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

Annotations already carry readOnlyHint, idempotentHint, destructiveHint, and openWorldHint, so less description is needed. The description adds the context that the tool returns a fixed, deterministic check of one educational warehouse chain and does not mutate organization or balances, reinforcing the safety profile without contradicting 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?

Two short sentences with no filler: the first states the core return behavior, the second states what the tool does not do. The most important content is 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?

For a zero-parameter, read-only tool, the description plus annotations and an output schema cover nearly everything an agent needs. The only small gap is the slightly vague meaning of a 'fixed check', but the output schema resolves most of the ambiguity.

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?

There are zero parameters, so schema coverage is trivially 100% and the baseline is 4. The description adds a small piece of scope context by mentioning one educational warehouse chain.

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 identifies a concrete action (returns) and a concrete resource (a fixed check of one training warehouse chain), and the title suggests a safe first-day plan. It is clearly distinguished from the sibling get/list tools by content, though the title and description have a slight semantic mismatch.

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 'does not create an organization and does not change balances' line gives an implicit sense for when it is safe to call, but there is no explicit guidance compared with get_public_tool or list_public_tools. The use-case is implied rather than stated.

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