get_blog_post

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

The description adds no behavioral context beyond what annotations already state. Annotations declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, but the description does not add information about outcomes, errors, return behavior, or access requirements.

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 very short, but it is under-specified rather than deliberately concise. It repeats the tool name without adding useful detail, so it does not earn its place as a helpful definition.

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 tool with one well-documented parameter, strong annotations, and an output schema, this is minimally viable. However, it lacks useful information about how it relates to list_blog_posts and when an agent should choose 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?

The input schema fully documents post_id as a 'Blog post UUID' with 100% coverage. The description adds no additional meaning for the parameter, so the baseline of 3 is appropriate because the schema already carries the semantic weight.

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 clearly states the operation ('Get') and resource ('Blog Post'), which is specific enough to indicate it retrieves a single blog post. However, it does not explicitly distinguish itself from siblings such as list_blog_posts, and it largely restates 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?

There is no guidance on when to use this tool vs alternatives. It does not mention that list_blog_posts should be used for fetching multiple posts, nor does it describe prerequisites or context for retrieving a single post.

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