Create a Firefox Reverse environment

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

No annotations are provided, so the description carries the full burden. It mentions that the kernel version and system follow 'Firefox Reverse' and that the default locale is mainland China Simplified Chinese, which offers some behavioral context. However, it does not disclose side effects, resource allocation, required permissions, or what return value to expect, which is a significant gap for a creation tool.

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, front-loaded sentence with no unnecessary fluff. It efficiently conveys the core action and a couple of key defaults, though it could be slightly more informative without sacrificing conciseness.

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?

With 6 optional parameters, no output schema, and no annotations, the description is too sparse to be complete. It does not explain what 'Firefox Reverse' refers to, what happens after creation (e.g., whether it opens automatically or returns an ID), or how parameters interact. This is a substantial gap for a tool with this complexity.

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 100%, so the baseline is 3. The description adds minimal parameter context by indicating a default locale, which the schema does not state, but it does not elaborate on any other parameters. No additional syntax or meaning is provided beyond what the schema already gives.

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 explicitly states '一键新建 Firefox 环境' (one-click create Firefox environment), clearly identifying the action (create) and the resource (Firefox environment). It also distinguishes itself from sibling tools like frx_env_rename and frx_env_delete by focusing on creation.

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 implies it is for creating a new Firefox environment with defaults, but it does not explicitly state when to use this tool versus alternatives like frx_env_import_json or frx_env_import_capture. No exclusions, prerequisites, or comparison to other creation methods are provided.

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