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

With no annotations provided, description carries full burden. It discloses return fields (SKU, name, quantity, location, category) and auth requirement (API key), but omits safety profile (read-only vs destructive), rate limits, or empty result behavior.

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?

Three short sentences with zero waste. Front-loaded with the core action (Search inventory items), followed by return values and requirements. Every clause earns its place.

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 4-parameter search tool with no output schema, the description adequately covers the return payload structure by listing fields. However, it should clarify that all parameters are optional (required: 0) and elaborate on pagination behavior given the page/limit parameters.

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%, establishing baseline 3. Description mentions 'filters' which loosely references the category parameter, but adds no syntax details, format examples, or semantic relationships between parameters beyond what the schema already provides.

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 specific verb (Search) + resource (inventory items) + method (with filters). Distinguishes from 'lookup_sku' sibling by implying broader filtering capability, though it doesn't explicitly name the sibling.

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?

Provides no guidance on when to use this tool versus alternatives like 'lookup_sku' (for specific SKU retrieval) or 'check_stock_levels' (for quantity-focused queries). No prerequisites or exclusions mentioned beyond API key.

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