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

No annotations are provided, so the description carries the full burden. It does disclose the return format (markdown plus canonical URL) and the content structure, which is genuinely useful. It does not state that the call is read-only, nor what happens if a non-Sunday date is supplied or if no digest exists for that week.

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?

Front-loaded with the resource name and cadence, then the content inventory, then the return format — a sensible order with no filler. It is a single dense sentence, and phrases like 'as a long-form print edition' are slightly ornamental but still convey format.

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-required-parameter read-only retrieval tool with no output schema, the description covers content, cadence, and return format adequately. Only the lack of routing guidance relative to the daily/briefing siblings and the absence of a read-only statement keep it from being fully complete.

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 100%, so the single date parameter's format, optionality, and default are already fully documented in the schema. The description's mention of Sundays loosely reinforces that dates should align to the weekly cadence, but adds no new syntax or constraint detail beyond the schema. Baseline 3 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 names a specific resource (the LexRegPulse Weekly Intelligence Digest) and states its cadence (Sundays) and content sections, which implicitly separates it from the daily siblings. It never uses an explicit retrieval verb, but the resource and cadence are unambiguous enough that an agent can distinguish it from get_daily_briefing or get_blog_posts.

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 when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. With get_daily_briefing, list_briefings, and get_upcoming_deadlines in the same family, the agent gets no routing signal about why it would pick the weekly digest over those. The Sunday cadence is descriptive, not directive.

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