auth_status

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose what the tool reports (credential presence, session state, sync result, row counts), which is substantive. However, it omits whether this is a read-only diagnostic (likely but unstated), whether it makes external calls, or what the output format looks like, leaving the agent to infer safety and interpretability.

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?

A single, front-loaded line that opens with the purpose category ('Diagnostics:') followed by a tight list of the four report items. Every word earns its place and there is zero redundancy or filler.

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 status tool with no output schema, the description covers the report categories but not the return format or structure. An agent calling this for diagnostics will not know how to parse the response the tool returns. This is a moderate completeness gap for an otherwise simple 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?

The tool has zero parameters and the schema is empty, so the baseline of 4 applies. There is nothing for the description to add regarding parameter semantics, and no gap exists for it to compensate for.

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 a diagnostic purpose and enumerates the specific items reported (credentials present, session state, last sync result, row counts). It is readily distinguishable from all sibling tools, which are list/get/download/sync operations rather than diagnostics, so an agent can tell it apart without opening any schema.

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?

There is no explicit guidance on when to use this tool versus alternatives. The purpose makes it self-evident for checking auth/session state, and sync_now is a related sibling (the 'last sync result' item ties to it), but no when-to-use or when-not-to-use routing is given. The usage context is only implied.

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