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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The phrase 'This call asks no human' adds genuinely useful context that the call is non-interactive and needs no approval, but nothing is said about what the response contains or how omissions of optional params are handled.

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 short sentences with no wasted text, and the prerequisite list is front-loaded. 'This call asks no human' is slightly cryptic but is doing real work in one clause.

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 two-param read-only check with no output schema, the description should hint at the shape of the answer (a list of missing items?) and what happens with no arguments. It names the categories of prerequisites but leaves the return structure and default scoping 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?

Schema coverage is 100% and both parameters are documented there, so baseline 3 applies. The description adds nothing about project/environment semantics, and notably does not clarify behavior when both are omitted (required=0), which would have been valuable.

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 conveys the intent indirectly: it reports outstanding prerequisites (servers, GitHub connection, cluster domain) before a deploy. But there is no clear verb+resource construction such as 'list' or 'check,' and 'environment_setup' could be misread as a mutation tool. An agent must infer the operation from the enumerated items.

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?

No guidance on when to call this versus siblings like environment_show, deploy, domain_check, github_ls, or server_show, which all touch the same prerequisite surface. The deploy context is implied but no exclusions or sequencing advice are given.

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