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. It does disclose the tool's nature as a first-call intent-mapping oracle rather than a mutating operation, which is genuinely useful context. It does not state that it is read-only, whether it has no side effects, or anything about rate limits or response shape beyond the conceptual mapping.

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?

Two sentences, tightly written, with the critical action-first directive ("Call this first") front-loaded. No filler or restated title content.

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 zero-parameter, annotation-free, output-schema-free discovery tool, the description adequately conveys what the agent gets back (intent/alias to tool mapping) and when to call it. It could be slightly more complete by clarifying how it relates to the other catalog-style siblings, but nothing essential is 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?

The schema has zero parameters, so per the rubric the baseline is 4. There is nothing for the description to explain, and it correctly avoids inventing parameter guidance.

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 states a specific function: a discovery/router tool that maps user intents and model aliases to the correct Sequencer MCP tool, and enumerates the covered domains (image, video, audio, music, storyboard, edit, workspace, media). It is clearly not a generator or editor. However, it doesn't distinguish itself from other discovery siblings like get_available_tools, get_feature_list, or get_usage_guide, so sibling differentiation is only implied.

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?

"Call this first when deciding whether Sequencer can help with a user request" gives an explicit trigger condition and even an ordering rule. It stops short of naming alternatives or when-not-to-use conditions (e.g., when a concrete tool is already known), leaving some routing ambiguity against the other list/get-capability siblings.

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