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

Beyond the annotations, the description discloses credit consumption, authorization requirements, entitlement-dependent downloading, idempotent behavior for repeated planId calls, immediate return semantics, and variable render timing. This is substantial behavioral context for an open-world, non-read-only tool.

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 front-loaded with the authorization requirement, then credits, plan consumption, entitlement caveat, idempotency, and async status guidance. Every sentence contributes operational information without repetition.

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?

With one required parameter, no output schema, and annotations that establish the safety profile, the description covers the remaining essentials: auth, billing, idempotency, async behavior, status-checking, and download entitlement caveats.

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% and the planId definition already says it comes from plan_transparent_video. The description adds useful semantics by explaining that the planId is consumed and that repeated calls with the same planId are idempotent.

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 a specific verb and resource: it consumes a plan from plan_transparent_video and starts a transparent-video render. It clearly distinguishes this create/start operation from the planning sibling plan_transparent_video and the status-checking sibling get_render_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?

It gives explicit prerequisites: an approved AlertForge connection and OAuth-style authorization. It also explains when creation is allowed versus downloading, states that credits are spent, and directs the agent to get_render_status after the immediate return.

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