dat_browse_screenshot

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

No annotations provide safety or behavioral cues. Description mentions 'completed' prerequisite but does not disclose potential errors, size limits, or whether multiple calls are safe. Basic behavioral info is present but incomplete.

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?

Single sentence is concise and front-loaded with main action. No wasted words, though could be slightly more structured (e.g., separate output format).

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 simple download tool with no output schema, description covers core function and params but misses details like base64 encoding format, error handling, or any prerequisites beyond task completion.

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% with both parameters described. Description adds minimal value beyond schema, only hinting to get filenames from browsing result. Baseline score appropriate.

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?

Description clearly states action (download), resource (screenshot from browsing task), and output format (base64). Distinguishes from sibling tools like dat_browse (starts task) and dat_browse_status (checks status).

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?

Description implies use after task completion but lacks explicit guidance on when to use vs alternatives, such as referencing dat_browse_status to check completion first.

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