EnvMem has well-structured tool definitions with complete schemas and descriptions for all 8 tools. Naming follows verb_noun convention (search_, get_, list_, add_, delete_, clear_, import_). Descriptions are clear and contextual (avg ~120 chars). However, several tools lack output schema documentation, parameter descriptions are sometimes generic, and error handling guidance is minimal. The tool set is cohesive but some parameter constraints could be more explicit (e.g., limit bounds, enum validation for category).

• Document output schemas for all 8 tools. Example: search_env_variables returns {results: [{name, description, category, service, required}], total_count, query}. This enables LLMs to chain tools and extract fields.
• Add recovery guidance to error scenarios. E.g., get_env_by_name: 'If the variable is not found, try search_env_variables() with a partial name or category filter.'
• Expand parameter descriptions with constraints and examples. E.g., limit: 'Maximum number of results (1-50, default 10). Larger limits may slow search.' category: 'Optional filter. Valid values: ai_services, browser_automation, database, monitoring, deployment, auth, analytics, storage, email, sms, social, cms, payment, other.'
• Add a confirmation step or dry-run mode to delete_env_variable and clear_all_env_variables. E.g., add a dry_run=true parameter that returns what would be deleted without actually deleting.
• Document import_env_variables parsing rules: 'Accepts .env format (NAME=value). Lines starting with # are comments. Invalid variable names are skipped with a warning. Returns {imported: N, skipped: M, errors: [...]}.'
