Workbooks Update Workbook Bookmark

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

Annotations already declare it non-read-only, non-destructive, and open-world, so the safety profile is covered. The description adds that the body is a partial-editable set of fields, but says nothing about permissions, whether omitted fields are preserved, or what happens to the previous default when isDefault is set.

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, front-loaded with the action, second sentence covering body consumption and the ID-prerequisite. Nothing redundant with the title or schema.

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?

An output schema exists so return values need no explanation, and annotations cover the safety profile. Combined with the field enumeration for the opaque body, this is nearly complete; only a note on partial-update semantics for the body is missing.

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 coverage is 0% and body is an untyped open object, so the description carries the load by naming the updatable fields (name, isShared, isDefault, exploreKey). workbook_id and bookmark_id are only implicitly covered (bookmark_id via the list-tool pointer), which keeps this from a 5.

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+resource ("Update a saved view (bookmark) in a workbook") and even glosses what a bookmark is, which removes ambiguity against the many workbook siblings. It does not explicitly disambiguate from add/delete bookmark siblings, but the verb already does that implicitly.

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?

Explicitly tells the agent to retrieve bookmark IDs via workbooks_list_workbook_bookmarks, which is the real prerequisite for this call. No when-not-to-use guidance, but the context is clear.

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