create_pmp_deal

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Create a new PMP deal' and does not mention permissions, idempotency, response format, or any side effects. 'Create' implies mutation, but no further transparency is offered.

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 a single, brief sentence that is undeniably concise. However, it merely restates the tool name without adding meaningful content, so it does not fully 'earn its place.' It is not verbose but is under-specified.

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 creation tool with 5 parameters, no annotations, and no output schema, the description is too sparse to provide adequate context. It doesn't explain required fields, behavior on creation, or anything beyond the most obvious statement. The sparse description leaves significant gaps for an agent invoking this tool.

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 the baseline is 3. The description adds no parameter information, but the schema already fully documents all 5 parameters with meaningful descriptions. The description's lack of additional param context is not penalized due to high schema coverage.

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 'Create a new PMP deal' uses a specific verb+resource structure that clearly identifies the operation. It distinguishes from siblings like update_pmp_deal, get_pmp_deal, and delete_pmp_deal by its explicit 'Create' action.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It simply states the action without any contextual direction, similar to the update_drive example scored as 2.

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