set_niagara_system_warmup_tick_delta

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=true, so the mutation contract is covered structurally. The description adds value by disclosing the return payload (old vs new value, applied, saved) despite there being no output schema, but it says nothing about whether edits are persisted to disk or require specific asset permissions.

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, purpose front-loaded before the return contract, with no filler. The Returns block is compact and earns its place given the absence of an output schema, though the fields are dense and unpunctuated.

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 two-parameter setter with full schema coverage and strong annotations, the main remaining gap is disambiguation from sibling warmup-setters and any note on persistence. The return-value description compensates for the missing output schema, making the definition adequate but not complete.

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%: system_path is documented as an asset path and warmup_tick_delta already states 'seconds (must be > 0)'. The description's '(seconds per tick)' mostly restates the schema rather than adding new semantics, so the baseline of 3 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?

States a specific verb+resource ('Set the warmup tick delta ... on a Niagara system') and clarifies units ('seconds per tick'), so it is distinct from a generic property setter. It does not, however, distinguish itself from close siblings such as set_niagara_system_warmup_tick_count or set_niagara_system_warmup_time, leaving that inference to the reader.

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 statement of prerequisites, and no naming of the warmup_tick_count/warmup_time alternatives that an agent must choose between. The description only says what the tool does, not when an agent should reach for it over its siblings.

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