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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds the required auth scope (read_content) and the underlying REST path, both useful beyond the annotations, but says nothing about result ordering, pagination behavior, or empty results.

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?

Three short sentences, purpose front-loaded, with permission and endpoint as supporting detail. Nothing is wasted and nothing is buried.

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 read-only, zero-required-parameter list tool with full schema coverage and annotations covering the safety profile, the definition is nearly sufficient. The only minor gap is that, with no output schema, the description gives no hint of the shape of the returned blog list.

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%: page, limit and the visibility enum are all documented in the schema, including the "pass the previous reply's next_page" pagination convention. The description adds no parameter meaning beyond that, so the baseline 3 applies.

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 and resource ("List the store's blogs"), which is unambiguous and distinct from sibling list endpoints such as list_articles and list_pages. It doesn't explicitly contrast itself with those siblings, leaving that inference to the resource name alone.

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?

"Needs read_content" gives a genuine prerequisite for calling it, which is more than most siblings offer. However, there is no explicit when-to-use/when-not-to-use guidance or routing to alternatives (e.g., when a single-blog fetch is preferable).

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