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

Annotations already cover readOnly/non-destructive/closed-world, but the description goes further: it discloses the success shape (userId + organizations with workspace_id/name/role), the failure shape (error string on invalid/expired token), and the role restriction on registration. It does not mention refresh/rate-limit behavior, but adds real behavioral value beyond the 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?

Front-loaded and organized with explicit 入力/出力 structure, so the reader knows exactly what is returned. Slightly verbose in the final two sentences about workspace_id reuse, but every line carries actionable 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?

No output schema exists, so the description must carry the return contract — and it does, covering both success and failure payloads plus role constraints. Nothing an agent needs in order to call this and interpret the result is missing.

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?

The tool takes zero parameters, so per the baseline there is nothing to document. The description's 'Input: none' correctly confirms this.

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?

States a specific verb+resource: it returns the connection and authentication status to IceShore. There is no sibling tool with overlapping purpose (add_note, create_content, list_projects, etc. are all content operations), so an agent can unambiguously identify this as the auth/connection probe.

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?

It never explicitly says when to call this tool (e.g. 'call before other tools to verify the token'), but it does give downstream usage context: the returned workspace_id feeds create_content / commit_uploaded_codes and list_projects filtering, and it warns that only admin/editor roles can register. That is implied rather than explicit when-to-use guidance.

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