Toggle Memcached

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

With no annotations, the description bears full responsibility for disclosing behavioral traits, but it only states 'toggle on/off.' It omits side effects (e.g., cache flush, reversibility), permission requirements, or what happens to existing state. This is thin for a mutating operation.

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 a single, front-loaded sentence with no filler. Every word contributes to conveying the action and target, making it highly concise and easy to parse.

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?

Despite being a simple toggle, the description lacks essential context: it does not mention return values, prerequisites (e.g., Memcached installed), or the relationship to the sibling wp_memcached_status. An agent would not know what to expect or how this fits into the workflow.

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 100%: both parameters have descriptions, so the baseline is 3. The tool description adds no parameter-level detail beyond the schema, so no higher score is justified.

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 uses a specific verb ('Toggle') and a clear resource ('Memcached object cache'), making the tool's purpose unambiguous. It distinguishes this tool from related siblings such as wp_memcached_status (status check) and hosting_cache_toggle (general cache toggle).

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 is provided on when to use this tool versus alternatives. It does not mention related tools like wp_memcached_status or clarify scenarios where toggling is appropriate, leaving the agent without decision support.

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