gold_etsy_grade_listing

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

With no annotations, the description carries the full burden and does disclose meaningful traits: the grading is 'pure logic' that reimplements eRank/Marmalead logic rather than calling those services, it returns a fix list, and it requires BYOK and a paid PRO subscription. It does not explicitly state whether the operation is read-only or has side effects, though grading implies a non-destructive audit.

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?

About 30 words deliver the grade, criteria, logic source, fix list, auth, and cost. The 'steals' phrasing is cryptic jargon and the capitalized 'BYOK. PAID ONLY PRO $29.' tail reads like ad copy, but nothing is redundant or 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?

For a single-parameter tool with no annotations and no output schema, the description covers purpose, grading criteria, deliverable (fix list), and access constraints. The main gap is the exact return shape — an agent cannot tell whether the result is a single letter, per-criterion scores, or a structured JSON object.

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% and the description never mentions listing_id, its format, or how it is resolved, so it fails to compensate for the low coverage. Meaning must be inferred entirely from the parameter name and the 'one listing' phrase.

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 states a clear action (SEO grading) with a specific resource (one Etsy listing) and a concrete output (A-F grade plus fix list). The grading criteria are enumerated (13 tags, keyword-first title, desc depth, photos≥8, materials), and 'one listing' distinguishes it from the sibling gold_etsy_bulk_grade_shop.

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 scope ('one listing') implies single-listing audit use, and the 'PAID ONLY PRO $29' / 'BYOK' text states access preconditions. However, no alternative tool is named explicitly and there is no when-to-use versus when-not-to-use guidance relative to siblings like gold_etsy_bulk_grade_shop or gold_etsy_get_listing.

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