update_collection

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

Annotations provide only openWorldHint=true, so the description carries most of the behavioral burden. It helpfully discloses that the name is transmitted upstream as the collection title and that edits to a synced collection flag it for re-sync, which is genuine side-effect information. It does not address permissions, whether removal of name/description is possible, or reversibility, leaving meaningful gaps for a mutation.

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 front-loaded, efficient sentences convey the core action and side effects with no filler. However, the trailing artifact '[#1d73cf]' is stray noise that does not belong in a tool description and slightly undermines structure.

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 5-parameter mutation with no output schema and minimal annotations, the description covers the core action and one important side effect but leaves required identifiers and the workspace parameter unexplained. It is adequate to attempt a call but not complete enough to anticipate edge cases like synced-collection behavior on other fields.

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 0% and the description only illuminates 2 of the 5 parameters (name, description), while store_uuid, collection_uuid, and workspace receive no explanation anywhere. The note that name maps to the platform 'collection title' is valuable, but the selector parameters an agent must supply are undocumented.

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 specific verb and resource with scope: 'Update a collection's name and/or description.' An agent can distinguish this from create_collection, delete_collection, and update_product on name alone. It stops short of explicitly differentiating from near-neighbors like sync_collection or add_products_to_collection.

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, no preconditions, and no named alternatives despite many plausible ones (sync_collection, add_products_to_collection, update_store_settings). The one contextual note — that editing a synced collection marks it for re-sync — describes a consequence rather than routing guidance.

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