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

No annotations are provided, so the description carries the full behavioral burden. It never confirms this is a read-only operation, says nothing about result ordering, pagination, or the effect of 'limit', and gives no indication of what the returned results contain.

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 sentences, zero filler, with the default-scope behavior front-loaded before the override. Nothing redundant.

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?

With no annotations and no output schema, the description should cover the return shape and the meaning of site_id/limit, but it stops at content_kind. It is adequate to make a correct call in the common case but leaves real gaps for a 4-parameter tool.

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 only 25%, so the description must compensate and it does partially: it explains the content_kind enum values and their default, and clarifies that query matches title/focus keyword. site_id and limit remain unexplained in both schema and description.

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+resource ('Search a site's articles') and scopes the search field to title / focus keyword, which is concrete. It does not explicitly contrast itself with Browse_Articles or Read_Article, so the sibling differentiation is left to inference.

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 routing among content kinds (blog default, 'help' for KB, 'all' for both), which is genuinely useful. However it offers no guidance on when to search versus browsing/reading a known article, which is the more important sibling decision among these 15 tools.

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