update_subtopic

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

Annotations already indicate this is not read-only and not explicitly destructive; the description's 'Edit' is consistent but adds no behavioral context beyond that. It does not disclose merge semantics for null fields, return value, permissions, or side effects, so it provides little transparency beyond the structured annotations.

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, front-loaded sentence with no wasted words. It is concise, though slightly repetitive of the tool name and parameter names, so it does not reach the exceptional level of fully optimized descriptions.

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 simple update tool with a fully documented schema and annotations, the description is minimally adequate. However, it omits useful context like partial-update behavior, whether null clears or preserves fields, and what the tool returns, so an agent would benefit from more guidance.

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 description coverage is 100%, so the parameters are already well documented. The description only restates the field names 'name' and 'description' without adding new semantic meaning such as what omission or null means for each field.

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 ('Edit') and resource ('subtopic') and names the editable fields ('name or description'). It is clear enough to be distinguished from create_subtopic, delete_subtopic, and list_subtopics, though it does not explicitly call out alternatives.

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 gives no guidance on when to use this tool versus siblings such as create_subtopic, delete_subtopic, or list_subtopics. There are no prerequisites, exclusions, or alternative routing, so an agent must infer usage solely from the verb 'Edit'.

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