SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve? Creating high-quality AI agent skills requires consistent structure, security hardening, objective evaluation, and trigger tuning, which is difficult to do manually and consistently across platforms like Claude Code, Cursor, and OpenAI Codex. ## Core Features & Use Cases - Skill Scaffolding & Authoring: Generate standardized skill directories with SKILL.md, scripts, references, assets, and evals using init_skill.py and archetype patterns (workflow, cli-tool, hybrid). - Benchmarking & Evaluation: Run parallel with-skill vs baseline evals, grade outputs with grader subagents, and aggregate pass rates, timing, and token statistics into benchmark reports. - Trigger Optimization & Packaging: Optimize frontmatter descriptions against train/test query splits with run_loop.py, then package skills into portable .skill archives for cross-agent deployment. - Use Case: After completing a complex workflow in a session, ask the agent to distill it into a reusable skill, benchmark it against a baseline, and deploy it to your preferred agent platform. ## Quick Start Turn the workflow we just completed into a reusable skill and benchmark it against a baseline run.

Frequently Asked Questions about skill-creator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a new AI agent skill from scratch?

Run the init_skill.py script with a skill name, target path, and archetype (workflow, cli-tool, or hybrid). It generates a SKILL.md with frontmatter, helper scripts, references, assets, and an evals.json file ready for implementation.

How do I benchmark a skill against a baseline?

Define eval cases in evals/evals.json, then run with-skill and baseline subagents in parallel for each case. Grade outputs with the grader agent and aggregate results using aggregate_benchmark.py to get pass rate deltas, timing, and token statistics.

Which agent platforms support these skills?

Skills can be installed to Claude Code, OpenAI Codex, Cursor, Gemini CLI, Antigravity, Windsurf, Trae, Hermes, and Continue.dev. Each platform has a standard installation path such as ~/.claude/skills/ or ~/.codex/skills/.

How do I improve a skill's trigger description accuracy?

Curate about 20 positive and negative queries, then run the run_loop.py optimization script. It splits queries into train and test sets, evaluates triggering accuracy, and mutates the frontmatter description to reduce false positives and negatives.

What security rules must agent skills follow?

Skills must contain no hardcoded secrets, redirect script output to files, enforce rate limiting with backoff, quarantine user input against prompt injection, and run cross-platform. The quick_validate.py script checks compliance before deployment.
