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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered; the description still adds real value by disclosing in-memory processing, the secrets caveat, and how arrays/nulls are rendered as JSON textareas. It does not cover size limits or error behavior, so it stops short of full.

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?

Four short sentences, purpose front-loaded, then outputs, then edge-case behavior, then the sibling routing hint. Nothing is redundant and every sentence carries information an agent would otherwise have to guess.

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?

There is no output schema, and the description compensates by enumerating the five export formats returned. Combined with the annotations, a caller knows what it gets and that the call is safe, but the undocumented overrides parameter leaves a gap for callers wanting to customize the generated form.

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 0% across 3 parameters. The description clarifies that the required 'json' string is a serialized JSON object and hints at nested paths, but the 'overrides' parameter — by far the most complex, with path arrays up to 9 items, a type enum, labels, and required flags — is never mentioned. It only partially compensates for the coverage gap.

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 and resource ('Generate an editable form from a JSON object') and immediately enumerates the concrete artifacts produced (nested field paths, JSON Schema, HTML, React JSX, config exports). This distinguishes it from sibling generators like usesignal_generate_qr, usesignal_flowchart, and usesignal_format_json.

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?

Gives an explicit routing rule: 'To show an interactive preview, call usesignal_open_workbench with this result input,' which tells the agent the follow-up path. It also flags a usage constraint ('avoid secrets'), but no explicit when-not-to-use condition or exclusion is stated.

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