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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value beyond them by disclosing the return content: a plain-language definition plus a dictionary link, which is important since no output schema exists. It does not state behavior for unknown or misspelled terms, which is the only notable gap.

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: source dictionary, output content, and examples in that order. The nested parenthetical example list is dense but still readable, and nothing in the sentence is redundant.

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 one-parameter lookup tool with no output schema, the description covers the essential pieces: what is looked up, from which source, and what comes back (definition + link). The remaining omissions (not-found behavior, exact-match requirement) are minor for this complexity level.

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 0% for the single 'terim' parameter, so the description must carry the burden. It partially does by giving four example term values that illustrate the expected vocabulary, but it never says whether an exact dictionary headword is required or whether free-form phrasing is accepted. Helpful examples without matching rules keeps this at a mid score.

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 concrete verb+resource: retrieving the plain-Turkish definition of a term from the 'Ortak Alan Legal Tech' dictionary, plus a link. The parenthetical examples (e-tebligat, KVKK, akıllı sözleşme, e-imza) make the term domain unmistakable. It does not explicitly contrast with siblings, though the siblings (doviz_ve_gostergeler, son_yazilar, tarif_bul, yazi_ara, yazi_ozeti) are clearly different tasks, so confusion risk is low.

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 only implied: an agent can infer it should call this when a Turkish legal/Legal Tech term needs explaining. There is no explicit when-to-use or when-not statement, no guidance on what to do if a term is not in the dictionary, and no named alternative tool. Adequate but leaves the routing decision to inference.

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