get_environment

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

No annotations are provided, so the description carries the full behavioral burden. It discloses what is detected and returned, which implies a read-only diagnostic, but it does not explicitly state whether the operation has side effects, whether the optional refresh changes cache state, or what permissions are needed.

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?

Two sentences with no filler; the scoping statement is front-loaded and the usage condition follows directly. Every sentence earns its place.

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?

An output schema exists, so the description need not explain return values, and it already lists the main environment details. It gives clear usage context. The only notable omission is the meaning of the optional refresh parameter, which is minor for this diagnostic tool.

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 schema has one parameter (refresh) with 0% description coverage, and the description does not mention refresh at all. It therefore adds no meaning beyond the schema for the only input, which is a clear gap.

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 uses a specific verb ('Show') and enumerates the exact environment details returned: Serpent executable, version, CLI flag style, data libraries, server configuration, and documentation cache status. This distinguishes it from siblings like list_data_libraries or search_docs, which serve narrower purposes.

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 explicitly states when to call it: 'Call this first on a new machine or when a run fails with ‘sss2 not found’.' This gives clear triggering conditions, but does not name alternatives or state when not to use it.

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