photo_share_link

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

Annotations declare this is a destructive mutation (readOnlyHint=false, destructiveHint=true), and the description adds valuable behavioral detail beyond them: stopping preserves the link, sharing again resets settings, and password/expiry are refused without public access. It does not cover permissions or rate limits, but the added context is substantial.

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 description is three tight sentences with no wasted words. The core purpose is front-loaded, followed by key behavioral constraints. Every sentence earns its place.

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 six-parameter mutation tool with no output schema, the description covers the essential calling context: action semantics, cross-parameter constraints, and personal-space-only scope. It does not describe return values, but the schema action descriptions partly compensate and the tool is still callable correctly from this definition.

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%, so the schema already documents all parameters in detail. The description reinforces cross-parameter constraints (password/expiry need public view or download) and action semantics, but most of that information is already present in the schema. Baseline 3 is appropriate.

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 states a specific verb and resource (share a Synology Photos album by link) and enumerates the actions (change public access, password, expiry, members, stop sharing). It also scopes the tool to personal space albums only. However, it does not explicitly differentiate itself from sibling tools such as list_shares or photo_album.

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?

The description gives clear when-to-use context and constraints: password or expiry requires public view or download, stopping keeps the link, and re-sharing resets settings. It also limits the tool to personal space albums. It stops short of naming alternative tools and when to prefer them.

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