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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds useful behavioral context beyond annotations: this tool renders a human-facing UI, returns a snapshot, and is not a live data check.

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 description is compact and front-loaded: a scannable contents list followed by one sentence explaining the human-facing purpose. The sibling guidance is included without wasting words or repeating structured annotation data.

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, read-only, idempotent UI-rendering tool, the description provides what an agent needs: what is rendered, for whom, snapshot semantics, and the closest alternative for data retrieval. The absence of an output schema is acceptable given the tool's explicit human-viewing purpose.

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?

There are zero parameters and the schema is fully specified with additionalProperties false, so there is nothing to document. The no-parameter baseline of 4 applies; the description wisely adds no parameter-related content.

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 starts with 'Repository tree' and enumerates the exact components: snapshot Metric cards, per-directory bar chart, and clean file table. It states the specific verb 'Renders' and distinguishes the tool from rrt_tree by clarifying it produces a UI widget rather than data values.

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 explicitly tells the agent when to use this tool: when a human needs to look at a UI widget. It names the alternative, rrt_tree, for when values are needed for reasoning, and warns that the data is still a snapshot, not a live check.

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