set_serial_title

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

With no annotations, the description carries the burden, and it does disclose the write target, the deferred 'next push' timing, and the fetch_if_empty persistence behavior. However, it does not cover response shape, error behavior, permissions, or whether an existing title is overwritten, which are clear gaps for a mutation tool.

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?

Three dense sentences, no filler, and the core action and write target are front-loaded. Each sentence adds a distinct fact: what it writes, why it exists, and when it takes effect/persistence.

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 two-parameter setter this is largely complete: it covers the target field, the per-serial scope, persistence, and the push dependency. The lack of an output schema and annotations means return/error details are absent, but the core calling context is sufficient.

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%, so the description must compensate. It does: title is explained as the per-gun WooCommerce listing title persisted to Serial No.item_name, and serial_no is the identifier for 'one firearm'/'per-serial' gun. The meaning of both parameters is recoverable, though serial_no is not formally defined.

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 opens with a precise verb-resource pair: 'Set the per-gun WooCommerce listing title for one firearm' and names the underlying field it writes (Serial No.item_name). It distinguishes this from the shared Item name, so the tool's scope is unambiguous next to siblings like woo_push_serial and woo_push_item.

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 clear context for when to use it: to give one physical gun its own title instead of the model name shared by every serial. It also tells the agent the effect is deferred to the next push, but it stops short of explicitly naming when not to use it or comparing it to a direct alternative.

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