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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the mutation/risk profile is known. The description adds genuinely useful semantics about what the toggle means (public URL visibility vs. owner-only draft), which contextualizes the destructive hint, but it never states the concrete consequence of unpublishing (public link stops resolving, existing visitors get an error) or that it can be reversed at any time.

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 short sentences, zero filler, with the action front-loaded and the state semantics following immediately. Nothing could be removed without losing meaning.

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 one-parameter toggle with full schema coverage and no output schema, the description covers purpose and state semantics adequately. The only notable omission is that the parameter is optional and defaults to publish, which matters for a mutation but is already captured in the schema.

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% and the single parameter already documents true=publish, false=unpublish, and the default of true. The description reinforces the meaning of each state but adds no syntax, format, or edge-case detail 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?

Clear specific verb pair (publish/unpublish) plus resource (the profile), with the observable effect spelled out (visible at urlinks.me/{username}). It does not distinguish itself from sibling update_profile, which may also be able to change publish state, so an agent cannot fully rule out overlap from the description alone.

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 only implied: reach for this when you want the profile to be publicly visible or reverted to a private draft. There is no explicit when-not guidance, no prerequisites (e.g. whether the profile must be valid or have a username set before publishing), and no reference to update_profile as the alternative for other edits.

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