pddl_is_goal_reached

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action but does not explicitly confirm it is read-only, mention side effects, or specify preconditions like initialization. This is insufficient for an agent to understand the tool's safety and dependencies.

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 very concise at six words, with no wasted text. It is front-loaded with the key action. However, it could benefit from a slight expansion (e.g., on return value) without sacrificing conciseness, so it is not a perfect 5.

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?

The description is incomplete: it does not specify the return type (implied boolean but not stated), nor does it mention behavior when no goal is defined or when planning is not initialized. Given zero parameters and no output schema, the description should clarify these aspects to be fully useful.

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 zero parameters and schema description coverage is 100%, so no parameter information is needed. The description adds no extra value for parameters, but the baseline of 3 is appropriate given the high coverage.

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 tool's function: checking if the goal state has been reached. It uses a specific verb ('Check') and a specific resource ('goal state'), and it distinguishes itself from sibling tools like pddl_get_current_state or pddl_execute_action, which have different purposes.

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 no guidance on when to use this tool versus alternatives, such as checking the current state manually or after executing actions. There are many sibling tools, but no exclusions or context about prerequisites (e.g., being initialized) are mentioned.

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