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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral context: the tool has two distinct modes depending on whether tool_id is supplied, and its output is meant to be relayed to the user before scoring. It does not describe the shape of the returned question list, which keeps it from a 5.

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 sentence, front-loaded with the primary list behavior, then the conditional tool_id behavior, then the downstream action. No filler or redundant restatement of the title.

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 read-only, single-optional-parameter tool with no output schema, the description covers both modes and the intended follow-up call. The only gap is that it does not hint at the structure of the returned questions/options, which an agent must handle to ask the user.

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%, but the single parameter is a fully enumerated enum that self-documents the valid assessment IDs. The description still adds meaning by explaining that tool_id switches the tool from list mode to question-retrieval mode, which the schema alone does not convey.

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 verb and resource ('List Yazılım Koçu's free self-assessment tools') and explicitly covers the second mode ('given tool_id, return its questions and answer options'). It also implicitly separates this tool from score_assessment, which is named as the downstream step rather than a duplicate.

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?

It gives a clear workflow: fetch questions, ask the user, then call score_assessment. That is strong when-to-use guidance and names the alternative tool. It stops short of stating exclusions or prerequisites (e.g. what happens with an invalid tool_id), so it is not a full 5.

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