catalog_item_edit

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

No annotations are provided, so the description carries the full behavioral burden. 'Partial update' hints at merge semantics but says nothing about permissions/auth (only the apiKey param hints at this), whether changes are reversible, what happens to omitted fields, or any rate limits.

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?

A single short sentence that is front-loaded with the core verb and resource. It is efficient, though arguably under-specified rather than optimally concise.

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 mutation tool with no annotations, no output schema, a nested free-form item_data object, and several confusingly similar siblings, this one-line description leaves far too much unspecified for an agent to call it confidently.

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% and every parameter (apiKey, item_id, item_data, catalog_name, restEndpoint) is documented in the schema. The description adds no syntax or format detail beyond that, so the baseline of 3 applies.

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 a clear verb+resource ('Edit a single catalog item') and adds scope via '(partial update)'. However, the sibling set contains catalog_items_edit, catalog_item_update, catalog_items_update and catalog_items_create, and the description offers no way to distinguish catalog_item_edit from these near-identical tools.

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?

There is no when-to-use guidance and no mention of alternatives, which is a real gap given several sibling tools appear to perform overlapping edits/updates. The agent must guess between catalog_item_edit, catalog_items_edit and catalog_item_update.

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