Generate monthly marketing content calendars for e-commerce brands
The server defines a single tool 'generate' with a basic schema and minimal documentation. The tool has a description and input schema present, but the description is too generic and lacks the depth needed for LLM guidance on when/why to use it. The schema is present but underdeveloped: no output schema is documented, parameters lack detailed descriptions explaining constraints or dependencies, and there is no error handling guidance. The implementation is purely computational (no external APIs called) but lacks production-grade documentation patterns. No tool annotations (readOnlyHint, idempotentHint, etc.) are present. The code-visible schema is basic and would not meet A/B-tier tool standards.
Generate a full monthly content calendar
Tool description is generic and lacks LLM guidance. Description 'Generate a full monthly content calendar' (44 chars) is below the recommended 50-200 char range (Baseline: avg 194 chars). Does not explain WHEN to use this tool, WHAT the output contains, or any prerequisite setup.
Output schema is not documented. The tool returns a dict with calendar entries, themes, hashtags, and posting schedule, but LLMs have no visibility into the response structure. This forces LLMs to guess field names and types, risking downstream errors.
Parameter descriptions are minimal. 'channels' is described only as 'Social platforms to schedule for' (38 chars) with no mention of valid values or format. 'month' lacks range explanation (must be 1-12). 'product_category' says 'beauty / fitness / fashion / food / tech / default' but this should be an enum constraint, not a description.

No enum constraints defined for 'product_category' or 'channels'. Free-form strings invite hallucinated values. JSON Schema should enforce product_category as enum: ['beauty', 'fitness', 'fashion', 'food', 'tech', 'default'].
No error handling guidance. If an invalid month (e.g., 13) or invalid category is passed, there is no documented response or recovery path. No validation errors or actionable messages returned.
Tool name 'generate' is generic and does not follow verb_noun pattern. Better name would be 'generate_content_calendar' to be more specific and reduce LLM ambiguity when multiple generation tools exist.
No tool annotations (readOnlyHint, idempotentHint, destructiveHint) in the schema. This tool is read-only and idempotent (safe to retry), but LLMs have no explicit signal.
