+]v2.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, and it discloses almost nothing beyond the read implication of 'Get' — no note on whether content is returned summarized or full, what happens for an invalid/nonexistent ID, or any permission requirement. The 'content' flag's effect is left entirely to the schema.
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?
A single four-word sentence with zero filler and the key qualifier ('by ID') front-loaded. It is efficient, though its brevity edges toward under-specification rather than genuine tightness.
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?
With no annotations and no output schema, the description should explain what a retrieved post contains and any notable behavior; instead it says nothing about the return shape or the post types supported. An agent knows the input but not what it will receive.
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% with three documented parameters, so the baseline is 3. 'By ID' maps to the required id parameter but adds no format or constraint detail beyond what the schema already states.
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?
States a specific verb and resource ('Get a single post') and adds the lookup key ('by ID'), so the operation is unambiguous. It does not distinguish itself from near-siblings such as wp_get_page or acf_get_post_fields, so an agent still has to infer which retrieval tool applies.
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 versus wp_list_posts, wp_search_posts, or wp_get_page, and no prerequisites (site scoping, permissions) are mentioned. Usage is only implied by the verb.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
