A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds genuinely new behavior: results are sorted newest first, today is included, and only summary fields (date, title, hero line) are returned rather than full brief bodies. That last point is a useful disclosure about result shape not encoded in the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that front-loads what is returned and then the filter detail — no filler. It is dense, packing purpose, ordering, returned fields, and parameter bounds into one colon-delimited construction, but every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description need not explain return values, and it still clarifies the summary-level fields and sort order. The sole parameter is fully specified, annotations cover the safety profile, and no prerequisite or behavioral gap remains for a simple read-only listing tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry the burden and it does: it defines the valid range (1 to 30), the default (7), and the inclusive counting semantics (today included). That fully documents the single parameter beyond the bare 'integer, default 7' in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Names a specific verb (list) and resource (recent editions of The 07:00 Brief) and enumerates the returned fields, so the agent knows it is a browse/list operation rather than the single-item retrieval implied by the get_* siblings. It never names a sibling or states the contrast explicitly, so sibling differentiation is inferred rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Ordering ('newest first'), the day window, and the default give clear context that this is for browsing recent editions. However, it never says when to prefer this over get_morning_brief for full content, nor any exclusion or prerequisite, so the usage guidance remains implied.

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