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

With no annotations, the description must carry the full burden of behavioral disclosure. It indicates a read operation through the verb 'Get' and notes the alias, but does not mention safety, permissions, rate limits, or any side effects, which is a notable gap for a tool with no structured safety hints.

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, compact sentence that immediately states the verb, resource, and scope, and includes the alias note without redundancy. Every word earns its place, and it is efficiently front-loaded.

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 with only two parameters and no output schema, and the description covers its core purpose and alias relationship. However, it lacks any guidance on return format, usage context, or behavioral caveats, so it is adequate but not fully complete for an agent selecting and invoking the 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 fully documents both parameters (apiKey and thesisId) with descriptions, so the description adds little beyond the schema. The phrase 'for a thesis' maps to the thesisId parameter but does not enrich parameter meaning further, matching the baseline of 3 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 identifies the tool's function: retrieving heartbeat configuration and monthly cost summary for a thesis. It also explicitly states it is an alias of get_heartbeat_status, distinguishing it from that sibling tool while clarifying its role.

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 alias note implies interchangeable use with get_heartbeat_status, but the description does not explicitly state when to choose this tool over alternatives. No exclusions or preferred contexts are provided, leaving usage guidance implicit.

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