Run several tool calls at once

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

With no annotations, the description bears full responsibility for behavioral disclosure. It mentions the nesting prohibition and the efficiency motivation, but it does not explain failure semantics, ordering of results, or error handling. This leaves significant ambiguity for a tool that executes multiple calls.

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 two sentences long, front-loaded with the main purpose, and includes a practical example and a critical constraint. Every word earns its place; no extraneous information.

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 simple parameter structure and lack of output schema, the description is not severely incomplete, but it lacks important context such as response ordering, partial failure behavior, and whether results are returned per call. These omissions could mislead an agent into assuming atomicity or a specific response format.

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 schema has no description coverage (0%), but the description provides a concrete example ('calls: [{ "tool": "find_definition", "args": { "name": "login" } }, ...]') that clarifies the expected structure beyond the raw schema. This compensates well for the lack of schema descriptions.

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: 'Execute multiple slimdex calls in one request to avoid per-call protocol overhead.' The verb 'Execute' is specific, the resource is 'multiple slimdex calls', and it distinguishes itself from other tools by focusing on batching to reduce overhead.

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 clear guidance on why to use this tool (to avoid per-call protocol overhead) and explicitly states a constraint: 'Cannot nest batch inside itself.' It could be improved by mentioning when NOT to use it (e.g., for dependent calls) but the current guidance is adequate.

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