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 adds useful context about verified SA retailer prices, exclusions, and the WhatsApp link return value. However, it ambiguously says 'Submit a price match claim' yet returns a pre-filled link, leaving unclear whether any backend submission actually occurs. This side-effect ambiguity is a notable gap.

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 three sentences, front-loaded with the action, and structured with exclusions and requirements in a clear, non-redundant way. There is no waste; every sentence contributes to understanding.

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 8 parameters, no output schema, and no annotations, this description covers purpose, thresholds, exclusions, required parameters, and return value. The main gap is the unstated side-effect semantics (actual claim submission vs. link generation), but overall it is fairly complete for the complexity involved.

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 100%, so baseline is 3. The description adds meaning beyond the schema by explaining that product, dimensions, and specs must be identical, indirectly guiding which parameters (width_mm, height_mm, product_id) are essential for a valid claim. It also clarifies the competitor_price_zar must be from a verified SA retailer.

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 states the tool's function: submitting a price match claim when a customer finds the same blind cheaper elsewhere. It includes specific conditions (identical product, dimensions, specs) and exclusions, making it fully distinguishable from siblings like get_price or get_whatsapp_handoff.

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 explicitly states when to use the tool ('when the customer has found the same blind cheaper elsewhere') and provides clear non-applicable cases (Blinds Direct, clearance/flash-sale, out-of-stock). It also specifies minimum required inputs (product_id and competitor_price_zar), giving actionable guidance.

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