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

Annotations already indicate this is a mutation (readOnlyHint false) and not destructive. The description adds no additional behavioral context, such as side effects, required permissions, or relationships established with the client.

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 sentence with no redundant words, effectively front-loaded. However, its brevity borders on under-specification, which slightly detracts from this dimension.

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 tool with 9 parameters, no output schema, and minimal annotations, the description is inadequate. It fails to explain the concept of an engagement, preconditions, or expected behavior, leaving significant gaps for an agent to fill.

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%, so the description fails to explain any parameter semantics beyond what the schema's names and types imply. It does not clarify fields like accounting_run_ref or sales_deal_ref, leaving the agent to guess their purpose.

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 clear action (create) and a specific resource (consulting engagement), and distinguishes it from related tools like create_consulting_client and create_consulting_deliverable. The qualifier 'owned' is ambiguous but does not obscure the primary purpose.

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, nor any conditions or exclusions. It does not mention that the client must already exist or be 'owned', nor does it point to update_consulting_engagement for modifications.

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