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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the non-mutating safety profile is covered. The description adds value by specifying the six things it inspects, but says nothing about permissions/auth needs, whether detection triggers network calls to the chain, or side effects. Adequate with annotations, but not rich.

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?

Two tightly written sentences, front-loaded with the primary action and a compact enumeration of the detected domains, followed by a single usage cue. No filler, no repetition of the name. Efficient overall.

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?

With no output schema and no parameters, the description carries the burden of describing what a caller gets back. "See what's configured and what's missing" gestures at the result but does not characterize the return shape (e.g., per-domain status object, boolean flags). Sufficient to call it correctly, but thin on result expectations.

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 beyond what the empty schema conveys. Baseline of 4 applies; there is no param-level meaning the description could usefully add.

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 (auto-detect) and resource (current setup state), then enumerates the exact domains checked: env vars, database, adapters, chain connectivity, storage, identity. An agent immediately understands the scope. It does not explicitly distinguish itself from adjacent siblings like setup_status or setup_validate, so it stops short of a 5.

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?

"Use this to see what's configured and what's missing before onboarding" gives clear timing/context for when to reach for it. However, it names no alternatives (e.g., setup_status for a read-only summary vs setup_validate for verifying correctness) and provides no when-not guidance, so routing between the setup_* siblings is left to inference.

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