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

The description adds valuable behavior not present in annotations: an undecided result records nothing and is reported instead, and the operation requires comparisons:write permission. With readOnlyHint=false this is consistent with a write operation, and the no-op behavior is a meaningful transparency gain despite not detailing return format or idempotency.

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 compact sentences front-load the core purpose and immediately add decision-rule and no-op behavior. Every sentence earns its place; the permission requirement is efficiently appended.

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 essential no-op case and permission requirement, which is useful with no output schema present. However, it does not describe the format of the reported result, the defaults behind the default decision rule, or the meaning of required set_id, leaving moderate ambiguity for an agent invoking the tool correctly.

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, but it only loosely maps to parameters: 'comparisons you name' hints at artifact_ids and 'thresholds you state' covers thresholds. The required set_id is not mentioned, and the threshold object's min_decisive, min_improved, and max_regressed fields are left unexplained.

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 a specific action ('Record an accept or reject call') and resource ('comparisons you name'), with additional detail about decisions and thresholds. It differentiates from nearby comparison-set/artifact creators by focusing on recording a verdict, though it does not explicitly name or contrast with siblings like run_comparison.

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 intended use is implied: you record a verdict over named comparisons under default or stated thresholds. However, there is no explicit guidance about when to choose this tool over run_comparison, get_comparison_verdict, or create_comparison_set, and no exclusions or alternative conditions are provided.

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