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

With no annotations, the description carries the full burden and does disclose the safety profile ('Read-only; sends nothing') plus the auth requirement (API key) and the report's content categories. It stops short of describing return format or ordering, but for a parameterless read-only tool this is solid disclosure.

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?

A single dense sentence that front-loads the core purpose (7-day summary) and then compresses the contents, followed by short safety/auth clauses. Every clause carries information, though the list-like density is slightly heavy.

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?

Given zero params, no annotations, and no output schema, the description is the sole source of information and it covers content, safety, side effects, and auth. It omits sorting/timezone/pagination details, but those are minor for a fixed-window weekly summary.

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 clarify; the 4 baseline for zero-parameter tools 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?

States a specific verb+resource ('Plain-English summary of the last 7 days') and enumerates the report's contents (memory checks, warnings, offloaded/ran jobs by provider, minutes, failures), so the agent knows exactly what it produces. It does not name a sibling to distinguish from, so it falls short of 5.

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?

Usage is only implied by the weekly framing, and the prerequisite 'Needs an API key' is stated, but there is no explicit when-to-use vs. when-not guidance and no routing against the adjacent usage_and_upgrade or check_memory tools.

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