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

Annotations already declare readOnlyHint=true (safe read), and the description adds return-content context (summary, features, rating, booking URL) plus the canonical-URL guarantee. No contradiction between description and annotations; it adds useful behavioral detail beyond the structured data.

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 sentences, front-loaded with the key action ('After search, call this…'), and every clause earns its place — return contents, canonical URL note, and anti-hallucination constraint. Zero waste.

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 single-parameter fetch tool with readOnlyHint=true and no output schema, the description adequately covers what the tool returns and the required input. Could detail return formatting, but given the simplicity and annotations, this is complete enough.

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 coverage is 100% since the id parameter is fully documented as 'Kamp yeri slug'ı (search sonucundaki id)'. The description reinforces that id comes from search results but adds minimal new meaning beyond the schema, earning the baseline 3.

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 uses a specific verb+resource pattern: 'call this with the result id (slug) to get summary, features, rating and the booking URL'. It clearly distinguishes from the sibling 'search' by explicitly stating 'After search', making the fetch/get-details purpose unambiguous.

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?

States exact timing ('After search'), the required input (result id/slug), and adds a valuable constraint ('Do not invent details') that prevents hallucination. This is explicit when-to-use guidance that complements the sibling tool sequencing.

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