get_topics

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

With no annotations available, the description bears full responsibility for disclosing behavior such as read-only nature, return format, auth requirements, or side effects. 'Repo topics/tags.' offers none of this, leaving the agent completely uninformed about the tool's runtime characteristics.

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 phrase 'Repo topics/tags.' is extremely under-specified rather than concise. It omits essential information that would make its brevity useful, similar to the 'Process' example where minimal text does not serve the reader.

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 tool with a single parameter and no output schema, a complete description would be a single sentence stating it returns the topics/tags for a given repository. The current fragment leaves purpose, parameter expectations, and behavior entirely unstated, rendering the description insufficient even for a simple tool.

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 parameter owner_repo has no schema description (0% coverage), and the description does not compensate by explaining the expected format (e.g., 'owner/repo') or its role. The tool description fails to add any meaning to the bare property name.

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 'Repo topics/tags.' is a noun phrase that identifies the resource but lacks an explicit verb such as 'get' or 'list'. It vaguely conveys the tool's subject matter but leaves the action ambiguous, though the name 'get_topics' provides some clue.

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?

There is no guidance on when to use this tool versus any alternatives, no contextual hints, and no exclusions. The description provides zero direction for selection among a large set of sibling tools.

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