financials_snapshot

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only says 'Get a snapshot' with no mention of side effects, rate limits, data granularity, or return format. This is a significant gap for a tool that is presumably a read operation but which never states so.

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, short sentence with no redundant wording. It is appropriately concise, though the brevity comes at the cost of substantive content. This is efficient but not to the point of being verbose.

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 no output schema and no annotations, the description is the sole source of context. It fails to explain what 'key financial data' means, what the snapshot contains, or how it differs from other financial tools. An agent cannot determine what to expect or when to call this tool, making it severely incomplete.

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 already provides 100% coverage for the single parameter (ticker with 'Stock ticker'). The description adds no additional meaning beyond what the schema states, so it meets the baseline for high schema coverage. No compensation needed, but also no added value.

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 states a generic action ('get a snapshot') but 'key financial data' is vague and does not specify which financial metrics or statements are included. It fails to differentiate from the many specific financials_* siblings like financials_revenue or financials_balance_sheet, leaving the agent without a clear selection criterion.

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?

There is no guidance on when to use this tool versus alternatives. No mention of scenarios, prerequisites, or exclusions. Given the large set of sibling tools, the absence of usage context makes it nearly impossible for an agent to choose this tool correctly.

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