production.character_capture_candidate_views

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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=false, so the agent knows this produces artifacts without destroying data. The description adds the meaningful constraint that the render must match a stored reference exactly, implying determinism for later comparison. It does not say where renders are written, whether existing outputs are overwritten, or what happens if the reference set is missing.

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?

A single tight sentence with the key qualifier front-loaded; no filler. Slightly loose in using the word 'look', which is conversational rather than precise, but nothing is wasted.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. But for a render-producing tool with three undocumented parameters, the description omits prerequisites (an existing reference set), output location, and the relationship to the capture/compare siblings — gaps the structured data does not fill.

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 description coverage is 0%, so the description must carry parameter meaning. It clarifies 'reference_set' (the stored camera/resolution/look set) and implicitly 'object_name' (the candidate to render), but 'operation_id' is never mentioned and no format, naming, or path conventions are given.

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?

States a specific verb ('Render') and resource ('a candidate'), plus the exact framing ('the cameras, resolution and look of a stored reference view set'), which distinguishes it from production.character_capture_reference_views and production.character_compare_reference. However, it never names those siblings explicitly, so differentiation must be inferred from the name-plus-description pair.

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 explicit when-to-use, when-not-to-use, or named alternative. The reader can infer it belongs to a reference-comparison workflow after a view set is stored, but the description never says a reference set must already exist or points to production.character_compare_reference as the follow-up step.

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