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

The annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the description need not repeat safety. It does add genuinely useful context beyond them: the creator must have connected their Piku account, and the read returns an 'open Page draft' alongside published state. It stops short of describing pagination or size limits, which matters less for a single-page 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?

The permission/identity constraint is front-loaded in the first sentence, which is the right ordering. The second sentence is a long comma-spliced enumeration of returned fields; it earns its length by standing in for a missing output schema, though it could be structured as a list for faster scanning.

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 must convey what comes back, and it does so concretely across page settings, tabs, links, widgets, Rates, groups, Portfolio and drafts. For a zero-parameter read tool this is close to complete, with only the response shape (single object vs nested arrays) left implicit.

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?

The tool takes no parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The field enumeration is better read as return-value documentation than as parameter meaning.

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 names a specific verb and resource ('The connected creator's public page as data') and enumerates the returned content, so the purpose is unmistakable. It does not explicitly contrast with siblings such as design_page or list_page_drafts, so it falls short of a 5.

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?

It states the prerequisite audience and auth condition ('Creators only, on their own Piku account (asks them to connect)'), implying when the tool is available. However, it never says when to call this versus design_page (which presumably mutates the same page) or list_page_drafts, leaving the agent to infer selection.

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