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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful scope information by enumerating what is returned (users, permitted projects, permitted companies), which helps the agent anticipate a composite read. It says nothing about authorization requirements, response size, or pagination, so it only modestly exceeds the annotation baseline.

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?

A single, front-loaded sentence fragment with zero filler; the keying parameter and the returned content are stated immediately. It loses a point only because the fragment lacks an explicit verb, making it slightly less self-contained than a full sentence would be.

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 one-parameter read-only tool with annotations covering safety and no output schema, the description supplies enough: the resource, the key, and the shape of the returned content. The absence of output schema means return values are not fully specified, but the enumeration of content categories largely compensates.

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 coverage is 100% and the single account_code parameter already carries a description with examples ('bcp', 'jchsoft'). The description adds only that the code selects an account workspace, which is implicit from the schema. With one parameter and full schema coverage, the baseline of 3 applies.

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 names a specific resource (the account workspace) and enumerates the content it exposes: attributes, account-level users, permitted projects, and permitted companies. It is clearly distinguishable from GetProjectTool, GetPieceTool, and GetCurrentUserTool by its account-code scoping. It is a noun phrase rather than an explicit verb, but the retrieval intent is unambiguous.

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 only usage signal is the phrase 'by account code', which implies the lookup key but gives no guidance on when to prefer this over GetProjectTool or GetCurrentUserTool, nor any prerequisite or exclusion. An agent must infer the call context entirely.

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