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

With annotations present the bar is lower, and the description still adds real behavioral context the annotations cannot: the page is read in the background and takes a few minutes, so the agent should not expect an immediate result. It doesn't state permission requirements or how to observe completion.

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?

Three compact sentences, front-loaded with the effect of the call, then the mechanism, then the usage condition. No filler, though the parenthetical classification list is slightly dense.

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?

There is no output schema, and the description covers the essential unknown for an async operation: it runs in the background and takes a few minutes. It stops short of saying how the agent should verify completion (e.g. via a job or update listing), which would make it fully self-contained.

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 both parameters are already documented in the schema. The description reinforces that the URL should be a page previously shown as 'skipped' by list_existing_pages, adding modest semantic value but no new format or constraint detail.

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 concrete effect: a page Blawgy skipped is reclassified as an article so new plan ideas are checked against it. The verb+resource are clear and the meaning of 'include' is unambiguous. It does not, however, explicitly contrast itself with nearby siblings such as restore_existing_page or remove_existing_page, so an agent must infer the boundary.

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?

Gives an explicit trigger: 'Use when a skipped page really is content the plan should not duplicate,' and points to list_existing_pages kind "skipped" as the source of candidates. No exclusion or named alternative tool is given, which keeps it below a 5.

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