wp_assign_menu_location

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

The description only says 'assign', giving no details about side effects (overwrites existing assignments?), idempotency, error handling, or required permissions. Without annotations, the description should provide more behavioral context.

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?

Single sentence, front-loaded, no unnecessary words.

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?

Lacks details like return value (success indicator?), error cases (invalid location slug or menu ID), and the scope of effect (does it affect all locations?). Completeness is inadequate given no output schema and no annotations.

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?

The schema already describes the parameter as a map of location slug to menu ID, which is clear. The description adds no extra meaning beyond what the schema provides. With 100% schema coverage, baseline is 3.

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 'Assign menus to theme navigation locations' clearly states the action (assign) and the resources (menus to theme navigation locations). It distinguishes from siblings like wp_list_menus or wp_create_menu_item.

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 guidance on when to use this tool versus alternatives. No mention of prerequisites or context such as needing to first create menus or list available locations.

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