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

Beyond the annotations (readOnlyHint=true, destructiveHint=false), the description adds genuinely useful behavioral traits: ordering ('newest first'), pagination behavior ('Paginated'), and output shape ('compact records, no page bodies'). This tells the agent what it will and won't get back without contradicting any annotation.

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 short sentences totaling about 18 words, with zero filler. The verb and resource are front-loaded, and every clause earns its place: scope, ordering, pagination, and output-shape caveat.

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 listing tool, this is nearly complete: scope, order, pagination, and record content are all disclosed, and the annotations plus existing output schema cover safety and return structure. The only gap is not explicitly routing the agent to get_page when a page body is needed, which is a minor omission given the sibling list is visible.

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 0%, so the description must compensate. It adds the concept of pagination, which gives semantic context for limit/offset, but it does not explicitly say limit controls page size and offset controls the starting position. The compensation is partial, so a middle score is 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 states a specific verb ('List'), a resource ('the pages you have published to dochost'), and an ordering guarantee ('newest first'). It naturally distinguishes from siblings: it is a list/scoping operation, whereas get_page presumably fetches a single page, and publish/update/delete_page are mutations.

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: it is scoped to the caller's own published pages and is suitable for browsing/list operations. The 'no page bodies' note implies that content retrieval belongs elsewhere, but it never explicitly names get_page as the alternative for full bodies, so it stops short of a 5.

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