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

Annotations already declare this as a non-read-only, non-destructive, non-idempotent operation. The description adds genuinely new behavioural context beyond that: links to the page are rewritten (with an opt-out via update_links), and the call fails when new_path already exists. It stops short of stating permission requirements or whether the move is reversible.

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?

Two compact sentences, front-loaded with the core action and followed by the two behavioural caveats. No filler; only the awkward line wrapping keeps it from being a model of brevity.

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 mutation tool with no output schema, the description covers the two facts an agent most needs: the link-rewriting side effect and the collision failure. Annotations carry the safety profile. Missing only auth/permission expectations, which is a minor gap.

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 50%; note, agent, and workspace are documented in-schema, while path and new_path are bare. The description partially compensates by explaining the effect of update_links and clarifying that path/new_path represent the current and target locations. Baseline 3 is appropriate given the mixed coverage.

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 gives a specific verb pair and resource ('Rename or move a page') plus a side effect (link rewriting) and a failure condition. It is clear enough to distinguish from list/read siblings, though it never explicitly contrasts itself with edit_page or change_pages, which are the nearest neighbours.

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?

Usage is implied by the verb and the stated precondition ('Fails if new_path exists'), which tells the agent when the call will not succeed. However, there is no explicit guidance on when to prefer this over edit_page/change_pages or what prerequisites (permissions, existing source page) apply.

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