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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered by structured data. The description goes beyond that by stating the return shape ('titles, summaries and links'), which the annotations do not convey, though it says nothing further about result limits or freshness.

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?

One compact sentence with a parenthetical topic list plus a short return-value clause; the resource being described leads and the parentheses are the only slightly bulky part. Nothing is wasted, though the example list could be trimmed.

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?

With only two fully-documented parameters and no output schema, the definition covers what the tool returns (titles, summaries, links) and what it is about. The one remaining gap for an agent is knowing how many guides come back or whether results are ranked, which the description does not address.

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 100% — both 'query' and 'country' are documented with examples in the schema itself. The description adds no syntax or formatting guidance for either parameter, so the baseline of 3 applies.

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 names a specific resource (askTender's procurement guides) and enumerates the topic coverage (portal registration, digital signatures, bid security, foreign bidders, consortiums), so an agent can tell it is a knowledge-lookup tool rather than a tender-search tool. It does not explicitly contrast itself with siblings like get_requirements or search_tenders, which keeps it at 4 rather than 5.

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?

Usage is implied by the topic list — an agent can infer this is for 'how does procurement work' questions — but there is no explicit when-to-use statement, no when-not-to-use, and no named alternative. For a niche lookup tool the intent is reasonably inferable, so this is minimum-viable rather than a gap-free 4.

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