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

The readOnlyHint annotation already signals a safe read, and the description adds scope context: only upcoming earnings conferences for followed companies. It does not disclose any additional behavioral traits such as authentication, default window behavior, or response shape, but with the annotation present this is acceptable.

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?

The description is a single concise phrase with no filler or repetition. It is appropriately sized for a simple getter, though it lacks the structured detail that could make the tool stand out from siblings.

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?

For a low-complexity read tool with two optional documented parameters and readOnlyHint, the description conveys the core return set but leaves some ambiguity about what a 'reminder' includes and whether the followed-company scope is the user's watchlist. It is minimally complete but not rich.

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 schema covers both optional parameters with clear descriptions: symbol is a canonicalized single-symbol filter and daysAhead has a default/max. The description adds no parameter meaning, so it earns the baseline score for high schema coverage.

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 Polish description translates to 'Upcoming earnings conferences of companies you follow,' which identifies the returned resource and its personalized scope. It is clear but uses a noun phrase rather than an explicit verb such as 'returns' or 'lists,' so it stops short of the top rating.

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?

The description gives no guidance about when to choose this tool over siblings such as get_conference_summary or get_earnings_calendar. It implies usage for tracking companies, but provides no exclusions or alternative routing.

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