render

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 implies a mutation ('fix') but does not state whether it modifies world/save state, requires elevated permissions, invalidates caches, or is safe to call repeatedly. None of the side-effect profile is disclosed.

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 short sentence with no filler, and the operative action is front-loaded. It is appropriately sized, though the terseness contributes to the purpose ambiguity rather than resolving it.

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 no annotations and no parameter documentation, the description is the only source of behavioral information, and it provides none. The existence of an output schema excuses not describing return values, but scope, side effects, and usage context are all missing.

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 takes zero parameters and the schema is empty, so there is nothing for the description to document; the baseline for a parameterless tool applies.

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 gives a verb ('Fix') and a resource ('glitched chunk rendering'), which is more than a tautology of the name 'render'. However, it is ambiguous whether the tool renders, repairs, or refreshes chunk data, and it does not distinguish itself from rendering-adjacent siblings such as preview_build_plan or snapshot. Purpose is implied but not sharply defined.

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 when-to-use guidance, no prerequisites, and no mention of any alternative tool among the many siblings. The agent is left to infer that this is for visual glitches only.

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