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

Annotations already declare destructiveHint=true, readOnlyHint=false and idempotentHint=true, so the safety profile is covered. The description adds beyond the structured data by flagging 'WRITE: requires the ADMIN role,' an authorization prerequisite not encoded anywhere else, though it says nothing about reversibility or failure behavior.

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?

Two short sentences: the effect first, the operational constraint second. Every clause earns its place with no filler or restatement of the title.

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 one-parameter delete with full schema coverage and annotations carrying the destructive/idempotent profile, the description covers what matters: the semantic effect of removal and the ADMIN requirement. No output schema exists and none is implied, so remaining omissions (error cases, confirmation flow) are minor.

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% for the single id parameter, and its schema description already explains format (UUID) and provenance (from create_ignore_rule or list_ignore_rules). The description contributes nothing further about the parameter, so the baseline 3 applies.

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 (Remove) and resource (ignore rule) and, unusually, the functional consequence: the fingerprint counts toward burn-rate alerts again. That lets an agent distinguish it from create_ignore_rule/list_ignore_rules and sibling deletes like delete_alert_rule without opening a 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?

The stated effect implies the usage context (undo a suppression so alerting resumes), but there are no explicit when-to-use/when-not conditions and no named alternatives such as list_ignore_rules for finding the id or suppress_signal for temporary suppression. Usage is inferable but not spelled out.

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