compare_tickers

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

No annotations are provided, so the description bears full responsibility. It only says 'side-by-side technical comparison' and mentions paid requirement, but fails to disclose behavioral traits such as data source, API calls, whether it modifies state, or output format. With 0% schema coverage, the description is insufficient for safe invocation.

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 very short (8 words), which is concise, but it sacrifices substance. Important information is missing. The sentence is front-loaded with 'Paid Fintools MCP required' which is a prerequisite, not the core purpose. Better structure would place the action first.

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?

Despite having an output schema and simple parameters, the description is incomplete for a tool with 17 siblings. It lacks context on when to choose this over similar tools, what technical indicators are compared, and how results are presented. The paid requirement adds context but leaves many gaps.

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?

Schema description coverage is 0%, leaving parameters unexplained. The description does not clarify 'period' (allowed values, format) or 'tickers' (number limits, format). The default '3mo' is in schema but its meaning is not elaborated. The description adds no value beyond the schema.

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 states 'side-by-side technical comparison', which implies comparing multiple tickers technically. However, it lacks a specific verb and does not elaborate on the type of technical analysis (e.g., indicators, charts). It distinguishes from single-ticker tools like get_technical_indicators but is vague compared to potential multi-ticker alternatives.

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 siblings like get_technical_indicators or screen_stocks. The description only mentions a paid requirement, which is a prerequisite but not usage context. There are no exclusions or alternative recommendations.

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