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

No annotations are provided, so the description must carry the full burden. It discloses that the tool returns counts of templates, languages, and legal areas, which implies a read-only operation, but it does not explicitly state safety, authorization requirements, or return format. The description is minimal and does not add behavioral context beyond the basic overview statement.

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 description is a single concise German sentence that front-loads the purpose ('Überblick über Tamgara') and lists the included data elements. There is no wasted wording, and it is easily scannable for an agent.

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 zero-parameter tool with no output schema, the description adequately covers the tool's purpose and the key data points returned (counts of templates, languages, legal areas). While it does not specify exact response structure, the simplicity of the tool reduces the need for more detail. It is complete enough for the agent to select it correctly.

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?

The tool has zero parameters, and the schema coverage is therefore 100% by default. The description correctly avoids adding parameter information since none exist. This matches the baseline for a no-parameter tool, and the description is sufficiently clear without needing to elaborate on inputs.

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 states the tool provides an overview of Tamgara, specifically counts of templates, languages, and legal areas. This clearly identifies the resource and the nature of the output. It distinguishes from siblings like list_languages or list_categories by focusing on aggregate counts rather than individual listings, though it does not name any sibling explicitly.

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?

The description implies the tool is for getting a high-level summary, but it does not explicitly state when to use it instead of alternatives. Given siblings like list_languages, list_categories, and get_provider, the description lacks direct comparison or exclusion guidance. The context is clear enough that a user would use it for an overview, but no when/when-not is provided.

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