deduplicate_trees

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

No annotations are present. The description explains the behavior 'keeps the first occurrence' and 'removes duplicates' but lacks details on side effects, reversibility, or state changes.

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?

Two highly compact sentences with no redundant information. The first sentence front-loads the core action, and the second adds clarifying detail.

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 parameterless dedup tool without output schema, the description adequately explains the operation. It could mention return value or side effects but is sufficient given simplicity.

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 tool has zero parameters, so the description's mention of 'normalized goal' provides the only relevant semantic. The schema coverage is 100% (empty), earning a baseline of 4.

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 verb 'Deduplicate' and resource 'trees' with the specific criterion 'by normalized goal'. It distinguishes from sibling tools like deduplicate_strategies which operate on different resources.

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 implies usage for deduplicating trees but does not explicitly state when to use versus alternatives. No exclusions or prerequisites are provided.

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