visualize_edge_tool

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

No annotations are provided, so the description must disclose behavioral traits. It states the tool highlights edges and saves a PNG, which implies file creation, but does not mention side effects like overwriting behavior, required file permissions, or whether the network file is modified. Basic transparency, but missing details.

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 front-loaded with the purpose, followed by bullet-point usage guidelines and an args list. It is relatively concise, though the args section is somewhat redundant with the schema (justified by lack of schema descriptions). Minor room for trimming.

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?

Given 3 parameters, no output schema, and no annotations, the description covers the basics: what it does, when to use, and parameter meanings. However, it omits output file naming, return value (if any), and prerequisites (e.g., net_file must exist). Incomplete for full context.

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 0% description coverage, but the description's Args section adds one-line explanations for all three parameters (net_file, road_name, output_dir), which adds meaning beyond the schema. However, the descriptions are minimal (e.g., road_name format not specified), so not a perfect score.

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 clearly states 'Visualize a SUMO network file with selected edges highlighted and save as PNG image,' providing a specific verb and resource. However, it does not explicitly differentiate between sibling tools like visualize_edgedata_tool or visualize_net_tool, leaving some ambiguity.

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 provides explicit guidance with examples of when to use ('show edge details', 'visualize this road') and when not to use ('which road is congested?' → answer with text). This strongly aids the agent in correct invocation.

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