C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and idempotentHint=false, so the safety profile is covered. The description adds only the parenthetical '(if any)', hinting that subcomplexes may be absent, but says nothing about return format, identifier resolution behavior, or what happens on an unknown id.

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?

A single compact sentence with the resource front-loaded and no filler. It is efficient, though a longer description might have earned its space by adding routing or return-format detail.

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

Completeness3/5

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

For a simple two-required-parameter lookup with no output schema, the description names both return components (participants and subcomplexes) and no nested objects exist. It is minimally adequate, but the absence of an output schema means a bit more detail on the response shape would have helped.

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% and the allowed id_type values are enumerated in the schema, so the description need not restate them. It adds no syntax, format, or cross-parameter meaning beyond the schema, so the baseline of 3 applies.

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?

States a specific verb ('Get') and resource ('list of participants and subcomplexes') scoped to 'the given identifier'. The purpose is clear and unambiguous, but there is no differentiation from the many similarly-named sibling tools (e.g. bound_molecules, molecules_ent), which all operate on identifiers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, prerequisites, or alternatives are given. The description does not indicate how this differs from siblings like molecules_ent or bound_molecules that also take an id, leaving an agent to guess which retrieval tool to pick.

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