get_bot_status

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real context by specifying the transport ('over Bluetooth') and that the target is a preconfigured device, implying a local connection requirement. It does not mention what happens if the bot is out of range or unpaired, which is the main behavioral risk for a Bluetooth read.

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?

A single sentence with no filler, front-loading the verb and the returned data. Every word (battery, firmware, mode, Bluetooth, configured) carries information.

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?

With no input parameters and no output schema, the description usefully enumerates the fields returned (battery, firmware, mode) so an agent knows what it gets. It stops short of describing the response shape or failure behavior over Bluetooth, which is the only remaining gap for such a simple tool.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The description correctly implies the target is implicitly 'the configured' device rather than something passed in.

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 ('Read') and a specific resource ('the configured SwitchBot's battery, firmware and mode'), which lets an agent distinguish it from get_device_health or get_display_status. It does not explicitly name which sibling to prefer for a general device check, so it falls short of a 5.

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 only implied: it reads status of 'the configured' SwitchBot, suggesting it applies to the paired bot rather than an arbitrary device. There is no explicit when-to-use vs. when-not guidance and no mention of alternatives such as get_device_health.

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