lw_ble_connection_list

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

No annotations are provided, so the description carries the full behavioral burden, yet it only states that all sessions are enumerated. It does not disclose whether stale or inactive connections are included, whether the call can block, or any failure/auth conditions, leaving the agent largely uninformed about behavior.

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?

It is a single efficient sentence with no filler and the listing operation is front-loaded. It borders on under-specification rather than verbosity, which keeps it just short of a 5.

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 zero-parameter, read-only list tool with an output schema documenting returns, the description is minimally sufficient. It does not, however, explain what constitutes a 'session' or how the list relates to the connection/status/subscription siblings, which are the main open questions.

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 the baseline is 4 per the rubric. There is nothing for the description to clarify beyond the schema, which is fully specified.

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 pairs a specific verb ('Enumerate') with a resource ('every session the server currently holds'), so an agent can tell this is a read-only listing operation. However, it says 'session' while the tool name and siblings use 'connection', and it does not distinguish itself from lw_ble_connection_status or the other *_list siblings.

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 guidance on when to call this versus lw_ble_connection_status (single connection detail) or lw_ble_subscription_list / lw_ble_scan_list. The listing intent is only implied by the verb 'Enumerate', and no prerequisites or exclusions are given.

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