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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered; the description adds the genuinely useful scoping fact that analytics data survives. It does not mention that idempotentHint=false (a retry after a partial failure behaves differently) or any reversibility/permission details, which are relevant for a destructive call.

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 sentences, no filler, and the scope limit is stated in one clause. The one structural weakness is that it opens on a parameter instruction ("Pass confirm:true") before establishing what the tool actually does, so the action statement is not front-loaded.

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 destructive three-required-parameter tool with no output schema and thin schema coverage, the definition covers the confirm gate and the blast-radius boundary but omits how a viewId is obtained, whether the deletion is recoverable, and whether the confirm gate is the only guard needed. Adequate, not complete.

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 only 33% — viewId and confirm carry no schema descriptions — so the description must compensate. It does explain confirm as a literal true gate, but viewId is left entirely unexplained; the reader must infer it is the saved dashboard configuration identifier from the sentence about deletion.

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: deleting a saved dashboard configuration scoped to the authorized workspace. That separates it cleanly from save_dashboard_view and get_dashboard_views. It stops short of naming those siblings explicitly, which keeps it from a 5.

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?

Implies the deletion use case and prescribes the confirm:true ritual, but says nothing about when to prefer this over alternatives, whether the caller should obtain user confirmation first, or how to discover a viewId (get_dashboard_views exists as a sibling for that). Usage is inferable rather than guided.

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