vod_auth_status

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

With no annotations, the description carries the burden and does well: it declares read-only behavior, that no key is required to run, and importantly that key material is reported as a fingerprint rather than plaintext (a security-relevant disclosure). It does not describe response size or latency, but for a self-diagnostic tool the essential behavior is covered.

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 dense sentence with parenthetical clarifications; every clause lists a distinct capability. It is somewhat compressed with multiple comma-separated clauses, but nothing is redundant.

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?

There is no output schema and no annotations, so the description must stand alone, and it largely does by enumerating the reported fields and the missing-key guidance output. However, it does not describe the output shape or format of those reports, leaving some ambiguity about what an agent will receive.

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 baseline of 4 applies; the description correctly adds no parameter noise and instead spends its words on what the tool inspects.

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 names a specific operation (self-check of authentication) and enumerates the exact things reported: dual-backend key configuration state, connectivity, environment pointing, and active packs. This is clearly differentiated from the sibling tools (submit/list voices, devkit info), though it never names them explicitly.

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?

Implies its use case by stating it is read-only and runs even without a key configured, which signals a diagnostic/troubleshooting role, and it notes that missing keys produce structured application guidance. There is no explicit when-to-use-vs-alternative routing and no stated exclusions.

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