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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful behavioral context beyond that: results mirror the editor's Page Settings screen, and 'Defaults are named as defaults' tells the agent how unset values will be represented in the response.

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?

A single front-loaded sentence with the verb and resource first, followed by a useful field enumeration. The long em-dash list is dense but every element names a distinct setting category, so it earns its length; it stops just short of being over-stuffed.

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 output schema, the description does the heavy lifting by enumerating the returned settings fields, which is exactly what an agent needs to plan a read. The one real omission is any semantic guidance on projectId, the required parameter.

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 coverage is 50%: pageName is documented ('One page; omit for all.') but projectId has no description. The description's phrase 'each page's' reinforces the all-pages default but adds nothing about projectId, so it neither compensates for the gap nor falls below the baseline for partially-covered schemas.

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 (read) and resource (each page's Settings) and enumerates the exact fields returned (slug, meta title/description, social image, canonical URL, language, indexing, AI crawlers, custom code). This separates it cleanly from siblings like uichemy_get_page (page content), uichemy_get_page_code, and uichemy_set_page_settings (the write counterpart).

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?

Usage is only implied: 'Read each page's Settings' suggests inspection, and the schema's 'omit for all' hints at the all-pages case. There is no explicit statement of when to prefer this over uichemy_get_page or uichemy_set_page_settings, nor any prerequisites or exclusions.

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