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

Annotations only flag destructiveHint=true, whereas the description adds the two facts an agent actually needs: the deletion hits the LIVE public page and is permanent/irreversible. That is real added context beyond the annotation, though it still says nothing about auth requirements, error behavior, or whether related update records are cascaded.

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?

One sentence, front-loaded with the ALL-CAPS verb and the consequence, then the API route. The redundancy between 'DELETES' and 'permanently removes it' is defensible emphasis for a destructive operation, but it is still two clauses making the same point.

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 2-parameter, no-output-schema destructive tool, the description plus the destructiveHint annotation cover the essential decision inputs: what is destroyed and that it is irreversible. Remaining gaps (side effects on incident updates, failure modes) are minor and typical for a CRUD delete.

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 100% — both subdomain (with its STATUSPAL_SUBDOMAIN override semantics) and incident_id are documented there. The description's endpoint path merely mirrors those parameters without adding format, range, or lookup guidance, 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 (DELETE) and resource (incident) and names the exact surface affected — the LIVE public status page — plus the underlying API route. It is immediately distinguishable from the create/update/get/list siblings that operate on the same resource.

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?

Deleting is self-evidently the tool's job, so usage is implied, but there is no explicit guidance on when to reach for it versus statuspal_update_incident, nor any prerequisite (permissions, confirming the incident is not scheduled/resolved) or warning about what happens to linked incident updates.

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