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

Annotations cover safety (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description adds genuinely useful behavioral context: results are returned as links to open or download, not as images, and it explains the UPI QR conditional (only when the counter QR is switched on).

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?

One dense but well-organized sentence covering all assets plus a short clarification about link-vs-image. Front-loads the primary asset (page address) first. Slightly run-on with parenthetical, but every clause 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?

Output schema exists and annotations cover safety, so the description needn't explain return values. It nonetheless clarifies the crucial 'links not images' format and the conditional UPI QR, which are the main points an agent would otherwise miss. Complete enough for a zero-param read tool.

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?

Zero parameters, so baseline is 4. The description appropriately spends no effort on parameter syntax and instead clarifies the conditional content of the return (counter UPI QR) which is the only real variable.

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 (get) and enumerates the concrete resources returned: page address, QR code, share images, and printable sheets. This is clearly distinguishable from siblings like get_embed_code or get_page_settings.

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 well by the title 'Get my page link...' and the description's enumeration, and it's clearly distinct from get_embed_code (HTML embed) and get_stream_overlays. However, it never explicitly says when to prefer this over those alternatives.

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