set_renderer_paused

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

With no annotations, the description carries the full behavioral burden but only implies a state mutation. It does not say whether the pause affects all viewers or the realm, whether it requires an active render session, or how pause state interacts with later renders or restarts.

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 front-loaded sentence with no filler, which suits a small toggle tool. It is arguably too terse given the unexplained second parameter, but there is no wasted verbiage.

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 described, but for a state-mutating renderer tool with zero annotation coverage and 0% parameter documentation, the description omits too much. The agent cannot tell what scope 'active' covers or what the viewer argument does.

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 compensate for two undocumented parameters. It only loosely maps to 'paused'; the 'viewer' parameter is never explained, leaving the agent unable to know whether it targets a specific viewport or the whole delegate. Default values (paused=true) are left to the schema.

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 concrete verb pair ('pause or resume') and a specific resource ('the active LOP Hydra delegate'), so an agent knows the operation. It does not, however, distinguish itself from close siblings such as restart_renderer or set_hydra_renderer, which could plausibly affect the same delegate.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives like restart_renderer or set_hydra_renderer. The agent is left to infer usage entirely from the name and one sentence.

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