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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered without the description. The description adds useful semantics (lineage = upstream sources and dependencies), clarifying what the result means, but says nothing about lineage depth, traversal direction beyond 'upstream', or freshness, which would be valuable given openWorldHint.

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 front-loaded sentence with the resource and its parenthetical definition; nothing extraneous.

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 needn't be explained. However, for a two-parameter lookup with zero schema documentation, the description leaves the agent without ID expectations or a clear routing rule against the many lineage-related siblings.

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%, with both workbook_id and element_id undocumented in the schema. The description only implies 'one workbook element' and offers no ID format, source-of-ID, or scoping guidance to compensate for the coverage gap.

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 ('List the lineage') scoped to one workbook element, and parenthetically defines lineage as upstream sources and dependencies, which an agent can use to distinguish it from workbook-level lineage tools. It doesn't explicitly name the sibling it is not (e.g., workbooks_list_workbook_lineage), so it stops short of full differentiation.

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?

No statement of when to use this element-level lineage tool versus workbook-level or data-model-level lineage siblings, and no prerequisites or exclusions. The scope 'one workbook element' only weakly implies usage.

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