# Code Tour Skill

Walk someone through the code instead of explaining it twice

## What this does

Explaining a codebase over someone's shoulder does not scale, and a written doc drifts away from the code. This creates step-by-step tours that point at real files and real line numbers, so a reader clicks through the code itself. Reach for it when somebody new is ramping up, when a pull request needs a guided read, or when you are tired of explaining the same part twice.

### Top 3 things it does for you

- Build an onboarding walkthrough for a new joiner
- Make a guided tour of this pull request
- Explain how one part of the system works, step by step

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Code Tour Skill

This creates CodeTour .tour files: step-by-step walkthroughs that link to real files and line numbers, so a reader moves through the actual code rather than a description of it. Tours are persona-targeted, meaning the same codebase can be explained differently depending on who is reading.

It supports a range of developer personas, among them a new joiner, a bug fixer, an architect, a PR reviewer and a security reviewer, and it covers all the CodeTour step types including file and line, selection, pattern, uri, commands and view. Tour-level fields such as ref, isPrimary and nextTour are handled too, so tours can be chained.

Common reasons to reach for it: onboarding, a tour for a pull request or a bug, a root cause analysis walkthrough, an architecture overview, a contributor guide, or any request for a structured walk through code. It works with any repository in any language.

## Questions

### Is Code Tour Skill safe to install?

AIR scanned this exact version of Code Tour Skill and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 90921cc46f4e, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/code-tour.

### How do I install Code Tour Skill?

Open https://airmarket.ai/app/code-tour on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/github/awesome-copilot/tree/90921cc46f4e452ea379e70884d60ec25263f16a/skills/code-tour. Install from that link, not the branch.
