A3.6/5.0

Behavior3/5

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

With annotations providing destructiveHint=true, idempotentHint=true, and readOnlyHint=false, the safety profile is already clear. The description adds that effects depend on the operation, which is mild added context, but doesn't specify what gets deleted or irreversibility details. Given annotations cover key traits, a 3 is appropriate.

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

Conciseness4/5

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

Concise at four sentences with front-loaded purpose and operation list. No redundant information, though the phrase 'Access the record delete operations listed below' could be tighter.

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

Completeness4/5

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

Given the tool is a dispatcher with rich schema and annotations, the description covers when to use it (prefer named tools), what operations exist, and that effects vary. It lacks details on the consequences of each deletion or whether operations are reversible, but annotations provide destructive hints.

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%, so parameter documentation is already thorough in the schema. The description adds only that the payload must match the selected operation, which is minimal beyond schema structure. Baseline 3 is correct.

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

Purpose4/5

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

The description identifies the tool as a compatibility dispatcher for record delete operations and lists the three supported operations (delete_context_note, delete_finding, delete_investigation). This is specific and clear, though it defers to sibling tools for the actual functionality, making it slightly less direct than a standalone delete tool.

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?

Explicitly states 'prefer the individually named tool when available', which is strong guidance. However, it doesn't elaborate on when this dispatcher should be used (e.g., backward compatibility scenarios) or provide alternatives beyond the named siblings.

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