Dump Raw BaseContainer

get_container
Read-only

Dump raw Cinema 4D BaseContainer data, including hidden keys, to inspect internal settings. Filter by key range to narrow results.

Instructions

Dump the raw BaseContainer of a C4D entity (including hidden keys that don't show up in describe, e.g. Octane AOV shader slots at 3740/3741). Filter by key range to narrow output.

  2. First observedv0.3.1

TDQS

A4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful behavioral context, that this exposes raw keys not shown elsewhere and that output can be filtered by key range. It does not go into output size, formatting, or default range behavior, but the annotation lowers the burden on the description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded, stating what the tool does in its first clause. The added example about Oct 2 AOV shader slots earns its place by clarifying why raw hidden-key access is valuable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, read-only, and its key parameter is thoroughly documented in the schema. With no output schema, the description could have included a bit more detail about the return shape, but 'dump raw BaseContainer' strongly implies what the response will contain, and the filtering guidance helps agents manage output size.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents all three parameters including the handle shape in detail. The description adds some context by calling out key-range filtering, but it doesn't meaningfully supplement the parameter semantics beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool dumps the raw BaseContainer of a C4D entity, a specific verb and resource. It also distinguishes the tool from `describe` by calling out hidden keys that don't appear there.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description indicates when to use this tool, specifically when raw or hidden container keys are needed, and gives a concrete use example (Octane AOV shader slots). It also suggests filtering by key range to narrow output, which helps control scope. It doesn't explicitly state exclusions or direct users to alternative tools, but the use case guidance is clear enough.

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