get_growth_estimates

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description adds only that results are broken out by period, which is mild context; it says nothing about data source, staleness, or coverage limits that would matter for a third-party analyst-estimate endpoint.

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?

Front-loaded with the core purpose, which is good, but the 'Args:'/'Returns:' boilerplate adds little and the Returns block duplicates information already carried by the existing output schema, so those lines do not fully earn their place.

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?

With an output schema present, return details need not be explained, and annotations cover the safety profile, so the description is nearly sufficient for a one-parameter read tool. Its gap is the absence of any disambiguation among dozens of sibling analyst/financial tools an agent must choose between.

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?

One parameter with 0% schema description coverage; the schema only gives the property title 'Ticker'. The description's 'Stock ticker symbol' is a marginal clarification, essentially restating the name, and adds no format, exchange, or case-convention guidance.

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?

States a specific verb+resource: 'Get analyst growth estimates' with the returned resource quantified as 'growth rate estimates for various periods'. It is clear what the tool does, but it does not differentiate itself from adjacent siblings such as get_analyst_estimates, get_eps_trend, or get_eps_revisions, which an agent could easily confuse it with.

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 indication of when to use this tool versus the many other analyst-estimate siblings, no exclusions, no prerequisites. The agent gets no routing signal at all.

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