Install the code-import skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/nexu-io/open-design.git /tmp/open-design
mkdir -p ~/.claude/skills
cp -r /tmp/open-design/plugins/_official/atoms/code-import ~/.claude/skills/code-import
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Code import

Spec §10 / §21.3.2: a code-migration / tune-collab run starts from a real repo (cloned via od project import or a path the user provided). This atom turns the raw checkout into a normalised on-disk record that subsequent atoms (design-extract, rewrite-plan, patch-edit) operate against. The point is to stop re-walking the tree on every turn — the agent reads code/index.json once and trusts the snapshot until the next explicit re-import.

Inputs

Output

project-cwd/
└── code/
    ├── index.json         # { files: { path, size, language, imports[] }[], packageJson?, lockfileKind, framework, styleSystem }
    ├── components.json    # detected components with file path + props snapshot
    ├── routes.json        # detected routing model (next/app, react-router, vite-router, …)
    └── meta.json          # { repoPath, gitSha, walkedAt, atomDigest, walkBudgetMs }

code/index.json is the input every other Phase 7 atom reads. The walk respects the runner's budgetMs option (default 60s) so large monorepos don't burn an entire run on import.

Convergence

The atom completes when code/index.json exists and contains at least one entry. Empty repos abort with a clear error event so the user re-imports.

  • Walking node_modules / .git / .next / dist / build (record in

package.json's declared dep + a build-config presence (next.config., vite.config., etc.).

  • Inferring a framework from a single file; require at least
  • Treating commented-out imports as live edges.

Status

Implemented by the daemon runner in apps/daemon/src/plugins/atoms/code-import.ts. The walker enforces its exclusions and time budget, detects framework evidence, and writes code/index.json.
