What it does

Code Import is an agent skill from nexu-io/open-design. Read an existing repository's structure into the project cwd as a normalised snapshot the agent can analyse without re-walking the tree on every turn.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `open-design.json`).

It sits in Development. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

Example prompts

“/code-import”

What it can do on your machine

Read from SKILL.md and the folder at commit 53231d4. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Import loads about 597 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~41
When it runs · the whole SKILL.md, loaded when a task matches: ~597

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

od.scenario: code-migration
od.mode: import

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

Source	Required	Notes
`repoPath`	yes	Absolute path to the repo's root, supplied via `od project import` or an upstream `od.context.assets[]` reference
`targetStack`	yes	{ framework, packageManager, styleSystem, componentLibrary } via the matching `form` GenUI surface

Output

text

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.

Anti-patterns the prompt fragment forbids

Walking node_modules / .git / .next / dist / build (record in code/index.json.skipped[] with reason).
Inferring a framework from a single file; require at least package.json's declared dep + a build-config presence (next.config.*, vite.config.*, etc.).
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.

Files

SKILL.md and 1 other file in plugins/_official/atoms/code-import of nexu-io/open-design.
