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

No annotations are provided, so the description carries the full burden, and it delivers the crucial behavioral fact that this creates a persistent ignore rule that suppresses the issue on future crawls rather than a one-off dismissal. It also flags the precondition that only alerts naming a URL can use target_pattern. It does not disclose permissions, idempotency, or how to reverse the rule (only implicit via the unignore_alert sibling).

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?

Front-loads the essential instruction and the mandatory user-consult rule before the scope taxonomy, which is the right ordering. The scope explanations are dense but each clause adds discriminating information; only the parenthetical examples of alert types are slightly padded.

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 4-parameter mutation tool with no annotations and no output schema, the description covers purpose, scoping semantics, persistence side effects, and a hard user-consultation requirement. Remaining gaps are error/conflict behavior and the reversal path, which are minor given the sibling unignore_alert exists.

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 coverage is 100%, so baseline would be 3, but the description adds real semantic distinction between route_pattern (glob over the PAGE the issue was found on) and target_pattern (glob over the URL the issue is ABOUT, wherever it is linked from) with concrete examples. This disambiguates the two easily-confused enum branches beyond what the schema alone conveys.

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 ('Ignore an alert') and immediately qualifies it with the required scope dimension. It is trivially distinguishable from the sibling unignore_alert, and the four scope values are enumerated inline so an agent knows the shape of the call before opening the schema.

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?

Explicitly instructs 'ALWAYS ask the user which scope they want before calling' and then explains the discriminating condition for each of the four scopes (page URL vs issue type vs glob over page vs glob over the target URL). No alternative is left to inference.

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