list_my_glublers

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

With no annotations provided, the description carries the behavioral disclosure burden. 'Retrieve' communicates read-only intent, and the mention of 'child subglublers and website count' adds useful detail. However, it does not disclose behavior around unauthenticated calls, pagination, output structure, or error conditions.

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 that defines the resource, states the retrieval action, and adds relevant return details without any filler. Every clause contributes meaningful information.

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 no-parameter, no-output-schema read tool, this description is largely sufficient for an agent to select and invoke it: it names the action, the scope, and key return content. It could be more complete by clarifying whether 'website count' is per Glubler or total, and by noting authentication requirements or list structure, but these are not blocking for a zero-parameter call.

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 has zero parameters, so the input schema is empty and there is little to document. The description adds value by clarifying the scope of what is returned (the authenticated user's Glublers, including subglublers and website counts), which is the only parameter-like context that matters here.

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 ('Retrieve'), a clear resource (authenticated user's Glublers), and clarifies what Glublers are with the parenthetical definition. It also distinguishes itself from siblings by scoping to the authenticated user's own collections and by mentioning subglublers and website counts, which get_public_glubler and search_glubler_catalog do not promise.

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 phrase 'authenticated user's' implies this tool is for fetching the caller's own bookmark collections, which gives some contextual guidance. However, it does not explicitly state when to use this tool versus get_public_glubler, get_glubler_details, or search_glubler_catalog, nor does it mention exclusions or alternatives.

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