Import a full Firefox Reverse environment JSON

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

No annotations are present, so the description carries the full burden. It discloses key behavioral traits: only Firefox fingerprints are accepted for new environments, two supported JSON formats are listed, and overwrite:true is required when the ID already exists. It does not mention error behavior or side effects beyond overwrite, but it provides meaningful constraints beyond the schema.

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 two short sentences, front-loaded with the core action and resource. It efficiently packs format variants and the overwrite rule without redundancy or irrelevant details.

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?

Given 5 optional parameters and no output schema, the description covers the primary input formats and the overwrite constraint. It lacks explicit success/error behavior and does not distinguish between text and config parameters, but the schema descriptions and title cover most of that ground, making this reasonably 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?

Schema coverage is 100% for the 5 parameters, so baseline is 3. The description adds value beyond the schema by specifying accepted JSON structures ({name,id,fingerprint,proxy,generateOptions} or {env,fingerprint,proxy}) and explaining when the overwrite parameter is necessary, enhancing the minimal field descriptions.

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 a specific action: '导入完整环境 JSON' (import full environment JSON), identifying the resource and scope. It distinguishes from the sibling frx_env_import_capture by focusing on full JSON import rather than capture-based import, and from frx_env_create by the import semantics.

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 usage context: importing a full environment, with explicit constraints that new environments only accept Firefox fingerprints and that existing IDs require overwrite:true. It does not explicitly name alternative tools (e.g., frx_env_create, frx_env_import_capture) or state when not to use this tool, but the context signals are clear enough for selection.

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