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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether anything is mutated, not that the default mode is a dry-run, not what the check reports, not whether it requires a valid project. The only behavioral hint ('command') implies side effects without clarifying them.

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, but that brevity comes from under-specification rather than economy of expression. A single fragment that restates the identifier earns no credit for structure.

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 zero-required-parameter environment validation tool with no output schema and no annotations, the description should at minimum state what is checked and what a passing/failing preflight means. The only substantive behavior (dry-run by default) sits in the schema, and the description is silent on return semantics.

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?

Both parameters (execute and projectRoot) are fully documented in the schema with defaults and semantics, so the schema does the heavy lifting. The description adds nothing beyond it, which lands at the baseline for 100% coverage.

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 is essentially a restatement of the tool name: 'MediaSFU Kotlin :: env.preflight (command).' It adds the namespace and the fact that it is a command, but never says what a preflight check actually does or what it validates. Without opening the schema an agent cannot distinguish it from env.preflight siblings on other platforms or from runtime.diagnose.

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 guidance on when to run this versus runtime.diagnose, integration.plan, or sdk.recommend, nor any prerequisite or exclusion. The agent is left to infer usage entirely from the name.

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