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

Goes well beyond the annotations (destructive=true, idempotent=true): it discloses the permission model (only the document owner or link creator can decide), rate and reversal limits matching the app, the side effects of each branch (approve emails a download link or offers the latest version; deny notifies the requester), and repeated untrusted-content warnings about the requester's note and result text. This is exactly the added context annotations cannot carry.

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 core action and addressing are front-loaded, and each subsequent sentence carries distinct value (permissions, limits, branch effects, untrusted content). It is dense and long, but there is little that could be cut without losing behavioral disclosure.

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?

No output schema exists, so the description must carry the full burden; it does. It covers who may decide, what each decision causes, the confirmation prerequisite, refusal behavior, rate limits, reversibility, and untrusted-content handling — everything an agent needs to invoke it 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 genuine meaning by framing notificationId and request.requestId as alternative addressing handles both sourced from lnkdrp_get_notifications, clarifying their relationship rather than restating types.

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 pair (approves or denies) on a specific resource (one download request waiting for the person), and distinguishes itself from siblings like lnkdrp_confirm_action and lnkdrp_check_approval by its subject matter. The addressing keys (notificationId / request.requestId) are named up front.

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 clear context: IDs come from lnkdrp_get_notifications, the person must confirm in lnkdrp's own prompt, and there is no confirm flag. It even states the negative condition — a client that cannot show the prompt cannot decide and the call refuses. It does not name an explicit alternative tool beyond the notification source, so it stops short of a full 5.

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