simulate_pk_interaction

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It mentions an 'Agent contract' that instructs on preserving certain output fields, but does not disclose traits like error behavior, unsupported drug handling, or result nature beyond the core simulation function.

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?

The description is reasonably concise with two sentences plus a contract clause, and the main purpose is front-loaded. However, the contract adds length without aiding core understanding, and the structure is somewhat informal.

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?

Given the tool's complexity (8 parameters, PK simulation, output schema exists but not explained), the description is severely incomplete. It lacks guidance on required parameters, unsupported drugs, result interpretation, and does not leverage the presence of an output schema to clarify return values.

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 only 25%, but the description adds no meaning to the parameters. It mentions 'explicit user-supplied parameters' but does not explain what fm, ki, cl_total, or inhibitor_concentration represent, leaving the agent to infer from parameter names alone.

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 specifies the verb 'Run' and the resource 'PBPK-lite CYP reversible inhibition exposure estimate', and clarifies it uses explicit user-supplied parameters for a supported drug pair. It is clear but does not explicitly differentiate from sibling simulation tools like simulate_concentration_time.

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 description does not provide when to use this tool versus alternatives. It only includes an 'Agent contract' for output handling, which is not about usage context or selection criteria.

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