update_title

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

Annotations already indicate that this is a write operation (readOnlyHint=false) and non-destructive. The description adds no further behavioral context, such as which fields are modified or whether an existing title is required, so it provides no value beyond the 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 short sentence, which is efficient. However, it is under-specified and nearly duplicates the annotation title 'Update Title', so it does not add enough informational value to fully justify its presence.

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 two parameters and no output schema, the description still lacks essential context such as return value, prerequisites (e.g., existing title), or side effects. Annotations provide some transparency, but the description is too minimal to give a complete understanding.

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?

With schema description coverage at 50% (only title_id is described), the description could have clarified the 'name' parameter but does not. It offers no parameter-level explanation, leaving the semantics of 'name' and 'title_id' to be inferred from the schema and tool 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 'Edit a title' clearly specifies the action (edit) and resource (title), distinguishing it from sibling tools like create_title, delete_title, get_title, list_titles, and search_titles. It is not a tautology because it uses a specific verb rather than repeating the tool name.

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 alternatives. It does not mention prerequisites, such as the title existing, or contrast with create_title or delete_title, leaving the usage context entirely implicit.

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