New engineer repo walkthrough
A new hire gets an agent-guided tour of an unfamiliar codebase.
Overview
On their first day, a new engineer can ask an agent to walk them through the repo structure, key modules, and where to make a first small change, instead of scheduling a senior engineer's time.
How this workflow works
- Problem it solves
- Onboarding a new engineer eats a senior engineer's time re-explaining the same codebase structure.
- Expected outcome
- A new hire can self-serve a guided walkthrough of the codebase in their first hour.
- Setup time
- 10 minutes
Steps
- 01New hire asks for a tourThey open the coding agent in the repo and ask for an overview.
- 02Agent explains structureThe agent summarizes the module layout, key entry points, and conventions.
- 03Suggest a first taskThe agent points to a small, well-scoped starter issue.
Prerequisites
- Coding agent with repo access
- A backlog of labeled good-first-issues

Useful but needs guardrails
Works well for the narrow case we use it for. We had to add explicit boundaries after it did something a bit too enthusiastic in week one.
- Capable when scoped well
- Needs explicit boundaries
- Support response was slow
Genuinely changed how our team ships
We put this in front of real work for three weeks before trusting it near main. It's now part of the default flow, and reviewers spend their time on the parts that actually need judgment.
- Fast to set up
- Caught real bugs
- Occasional context loss on very large diffs
Solid, with a learning curve
Took about a week to tune the config to our repo's conventions, but once it clicked it's been reliable. Wouldn't hand it the riskiest changes unsupervised yet.
- Good defaults
- Responsive to feedback
- Setup docs assume more context than we had
Exactly what we needed
Replaced a manual process that was eating an hour a day across the team. Straightforward to configure and it's held up under real usage.
- Saves real time weekly
