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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds valuable behavior beyond that: outputs are separated into clones and teens, prices differ and must never be summed, and passing 'strain' produces a dated one-sentence summary. No contradiction with annotations exists.

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 front-loaded with the core status list, and every sentence carries useful information, including the critical 'never add them together' caveat. It is somewhat dense with colon-separated details, but no sentence is wasted.

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 fully takes on the burden of explaining return semantics: clones and teens lists, one row per strain, links, and the optional strain-specific summary. The tool has no required parameters, and the optional input behavior is thoroughly described.

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 100% and the single optional 'strain' parameter is already documented as accepting menu slug, encyclopedia slug, or name/alias. The description adds meaning by explaining that passing it returns a dated summary including associated teens, which is useful beyond the schema.

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 clearly identifies the operation ('Live stock status for every strain listed on /live-inventory in one call'), the resource, and the status vocabulary (InStock / PreOrder / OutOfStock). It also distinguishes the clones and teens product lines, making it distinguishable from siblings like get_teen_inventory.

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 description gives clear usage context: use this for a full availability snapshot, report both clones and teens when asked, and pass 'strain' for a single-strain summary. It does not explicitly name alternatives or say when not to use this tool, so it stops short of a full 5.

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