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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=false, so the safety profile is covered. The description adds one genuinely useful behavioral detail beyond that: removal is partial ('the number of rows actually removed'), implying some URLs may fail. It does not disclose reversibility, permission requirements, or batch-size constraints.

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, each earning its place: purpose, how to call it, and return semantics. Purpose is front-loaded 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?

With annotations covering the destructive/read-only profile and an output schema covering the return shape, the description needs only to state purpose and input intent, which it does. Minor gaps: the max-1800 batch limit and the assumption that URLs are already tracked are unstated.

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%, so the description must compensate. It clarifies the 'urls' parameter meaningfully ('full URL strings'), which the bare array-of-strings schema does not, but leaves 'siteUrl' undefined and never mentions the 1800-item cap or the min-1 array constraint.

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 and resource ('Removes URLs from the GSC Wizard Indexing Tracker for a property') and clarifies intent ('to stop tracking'), so the agent knows exactly what it does. It does not name or contrast with the obvious sibling add_tracked_urls/list_tracked_urls, so sibling differentiation is left implicit.

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?

'Pass the full URL strings to stop tracking' gives a concrete usage cue, and 'for a property' implies the siteUrl scope. There is no statement of when to prefer this over list_tracked_urls or get_indexing_tracker, and no prerequisites (e.g. URLs must currently be tracked), so guidance remains implied rather than explicit.

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