device_activate

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

Annotations already mark this as destructive, and the description adds valuable behavior beyond that: activating via ABP or resetting an OTAA session, plus the network-key defaulting rule. No contradiction with the destructiveHint annotation.

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 convey the core operation, the alternative use case, and a protocol-specific key rule. No filler or redundancy.

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 destructive 9-parameter activation tool with 0% schema description coverage, the description is too thin. It lacks meaning for most required parameters, does not explain format expectations, and gives no guidance on prerequisites or side effects beyond the key default.

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 carries the burden for explaining parameters. It only clarifies the nwk_s_enc_key defaulting relationship; required parameters like dev_eui, dev_addr, and app_s_key, plus counter semantics, are left unexplained.

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 uses a specific verb and resource: 'ABP-activate a device (or reset an OTAA session)'. This clearly identifies the operation and distinguishes it from siblings like device_deactivate or device_set_keys.

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 gives clear context for when the tool applies: ABP activation or OTAA session reset. It also provides conditional guidance for LoRaWAN 1.0.x key handling, though it does not explicitly name alternatives or exclusions.

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