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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the 'visible' qualifier, hinting results are authorization-filtered, but says nothing about scope limits, defaults, or how the supplier/product rows relate. Modest added value over 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?

Two short sentences, purpose first then usage, with no redundant filler. It is appropriately sized, though the second sentence is doing double duty for both purpose and routing without resolving either fully.

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?

With an output schema present, return values need not be explained, and the schema fully documents both parameters. Annotations cover the safety profile. The remaining gap is that zero required parameters means the tool can be called with no arguments, and the description never clarifies the default/no-entity behavior.

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 both parameters are fully documented in the schema and the baseline is 3. The description does not add syntax, format, or default behavior for entity_name or include_stock_value beyond what the schema already states (it only echoes the inventory-capital framing for include_stock_value).

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 gives a verb (Read) and resources (supplier information and product rows), but the name/title promise 'constraints' while the body talks about general supplier info and product rows, creating a mismatch. It does not distinguish this tool from sibling find_supplier, which an agent would plausibly choose instead.

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?

'Use for supplier range, constraints, or inventory-capital questions' gives implied usage triggers, which is better than nothing. But it names no alternatives and no exclusions, so the agent gets no routing help against siblings like find_supplier, compare_supplier_offer_history, or get_inventory_position that also touch supplier/inventory questions.

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