happening_now_in_lords

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. It conveys that data is 'live'/'real-time', but says nothing about freshness guarantees, what is returned when the chamber is not sitting, auth or rate limits, or data source. For a zero-parameter live-feed tool with no annotation coverage, this is thin.

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?

The opening two sentences are well front-loaded and earn their place, but the trailing 'Returns:' block restates the first sentence almost verbatim ('Live information about current Lords chamber activity') while an output schema already exists. That repetition adds no information and could be dropped.

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 parameters and an output schema present, the description need not explain return values. It covers purpose, usage context, and sibling alternatives, so an agent has enough to invoke it correctly; only behavioral/freshness detail is missing.

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 no parameters, so there is nothing for the description to disambiguate and no schema coverage gap to compensate for. Baseline for a zero-parameter tool 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 ('Get live information about what's currently happening in the House of Lords chamber') and explicitly distinguishes itself from the near-identical sibling happening_now_in_commons. An agent can select between the two without opening either 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?

It gives a clear usage condition ('Use when you want real-time updates on Lords business, current debates, or voting activity') and names two alternatives (happening_now_in_commons, search_calendar). It stops short of saying when NOT to use this tool or which alternative to prefer for historical/date-based lookups, so it is clear context without full routing logic.

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