Increment inventory amount

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

The description states it increments by one and returns the new amount, but with no annotations provided, it could mention error behavior (e.g., if item does not exist) or permission requirements. The endpoint is given, adding some transparency.

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 two sentences: first explains the action and return value, second gives the endpoint. Each sentence is necessary and succinct.

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 single-parameter tool with no output schema, the description is fairly complete: it tells what it does, the effect, return value, and endpoint. It could mention error cases or prerequisites, but overall adequate.

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 3. The description does not add extra meaning beyond the schema's parameter description ('The inventory item ID.'). No additional format or usage details are provided.

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 action: increment inventory amount by one, and specifies it returns the new amount. This distinguishes it from the sibling tool 'hortusfox_decrement_inventory_item' by naming the operation.

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?

While the name and description imply when to use this tool (to increase count), there is no explicit guidance on when to use it versus alternatives, nor any exclusion context. The sibling tool 'decrement_inventory_item' is the obvious alternative, but not mentioned.

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