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 elsewhere. The description adds only 'after MCP confirmation', which is undefined jargon, and omits what actually matters for a delete: whether removal is reversible, whether it cascades to dashboard contents, and how idempotency_key affects retries.

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?

A single front-loaded sentence with no filler, and the destructive verb leads. It is efficient, though the brevity tips into under-specification rather than crispness.

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, non-open-world tool with no output schema and three undocumented required parameters, the definition is too thin. Critical details — confirmation mechanics, reversibility, and idempotent-retry behavior — are missing entirely.

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% across three required parameters, so the description carries the full burden and fails: workspace, page_key, and idempotency_key are never mentioned or explained. An agent cannot learn from this text what page_key identifies or that idempotency_key makes retries safe.

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 ('custom dashboards'), which maps to the layouts_* family and separates it from layouts_get and layouts_update. It stops short of naming those siblings explicitly, so differentiation relies on the reader inferring it.

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?

'after MCP confirmation' hints at a prerequisite gate, but the description never says when to choose this over layouts_update or what conditions must hold before deletion. No exclusions, no alternatives, no prerequisites beyond the vague confirmation phrase.

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