get_feature_freshness

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

No annotations are provided, so the description carries the full burden. The verb 'Get' and 'showing last materialization time' imply a non-mutating, read-only operation, and the output fields are stated. But the description does not disclose possible failures, time/format caveats, or whether the data may be cached or delayed.

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?

The description is one compact sentence with no filler. The action, scope, and the two key output fields are all front-loaded and each part earns its place.

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-parameter read-only getter, the description is mostly complete: it names what is retrieved and what is returned. It leaves unstated exactly how staleness is represented and what happens when no feature views exist, but these are minor in light of the tool's simplicity.

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?

There are zero parameters, and the schema coverage is 100%, so no parameter documentation is needed. The description still adds semantic value by defining the scope ('all feature views') and the relevant output dimensions ('materialization time and staleness').

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 uses a specific verb and resource: it says it 'get[s] freshness status of all feature views' and explicitly names the output ('last materialization time and staleness'). This clearly separates it from sibling tools like get_feature_views, get_feature_view_details, and get_feature_store_stats.

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?

The intended use is implied: call this when you need freshness/staleness across all feature views. However, it does not explicitly state when to avoid it or name alternatives such as get_feature_view_details for a single feature view, so the usage guidance is not fully developed.

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