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

Annotations already cover read-only, idempotent, open-world and non-destructive, so the safety bar is met; the description goes beyond them with cost ('1 request unit per call'), plan availability, and the inclusion of extra/mükerrer issues. It also discloses that the payload is JSON in Turkish with source and `guncelleme` fields, which no annotation provides. It stops short of stating pagination or response-size behavior, which keeps it off 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?

The core behavior and the alternative route are front-loaded in the first two sentences, with operational metadata (endpoint, plan, cost, format) packed into a short trailing line. Every sentence carries information, though the literal endpoint path is largely inferable from the tool name and is the one marginally expendable element.

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 no output schema, the description carries the burden of describing returns and does so concretely: item types, number, issuing body, title, link, plus source and `guncelleme` fields. For a zero-required-parameter read tool, an agent has everything needed to call it and interpret the result.

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?

There is a single optional boolean parameter with 100% schema description coverage, so the schema fully documents `ilanlar`. The description never mentions the announcements toggle, and its note about extra (mükerrer) issues is not the same thing, so it adds no meaning beyond the schema. Baseline 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?

States a specific verb and resource ('Returns the most recent issue of Turkey's Official Gazette') and adds scope detail that matters: extra (mükerrer) issues are included, and the item payload is enumerated (type, number, issuing body, title, link). The sibling resmigazete_ara is explicitly cast as the older-issue counterpart, so the two can be told apart without opening a schema.

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?

Gives an explicit alternative and the condition that selects it: 'Use resmigazete_ara to search older issues.' It also flags plan availability (all plans, including free) and cost, which is the practical gating information for whether to call it.

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