render_frame

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

Annotations already indicate destructiveHint=true and readOnlyHint=false. The description only adds 'write_still', which effectively restates the write nature without disclosing file overwrite behavior, side effects, or permission needs.

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 short with no fluff, but it is under-specified rather than meaningfully concise. It conveys the core action but omits essential context, so it is not optimally structured for tool selection.

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 tool with one parameter, an output schema, and annotations, the description is incomplete: it lacks parameter semantics, usage guidance, and behavior beyond the annotation basics. A minimal viable description should provide at least some context about the filepath and when to use this 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 sole parameter 'filepath' has no schema description and the description provides zero explanation of its meaning, format, or usage. With 0% schema coverage, the description fails to compensate for the missing parameter information.

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 'Render frame saat ini (write_still)' clearly states the tool renders the current frame, with 'write_still' indicating a file-writing operation. It is specific but does not differentiate from sibling tools like 'render_viewport_to_path'.

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 gives no guidance on when to use this tool versus alternatives such as 'render_viewport_to_path' or other render-related tools. There are no usage conditions or exclusions mentioned.

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