A4.3/5.0

Behavior4/5

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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds genuine behavioral detail beyond them: recruitment stops, the target cycle closes, and the reward hold is settled/released — telling the agent what actually changes. It does not, however, state irreversibility or what happens to already-collected interviews/participants.

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?

Two sentences, zero filler. The destructive scope is front-loaded and the gating condition follows, so the highest-risk information arrives first.

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?

An output schema exists, so return values need no explanation, and annotations carry the safety/idempotency profile. Given the tool's complexity, the description covers effects and the human-approval gate completely enough for correct invocation.

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 coverage is 50%: organization_id is fully documented in the schema, while study_id carries only a format/pattern. The description says nothing about either parameter, but study_id is self-evident from the tool's purpose and the admin-only scoping of organization_id is already in the schema. Adequate, not additive.

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?

Names a precise verb and resource (stop panel recruitment / close target cycle) and enumerates the concrete side effects, including settling or releasing the reward hold. This is materially distinguishable from siblings like pause_study (reversible halt) or delete_study (removal), so an agent can route correctly without opening the schema.

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?

Provides an explicit precondition: call only after the human explicitly chooses to end this study's fieldwork. That is a real gating rule. It stops short of naming alternatives (pause_study, delete_study) or stating when NOT to call it, so it is clear context but not full when/when-not guidance.

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