Curated by Skill Harbor: a systematic method for analyzing an unfamiliar codebase and producing a structured onboarding guide, built for developers joining a new project or setting up an AI coding agent in an existing repo for the first time. It works in phases: first a fast reconnaissance that gathers signals without reading every file (package manifests, framework fingerprints, entry points, directory snapshot, config and tooling detection, test layout), then an architecture mapping step that identifies the tech stack, data flow, and key conventions, and finally the generation of a guide plus a starter CLAUDE.md so the next session starts with context instead of rediscovery. Designed around the questions a newcomer actually asks: where does execution start, where does state live, how do I run the tests, what are the unwritten rules. By @affaan-m, listed here with credit to its creator. From the affaan-m/ECC repository (MIT). Honest caveats: guidance and analysis, it produces documents rather than modifying your code; it needs access to the repo (a local checkout or enough of the tree pasted in) to do the reconnaissance phase properly. Skill Harbor never reviews the code, review it yourself before use.
Version:
Install
Copy the install package below, then paste it into MuseCommunity-built. Skill Harbor doesn't audit code — review the source before installing.
Use "Codebase Onboarding" with your Muse. Prerequisites: the Muse app (mobile or web), and access to the repository you want to understand (local checkout, or paste the directory tree and key config files). Produces documents, modifies nothing. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/codebase-onboarding/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Onboard me onto this codebase: [repo path, or paste the top-level tree plus package.json / README]." 3. Ask Muse to run the phases: reconnaissance first (manifests, frameworks, entry points, tooling), then the architecture map, then the onboarding guide and starter CLAUDE.md. Tip: the reconnaissance phase is deliberately shallow and fast. Do not let it drift into reading every file; the point is a map, not a full audit. Safety: a skill is plain-text instructions; it runs nothing by itself. Never paste secrets into a chat, and review anything Muse proposes before it acts.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
