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. It reveals nothing about whether the tool is read-only or mutating, what permissions it needs, or what side effects 'planning' has. A single noun phrase cannot cover a behavioral profile.

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 this is under-specification rather than conciseness. A single fragment with no structure or front-loaded intent does not earn brevity credit because nothing meaningful is being conveyed.

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 complex cross-cutting planning tool with three inputs, no annotations, no output schema, and only 33% parameter coverage, the description supplies none of the missing context. An agent cannot determine what the plan covers, what features are valid, or how backendMode affects the result.

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 33% (appType and the requestedFeatures item have one-line descriptions; backendMode is an enum). The description adds nothing about any parameter, so with low coverage it fails to compensate. Slightly better than the 0%-coverage floor only because the schema partially self-documents.

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 :: integration.plan (planner)' essentially restates the tool name with the word 'planner' appended. It conveys the platform (Vue/MediaSFU) and that some planning occurs, but no verb+resource statement of what the tool actually produces or does. It is a tautology of the name rather than an explanation.

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, no prerequisites, and no differentiation from the many siblings (app.scaffold, feature.map, env.preflight, sdk.recommend, room.bootstrap). An agent has no basis to choose integration.plan over any other Vue tool in the list.

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