Behavior3/5

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

The description reveals what is returned (success status, new state summary, goal reached), which gives some insight into behavior. However, it does not explicitly state that the action mutates the internal state or what the side effects are. For a tool with no annotations, more disclosure on state changes would be expected.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that front-loads the core action and mentions return values. It is not verbose, but could be improved by adding structured details like prerequisites or error behavior without significantly increasing length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool mutates state and is part of a workflow (with 9 sibling tools), the description lacks critical context: what constitutes a valid action, how to handle errors, what format the return values take, and that the state changes after execution. With no output schema, more descriptive completeness is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Both parameters (action_name, args) have descriptions in the schema with 100% coverage. The tool description adds no additional meaning beyond what the schema already provides. Baseline score is appropriate given parameter descriptions in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Execute' and the resource 'a PDDL action with given arguments', making the purpose unambiguous. However, it does not explicitly differentiate from sibling tools like pddl_init or pddl_get_current_state, which cover other aspects of the PDDL workflow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when or when not to use this tool, nor does it mention prerequisites (e.g., that the PDDL domain must be initialized first) or alternative tools for other tasks. The agent is left to infer context from the sibling list.

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