What problem does it solve?

This skill helps developers and power users debug Emacs package load failures and runtime issues by connecting to a running Emacs session and using a standardized workflow.

Core Features & Use Cases

Live session inspection via emacsclient and helper utilities to expose function, variables, and buffers.
Reload edited elisp, byte-compile, inspect Messages, Backtrace, and run ERT tests to verify fixes.
Use cases include diagnosing package load errors, configuration issues, and debugging interactions with running Emacs instances.

Quick Start

Connect to the live Emacs session with emacsclient and begin the debugging sequence.

FAQPage Schema

How do I debug Emacs package load failures in a live session?▼

To debug Emacs package load failures in a live session, connect to a running Emacs instance via emacsclient. This allows interactive inspection of variables, functions, and buffers to identify and reproduce runtime issues directly.

What is the best way to inspect elisp backtraces and *Messages* when a package fails to load?▼

Inspecting elisp backtraces and *Messages* requires connecting to the live Emacs session with emacsclient. You can then view the *Backtrace* and *Messages* buffers to diagnose the root cause of package load errors.

Can I reload edited elisp and run ERT tests without restarting Emacs?▼

You can reload edited elisp and run ERT tests without restarting Emacs by using emacsclient interactions. This workflow supports byte-compiling the updated code and verifying fixes immediately inside the active environment.

Do I need emacsclient to inspect and fix Emacs configuration issues?▼

Yes, you need emacsclient to inspect and fix Emacs configuration issues because the skill relies on emacsclient-based interactions to communicate with the running Emacs instance and execute the debugging workflow.

Why does my Emacs package debugging workflow require a preloaded helper file?▼

Your Emacs package debugging workflow requires a preloaded helper file at emacs/agent-skills-emacs.el to expose internal functions and variables. This file acts as a bridge to guide the interactive inspection steps within the live session.
