set_enum_bitflags

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

Annotations already declare idempotentHint=true and destructiveHint=true, so the safety profile is partly covered, yet the description adds real value by spelling out the idempotency mechanics (re-setting reports already_set with applied=false) and giving the full return shape in the absence of an output schema. It omits any note on clearing behavior or compile/save requirements.

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 compact sentences plus an explicit return shape, front-loaded with the operation and asset type. Every line earns its place, though the word "Toggle" sits slightly at odds with the desired-state parameter and costs a bit of clarity.

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 mutation with annotations carrying the safety profile and 100% schema coverage, the description supplies the missing return contract and idempotency detail. The only real gap is the absence of any compile/save or permission note for the modified enum asset.

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 coverage is 100%, so the baseline is 3, but the description adds functional meaning beyond the schema's "Desired state": bitflags=true makes enumerators combinable as flags, and the enum_path target is characterized as a UUserDefinedEnum rather than an arbitrary asset.

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 and resource: it sets the "bitflags" meta on a Blueprint Enum (UUserDefinedEnum), and explains the effect on enumerators. It does not differentiate itself from sibling enum tools (create_enum, add_enum_entry, get_enum_info), but the target asset and meta-property are precise enough to identify the operation.

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?

The description says what the tool accomplishes but gives no when-to-use guidance, no prerequisites, and names no alternative (e.g., when to use this versus generic property-setting tools). The rationale clause hints at intent but does not route the agent against alternatives.

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