render_job_add

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

No annotations are provided, so the description carries the full burden. It discloses that the job captures current settings at the moment of addition, which is useful. It does not mention side effects, return behavior, or permissions, which is acceptable for a simple additive 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?

Two short sentences with no wasted words. The first sentence states the core function, and the second provides a critical prerequisite. Perfectly front-loaded and efficient.

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?

The description adequately covers the tool's purpose and prerequisites. However, it does not mention return values or error conditions. Given the tool's simplicity (zero parameters), it is moderately complete but could be improved by noting expected output or confirmation.

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 zero parameters, so schema coverage is 100%. Per rubric, a baseline of 4 is appropriate when no parameters exist. The description does not add parameter info because none are needed.

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 action: 'Add a render job for the current timeline using the current render settings.' This distinguishes it from siblings like render_start (which begins rendering) and render_job_delete (which removes jobs).

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 explicitly advises to set format, codec, and settings before calling, implying a prerequisite. However, it does not explicitly state when to use this tool versus alternatives (e.g., quick_export for quick exports).

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