Generate Etsy titles

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

Annotations already declare readOnly, non-destructive, idempotent behavior, so the safety profile is covered. The description adds valuable output constraints (length caps, special-character limits) that go beyond the annotations, but says nothing about determinism or failure modes. Solid but not rich.

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?

One tight sentence that front-loads the output shape, then lists variant types and formatting constraints. No filler or repetition.

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?

Describes the output shape and formatting rules, which is the most important context for a generation tool. No output schema exists, so the description must explain return values, and it does so only partially (variant types and character rules, but not ordering or which variant is recommended). Missing sibling routing guidance for a crowded tool family.

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 67%, with keywords, modifiers, digital, and several attributes already documented in the schema. The description adds the branding/brand-variant rationale and implies how modifiers are gated, but does not explain the interplay of attributes versus keywords, which is central to output quality. Baseline 3 for a schema that carries most of the load.

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 (build) and resource (Etsy title variants) with the exact output shape (3-4 variants). Names four distinct title strategies, which distinguishes it from siblings like generate_tags and generate_description.

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 the Etsy-listing context and the output format, but the description never states when to call this versus generate_tags, generate_description, or suggest_long_tail. No explicit alternatives or exclusions are given.

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