eda_sys_environment_is_offline_mode

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

With no annotations, the description carries the full burden of explaining behavior. It only reveals the return type (boolean) and otherwise repeats the name; it does not state that the call is read-only, stateless, requires no window context, or what true/false implies operationally.

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 short and front-loads the signature, but it repeats the same idea three times (English signature, Chinese phrase, Chinese return description). It is concise, yet some redundancy could have been replaced with more substantive context.

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 simple zero-argument boolean query, the description is minimally sufficient: an agent can call it with no args and read the boolean result. However, it lacks guidance on how this mode check fits with the online/half-offline siblings and provides no background on what full offline mode means, leaving the selection context incomplete.

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 input schema only has generic 'args' and 'windowId' fields, but the description's signature '()' clarifies that the underlying API takes no arguments. This is valuable because it prevents the agent from inventing parameters for a conceptually zero-argument predicate.

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 the tool returns whether the environment is in full offline mode, and the signature 'sys_Environment.isOfflineMode() -> boolean' plus the Chinese '全离线模式' adds a 'full' qualifier that somewhat distinguishes it from siblings like is_half_offline_mode. However, it largely restates the tool name and gives no richer explanation of what 'offline mode' means or when this predicate matters.

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?

There is no guidance about when to use this tool instead of eda_sys_environment_is_online_mode or eda_sys_environment_is_half_offline_mode. Given three closely related sibling predicates, the absence of any selection context leaves the agent to guess which one fits the scenario.

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