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

With no annotations, the description carries the full burden and meets it: it discloses memory-only storage, auto-stop after 30s idle or 120s total, export stopping capture, and clear erasing immediately. This is far beyond typical tool descriptions.

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 compact 4 sentences that front-load the purpose and then systematically cover lifecycle and export options. No filler 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?

This is a complex, stateful tool with 5 actions, yet the description covers the full lifecycle, timeout behavior, and export paths. An output schema exists, so return-value documentation is unnecessary.

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%, so the baseline is 3. The description repeats the action flow already in the schema and only lightly summarizes export/drag-drop semantics; it adds little beyond the schema's detailed parameter descriptions.

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 opens with 'Create a short, memory-only GIF of browser work,' clearly stating the tool's purpose and key characteristic (memory-only). This distinguishes it from all sibling browser automation tools, none of which record GIFs.

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?

It provides an explicit workflow: 'Call start_recording, use browser tools normally, then call export' and clarifies that export auto-stops capture. It also explains when to use status, stop_recording, and clear, giving clear action boundaries.

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