kimi-mem provides 9 tools with consistent naming (memory_* prefix) and reasonable descriptions in Chinese. However, critical gaps undermine production readiness: (1) Parameter descriptions are minimal or absent for many fields (e.g., memory_search's 'scope' enum lacks explanation of project vs all-projects semantics); (2) Output schemas are completely undocumented, no tool declares what fields it returns, forcing LLMs to guess; (3) Error handling is absent, no guidance on recovery, retryability, or actionable error messages; (4) No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels (DESTRUCTIVE, WRITE); (5) Chinese descriptions limit accessibility for English-speaking agents and developers. Naming is consistent but generic (memory_* verbs are clear). Schemas are present in input but lack depth and output documentation.

• Document output schemas for all tools. For memory_search, specify: returns array of {id, content, type, tags, projectPath, score, timestamp}. For memory_profile, specify: returns {preferences: {...}, stats: {...}}.
• Expand parameter descriptions. For memory_search.scope, write: 'project = search only current project (default); all-projects = search across all projects in memory store.' For memory_add.type, write: 'fact = static information; decision = architectural/process choice; problem-solution = bug fix or workaround; gotcha = pitfall or edge case; preference = user/team preference.'
• Add error handling guidance. For memory_forget, document: 'Returns 404 if id not found. Idempotent, calling twice with same id succeeds both times.' For memory_import, document: 'Returns 409 if duplicate id exists (dryRun=true to preview conflicts).'
• Declare tool annotations in MCP schema. Add readOnlyHint=true to memory_search, memory_list, memory_profile, memory_export, memory_list_shards. Add destructiveHint=true to memory_forget. Add idempotentHint=true to memory_profile.
• Translate descriptions to English or provide bilingual descriptions. Current Chinese descriptions block non-Chinese-speaking agents and developers from understanding tool semantics.
