renforge_capture_screenshot

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

With no annotations, the description must disclose behavioral traits, but it only says 'persist a screenshot,' leaving out side effects such as file overwriting, naming conventions, or whether it captures the current screen or processes an input. This is a significant gap for a write operation.

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, concise sentence with no extraneous words, front-loading the action 'Persist' and specifying a location. While efficient, it is arguably too terse given the tool's complexity, but it earns a 4 for structure.

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 13 undocumented parameters, no annotations, and a one-sentence description, the tool definition is severely incomplete. It fails to explain any parameter, usage context, or behavioral detail, making it inadequate for an agent to correctly invoke it.

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 input schema has 13 parameters with zero description coverage, and the description mentions none of them. It does not clarify the required project_path or the meaning of crop, scale, grid, or other fields, leaving the agent completely without guidance.

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 uses the verb 'Persist' to clearly indicate a save/write operation, and identifies the resource as a screenshot destined for a 'controlled capture directory.' This distinguishes it from a simple screenshot tool, though it does not explicitly name sibling alternatives like renforge_screenshot.

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 no guidance on when to use this tool versus alternatives, nor does it mention prerequisites, exclusions, or appropriate contexts. It is a bare statement without any usage direction.

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