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. A scaffolding tool writes files into the consumer project (the schema's 'apply' and 'overwrite' flags imply potentially destructive writes), yet the description never mentions side effects, dry-run defaulting, file creation, or required permissions.

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 sentence is short but not concise in any meaningful sense: it is a bare identifier echo with zero informational payload. Brevity here reflects under-specification rather than economy.

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 tool that generates and writes project files with 4 parameters, no annotations, and no output schema, the description is far too thin. The schema documents the knobs, but the description gives no account of what the scaffold produces or how it interacts with the rest of the MediaSFU workflow.

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 100%, with clear inline docs for apply, outputDir, overwrite, and projectRoot, so the baseline is 3. The description adds no meaning beyond the schema, but it is not required to given the 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 Angular :: app.scaffold (scaffold).' It conveys no verb+resource explanation beyond what the identifier already implies, and nothing distinguishes it from the dozens of sibling 'app.scaffold' variants other than the platform prefix baked into the name itself.

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 use this tool versus alternatives such as integration.plan, room.bootstrap, or env.preflight, nor any statement of prerequisites or ordering. The agent must infer the scaffolding role 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.
