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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real value by declaring the return shape (per-platform counts plus an overall severity), which matters since there is no output schema, but it says nothing about cost, freshness, or whether the summary is a cheaper alternative to full validation.

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 tightly written sentences with the payload description front-loaded and the usage cue second. There is no filler, restatement of the title, or hedging.

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 one-parameter read-only tool with no output schema, the description covers what comes back and when to reach for it, which is nearly everything needed. The only real omission is an explicit comparison against the get_validation sibling and a clarification of the feedId parameter.

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% and the single required feedId has no description in the schema. The description says 'for a feed', which weakly implies the parameter's role, but it never explains that feedId is the feed identifier or what form it takes, so it only marginally compensates for the coverage 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?

States a specific resource and content: a condensed validation-status view with passing/failing/warning counts per platform plus overall severity. The word 'condensed' implicitly contrasts with the fuller get_validation sibling, but that sibling is never named, so an agent must infer the distinction.

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?

Gives a clear usage context: use it for a fast 'is this feed shippable' check before suggesting next steps. It does not state when to prefer the detailed get_validation instead, so the routing decision between the two is left partly to inference.

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