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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It mentions the returned fields but does not say whether the operation is read-only, what the response format is, whether errors can occur, or how the id is used. This is a minimal description that reveals output content but almost no behavior.

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 very short, front-loaded with the core meaning, and contains no filler. The alias note is relevant for tool selection)Skip. Every sentence serves a purpose.

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?

For a single-parameter getter with no output schema and no annotations, the description is serviceable but not complete. It gives the main return fields and a routing hint, but it omits what PCC means, what id refers to, and any behavioral or error expectations. An agent could probably call it correctly, but only with reasonable inference rather than explicit guidance.

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 0%, and the description does not mention the id parameter at all. The schema only says id is a required string, so the agent must infer that id identifies the PCC entry. 'One entry' hints at a lookup-by-id operation, but the description adds no real semantic value beyond the schema.

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 states that the tool returns 'one entry with notes, price, and links,' which conveys the resource and result shape. It does not use an explicit verb like 'get' or 'fetch,' but the tool name pcc_get plus the contrast with aware_get make the purpose reasonably clear. It also distinguishes itself from the search siblings by emphasizing a single entry.

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 tells the agent to 'Prefer this' and notes that aware_get is a retired alias, which is useful routing guidance. However, it does not explain when to choose pcc_get over pcc_search or other getters. The guidance is implied by the name and sibling patterns but not stated explicitly.

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