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

Annotations already mark this as readOnly=false and destructiveHint=true, so the mutating nature is known. The description adds owner/admin access requirements and identifies exactly which settings may be overwritten, which is useful operational context beyond the annotation data.

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?

Two compact sentences carry the entire message with no filler. The main action and field list are front-loaded, followed by the permission requirement.

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 a full input schema, an output schema, and annotations covering mutation, the description is nearly sufficient. It could be improved by explicitly routing metadata or domain changes to sibling tools, but the provided field list and permission note make it complete for the core settings-update case.

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 parameters are already fully documented. The description only restates the field names in prose and adds no format, constraint, or relationship details beyond the schema, matching the baseline for high coverage.

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 identifies a concrete action and resource: updating blog settings, and enumerates the affected fields (name, subdomain, description, logo). It is not tautological, though it does not explicitly distinguish itself from sibling tools like update_blog_metadata or update_blog_domain.

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 field list makes the primary use case clear, and the permission prerequisite 'Requires owner or admin access' gives an explicit condition for invoking it. It does not name alternatives or state when not to use it, but the context is sufficiently clear for a settings-update task.

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