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

No annotations are provided, so the description carries the full burden. It discloses one behavioral constraint (the first set per platform is protected), but says nothing about whether deletion is permanent, whether the tool errors or silently no-ops when handed the primary set ID, or what the response looks like.

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, no filler, with the protection rule front-loaded right after the action. Sizing is appropriate for the tool's simplicity.

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 annotations and no output schema, the definition should explain the failure mode (attempting to remove a primary set) and the severity of the deletion. Both are absent, leaving the agent to guess.

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% and the description never mentions platformSetId — not where to obtain it, not whether it must reference a non-primary set, not its format. The single parameter is left entirely to the bare schema name.

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 ('Remove an ... platform set'), which is clearly distinguishable from the add_platform_set sibling by the remove/add contrast. The qualifier 'extra' is somewhat jargon-y and never defined, which keeps it from a 5.

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 second sentence, 'The first set of each platform stays,' is an implicit precondition: you cannot remove the primary set, only extras. That is real usage guidance, but it is stated as a rule rather than an instruction about when to reach for this tool versus add_platform_set or other remove_* siblings.

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