Rename board section

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the mutation and safety profile is covered. The description adds the required OAuth scope (boards:write), a genuinely useful behavioral detail not present in annotations, but says nothing about what the rename affects or whether the section must already exist.

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 with the action stated first and the scope constraint second; no filler or redundancy.

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 annotations present and no output schema, the description covers the action and permission scope but leaves the required identifiers and the business-account ad_account_id nuance entirely to the schema. It is minimally adequate rather than complete.

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 only 50% - name and ad_account_id are documented in the schema, while board_id and section_id carry no description anywhere. "Rename" loosely implies name is the target value, but the description adds no semantics beyond the schema and does not compensate for the two undocumented identifier parameters.

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 gives a specific verb (rename) and resource (existing board section), which clearly separates it from create_board_section and delete_board_section. However, it does not name or contrast any sibling tool explicitly, 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?

"Scope: boards:write" implies the prerequisite permission, which gives the agent a usable gating condition. There is no explicit when-to-use guidance or comparison against alternatives such as pinterest_update_board or pinterest_create_board_section, so usage is only implied.

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