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

No annotations are provided, so the description carries the full burden. It signals a mutation but never states permission requirements beyond 'Seller', whether it is a partial or full update, whether pausing is reversible, or what happens to unmentioned fields and settings.

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 front-loaded sentence: actor then action then targets, with zero wasted words. It is efficient, though terse to the point of under-specifying.

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?

A mutation tool with no annotations, no output schema, and 0% parameter coverage needs the description to do far more work. As written it omits update semantics, permissions, field-to-parameter mapping, and any return/error behavior, leaving real gaps for callers.

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 coverage is 0%, so the schema gives no per-parameter documentation. The description names price, description, reseller share and pause conceptually, but doesn't map them to the parameter names (price_minor, reseller_share_pct, active), give units/format, or mention the required listing_id.

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?

States a specific verb (change/pause) and resource (listing) plus the concrete fields it touches, and the 'Seller:' prefix scopes who it is for. It distinguishes reasonably from get_listing/create_listing, though it never names the siblings or the boundary 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?

The 'Seller:' prefix implies a role precondition for use, but there is no explicit when-to-use, when-not-to-use, or pointer to an alternative tool. The actor constraint is the only contextual guidance.

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