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

With no annotations, the description carries the burden, and it does disclose substantive behavioral commitments: the protocol is versioned, eligibility is immutable, and the budget is finite and reserved. These are real side-effect traits beyond the schema. It still omits auth requirements and exact response behavior, but the core behavioral profile is clear.

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?

A single sentence with no filler; the action and distinguishing constraints are front-loaded. Every phrase adds meaningful 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?

This is a nested-parameter creation tool with no annotations and no output schema, so more explanatory context is needed. The description does not cover how to form the run object, what idempotencyKey should contain, what the response is, or how this relates to research_definitions and budget workflows.

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 explain parameters, but it only loosely maps to 'eligibility' and 'budget'. It does not explain the required idempotencyKey, nor the nested run object's definitionId, title, or visibility, leaving an agent without enough semantics to construct valid arguments.

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 opens with the imperative 'Create' and targets a well-defined resource, 'a versioned research protocol,' which aligns with the tool name. The qualifiers (immutable eligibility, randomization seed, finite reserved budget) clearly distinguish it from generic create_* siblings and from research read/update tools.

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 'Create' verb implies this is the tool for instantiating a new research run rather than mutating one, but the description never explicitly states when to use it over siblings like set_research_state, research_definitions, or issue_budget. Usage is inferable, not stated.

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