Plan Bulk Product Update

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

The description adds minimal behavioral context beyond annotations. It does not disclose that planning likely avoids immediate execution, what side effects (if any) occur, or what the tool returns. Annotations already indicate readOnlyHint=false and destructiveHint=false, but the description neither confirms nor elaborates on these.

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 extremely concise and front-loaded, with two short sentences that state the core purpose and a key detail (heterogeneous updates). No filler or redundant information.

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?

The description is inadequate for a bulk operation tool without an output schema. It does not explain the output/return value (e.g., a plan ID for use with preview/execute), any prerequisites, or relationship to sibling planning tools. The openWorldHint annotation suggests possible side effects, but the description remains silent.

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 baseline is 3. The tool description does not add any parameter semantics beyond the schema's minimal descriptions ('Store name', 'Array of product updates (max 100)', 'Response format'). It fails to explain how to structure updates or what acceptable values are beyond the enum.

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 with a specific verb ('Plan') and resource ('bulk update of multiple products'), and explicitly notes that different products can have different updates. This distinguishes it from siblings like product_update_plan (single product) and product_bulk_update_preview/execute (different phases).

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 provides no guidance on when to use this tool versus alternatives. It does not mention the preview/execute counterparts or indicate that this is a preparatory step. The only hint is the word 'Plan' and the sibling naming, which the description itself does not leverage.

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