AI Agent Skills Marketplace

Turn OpenAPI specs into exhaustive, framework-ready test suites covering happy paths, edge cases, and security gaps.

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

Writes clear pull request descriptions by analyzing your branch diff. Covers what changed, why, how, and what to test. Works with GitHub, GitLab, and Bitbucket.

Enforce senior-level coding standards with a focus on verification, minimal diffs, and evidence-based bug fixing.

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

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

Bypass OS-native file upload dialogs in browser automation using JavaScript interception and DataTransfer injection.

Upgrade your AI agent with a senior-level engineering SOP focused on inspection, minimal diffs, and hard verification.

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.

A research-backed strategic decision-making toolkit for scenario planning, stress-testing, and investor-grade scoring.

Automated test generation with edge case analysis and framework-native syntax for TS, Python, Go, and Rust.

Audit your AI agent's evaluation coverage to identify missing release gates and production risks.

Generate realistic JSON or CSV test data from plain-English schema descriptions with up to 1,000 rows.

Design, debug, and harden AI control loops with explicit contracts and automated verification harnesses.

The "Skill for building Skills": Automate creating, testing, and optimisation of custom workflows.
