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

Annotations already declare the operation is a non-read, idempotent, non-destructive mutation, so the safety profile is covered. The description adds nothing beyond annotations that carries behavioral meaning: it does not say whether the update is a partial merge or full replace, what permissions are needed, or how unpublished/unset fields are treated. The comment-policy list simply restates the schema enum.

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 tight segments, front-loaded with the action and fields, followed by the enum values. Every sentence is short and there is no filler, though the enum listing partially duplicates the schema's enum declaration.

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 mutation with no output schema and annotations covering the safety profile, the definition is minimally adequate. However it omits partial-update semantics and permission requirements, which are the main remaining gaps an agent would want before invoking it.

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 coverage is only 20% (just blogId = 'Blog GID'), so the description has to compensate. It usefully names the four optional fields (title, handle, template suffix, comment policy), giving the agent an inventory of what is updatable, but it adds no format or syntax detail and does not clarify the relationship between handle and templateSuffix.

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?

States a specific verb (update) and resource (blog) and enumerates the four mutable fields, so an agent can immediately tell this apart from read siblings like shopify_get_blogs and shopify_get_blog_by_id. It does not explicitly name any alternative tool, but the write verb plus the 'blog' resource makes the purpose unambiguous.

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?

No guidance on when to use this versus other update tools, no prerequisites (e.g. a valid blogId), and no statement that only supplied fields change. The description is purely a field inventory with no contextual routing.

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