TDQS

A4.2/5.0

Behavior4/5

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

Annotations already indicate destructive, non-idempotent behavior, and the description adds beyond that by disclosing that the plan is consumed after one use and that a restricted broker is involved. This gives the agent useful operational context about side effects and access constraints without contradicting the annotations.

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 a single sentence with no filler. It front-loads the verb and object, then adds the two most important operational constraints: the restricted broker and the short-lived/single-use nature of plans.

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?

For a one-parameter destructive action with an output schema and relevant annotations, the description covers plan lifecycle and access restrictions well. The main minor gap is that the term 'PID' is not expanded, but the simple input and presence of an output schema keep this from being a significant completeness issue.

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?

The schema only exposes a required string plan_id with the title 'Plan Id', and schema description coverage is 0%. The description adds lifecycle meaning by characterizing the plan as previously planned, short-lived, and single-use, but it does not explicitly say how to obtain the plan_id or what format it takes. This is adequate for a single simple parameter but not fully compensating for zero schema coverage.

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 identifies a specific action ('Execute'), a specific object ('one previously planned PID collection'), and a distinguishing delivery mechanism ('restricted collector broker'). It clearly differentiates this tool from planning and direct collection siblings by emphasizing that execution applies only to previously planned, single-use plans.

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?

It states the tool is appropriate only for collections that were previously planned, and adds that plans are short-lived and single-use, implying the agent should not attempt to reuse a plan. It does not explicitly name an alternative tool for creating plans, but the context is clear enough for correct selection.

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