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

Annotations already declare readOnlyHint and openWorldHint, so the description adds some value by stating it returns an audited deliverable and that inputs are validated server-side. It also hints at 'agent-payable' cost implications, but doesn't elaborate on side effects, rate limits, or failure modes beyond validation.

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 short, but the opening phrase is a fragment and the reference case may be confusing rather than helpful. It is not excessively long, but the structure could be clearer with a more standard subject-verb-object format.

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?

Despite having 8 parameters, nested objects, and no output schema, the description does not explain the return format in detail, does not list required input fields, and gives only a single reference case. This is insufficient for the complexity of the 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 only 13%, and the description does not compensate. It merely says 'send the documented case fields' without enumerating or explaining any parameters, leaving the agent to rely on sparse schema metadata. The description adds essentially no semantic value for parameters.

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 clearly specifies the tool's function: it returns a structured positioning deliverable with differentiation angle, 5 messaging pillars, and battle plan. This is a specific verb-resource combination that distinguishes it from sibling tools like pricing_strategist or market_entry_strategist.

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 implies the tool should be used when a positioning strategy is needed, and 'send the documented case fields' gives a basic instruction. However, it does not explicitly contrast with alternatives or provide when-not-to-use scenarios, so it falls short of clear exclusions.

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