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

Annotations already cover the safety profile with readOnlyHint, idempotentHint, and destructiveHint=false. The description adds that only published posts are returned and that tag/author filtering is available, but it does not disclose ordering, pagination behavior, or other runtime traits beyond what the schema and annotations already establish.

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 two sentences, front-loaded with the core action and object, and contains no filler or redundant restatement of schema fields. Every phrase contributes either topical scope or a filter capability.

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 read-only list operation with fully documented optional parameters, rich output schema, and safety annotations, this description is complete enough for an agent to select and invoke the tool correctly. The only minor gap is explicit routing to sibling tools, which is helpful but not essential here.

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?

All four parameters are fully documented in the schema with descriptions, examples, and defaults, so schema description coverage is 100%. The description's mention of tag and author filtering adds little beyond what the schema already provides, making the baseline 3 appropriate.

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 uses a specific verb and resource ('List published blog posts') and adds topical scope ('home remodeling, renovation costs, and construction tips') plus filter capability. The plural 'posts' and 'published' framing helps distinguish it from get_blog_post, though it does not explicitly name sibling alternatives.

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 clear context for when to use the tool: listing or filtering published blog posts about home remodeling. However, it does not explicitly say when not to use it or mention alternatives such as get_blog_post for a single post or search_content for broader content search, so usage is mainly implicit rather than explicitly routed.

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