get_financial_report_latest

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, covering safety and nature. The description adds minor context about it being a 'quick snapshot' but doesn't elaborate on data freshness, availability, or potential empty results. No contradictions.

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 extremely concise with no wasted words. It includes a strategy hint and a usage example, which are valuable. Every sentence earns its 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?

The tool is simple (1 param) and has an output schema (not shown). The description covers the core purpose and basic parameter. It lacks guidance on edge cases like missing data, but overall sufficient for a low-complexity tool.

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 input schema has 0% coverage, so description must compensate. It only states 'symbol: Security symbol' which is generic. The example shows a format (000001.SZ) but doesn't explain the pattern or exchange suffixes. More detail is needed.

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 retrieves the latest financial report summary and lists specific metrics (revenue, net profit, EPS, ROE). The verb 'Get' and resource 'latest financial report summary' are specific. However, it does not explicitly differentiate from siblings like get_financial_metrics or get_financial_statement, leaving some ambiguity.

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 strategy tag 'Quick snapshot of latest quarterly/annual results' implies usage context, but no explicit when-to-use or when-not-to-use guidance is provided. Given the many sibling tools, more specific direction would be beneficial.

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