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. The parenthetical '(command)' hints at execution, but it does not mention that omitting execute defaults to a dry-run (only in schema), what the command does, or the safety profile of the execute path. Significant behavioral gaps remain.

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 very short and front-loaded but conveys almost nothing, so brevity does not earn value. Structure is fine, content is hollow.

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 command-executing preflight tool with no annotations and no output schema, the description should explain what is checked and the risk of execute. None of that is present, leaving the agent guessing.

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%, so both parameters (execute, projectRoot) are fully documented in the schema. The description adds no parameter meaning, so baseline 3 is appropriate.

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 'MediaSFU Vue :: env.preflight (command)' essentially restates the name and platform with the word 'command'. It does not say what the preflight checks or verifies, only implying an environment validation step. It is distinguishable from siblings only by name, not by stated purpose.

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 invoke this tool versus runtime.diagnose or sdk.recommend, nor on prerequisites. The omission is total; nothing in the description indicates the appropriate point in the workflow.

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