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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered; the description still adds real context by stating it is 'Free' (no credit spend) and by documenting the home-page default behavior that applies across the design ops. It doesn't describe the design payload structure, but that is minor for a read.

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: the first states what is returned, the second gives the one operational rule. The default-page caveat is front-loaded before the calling instruction; there is no filler.

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 single optional-parameter read with rich annotations and no output schema, the description covers the key facts an agent needs: what it returns (design plus site-live status), the home-page default, and that it costs nothing. Only the shape/size of the returned design is unspecified, which is a small residual gap.

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 100% and the schema's page_id description already explains 'Omit for the home page'. The description reinforces the default-home behavior but adds no syntax, format, or sourcing detail beyond what the schema states, so baseline 3 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?

States a specific verb ('Read') and resource ('the current design'), plus an extra return facet ('whether the site is live') and a scope qualifier (home page vs page_id). It is clearly the read counterpart to soclo_page_design_save, though it never names the sibling that would be confused with it.

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 design operations default to the HOME page, so pass page_id for any other page' gives a concrete condition for parameterizing the call and warns that omitting it targets home. It stops short of naming alternatives (e.g., save/update design ops) or stating when not to call it.

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