Nano Banana 2 Temporary

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

No annotations provided, so the description must fully disclose behavioral traits. It lacks information on side effects, idempotency, rate limits, or whether the tool is read-only or destructive. It mentions 'per-call' settings but does not explain how the tool behaves with those parameters.

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 composed of two sentences, making it concise. However, the first sentence is awkwardly phrased ('Gemini generateContent-compatible exploration tool') and could be clearer. It front-loads key information but sacrifices some clarity.

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 the tool's complexity (10 parameters, 6 required, output schema present), the description is insufficient. It does not explain the output, the role of save_path, or the significance of image parameters. Sibling tools with similar names add confusion. The description lacks completeness for effective agent use.

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%. The description mentions only 4 of 10 parameters (api_key, base_url, model, timeout) without adding detail beyond their names. Critical parameters like prompt, save_path, version, and image settings are not explained, leaving the agent with insufficient meaning.

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 it's a temporary exploration tool compatible with Gemini generateContent, and lists key parameters. However, the verb 'exploration' is vague and does not clearly state a specific action like 'generate' or 'create content'. It distinguishes from siblings by being 'temporary' but does not fully clarify its core purpose.

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 testing with unknown providers via per-call settings, but does not explicitly state when to use this tool versus the official counterparts (nano_banana_2_official, gpt_image_2_official). No guidance on when not to use it or specific contexts.

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