sfc_credential_status

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

No annotations, so the description carries the full burden. It does disclose a genuine behavioral trait — the response will not expose secret material — which is useful for an agent deciding whether to call it. It does not state that it is read-only (implied), nor what the response actually contains.

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 short sentence, front-loaded with the operation and followed by the one caveat that matters. Nothing wasted.

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 trivial zero-parameter status check, this is close to adequate, and the no-output-schema rule means return values needn't be detailed. Still, the agent cannot tell what a positive/negative result looks like or whether this confirms reachability versus mere configuration.

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 there is nothing for the description to disambiguate; baseline 4 applies.

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 (check) and resource (whether SFC credentials are configured), which is clear on its own. However, it does not differentiate itself from the near-identical sibling sfc_verify_credentials, leaving the agent to guess at the boundary between 'status' and 'verify'.

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?

No when-to-use guidance is given beyond the implied 'check before operating'. With siblings sfc_verify_credentials and sfc_setup present, the description should say which to call when, and it says nothing.

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