Inspect After Effects Render Templates

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is established. The description adds meaningful behavioral context beyond that: it reads from the first existing render-queue item and explicitly disclaims queue/render side effects.

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 tight sentences deliver the core purpose and a key exclusion with no filler. The primary behavior is front-loaded, and the negative guarantee adds value without bloating the description.

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 zero-parameter read-only inspection tool with a full output schema and strong annotations, the description is sufficient. It identifies the data source, the type of data returned, and the critical non-behavior (no queueing/rendering), so an agent can invoke it correctly without further clarification.

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 tool has zero parameters and an empty input schema, so there are no parameter semantics for the description to clarify. The description correctly omits parameter detail and the schema is already unambiguous.

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 names a specific verb ('Read'), resource ('render and output-module template names'), and source ('first existing After Effects render-queue item'). It also draws a clear line against queueing or rendering, which distinguishes it from sibling tools like enqueue_after_effects_render and preview_after_effects_render.

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 clearly implies when to use it: when the agent needs template names without triggering a render. It also states a firm exclusion ('never queues or renders'), but it does not explicitly name alternative sibling tools or spell out conditions for choosing a different inspection tool like inspect_after_effects_template_source.

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