get_lords_journal_content_dates

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

With no annotations, the description carries the full behavioral burden. It clearly indicates a list-style read operation and says it returns dates where Journal data exists, but it does not state whether the operation is side-effect-free, how missing dates or empty ranges behave, or any rate/auth constraints.

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 key purpose and usage note are front-loaded and easy to scan. There is minor redundancy: the return behavior is stated twice and the sibling is referenced twice, but the description remains appropriately sized.

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 simple read/list tool with an output schema, the description is nearly complete: it covers purpose, usage context, both parameters, and the return concept. The main missing piece is optional date-boundary behavior when start_date or end_date is omitted.

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 coverage is 0%, so the description must explain the parameters, and it does: start_date and end_date define the date range, with YYYY-MM-DD format specified. It does not explain optionality or what null/default values mean, leaving a small gap.

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: it lists dates that have Lords Journal data and clarifies those are sitting/proceedings dates. It explicitly distinguishes this from the sibling get_lords_journal_sittings by framing this tool as the date-discovery step before calling that tool.

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 context: use it to find which sitting dates have Journal content before calling get_lords_journal_sittings. It names the alternative but does not state when not to use it or any edge exclusions.

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