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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, covering the safety profile. The description adds a sense of output completeness ('Everything about one site') and names returned fields, but since an output schema exists, this mostly repeats structured data and adds no auth, rate-limit, or error behavior.

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?

The description is a single front-loaded sentence with a clean colon list. Every element serves the purpose of clarifying scope and returned detail, with no wasted words.

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 read-by-id tool with rich annotations and an output schema, the description is complete enough. It states the retrieval scope, the source of the id, and what 'full' means, leaving nothing critical for an agent to infer.

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?

Schema description coverage is 100%, and the public_id parameter is fully documented with format and origin ('the last part of a site's URL'). The description echoes 'from an earlier answer' but adds no syntax or meaning beyond the schema, so the baseline of 3 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 specific resource ('one site') and clearly scopes it to full detail retrieval from an earlier answer, distinguishing it from search/list siblings like find_chargers. An agent can tell this returns complete site data rather than a collection or summary.

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?

The phrase 'from an earlier answer' gives a clear usage context: this tool requires a public_id already obtained from another call. It does not explicitly name find_chargers as the alternative or state when not to use it, but the context is sufficient.

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