# tree

Runs a recursive radial-tree exploration engine across ideas, designs, or code. Useful when a problem demands exhaustive tree-of-thoughts branching until substantive convergence.

## What it does

The skill runs radial-tree exploration starting from a single grounded root. Each node expands through 12 framing passes and derives 12 evidence fields before scoring. The engine then recurses on leaves marked with `advances` verdicts. Incomplete `TODO` or `defer` leaves are forbidden.

Execution requires the `--preset` flag pointing to a built-in profile like `brainstorm`, `attack`, `design`, `code-audit`, or a custom markdown file. Caps on width, depth, and rounds default to infinity. Without explicit limits, the run continues until substantive convergence.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add skymanbp/cc-tree --skill tree -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tree/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tree/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add skymanbp/cc-tree --skill tree -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tree/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add skymanbp/cc-tree --skill tree -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tree/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install skymanbp/cc-tree tree
```

2. **Manually: put the files in place**
- File: `.github/skills/tree/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add skymanbp/cc-tree --skill tree -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/skymanbp/cc-tree --path skills/tree
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tree/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add skymanbp/cc-tree --skill tree -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/skymanbp/cc-tree/tree/HEAD/skills/tree/SKILL.md

## When to use it
- explore complex design choices through structured hypothesis trees
- run an automated code audit across files and directories
- dissect critique arguments on papers and design documents
- generate and score brainstormed concepts against evidence fields

## Example prompts
- /cc-tree:tree "dark-matter substructure detection" --preset brainstorm --depth 3
- /cc-tree:tree ./src --preset code-audit --max-branches 12 --out audit-out/
- /cc-tree:tree paper.md --preset attack --no-online

description: Universal radial-tree exploration engine — loads a preset, grounds a root, expands every node through 12 framing passes, derives each child in 12 evidence-bearing fields, scores it, and recurses on `advances` leaves until substantive convergence (or a user cap). Caps default to ∞; `defer / TODO / NEEDS-MORE-INFO` leaves are hard-banned. Use when the user wants the engine itself — a custom preset via `--preset <path>`, explicit control of a run, or "tree of thoughts" / 穷尽的树状探索 in general; for the four shipped use-cases prefer `/cc-tree:brainstorm`, `/cc-tree:attack`, `/cc-tree:design`, `/cc-tree:code-audit`, whose descriptions carry the per-use-case triggers.

# tree — universal radial-tree exploration engine

> **What this skill is.** A single engine implementing recursive
> radial-tree exploration (root → 12-framing expansion → per-node
> 12-field derivation → score → recurse on high-verdict leaves →
> terminate on **substantive convergence**). What varies between
> use-cases (brainstorm vs critique vs design vs code-audit) is the
> baseline recipe, node schema, scoring dimensions, and verdict
> vocabulary — all parameterized via a **preset** file.

> **What this skill is NOT.** Not a one-shot LLM call that returns a
> bulleted list. Not a chat interface — once the §2.0 glossary grill
> has settled terminology and the root is written, the engine runs to
> convergence without further prompts (§F6).
> Not bundled with a model — pure prompt-engineering on top of Claude
> Code's existing model setting.

The full engine specification lives in [`docs/ENGINE.md`](../../docs/ENGINE.md).
This SKILL.md is a 7-step navigation guide; **Read `docs/ENGINE.md`
before producing the first node** (the engine spec is what defines
"valid" for everything you'll write).

## 1. Invocation

```
/cc-tree:tree <root> --preset <name|path> [flags]
```

**`<root>`** is preset-typed:
- `brainstorm` preset → topic string, e.g. `"ways to detect dark-matter substructure"`
- `attack` preset → file path (`.md` / `.tex` / etc.) or quoted argument-text
- `design` preset → design-prompt string or `.md` file path
- `code-audit` preset → file path or directory path

**`--preset`** is required:
- Built-in: `brainstorm`, `attack`, `design`, `code-audit` (resolve to
  `presets/<name>.md` in this plugin)
- Path: `./my-custom.md` (any .md file with the right frontmatter)

### Common flags (apply across presets)

| Flag | Default | Meaning |
