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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the mutation/safety profile is covered. The description adds a genuinely useful nuance with 'Returns the number of rows actually removed,' implying partial/no-op removal when URLs were not tracked, but it says nothing about permissions, the 1800-item cap, or reversibility.

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?

Three short sentences with zero filler, and the action plus scope are front-loaded ahead of the parameter hint and return note. Nothing is redundant enough to trim.

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?

An output schema exists, so the return-count sentence is a bonus rather than a necessity, and the core destructive operation is described. However, for a destructive 2-param mutation with no schema descriptions, the definition leaves the batching limit and the handling of untracked URLs for the agent to infer.

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 0% and neither parameter has a description, so the description must compensate. It clarifies that 'urls' must be full URL strings (not paths) and that siteUrl identifies the property, but it omits the minItems=1 / maxItems=1800 bounds and required-ness context.

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+resource ('Removes URLs from the GSC Wizard Indexing Tracker') and scopes it 'for a property,' so an agent can distinguish it from get_indexing_tracker or list_tracked_urls. It does not explicitly name its inverse sibling add_tracked_urls, but 'stop tracking' makes the direction unambiguous.

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 'Pass the full URL strings to stop tracking' implies how to invoke it, but there is no explicit when-to-use vs. when-not guidance and no mention of alternatives such as add_tracked_urls or list_tracked_urls. Usage is inferable rather than stated.

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