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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It fails to mention whether this overwrites existing sessions, validates the payload format, or what errors occur on invalid input. The mutation risk (importing state) is implied but not explicitly disclosed.

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 a single efficient sentence with no redundancy. However, given the lack of annotations and schema descriptions, it is slightly too terse—additional context about behavioral implications would improve utility without being verbose.

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 authentication tool, the description covers the core mechanism adequately but leaves gaps typical of mutation operations. Without annotations or output schema, it should disclose side effects (session replacement) and validation behavior to be complete.

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?

With 0% schema description coverage, the description compensates by explicitly identifying the vuex_payload as the value from 'browser localStorage['vuex']'. This gives the agent clear semantic context for sourcing the parameter, though it could specify expected format (JSON string, encoded object, etc.).

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 imports authentication state by pasting the browser's localStorage['vuex'] value. It uses a specific verb (붙여넣어/paste) and resource (인증 상태/authentication state), distinguishing it from sibling auth.login (fresh authentication) and auth.clear (removal).

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 provides no explicit guidance on when to use this tool versus auth.login or auth.status. While it implies this is for restoring existing sessions rather than new logins, it does not state prerequisites (e.g., 'use when you have exported Vuex data') or warn against using it with invalid payloads.

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