sas_viya_sign_out

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

Annotations declare readOnlyHint=false and destructiveHint=false, so the safety profile is partly covered, but the description adds nothing beyond that: it does not say whether credentials or tokens are actually discarded, whether other sessions are affected, or what side effects follow. For a state-changing session tool this is a notable gap.

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 short sentence with no filler, front-loading the action. It is efficient, though borderline under-specified rather than truly concise.

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, no-output-schema tool the description is minimally viable, but it omits anything about post-conditions or interactions with the sibling SAS Viya session tools. Adequate but with clear gaps.

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 takes zero parameters, so the schema imposes no semantic burden and the baseline is 4. There is nothing for the description to clarify on the parameter side.

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 conveys that the tool ends a SAS Viya session, and the name plus the phrase 'sign-in' make the resource recognizable. However, 'Forget' is a metaphorical verb that leaves ambiguous whether it clears cached credentials, revokes a token, or merely drops session state. It does not explicitly distinguish itself from sas_viya_sign_in or sas_viya_state.

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 guidance on when to invoke this versus sas_viya_sign_in, sas_viya_save, or sas_viya_state, nor any statement of prerequisites (e.g. must already be signed in). The agent must infer the trigger condition from the name alone.

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