graph_coloring

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the algorithm but doesn't disclose whether the graph is mutated, what the output format is, or any side effects. For a graph algorithm tool, this is a significant transparency gap.

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 appropriately brief at one sentence, but it is under-specified. It lacks structure or any breakdown of parameters. It earns its place only by stating the core purpose, but could be improved with minimal additions like strategy options or output description.

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 the tool's complexity (graph algorithm), lack of annotations, output schema, and 0% schema coverage, the description is severely incomplete. It doesn't explain return values, side effects, or parameter semantics, leaving the agent without enough information to invoke the tool 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?

Schema description coverage is 0% and the description adds no meaning to the parameters. The 'strategy' parameter is not explained (e.g., what values like 'largest_first' mean), and the 'graph' format (string) is ambiguous. The description does nothing to compensate for the missing schema documentation.

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 the action ('Color graph vertices') and specifies the method ('using greedy algorithm'), making it distinct from sibling graph tools like shortest_path or pagerank. It uses a specific verb and resource.

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 provided on when to use this tool versus alternatives. It doesn't mention any prerequisites, use cases, or situations where graph coloring is appropriate or not. Sibling tools like community_detection could be alternatives, but no distinction is made.

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