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

With no annotations, the description carries the full behavioral burden. It discloses the returned fields and the point-in-time nature of the snapshot, which is useful. However, it says nothing about behavior for unknown/invalid UUIDs, auth requirements, or rate limits.

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 sentences with zero waste. The core scope (one feed, by UUID) is front-loaded, followed by the sibling-routing clause; every clause 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 simple single-parameter read tool with no output schema, listing the returned facets and the disambiguation from two siblings covers nearly everything needed. The only gap is behavior on invalid or unknown UUIDs.

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 description coverage is 100% and the single feedId parameter is already documented as an Oracle feed UUID with a format and pattern. The description restates 'by its UUID' but adds no syntax or constraint detail beyond the schema, so baseline 3 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 (Get), resource (oracle feed health), and scope limitation (ONE specific feed by UUID), and enumerates the returned facets: consecutive failures, last success/failure, status. It explicitly distinguishes itself from sibling tools get_oracle_health and get_feed_freshness.

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?

It gives explicit alternatives with the condition that selects each: use get_oracle_health for ecosystem-wide health by date, use get_feed_freshness to scan freshness across many feeds. An agent can route correctly without inference.

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