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

No annotations are provided, so the description carries the full burden. It discloses that this is a mutation tool ('Update'), but doesn't mention behavioral traits like permission requirements, whether changes are reversible, rate limits, or what happens to unspecified fields. The partial update guidance is helpful but insufficient for a mutation tool without annotations.

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 two sentences, front-loaded with the core purpose and followed by a key usage constraint. Every word earns its place with zero waste, making it highly efficient 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?

Given no annotations and no output schema, the description is adequate for a basic update tool but lacks completeness. It covers the purpose and partial update behavior but misses critical context like error handling, response format, or side effects. For a mutation tool with 6 parameters, more behavioral disclosure would be beneficial.

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%, so the schema already documents all parameters thoroughly. The description adds minimal value by listing the updatable fields, which mirrors the schema properties. It provides the partial update constraint ('Only provide the fields you want to change'), which is useful but doesn't significantly enhance parameter understanding beyond the schema.

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 action ('Update') and resource ('post/page'), and lists specific fields that can be modified (title, content, excerpt, status, slug). It distinguishes from siblings like 'create_page' by focusing on updates rather than creation. However, it doesn't explicitly differentiate from other update tools like 'update_element' or 'update_seo_data'.

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?

The description provides implied usage guidance by stating 'Only provide the fields you want to change,' which suggests a partial update pattern. However, it doesn't explicitly state when to use this tool versus alternatives like 'update_element' or 'update_seo_data,' nor does it mention prerequisites such as needing an existing post ID.

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