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

The description and parameter notes repeatedly say values are 'discarded,' which usefully signals that the tool ignores input and likely has no side effects. However, the url parameter is described as 'HTTPS URL to normalize or cite,' which contradicts the discard theme and creates confusion about actual behavior. With no annotations, the description carries the full burden but only partially delivers.

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 two sentences and front-loads the core purpose: 'Return a three-step thinking template.' The second sentence provides useful behavioral context without padding. It is appropriately minimal, though it could benefit from a brief example of the template.

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 7 parameters and no output schema, the description never explains what the 'three-step thinking template' actually contains or how the parameters relate to it. An agent cannot tell what the return value looks like or why this tool exists alongside its many siblings. The parameter set (ref, url, city, feed, host, json, path) is not reconciled with the stated purpose, leaving a large contextual gap.

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 provides descriptions for all 7 parameters, so schema_description_coverage is 100%. The description itself adds no parameter-specific semantics beyond the high-level 'Prompt discarded.' A score of 3 aligns with the baseline 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 description clearly states a specific verb and object: 'Return a three-step thinking template.' This is not a tautology and gives the agent a concrete idea of what the tool does. However, it does not differentiate among sibling tools, and the meaning of 'Prompt discarded' as a qualifier is somewhat unclear.

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 is provided about when to use this tool versus any alternative. The description does not mention scenarios, prerequisites, or exclusions, and there is no comparison with sibling tools. Agents are left to infer when this should be invoked.

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