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

With no annotations provided, the description carries full burden but provides minimal behavioral information. It mentions the PRO feature requirement but doesn't disclose what happens during generation (e.g., file creation, overwriting behavior), error conditions, rate limits, or authentication needs. The description doesn't contradict annotations since none exist, but it's insufficient for a mutation 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 extremely concise with just one sentence that efficiently communicates the core functionality and pricing context. Every word earns its place with zero waste or redundancy.

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 mutation tool with 6 parameters, 33% schema coverage, no annotations, and no output schema, the description is inadequate. It doesn't explain what the tool returns, how errors are handled, what the screenshots look like, or provide sufficient parameter guidance. The PRO feature mention is helpful but doesn't compensate for major gaps.

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 only 33% (2 of 6 parameters have descriptions). The description adds no parameter information beyond what's in the schema - it doesn't explain what 'slides' contain, what 'device' and 'preset' refer to, or the purpose of color parameters. With low schema coverage, the description fails to compensate for undocumented parameters.

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 the tool's purpose: 'Generate multiple screenshots at once' which is a specific verb+resource combination. It distinguishes from the sibling 'generate_screenshot' by specifying batch capability. However, it doesn't specify what kind of screenshots (e.g., from slides, devices) or the exact resource being generated.

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 usage context through 'PRO feature - $4.9/mo', suggesting this requires a paid subscription. However, it doesn't explicitly state when to use this vs. the sibling 'generate_screenshot' (single vs. batch), nor does it mention prerequisites like needing an active subscription or when batch processing is appropriate.

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