Code Function

Turn any project into one self-contained interactive HTML map that answers: which code implements this feature/page? Show every feature of the project, and for each, all the code across frontend/backend/database/workers with exact file:line — clickable to open in the user's editor. Use when the user says 'code-function', '功能地图', '这个功能对应哪段代码', '生成功能地图', 'locate the code for <feature>', or asks to map features/pages to their implementation. Also use to refresh a map generated earlier.

From the SKILL.md

# code-function

Turn any project into **one self-contained, offline HTML file** that answers the recurring
question: *"I see a feature — where is the code that implements it?"*

The front page (**功能 / Features**) lists every feature of the project as a card. Each card
shows the files and line ranges that implement that feature across the whole stack — frontend,
backend, database, workers, tests — each tagged by layer, and **clickable to open in the user's
editor at the exact line**.

Everything here is original work (see `LICENSE`); no third-party code is vendored.

## What the generated HTML contains

- **功能 / Features** *(default)* — feature → cross-stack code cards. Cards are **collapsed by
  default and expand on click** (search auto-expands matches; 展开全部/折叠全部 buttons toggle all).
  Each code line is clickable to open in the editor.
- **架构 / Architecture** — module dependency graph layered by dependency depth; hover to trace
  imports/imported-by, click for a module panel.
- **文件 / Explorer** — squarified lines-of-code treemap; drill into directories via breadcrumbs.
- **Facet tabs** *(optional)* — stack-specific pages (API surface, DB schema, routes, jobs…)
  declared in `facets.json`.
