anaf_create_token_link

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

The description discloses two important behavioral traits: a maximum of 5 active links per user and short link expiration. However, with no annotations provided (no readOnlyHint, no destructiveHint), the description carries the full burden for disclosing side effects. It doesn't state whether this is creates state (it does), what happens when the 5-link limit is reached, or how the returned token URL should be handled in subsequent calls. The limit and expiry disclosures are valuable but partial.

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 reasonably concise at three sentences, front-loading the core purpose and then providing key constraints (5-link limit, expiration). Every sentence contributes useful information. It could be slightly tighter, but there's no waste. The structure is effective for the information conveyed.

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 zero-parameter tool with clear description, the core function is well covered. However, given the complexity of the ANAF OAuth flow (evident from sibling tools like anaf_sync_status, anaf_tokens, anaf_status), the description doesn't explain the subsequent flow steps or how this link connects to other ANAF tools. Lifecycle context—what to do after obtaining the link, how to check completion—is missing. No output schema means the description should more thoroughly describe the return value structure.

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?

The input schema has 0 parameters, and the context signal indicates 100% schema description coverage. With no parameters to document, the baseline is 4 per the rubric. The description adequately explains what the tool returns (a unique browser-openable URL) without needing to elaborate on parameter details that don't exist.

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 clearly states the tool creates a device-based authentication token link for the ANAF OAuth flow, with a specific verb (create) and resource (token link). It provides good purpose clarity with details about the returned URL and its use in browser authentication. It doesn't explicitly distinguish from adjacent ANAF sibling tools like anaf_sync_trigger or anaf_delete_token, though the distinct 'create token link' function is evident.

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 implies this is the first step in completing ANAF OAuth flow, suggesting it should be used before authentication steps. However, it doesn't explicitly say WHEN to use this vs alternatives, nor does it mention subsequent steps like polling the token status (anaf_status/anaf_tokens). The context is implied rather than explicit, and there's no exclusionary guidance about when NOT to use this tool.

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