New Engineer Onboarding Kit — Understand Any Repo, Test It & Fix the README
Everything you need for the moment you inherit or join an unfamiliar codebase. Map the architecture, key modules, and core flows to build a mental model fast; generate a real test suite so you can safely make your first changes; and run a professional editor's review of the README and docs so the next person ramps up faster. For engineers taking over, joining, or onboarding onto a project they didn't write.
You save $8 vs buying individually.
What's included (3 skills)
Point it at an unfamiliar or inherited repo and quickly understand it. Maps the architecture, identifies the key modules and entry points, traces the core end-to-end flows, surfaces the conventions and gotchas, and assembles a clean ONBOARDING.md — turning a strange codebase into a clear mental model fast. Built for the moment you join a project, take one over, or have to explain a repo before changing it.
Generate a real test suite for any function, module, or file — meaningful edge cases, error paths, boundary conditions, and proper mocks, not happy-path stubs. Detects your project's framework and conventions, plans the cases deliberately before writing, and hands back runnable tests plus a summary of what's covered. Built to write the tests that actually catch bugs.
A professional technical editor's review for your docs. Catches missing context, unclear writing, and unverifiable claims in READMEs, API docs, and changelogs before they ship — with a PASS/REVISE verdict and a prioritized fix list.
