Single tool 'saveArticle' has a basic schema with 4 required parameters, but critical quality gaps undermine production readiness. Tool description is minimal (22 chars in Chinese, non-English). Parameter descriptions exist but are terse (8-16 chars each). No output schema documented. No error handling guidance. No idempotency markers despite being a destructive write operation. Parameter naming inconsistency: 'Description' (capitalized) vs lowercase others. No validation constraints (e.g., tag format, content length limits). Tool lacks English descriptions, making it inaccessible to English-speaking LLMs and violating accessibility norms for international MCP servers.

• Provide English tool description (50-150 chars): 'Publish a markdown article to CSDN with title, content, tags, and summary. Returns article_id and published URL. Irreversible operation.'
• Document output schema with fields: article_id (string), article_url (string), publish_time (ISO 8601), status (enum: success|error), error_message (string if status=error).
• Rename parameter 'Description' to 'description' (lowercase) for consistency with other params and JSON naming conventions.
• Add parameter constraints in descriptions: 'tags: comma-separated, max 5 tags, each 1-20 chars'; 'title: 1-200 chars'; 'markdowncontent: 1-100000 chars'.
• Add error handling guidance: 'If publish fails due to auth, verify CSDN_COOKIE env var is set. If content is rejected, check for unsupported markdown syntax. Retry is safe if status=error; do not retry if status=success.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
