wp_cache_warm

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

With no annotations, the description carries full burden but only provides a vague action ('pre-warm'). It does not disclose whether the operation is safe (idempotent), what 'essential data' entails, or any potential side effects (e.g., load impact).

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 sentence with no fluff. It front-loads the core purpose without unnecessary words, achieving high conciseness.

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?

Given no output schema and one optional parameter, the description is minimally adequate. However, it does not explain what 'essential data' means, whether the cache is site-wide or tailored, or if this is a one-time or recurring operation.

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 only parameter 'site' is already described in the schema (100% coverage). The description adds no additional meaning beyond what the schema provides, so baseline score of 3 is appropriate.

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 clearly states the verb 'Pre-warm' and resource 'cache with essential WordPress data'. It effectively distinguishes from sibling tools like wp_cache_clear (which clears cache) and wp_cache_info (which reports info).

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 vs alternatives such as wp_cache_clear or wp_cache_stats. The description lacks context on prerequisites, timings (e.g., after content updates), or when cache warming is beneficial.

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