set_niagara_system_warmup_tick_count

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

Annotations already declare destructive=true, idempotent=true and non-read-only. The description adds real context beyond that: the operation is a derived re-resolution rather than a direct set, 'protected' hints at a constrained property, and the returned applied/saved flags tell the agent the change is applied and persisted. It does not explain why the operation is flagged destructive.

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?

Two sentences, front-loaded with the core action, plus a structured Returns block. Dense with engine jargon but every element earns its place; no filler.

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?

No output schema exists, but the description compensates by enumerating the full return payload (old/new tick counts, warmup time/delta, applied, saved), which is exactly what an agent needs to interpret results. For a one-parameter tool the coverage is solid, though the destructive/idempotent workflow context could be richer.

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 100% for the single system_path parameter, so the schema already carries the meaning. The description adds nothing further about the parameter's path syntax or constraints, making the baseline 3 correct.

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+resource (re-resolve UNiagaraSystem::WarmupTickCount) and explains that the value is derived from the WarmupTime/WarmupTickDelta pair, which meaningfully ties it to its sibling setters. It never names those siblings explicitly (set_niagara_system_warmup_time, set_niagara_system_warmup_tick_delta), so the differentiation is implied rather than stated.

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?

Usage is implied: 're-resolve ... from the current WarmupTime/WarmupTickDelta pair' suggests calling this after the time/delta are changed. But there is no explicit when-to-use, when-not-to-use, or routing to the sibling warmup tools, so an agent must infer the workflow.

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