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

With no annotations, the description carries the full disclosure burden. It does add one real trait — that it runs the same code as the tool page, implying parity with the web UI — but says nothing about whether the call is read-only, what data sources are touched, latency, rate limits, or what the response contains (there is no output schema to cover that).

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?

It is short with no wasted words, but the brevity comes at the cost of clarity: three clipped fragments ("AI readiness.", "Runs the same code the tool page runs.", "Scope: check.") read like notes rather than a front-loaded explanation of what the tool does.

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 simple one-parameter read check this could be adequate, but the critical gap is ambiguity against check_ai_readiness, which the description does nothing to resolve. With no annotations and no output schema, the description should at minimum say what is checked and what comes back.

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?

There is a single parameter at 100% schema description coverage, and the schema already states "Domain name, no scheme." The description adds nothing beyond that, so the baseline 3 for fully documented schemas 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?

The description names a resource area ("AI readiness") but never states a verb or what the check actually evaluates, and it gives no clue how this differs from the near-identically named sibling check_ai_readiness. "Scope: check" is a fragment rather than a purpose statement, so the agent must infer intent from the name alone.

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 when-to-use guidance and no mention of when-not-to-use, despite a sibling (check_ai_readiness) that appears to cover the same subject. The only scoping hint is the fragment "Scope: check," which does not tell an agent how to choose between the two AI-related tools.

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