smugmug_type

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

With no annotations, the description carries the full behavioral burden and falls short: it does not say whether typing replaces or appends to existing field contents, whether it triggers form submission or validation, what happens if the field number is invalid, or whether page focus/state is required. These are exactly the behaviors an agent needs to avoid corrupting a form.

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?

A single front-loaded sentence with no filler, and the resource scope is stated early. The brevity is close to overly sparse for a mutation-style action, but nothing is redundant.

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 tool with a fully described schema and no output schema, the definition covers the essentials at a minimum-viable level. It is still missing the read-before-type sequencing and the replace-vs-append behavior, which matter given the absence of annotations.

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%, so both parameters are already self-documenting ("Text to type", "Field number from the last read"). The description's "numbered field" merely restates the element parameter and adds no format or constraint detail 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?

"Type text into a numbered field" gives a concrete verb and target, and "on the current SmugMug page" scopes the resource to the active page. An agent can distinguish it from smugmug_click and smugmug_read without opening the schema, though the description never names those siblings explicitly.

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?

Usage is implied by "numbered field" — the agent infers it should call smugmug_read first to learn field numbers — but this prerequisite is never stated. There is no explicit when-to-use/when-not-to-use guidance relative to smugmug_click or smugmug_open.

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