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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, but the description goes well beyond them: it discloses the permanence of the effect including already-printed QR codes, the default-page precondition, the guidance to confirm with the user and name what changes, and that a read after an error or timeout reveals whether the change landed rather than retrying blind. It also states the permission model ('Any member can use it').

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 critical fact — deletion and its 404 consequence — is front-loaded, and each subsequent sentence carries distinct information (precondition, confirmation, error recovery, permissions) with no filler. It is dense across five clauses rather than wasteful, though the destructive-warning sentence partly overlaps the destructiveHint annotation and could be trimmed.

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 destructive mutation with an output schema present, the description covers everything an agent needs: irreversibility, the default-page blocker and its workaround, confirmation expectations, retry-after-error behavior, and who may call it. Return values need not be explained because the output schema exists.

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% and both parameters (page_id sourced from list_link_pages, workspace_id from list_my_workspaces with its multi-workspace requirement) are documented in the schema itself. The description adds no further meaning about either parameter, so the 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?

The opening clause names a specific verb and resource ('Delete a page') and immediately states the observable consequence ('its address answers 404 from then on, printed QR codes included'), which makes it unmistakable against siblings like update_link_page, duplicate_link_page, or delete_folder.

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?

It states an explicit exclusion (the default page cannot be deleted) and names the alternative that unblocks it ('make another page the default first (update_link_page with make_default)'), plus adds a confirmation guideline naming what will change. An agent has both the when-not condition and the routing decision without inference.

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