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

With no annotations provided, the description carries the behavioral disclosure burden. It clearly indicates this is a read/retrieval operation ('Get') and spells out the response contents in detail, including export links and auth mode. It also discloses the authorization requirement ('No adminKey needed'). It does not explicitly state that no mutation occurs, but the content and framing make that sufficiently clear.

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 description is compact and front-loaded, with the core purpose stated first, followed by a detailed list of return contents, then a concise note about authorization and a practical example. Every sentence earns its place and 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-parameter, no-output-schema tool, the description fully explains what the agent will get back: resources, counts, URLs, routes, auth mode, and export links. It also covers access requirements and gives a concrete suggested value. Nothing essential is missing.

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 100%, so the schema already documents the single 'project' parameter as the project id. The description adds the useful example of 'demo' as a public playground, but does not substantially extend parameter meaning beyond the schema.

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 opens with a specific verb and resource ('Get a project's public root index') and then enumerates exactly what that index contains: resources with record counts and URLs, custom routes, auth mode, and export links. It clearly distinguishes itself from sibling mutation tools like create_project/delete_project by stating no adminKey is needed and emphasizing the public, informational nature.

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 for when this tool is appropriate: it is a public, read-only operation requiring no adminKey, which implicitly contrasts with admin-requiring sibling tools. The suggestion to 'Try project demo for the shared public playground' provides a concrete usage example, though it does not explicitly name alternatives or state when not to use it.

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