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

Annotations already flag destructiveHint=true and idempotentHint=true, and the description goes further: it discloses that the pack file is deleted, the change is deferred to the next restart, and the world survives (with a possible reset suggestion). That is meaningful consequence information beyond the structured hints.

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 waste, with the action and its effect front-loaded before the caveat about the world reset. Everything present 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 destructive one-parameter tool with no output schema, the description covers the essentials: what is removed, when it applies, and what is preserved. Only the parameter itself and any permission/state requirements are left unaddressed.

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 reported at 0% and the description never mentions the single `path.serverId` parameter. It only implies server scoping via 'the server's uploaded custom modpack,' so it does not compensate for the coverage gap.

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?

The description states a specific verb and resource: 'Uninstalls the server's uploaded custom modpack and deletes the file.' That is unambiguous and distinguishable from siblings like deleteAsset or deleteBackup, though it never names an alternative to route the agent away from.

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 context is only implied through 'taking effect at the next restart,' which hints at timing but says nothing about preconditions or when to choose this over resetServer or updateServer. No exclusions or prerequisites are stated.

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