Listing Preflight — AI Skill Pre-Submission Check

Lists the rejection causes in your AI skill listing, sorted by what to fix first. Paste your SKILL.md, title, description, examples, price and ZIP file list, and get known rejection causes, mismatches between the listing and the package, and what could not be checked. Each finding names its source and a concrete fix. It reduces avoidable rejection causes; it does not guarantee approval.

What it checks

First reply — a skill that opens with questions and produces nothing can fail a reviewer's test run
Examples vs output — listed examples that don't match what the skill actually produces
Files — docs that point to files missing from the ZIP, internal working files, unfinished content
Frontmatter — name and description limits for the Agent Skills format
Title and fields — PromptBase's 40-character title and removed symbols, Capafy's field limits
Promises — "passes review", income claims, other outcomes the skill cannot keep
Pricing wording — tier names on a one-price listing
Buyer docs — another store's name in install steps, unfinished support lines
Pasted material — secrets (never quoted back) and instructions aimed at the checker

How the report is organized

Fix before you submit → Fix to avoid buyer confusion → Polish → Not checked → Checked with no findings → Rule freshness. Every finding says where, what, why (tagged [official], [field record], [third-party report], or [preflight check]) and a short fix.

Built from real rejections

The [field record] rules come from the seller's own submissions in September 2026, written up in references/rejection-cases.md. Every rule's source and check date is in references/platform-rules.md.

Included files

SKILL.md · references/platform-rules.md · references/rejection-cases.md · usage-guide.md · examples/ (a flawed listing with its full report; a quick self-check) · README · LICENSE · DISCLAIMER

EU AI Act Readiness Audit

Selling AI into Europe? Since Aug 2026, the EU AI Act enforces transparency duties with fines up to 15M euros or 3 percent of turnover (per Article 99, as of Oct 2026). This skill classifies every AI system you use into prohibited, high risk, limited risk, or minimal with a written keyword table you can inspect, then writes your inventory register, a deadline ordered obligations checklist, and an AI literacy training log. Planning help, not legal advice.
