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

The annotations already communicate that this is a safe, non-destructive read operation. The description adds the price-range concept but does not disclose additional behavioral details such as result ordering, inclusive/exclusive boundaries, or pagination. It does not contradict the annotations.

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 one compact sentence that starts with the action and immediately specifies the resource and filter. There is no wasted text, filler, or redundant restatement of the tool name.

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 simple read-only price-filtered getter, the description plus the fully documented input schema is largely sufficient. It doesn't describe the exact return shape or sorting, but 'deals' as the return concept is clear enough, and the annotations cover the safety profile.

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 100%, so the baseline is 3. The description mentions INR, which aligns with the schema's 'in INR' explanations for min_price and max_price, but it adds no new meaning beyond what the schema already provides for the three 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 states the verb ('Get'), the resource ('deals'), and the specific scope ('within a price range in Indian Rupees'). It distinguishes this tool from sibling deal getters like get_deals_by_category, get_deals_by_store, and get_trending_deals by its price-based filtering focus.

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?

Usage is implied by the description: use this tool when the user wants deals filtered by a minimum and maximum price in INR. However, it does not explicitly mention when not to use it or name any alternative tools, so the guidance is indirect rather than explicit.

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