kopern_list_grading_runs

Read-only

List grading runs to view score history, pass rates, and version changes over time for a suite. Track performance without incurring LLM costs.

Instructions

List grading runs for a suite. Shows score history, pass rates, and versions over time. No LLM cost.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful context beyond that: it discloses that the operation incurs no LLM cost and describes what information the tool returns (score history, pass rates, versions). This enriches the behavioral understanding without contradicting the read-only hint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with purpose. The first sentence states the core action, and the second adds valuable information (what is shown and cost) without any fluff. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a simple list tool with two well-documented parameters and no output schema. The description adequately covers what the tool does and what it returns, and the readOnlyHint annotation covers safety. Nothing essential is missing for an agent to select and invoke this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with agent_id and suite_id both described. The tool description does not add any parameter-specific meaning beyond what the schema already provides, so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource: 'List grading runs for a suite,' and further clarifies the scope by mentioning score history, pass rates, and versions over time. This clearly distinguishes it from sibling tools like get_grading_results, which likely fetches specific results rather than listing runs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use the tool – to list grading runs for a suite and review history. It does not explicitly name alternatives or exclusions, but the context is unambiguous, and the 'No LLM cost' note implies safe, cheap exploration, which effectively guides usage.

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