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

With no annotations, the description carries the full burden, and it does disclose two useful facts: the tool is retired (non-functional) and the underlying data is private to its owner. It does not say whether calls error, return empty, or which of the two parameters (both 'Ignored') have any effect.

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?

Two short sentences, with the critical 'Retired' status front-loaded ahead of the redirect. Nothing is padded, though the bracketed '[PROFILE]' tag carries little information.

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 deprecated stub the essentials are present: it says the tool is retired and where to go instead. It stops short of stating what a caller should expect if invoked (error vs. empty result) and leaves the two ignored parameters unexplained.

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%, but both parameters are literally documented as 'Ignored', so there is no real semantics to add. The description contributes nothing about query or agent_wallet, which matches the baseline for a schema that already covers its parameters.

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 labels the tool as a retired [PROFILE] tool, so an agent understands it no longer retrieves preferences, but it never actually states what the tool did or does. It relies on the name get_my_preferences plus a deprecation marker rather than giving a specific verb+resource statement.

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?

It clearly tells the agent this tool is retired and routes it to an alternative: viewing the memory signed in on VIA at the given URL. The alternative is a web destination rather than a sibling tool, so the routing is not as actionable as naming another callable tool would be.

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