Server has 7 tools with visible schemas and descriptions in Russian. Naming follows verb_noun pattern (read_, list_, generate_, create_, publish_, post_, delete_) which is good. However, descriptions are terse (avg ~60 chars, well below the 194-char baseline), lack context on WHEN to use each tool, and omit recovery guidance. Schemas are present but minimal, most parameters lack detailed constraints or format guidance. Error handling returns generic text responses without actionable recovery steps. No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels. Output schemas are undocumented. Composition is reasonable (tools are single-purpose) but parameter descriptions are sparse.

• Expand tool descriptions to 100 - 200 chars. Include WHAT the tool does, WHEN to use it (vs similar tools), and what it returns. E.g., 'Publishes a post to a single social platform. Use this for targeted posting; use publish_all() to post to multiple platforms at once. Returns the post ID and platform-specific URL.'
• Add readOnlyHint, destructiveHint, and idempotentHint annotations to tool schemas. Mark delete_post as destructive, create_post and publish_all as write operations, and list_platforms/post_status as read-only.
• Document output schemas for each tool. Define what fields the response contains (e.g., post_id, url, status, timestamp). Use JSON Schema or a structured format so LLMs know what to expect.
• Enhance parameter descriptions with format, range, and constraint details. E.g., 'scheduled_at: ISO 8601 datetime (UTC). Must be in the future. If omitted, post is published immediately.' and 'content_file: Path to JSON file in CONTENT_DIR. If omitted, uses the most recent file by modification time.'
• Implement structured error responses with error codes and recovery guidance. E.g., {isError: true, code: 'PLATFORM_UNAVAILABLE', message: '...', retryable: true, suggestion: 'Try again in 30 seconds or use a different platform.'}
