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

Annotations only declare destructiveHint=true; the description adds the API endpoint and the directional note that enabling protection is the safest write, which partially compensates. However it omits that turning protection OFF is the destructive direction, whether the change takes effect immediately, and any permission requirements.

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, front-loaded with the operation and followed by the endpoint reference. Nothing is wasted, though the 'safest write' aside is more editorial than informational.

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?

A mutation tool with no output schema and minimal annotations; the description covers what changes but not the resulting state, error conditions, or whether protection changes are reversible. Adequate but leaves behavioral gaps for a write operation.

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%, so delete, rebuild, and server_id are already documented in the schema. The description adds no format or default guidance beyond restating that protection can be turned on or off, 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 (turn on/off) applied to a specific resource (deletion and rebuild protection for a server), naming both toggled flags. An agent can distinguish this from siblings like enable_server_backup 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?

Usage is implied by the resource name, but there is no explicit when-to-use guidance, no prerequisites, and no reference to related tools (e.g. rebuild or delete actions) that this protection gates. The claim that ON is 'the safest write' hints at intent without stating a selection rule.

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