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

With no annotations provided, the description carries the full behavioral burden, and it does so thoroughly. It discloses that the edit_key is shown exactly once, cannot be recovered, and that losing it permanently prevents editing or deleting the page. It also explains image behavior (embedded, never hosted) and that content is Markdown, giving the agent essential side-effect and constraint knowledge.

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 three focused sentences with no filler. The purpose and return values are front-loaded, followed by content format details and the critical edit_key warning. Every sentence earns its place.

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 a simple two-parameter tool with no output schema, the description covers return values, parameter format, and the most important operational caveat (edit_key irrecoverability). An agent has enough information to invoke it correctly and understand the consequences.

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 coverage is 100%, so the baseline is 3, but the description adds meaningful detail beyond the schema. It expands the content parameter with the full Markdown feature set and image embedding behavior, while the schema already documents that the title-derived URL never changes.

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 states a specific verb ('Publish') and resource ('a new text post'), and lists the concrete return values (slug, public URL, edit_key). This clearly distinguishes create_page from its siblings delete_page, get_page, and update_page without needing to inspect them.

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 clearly frames this as the tool for publishing new text posts, which tells an agent when to use it. It does not explicitly name sibling tools or say 'use update_page to modify an existing page,' but the context is clear enough that an agent can route correctly.

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