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

Annotations already declare destructive/idempotent/openWorld, and the description still adds substantial non-redundant behavior: the link dies immediately, the recipient's view shows nothing about the project, past analytics are preserved, the recipient loses access to all documents, and the default-link deletion fails with a validation error. It also discloses the human confirmation preview before the action runs.

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?

Six sentences, front-loaded with the core action and its immediate effect before moving to alternatives and constraints. Dense and mostly earning its place, though the closing untrusted-content caveat is generic boilerplate that slightly pads the definition.

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?

Complete for a destructive 6-parameter tool with no output schema: irreversible-effect semantics, undo path, revoke-without-delete alternative, the default-link exception, and the confirmation requirement are all covered. An agent has everything needed to decide and call correctly.

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%, so the baseline is 3; the description adds context for the confirm/confirmationToken/alwaysAllow flow by explaining that LinkDrop shows a preview of the link and its traffic before acting. It does not explain the projectId/projectSlug alternation beyond what the schema already says, so it stays short of a 5.

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 ('Delete one project link') and immediately clarifies scope by naming what survives (analytics kept in totals) versus what is lost (recipient access to every document). This is clearly distinguishable from sibling link tools such as lnkdrp_update_project_link and lnkdrp_delete_project.

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?

Explicitly names the two alternatives and the conditions that select them: lnkdrp_restore_share_link for a reversible restore, and lnkdrp_update_project_link with enabled:false to revoke access while keeping the link listed. It also states the when-not case (default links cannot be deleted, only disabled) with the reason.

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