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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses nothing about read/write character, side effects, permissions, or output. The only content is a name echo.

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?

It is short, but this is under-specification rather than earned conciseness. The single fragment conveys no actionable content beyond the title.

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 tool with a parameter, no annotations, and no output schema, the description should explain purpose and the backendMode choices. It instead supplies only a title echo, leaving the agent with no basis to invoke it correctly.

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 adds no meaning for 'backendMode'. The enum values (cloud, self-hosted, local) are somewhat self-explanatory, which keeps this just above the floor, but the description does nothing to explain how the mode affects behavior.

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 text is essentially a restatement of the tool name plus the platform prefix, with only the parenthetical '(security-guide)' hinting at intent. There is no verb describing what the tool actually does, so an agent cannot tell from the description alone whether it retrieves a guide, configures a proxy, or lists rooms.

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?

No when-to-use, when-not-to-use, or alternative is mentioned. With ~40 sibling tools available across platforms and shared scopes, some routing guidance (e.g. versus shared::security.proxy.rooms or android::security.proxy.rooms) would be essential, but nothing is provided.

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