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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing: not whether it reads or writes, not what permissions or environment it needs, not what the 'plan' output contains. The alias list is metadata, not 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 string is short, but its brevity is under-specification rather than conciseness — there is no substance to front-load. The alias list consumes half the text without informing tool selection.

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 3-parameter planning tool with no annotations and no output schema, the description provides nothing an agent needs to invoke it correctly. Purpose, behavior, parameters, and usage context are all missing.

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 only 33%, so the description must compensate for undocumented parameters, yet it mentions no parameters at all. appType, backendMode, and requestedFeatures are left entirely to the sparse schema.

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 text 'MediaSFU Unity :: integration.plan (planner)' is essentially a restatement of the tool name plus the label 'planner'. It implies planning for Unity integration but never states what is being planned or produced, so it adds almost nothing beyond the identifier. It is close to a tautology.

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 when-to-use guidance and no reference to any alternative. The numerous siblings (unity::feature.map, unity::app.scaffold, shared::integration.plan, etc.) are never mentioned, so an agent has no basis for choosing this tool over them.

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