Read runtime configuration status

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 one meaningful behavioral trait: the result reports local configuration presence and must not be read as an upstream connectivity check. However, it says nothing about read-only semantics, permissions, latency/rate behavior, or what the report 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?

A single front-loaded sentence with an appended scope caveat; nothing is padded or redundant. Slightly awkward phrasing ("Report whether ... has its required configuration") keeps it from a 5.

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?

The tool is trivial in shape (zero params, no nested objects) but there is no output schema, so the description should say something about what the report looks like — a boolean, a status string, a list of missing keys. It only conveys that a configuration determination is made, leaving the return value unstated.

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, which is the documented baseline of 4. There are no arguments whose semantics could be clarified or omitted.

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 ("Report") and a precise resource ("whether this isolated WhatsApp adapter has its required configuration"), which is a genuine narrowing from the vague tool name personal_system_configuration. No sibling tools exist to differentiate from, so it cannot reach the 5 criterion.

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 statement of when to call this tool versus alternatives, nor any precondition or agent-facing trigger. The trailing clause "this does not claim an upstream connection" is scope disambiguation, not usage guidance.

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