Directory Structure Mapper (ds-mapper)

Scans any repository and produces an annotated ASCII directory tree plus a module table and suggested entry points.

Dev & CodingBeginner★ 817⑂ 85AI score 8/10Last updated: Sep 4, 2026

What it does

  • Scans the repo root with find/ls, then reads manifest files (package.json, Cargo.toml, pyproject.toml, go.mod) to detect language, framework and package manager.
  • Recursively maps main directories up to 3 levels deep and prints an ASCII tree with a one-line note for each folder.
  • Adds a module responsibility table (directory / role / key files) and "start reading here" suggestions for entry point, docs and config.
  • Skips noise directories (node_modules, .git, vendor, __pycache__) and splits monorepos into per-package sections.

Who it's for

  • Developers onboarding onto an unfamiliar codebase or inherited project.
  • Anyone exploring an open-source repo who wants to find the core modules fast.
  • Maintainers who need a "Project structure" section for README or onboarding docs.

Examples

  1. "How is this repo organized?" → stack summary + 3-level tree + module table.
  2. Freshly cloned Next.js app: "show me the directory tree" → roles of src/app, components, lib and the startup file.
  3. Monorepo: "break it down per package" → separate trees and responsibilities for each packages/*.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/ds-mapper folder from the GitHub repo laolaoshiren/claude-code-skills-zh into my ~/.claude/skills/ds-mapper/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/laolaoshiren/claude-code-skills-zh.git /tmp/ccs-zh && mkdir -p ~/.claude/skills && cp -r /tmp/ccs-zh/skills/ds-mapper ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/laolaoshiren/claude-code-skills-zh.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r claude-code-skills-zh/skills/ds-mapper ~/.claude/skills/
  5. Restart Claude Code and confirm ds-mapper appears in your skill list.
  6. From a project directory, ask "show me this project's structure" to trigger it (add "annotate in English" if you don't want Chinese comments).
