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

Adds real behavioral context beyond annotations: the removal only affects duplicate detection ('It stops counting when the plan checks for duplicates') and explicitly does not touch the live website, which reconciles with destructiveHint=false. It does not address the non-idempotent hint (what happens if the URL was already removed) or what the response reports.

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 short sentences, front-loaded with the core action, then the side-effect boundary, then the recovery path. Nothing is redundant.

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?

For a two-parameter, output-schema-less tool, the description covers scope, side effects, and recovery. Minor gaps: whether removing an already-absent URL errors out (idempotentHint=false) and whether the page can be re-imported afterward.

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?

With 100% schema description coverage, both parameters are already documented, including the note that the URL should come from list_existing_pages. The description adds no format, normalization, or matching-behavior detail (e.g. trailing slash or case sensitivity) beyond the schema, so baseline 3 applies.

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 scoped precisely: removes one page from Blawgy's internal existing-pages list for a site. The parenthetical examples and the contrast with restore_existing_page and list_existing_pages make it unmistakable among siblings.

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 concrete trigger cases ('a URL imported by mistake, or a page that no longer exists') and names the undo path via restore_existing_page. It does not explicitly state when not to use it versus siblings like remove_plan_entry or delete_article, but scope is clear enough to route correctly.

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