renumber_nodes

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

Annotations provide no meaningful behavioral hints (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the description must carry the burden. It does disclose that calling without IDs renumbers all nodes from 1, which is useful, but it does not describe what happens when IDs and new_ids are partially provided, how duplicates are handled, or any side effects on dependent entities.

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 short and front-loaded, with the core behavior stated immediately and the parameter meanings summarized in a compact Args block. The bilingual repetition is mildly redundant but does not harm clarity.

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 tool with two optional parameters and no output schema, the description covers the main scenario well but leaves important edge cases unstated, such as partial renumbering semantics, relationship between ids and new_ids, and potential constraints like requiring a loaded model. It is adequate but not fully complete.

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%, so the description must compensate. It labels ids as 'List of node IDs or string format (可选，原节点号)' and new_ids as 'List of new node IDs (可选，新节点号)', which adds some meaning beyond the empty schema. However, it remains ambiguous whether the lists must have equal length, what happens if only one is supplied, and what string formats are accepted.

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 operation: 'Renumber nodes' with an explicit behavior for the no-IDs case: renumber all nodes starting from 1 continuously. The resource is specifically nodes, which distinguishes it from the sibling tool renumber_elements.

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 gives one conditional usage note ('If no IDs are provided, renumbers all nodes starting from 1 continuously') but does not explain when to choose this tool over related siblings such as update_node_id, merge_nodes, or renumber_elements. No alternatives are mentioned.

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