## What it does

The skill generates or modifies a `konsistent.json` configuration file by inspecting existing TypeScript repository layouts. The `konsistent` CLI is not a style linter; it audits filesystem layout, missing companion files via predicates like `haveFiles`, and import/export conventions across modules.

When analyzing code, the skill compiles an evidence table across cohorts such as packages or routes. By default, a candidate pattern becomes an active rule only if it appears at least three times and accounts for at least two-thirds of the cohort. The skill intentionally avoids tailoring configs to produce zero violations. Existing anomalies remain flagged as intentional audit findings.

Before editing rules, the repository must have the `konsistent` package installed in `devDependencies` along with a run script in `package.json`. The skill inspects `node_modules/konsistent/konsistent.schema.json` directly to validate its output.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add vercel-labs/konsistent --skill konsistent-config -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add vercel-labs/konsistent --skill konsistent-config -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add vercel-labs/konsistent --skill konsistent-config -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install vercel-labs/konsistent konsistent-config
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add vercel-labs/konsistent --skill konsistent-config -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/vercel-labs/konsistent --path skills/konsistent-config
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add vercel-labs/konsistent --skill konsistent-config -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/vercel-labs/konsistent/tree/HEAD/skills/konsistent-config/SKILL.md

## When to use it
- enforce structural directory conventions in a TypeScript codebase
- detect file naming inconsistencies against dominant repository patterns
- require companion files across packages using the haveFiles predicate
- configure acronym casing overrides in kebabToPascalMap

## Example prompts
- Create a konsistent.json configuration based on existing repository patterns
- Add a convention to konsistent.json requiring src/index.ts in all packages
- Configure case map overrides for acronyms in konsistent.json

# konsistent Configuration

Create or modify a `konsistent.json` file that enforces structural conventions for the project. The `konsistent` CLI checks filesystem structure and TypeScript exports/imports — it is not a style linter.

## Core Objective

**Important reminder:** DO NOT write a `konsistent.json` file that leads to zero errors when running the `konsistent` check. That would defeat the purpose. The objective is to create a `konsistent.json` file that identifies violations to patterns used in the codebase, even if they are not being 100% adhered to. Add conventions based on dominant patterns in the codebase, even if other instances violate those patterns.

Treat the existing codebase as evidence from which to infer conventions, not as a specification that every convention must accept. Existing files that do not follow a dominant pattern are expected findings, not proof that the convention is wrong.

A successful configuration can make `konsistent` exit with violations. The violations are the intended audit output. Only `konsistent validate` is expected to pass without errors.

## Workflow

### 1. Setting Up The `konsistent` CLI (only if not set up yet)

Check if the `konsistent` package is already installed:

- `konsistent` available in root `package.json`
- `node_modules/konsistent` directory exists
- a `konsistent` script exists in `package.json`

If not, the `konsistent` CLI must be installed first. Use the project's package manager. For example, with PNPM:

```bash
pnpm add konsistent --save-dev
```

Then, ensure `package.json` has a `konsistent` script which invokes the `konsistent` CLI. At a minimum:

```
  "scripts": {
    "konsistent": "konsistent"
  }
```

If or once all of these are ready, proceed to section 2.

### 2. Determining Operation Mode Based on Presence Of `konsistent.json` File

1. Check if `konsistent.json` already exists at the project root.
