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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so safety is largely covered. The description adds real behavioral value by clarifying blast radius: tools are only hidden from tools/list and remain callable via call_tool/call_write_tool, which answers the main agent worry about breaking access.

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 tight sentences, front-loaded with the action and its effect, with no filler. Every clause carries information.

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 one-parameter, no-output-schema tool the description covers the action, its scope, and the recovery path for affected tools. The remaining gap - how to obtain valid pack names - is real but narrow.

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?

The single parameter has 0% schema description coverage, so the description must compensate, but it never explains what a 'pack' identifier is, its format, or where to discover valid values (e.g., via list_packs). The array-of-strings input is left semantically opaque.

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 (remove) plus resource (packs) and, crucially, the non-obvious scope of the effect: removal from tools/list for this connection. This lets an agent distinguish it from enable_packs/list_packs without opening any 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?

The rationale ('to keep the list short') implies when to use it, but there is no explicit when-to-use or when-not-to-use guidance and no mention of the inverse sibling enable_packs. Usage must be inferred from the purpose statement.

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