TDQS

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is covered. The description does add one genuine behavioral fact beyond the structured data: only *published* posts are returned. It says nothing about default page size, ordering, or empty-result behavior, which the schema only partly covers.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, scope front-loaded before the filter sentence. Minimal waste, though the second sentence largely repeats what the schema already says about tag and author.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, annotations covering the safety profile, and full schema coverage on all four optional parameters, the description is nearly complete. The only remaining gap is ordering/pagination behavior, which the offset parameter partially addresses in the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter (tag, author, limit, offset) is already documented with examples and defaults. The description merely restates that tag and author are filters, adding no syntax, matching, or combination semantics (e.g. whether filters AND together). Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('List') plus the resource ('published blog posts') and even the topical scope (home remodeling, renovation costs, construction tips). That distinguishes it from get_blog_post (single post) and list_blog_tags_and_categories, though neither sibling is named explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Filter by tag or author name' implies how to use the filters but gives no guidance on when to reach for this tool versus get_blog_post or search_content. Usage is inferable from the verb 'List' but not stated.

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