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

Annotations already declare readOnlyHint and openWorldHint. The description adds valuable behavioral context: cost per call and a reminder to pass fields as typed arguments. No contradictions with annotations.

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 three concise sentences: purpose, cost, read-only, and parameter guidance. No fluff or redundant 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?

While output schema exists and purpose is clear, the description lacks details on how threshold and max_records affect results, and what 'structurally similar' means. Adequate but not fully complete for a chemistry tool.

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 100%, but descriptions are minimal ('cid parameter', etc.). The tool description does not clarify the meaning of threshold or max_records beyond the schema. Baseline 3 applies due to high coverage, but no added value.

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 clearly states the tool finds structurally similar compounds in PubChem, using a specific verb and resource. It distinguishes from sibling chemistry tools (e.g., bioactivity, compound) by focusing on similarity.

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 mentions the tool is read-only and costs $0.002, implying safe usage, but does not provide explicit when-to-use or alternatives among the many research tools. The usage context is implied rather than explicit.

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