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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is fully covered. The description adds a meaningful behavioural detail — this is the customer-facing rendering, mirroring the Weekly Report page — but says nothing about freshness, period boundaries, or return shape.

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?

Two short sentences, front-loaded with what the artefact is before the parity note. Every clause carries information; the 'Mirrors the Weekly Report page' sentence is only marginally load-bearing but does orient the agent to the UI equivalent.

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 output schema, the description carries the burden of conveying what comes back. The three-item summary (what moved, what was published, what to do next) gives a useful sketch of the sections, but the format, granularity, and whether the content is per-brand or cross-brand are left unspecified.

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 of 4 applies; there is nothing for the description to disambiguate. It is silent on parameters, which is harmless here.

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-free but concrete resource — the weekly report as the customer receives it — and enumerates its contents (what moved, what was published, what to do next). It also anchors it to the Weekly Report page. It does not name or contrast any sibling, but none of the listed siblings (my_traffic, my_visibility, generate) is a close substitute, so the lack of differentiation costs little.

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 explicit when-to-use guidance, no prerequisites, and no statement of when an agent should prefer this over neighbours like my_traffic or my_actions. Usage is only implied by the tool name and the 'as the customer receives it' framing.

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