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

Annotations already declare the safe read-only, idempotent, closed-world profile, so the description's job is to add context — and it does: it discloses pagination behavior ('at most 50 per page') and the result shape including the four possible status values (losing, leading, alone, unknown). It does not say what the default page/limit are or whether an empty result means nothing tracked, which keeps it from a 5.

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?

A single dense sentence that front-loads the purpose and then adds the return payload, statuses, and pagination. Every clause carries information, though the sentence is long enough that a reader must parse a nested list of fields mid-way.

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?

The tool is a simple read-only, two-parameter list with no output schema, and the description covers the returned fields, the status vocabulary, and pagination limits. Only default values and result-count behavior are missing, which is minor for a read-only listing 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 0%, so the description must compensate for both parameters. It explains paging ('Paginated by page') and confirms the 50-per-page cap that matches the schema maximum, but there is no mention of defaults, of what `limit` controls when omitted, or of whether page numbering starts at 1 — leaving half the parameter semantics to inference.

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 uses a specific verb+resource ('Returns the account-wide price position summary') and enumerates the returned fields (buy box, top 1-3 counts, average rank, gap to best price, status values). It implicitly differentiates from siblings like list_tracked_products and get_account_summary by scoping to 'products that need attention', but never names an alternative explicitly.

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?

There is no explicit when-to-use or when-not-to-use guidance. The phrase 'need attention' hints at a monitoring scenario, but an agent is not told how this differs from list_tracked_products (which presumably lists all tracked products) or get_account_summary, nor when to prefer one.

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