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

Annotations already declare readOnlyHint, idempotentHint, non-destructive behavior, and a closed-world scope. The description adds that the output is a bounded section rather than the full report, which is useful context, but it does not disclose rate limits, auth requirements, or other behavioral details beyond the annotations.

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 front-loaded sentence with no filler, so it is concise and structurally clear. However, its extreme brevity is under-specification rather than pure efficiency for a 13-parameter tool.

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?

For a complex tool with 13 parameters, 8 required, and 0% schema description coverage, the description is not complete enough. It does not explain the required birth/location data or how the section enum maps to report content, though the output schema exists and annotations cover safety.

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% for 13 parameters, including 8 required birth-data and location fields. The description mentions only 'section' generically and adds no meaning for date, time, place, latitude, longitude, timezoneOffset, or the optional parameters.

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?

States a specific verb and resource: returns one bounded section of the full report. The limitation for clients with limited context windows helps distinguish it from the broader generate_full_life_report tool, though that sibling is not named explicitly.

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?

Implies usage when context windows are limited, but does not explicitly say when to use this instead of generate_full_life_report or other report tools. No prerequisites or exclusions are provided.

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