Changes observed during successful MCP inspections.
v1.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description lacks details on behavior such as auth needs, rate limits, or error handling. It mentions 'public' but doesn't explicitly state read-only or any constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no fluff, but could be more concise (e.g., 'Returns forecast summaries for a question'). Front-loaded with name and action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, and description does not explain what 'aggregation method' means or the structure of the returned data. Given the tool's simplicity, more detail would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Only one parameter 'id' with schema description 'Metaculus question or post id'. Tool description does not add extra meaning beyond the schema, which already covers the parameter well (100% coverage). Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it returns forecast summaries for one question, using verbs like returns and resource like forecast summaries. It distinguishes from siblings like metaculus_question_forecast_history by specifying 'latest' and 'by aggregation method'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like metaculus_question_forecast_history or metaculus_question. The description does not mention use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
