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

Annotations already declare destructiveHint=true and openWorldHint=true, and the description adds genuinely useful behavior beyond them: the live site stops redirecting without a publish, usually within minutes. That timing and no-publish effect is exactly the operational context a destructive tool needs. It stops short of stating whether the deletion is recoverable or what permissions are required.

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 with zero waste; the action comes first and the behavioral consequence follows. Every clause earns its place.

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 two-param destructive call with no output schema and annotations already covering the safety profile, the description supplies the missing piece (immediate unpublish-free effect). Only the reversibility/permission story is absent, a minor gap against the otherwise complete picture.

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 UUID params are documented), so the schema carries the parameter burden. The description adds no syntax, format, or scoping detail beyond it, which is the expected baseline when coverage is complete.

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 ('Delete a URL redirect') that unambiguously separates it from create_redirect, update_redirect, and list_redirects. An agent knows exactly what object is being acted on without 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?

No when-to-use or when-not-to-use guidance is given, and no alternative is named (e.g., update_redirect to disable rather than remove). The single-target delete is implied by the verb, but nothing addresses the delete-vs-modify decision an agent actually faces.

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