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

With no annotations at all, the description carries the full burden of behavioral disclosure. It states the scope ('all' elements/components) but says nothing about non-mutating behavior, return format, ordering, pagination, or project access requirements, leaving the agent to infer those traits from the verb alone.

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 entire description is one lean sentence with the verb and object front-loaded. The parenthetical is compact and informative; there is no filler or redundant restatement of the tool name.

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 simple one-parameter list tool, the description covers the core purpose, but with no output schema or annotations it does not state what the response contains or how to interpret the result. An agent can select the tool confidently but would still have to discover return semantics elsewhere.

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 input schema has 100% coverage with a single 'Project ID' description, so the schema carries the parameter documentation. The description adds only that the elements belong to 'a project,' matching projectId, but provides no extra format or usage detail. Baseline 3 is appropriate.

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 names a specific verb ('List'), a concrete resource ('elements/components'), and scopes it to a project. The parenthetical enumerates the categories of elements, making the resource clear, though it does not explicitly contrast this with sibling list tools.

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?

No guidance is given on when to prefer this tool over sibling tools like list_entries, list_knowledge, or list_files, and no exclusions or preconditions are stated. The only usage signal is the phrase 'of a project,' which is not enough to route an agent among the many list_* alternatives.

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