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: no return shape, no side effects, no auth requirements, no idempotency. "mapper" hints at a transformation but says nothing about what is transformed into what.

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 the brevity comes from under-specification rather than efficiency. There is nothing to front-load because no substantive content exists.

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 with an input parameter, no annotations, and no output schema, the description should explain purpose, inputs, and behavior. It supplies none of these, leaving the agent unable to invoke it correctly.

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?

The single parameter "requestedFeatures" has 0% schema description coverage and the description adds zero meaning beyond the field name. There is no mention of accepted values, format, or the 32-item/80-char constraints.

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?

"feature.map (mapper)" merely restates the tool name; the parenthetical adds no information. Only the MediaSFU Angular namespace is conveyed, so an agent cannot tell what the tool actually maps or produces, nor how it differs from siblings like shared::feature.map or integration.plan.

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?

The description contains no when-to-use, when-not-to-use, or alternative-tool guidance. With 100+ sibling tools sharing the feature.map name across platforms, the absence of any routing signal is a serious gap.

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