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

With no annotations, the description carries the full burden. It discloses key behaviors: provider-agnostic removal, no error on missing background, optional request body, top-level parameter convention, camelCase/snake_case aliases, and authentication. It stops short of stating response codes or impact beyond background removal, but the disclosed details are substantial.

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?

The description is compact and front-loaded. The first sentence states the core action, followed by four short sentences that each add useful context about edge cases, request body, parameter conventions, and auth. No redundant or irrelevant 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 single-parameter endpoint with no output schema or annotations, the description covers the operation thoroughly: what it does, its edge case, request body, parameter style, and auth. It could mention expected response status or irreversibility, but given the tool's narrow scope and the proxy framing, the existing context is largely sufficient.

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 input schema describes the parameter as 'Project ID Required' but lacks detail on how it should be passed. The description adds that path/query parameters are top-level fields and that original parameter names accept camelCase/snake_case aliases, clarifying invocation format. Given schema coverage is 100%, the description provides incremental value.

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 opens with a specific verb+resource: 'Remove a project background.' It explicitly identifies the REST proxy target 'DELETE /projects/{id}/background', distinguishing it from other project deletion variants. This unambiguously conveys the tool's scope.

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 description clearly indicates when to use this tool: whenever a project background needs removal. It adds context about idempotent behavior ('does not throw an error if the project does not have a background') and authentication requirements. However, it does not explicitly discuss alternative tools for other delete operations or provide exclusion criteria.

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