get_morningstar_report

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description does not disclose any behavioral traits such as rate limits, required permissions, or side effects. It is likely a read operation but this is not explicitly stated.

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?

Description is very short with one sentence and some keywords. It is concise but lacks structure; it does not usefully front-load information for an agent. Could benefit from a clearer explanation of what a Morningstar report contains.

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?

Given the simplicity of the input schema (one param) and absence of output schema, the description is incomplete. It fails to explain return format or content, leaving the agent guessing about what data will be retrieved.

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?

The only parameter 'code' has no description in the schema or the tool description. Description does not clarify that 'code' is a stock or REIT ticker symbol. With 0% schema description coverage, the description adds no value to parameter understanding.

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?

Description clearly states it provides Morningstar research reports including fair value, moat, and bull-bear analysis for stocks and REITs. It distinguishes from siblings by focusing on Morningstar's proprietary research, but does not explicitly differentiate from other research tools like get_analyst_consensus.

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 get_company_profile or get_analyst_consensus. Description only states what it is, not when it is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
