The Jeffy AI Agent Skill allows developers to initiate an autonomous improvement loop within their projects by using the `/jeffy` command. It sets up per-project Jeffy state files and uses the loop engine embedded within a Stop hook to iteratively enhance the project's code quality.
What this skill does
Upon executing the `/jeffy` command, starts an improvement loop for the active project.
Creates and manages Jeffy state files for each project to track and control the improvement process.
Utilizes a Stop hook script located at `hooks/stop-hook.sh`, which reads the session data from `.claude/jeffy-loop.local.md` at the project's root directory.
Continuously refines project iterations until the designated budget is exhausted or completion criteria are met.
Registers globally in the `~/.claude/settings.json` file but respects project-specific settings by exiting non-configured projects immediately.
Who it is for
Software developers looking to automate project improvement tasks.
Development teams using AI coding agents such as Claude Code, Cursor, and Codex.
Technical leads aiming to enhance code quality through iterative improvements.
Use cases
Implementing automated code refinement for a software development project.
Continuously integrating and improving code based on iterative feedback loops.
Managing and tracking AI-assisted project enhancement efforts without manual intervention.
Technical details
Compatible with AI agents like Claude Code, Cursor, and Codex.
Leverages the agentic-ai and aiapplication frameworks.
Operates within the project's root directory fixed at the Claude Code startup location, ensuring consistent execution even with shell working directory changes.
Allows configuration of iteration budgets via command-line arguments, offering default and customizable options.
