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

Annotations already declare readOnlyHint, idempotentHint and non-destructive behavior, so safety is covered. The description adds two facts not in the annotations — a 200-item cap and that the call is free — which is useful context. It still omits ordering, what happens when more than 200 tenders are saved, and the returned shape.

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?

A single front-loaded sentence with no filler; the cap and cost note are packed into the same clause. Every element earns its place.

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 parameterless, read-only list tool with no output schema, the description covers what is returned (saved tenders), whose they are (the owner's), the maximum count (200), and the cost (free). Only ordering and truncation behavior remain unstated, which is a minor gap given the tool's simplicity.

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 takes zero parameters, so the baseline is 4. With an empty schema there is no parameter meaning for the description to add or omit, and nothing is misrepresented.

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 ('Lists ... tenders saved by the owner') and scopes the result set to the owner's saved items, which separates it from search_tenders and open_tenders_in_field. It does not name a sibling explicitly, but the 'saved' resource is unambiguous against the surrounding tool set.

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?

There is no when-to-use guidance, no mention of when to prefer it over search_tenders, and no stated prerequisites such as needing saved items to exist. The word 'free' hints at cost behavior but says nothing about when this call is the right choice.

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