device_bulk_create

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose two useful traits — the 1024-item cap and the skip-existing-addresses behavior — which go beyond what 'bulk create' alone implies. However, it remains silent on partial failure semantics (whether an invalid address aborts the batch or is skipped) and on what is returned, leaving meaningful gaps for a mutating bulk operation.

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 tight sentences with zero filler: the first states the core action and the second adds the key behavioral nuance. The most decision-relevant information (what, how, limit) is front-loaded.

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?

The core facts needed to select and invoke the tool are present — what is created, how addresses are passed, the limit, and skip behavior. But with no output schema, nothing hints at what the caller receives back (e.g., counts of created vs. skipped) or how partial failures are handled, which an agent orchestrating a large batch would reasonably want to know.

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%, so all four parameters (unitId, networkId, networkAddrs, profile) are already documented in the schema. The description's 'max 1024' and 'address list' merely echo the schema's networkAddrs description rather than adding new parameter-level meaning, so the baseline 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?

The description states a specific verb and resource ('Bulk create devices') plus the mechanism ('by address list'), making the tool's role unambiguous. The 'Bulk' prefix differentiates it from the single-device sibling device_create, and the 'address list' mechanism implicitly contrasts it with device_range_create. An agent can tell what this tool does without opening the schema.

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 usage context is implied — use when creating many devices from an address list up to 1024 — but no alternatives are named and no when-not-to-use conditions are given. Close siblings like device_range_create and device_create overlap in purpose, yet the description never explains when to prefer one over the other.

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