AI Agent Skills Marketplace

Builds the organizational memory schema your AI agent needs to answer why — capturing decision provenance, causal chains, and event context that embedding-based retrieval permanently discards.

SEO optimizer and banned-word scanner for Chinese social media. Keyword optimization and advertising law compliance.

Catches dangerous database migrations before they hit production. Reviews schema changes for locking hazards, data loss, missing rollbacks, and index issues across PostgreSQL, MySQL, and SQLite.

Professional API design and review skill for REST, GraphQL, and event-driven architectures.

Evaluates AI coding agent platforms across five structural dimensions that determine real-world performance independently of model quality, so teams select on architectural fit rather than benchmark scores.

Evaluate market opportunities with technical decomposition, directional sizing, and measurable next-move recommendations.

Transform URLs or product lists into SEO keyword research packs with Google Ads data and intent-based clustering.

Generates a complete, polished README.md by scanning your actual project structure, dependencies, and code.

Professional security audit skill for web apps and APIs with structured severity-based findings and remediation plans.

Transform business ideas into rigorous, scenario-based execution plans with explicit assumptions and KPIs.

Professional prompt engineering, audit, and evaluation system for production-grade AI agents and workflows.

Coordinate specialized AI agent roles for complex planning, implementation, and verification workflows.

Every AI-built UI looks generic and templated. This skill teaches your agent to actually match the design to the project, the industry, and the audience.

Revenue-weighted prioritisation for solo founders. Tells you what to work on, then produces the deliverable inline — no plans, no fluff, just the next action that makes money.

Generate professional, evidence-backed CRO audits and A/B test ideas from any landing page URL.

Transform robotic AI drafts into natural, human-sounding prose with native-level flow and tone.

Eliminate the "re-entry tax" with structured state dumps that capture your focus before context switching.

Published AI benchmarks measure brains in jars. They test models in isolation or within a single reference harness — and then attribute all performance to the model. This skill teaches you to decompose agent performance into its two actual components: model capability and harness multiplier. The result is evaluations that predict real-world behavior instead of benchmark theater.
