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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses nothing: no side effects, required inputs, permissions, side effects, or output characteristics. The catalog reference is non-informative.

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 short, but brevity here is under-specification, not conciseness. The sentence 'Same name as the live catalog on https://...' adds no actionable information and does not earn its place. A useful description would replace it with functional content.

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 one of many similar analysis tools, has no annotations, no parameter documentation, and no output schema. The description provides none of the context an agent needs to understand inputs, expected behavior, or results. It is wholly inadequate for correct invocation.

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 tool has zero defined parameters and schema coverage is 100%, so the description does not need to explain parameters. The schema permits additionalProperties, but there are no named inputs to document. Baseline 4 for the zero-parameter case is appropriate.

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 only restates the tool name and points to a URL ('MCP-Agents tool run_earnings_analysis. Same name as the live catalog...'). It does not state what the tool does, what resource it acts on, or what outcome it produces. This is essentially a tautology and gives no basis to distinguish the tool from its many run_* analysis siblings.

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 offers no guidance on when to use run_earnings_analysis versus alternatives such as run_comps_analysis, run_credit_screen, or run_quantitative_analysis. It does not mention conditions, prerequisites, or exclusions, leaving the agent with no decision criteria.

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