snapshot_layer_tree

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses that the snapshot includes a deterministic SHA-256 digest, but it does not clarify read-only versus mutating behavior, what exactly is captured, whether capture has side effects, or any permission/performance characteristics.

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 single well-formed sentence with no filler, and the most distinctive detail, the deterministic SHA-256 digest, is front-loaded. It is compact and easy to scan.

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 snapshot tool with no annotations and an undocumented optional parameter, the description is under-specified. The output schema can carry return-value details, but the agent still lacks guidance on what `texture_set` affects and how this tool fits into the snapshot/diff workflow.

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 single optional `texture_set` parameter has 0% schema description coverage and is not mentioned at all in the description. The description does not compensate for that gap, leaving the parameter's scope and effect unexplained.

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, "Capture", and a clear resource, "layer/effect snapshot", plus a distinguishing feature, a deterministic SHA-256 digest. It is understandable apart from siblings like `diff_layer_snapshots`, though it does not explicitly position itself relative to listing or diffing tools.

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?

There is no guidance on when to use this snapshot tool versus `list_layers`, `find_layers`, or `diff_layer_snapshots`, nor any mention of prerequisites or exclusions. The intended workflow is only weakly implied by the name.

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