delete_library_sections_by_section_id_intros

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

Annotations already declare destructiveHint=true and idempotentHint=true, and the description's 'Delete' is consistent with those. However, the description adds no behavioral detail beyond the annotations—it does not say whether markers are permanently removed, whether the operation is reversible, or what side effects occur.

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 short and front-loaded: action first, then endpoint, then args. It has no filler, though the endpoint line is somewhat redundant with the tool name.

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 one-parameter delete operation with an output schema and clear annotations, the core call signature is documented. But the agent still lacks context on when intro markers apply and what the destructive operation entails, which matters given the destructiveHint annotation.

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?

With 0% schema description coverage, the description carries the burden, and it does list section_id as 'Section identifier.' This is minimal but confirms the argument's role, and the endpoint path also shows {sectionId} substitution. It adds only modest meaning over the schema's title and type.

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 opens with 'Delete section intro markers,' naming the verb and the specific resource, and the DELETE endpoint reinforces the action. It is clearly distinct from sibling tools that target the whole section or other sub-resources, though it does not explicitly clarify what an 'intro marker' is or position itself against siblings.

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 guidance on when to use this tool versus the many sibling delete tools, such as delete_library_sections_by_section_id or delete_library_metadata_by_ids_marker_by_marker. The description states only what the endpoint does, leaving the agent to infer the appropriate use case from the name.

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