and model are required. If mode=deterministic, they are ignored.'
• Expand error messages in tool results. Instead of 'committed_unanchored', return: 'Write succeeded but anchor failed. Journal is durable; retry the operation or check memory_journal to verify. If failures persist, contact support.' This guides the LLM's next step.
