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

Annotations indicate destructive and non-idempotent behavior, which the description does not contradict. However, the description does not add extra context about side effects, such as that grades will be permanently changed or that concurrent processing may have race conditions. Given the annotations already cover the destructive nature, the description provides minimal additional transparency.

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 extremely concise, consisting of two short sentences. It avoids redundancy and includes only essential information about the tool's function and approach (concurrency and batch processing). This is an optimal length for a tool description.

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 covers the core purpose and mentions concurrency, which is a key operational detail. It does not explain error handling or partial failures, but that is not strictly necessary. Given the rich parameter descriptions in the schema, the description is sufficiently complete for an agent to understand the tool's role.

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?

All parameters have descriptions in the schema, so the description does not need to explain them. The description adds no extra semantic details beyond what the schema already provides (e.g., the structure of 'grades' dict). Since schema coverage is 100%, the baseline is 3, and the description does not enhance parameter understanding.

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 purpose: grading multiple submissions efficiently and in batches. It distinguishes itself from single-submission grading tools by mentioning 'bulk' and 'concurrent processing,' though it could further clarify that it handles grading for an entire assignment at once.

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 does not explicitly state when to use this tool versus alternatives like 'grade_with_rubric' or 'assign_peer_review.' It implies bulk usage through 'multiple submissions' and 'batches,' but lacks explicit guidance on scenarios (e.g., when grading many students at once) or when to prefer it over other grading tools.

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