## What it does

This skill writes `.md` rule definitions for the `slop-grader` text evaluator. It shapes isolated checks into either `# Line Rules` using boolean true or false criteria or `# Document Rules` using score tiers. Each check gets an explicit snake_case identifier so evaluation outputs stay readable.

Once drafted, the assistant validates the file with `npx @lukstei/slop-grader@latest --check -r <rule-file>`. It corrects formatting flaws until the validator passes without errors.

The agent will not run document grading itself. Its instructions restrict it to rule generation and syntax validation, leaving document execution to the user. Running the validator requires Node.js with `npx` installed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add lukstei/slop-grader --skill create-slop-grader-rules -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add lukstei/slop-grader --skill create-slop-grader-rules -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add lukstei/slop-grader --skill create-slop-grader-rules -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install lukstei/slop-grader create-slop-grader-rules
```

2. **Manually: put the files in place**
- File: `.github/skills/create-slop-grader-rules/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add lukstei/slop-grader --skill create-slop-grader-rules -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/lukstei/slop-grader --path skills/create-slop-grader-rules
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add lukstei/slop-grader --skill create-slop-grader-rules -a opencode
```

### Claude.ai

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

## When to use it
- write granular Markdown rule files for slop-grader
- configure line-level checks with boolean pass and fail criteria
- set up document-level multi-tier scoring rules
- test rule syntax automatically via `slop-grader --check`

## Example prompts
- Build a slop-grader rule that detects condescending words like simply or obviously
- Create a document-level ruleset for tutorial structure in Markdown
- Write atomic slop-grader checks for documentation guidelines and validate them

# Create slop-grader rules

Help the user create custom rule files (`.md`) for [`slop-grader`](https://github.com/lukstei/slop-grader/blob/main/README.md).

For complete syntax rules and validation constraints, refer to [docs/SYNTAX.md](https://github.com/lukstei/slop-grader/blob/main/docs/SYNTAX.md).

## Example Ruleset

```markdown
Custom documentation standards.

# Document Rules

## task_orientation
Is the guide organized around user tasks rather than internal system architecture?

### Criteria
- Architecture dump with no clear user workflow
- Mixed explanations requiring the reader to assemble the workflow
- Task-oriented with clear sequential steps
- Cookbook-grade with inputs, steps, and expected outputs

# Line Rules

## minimizing_language
Does the line use condescending shortcuts ("simply", "just", "obviously") to minimize a complex step?

### Criteria
- **true**: The line minimizes a step requiring configuration or technical decisions.
- **false**: The step is genuinely trivial (e.g. "click Save"), or no minimizing term appears.
```

## Core Principle: Keep Rules Granular

Design rules with single, atomic responsibilities. Avoid bundling multiple distinct checks into one composite rule (e.g. never combine typos, compound spacing, and grammar into a catch-all rule):

- **Debuggability:** When `slop-grader` flags a violation, the report displays the rule ID. Granular IDs (e.g. `compound_spacing`, `comma_placement`) pinpoint the exact issue instead of requiring manual deduction.
- **Evaluator accuracy:** Evaluators score focused, binary criteria far more reliably than composite prompts that test multiple disparate error types simultaneously.
- **Independent tuning:** Isolating rules lets you refine criteria and edge-case examples for one pattern without causing regressions in others.
- **Actionable fixes:** Downstream fix workflows (like the `slop-grading` skill) can propose exact replacements when the rule name is specific.

## Workflow

1. **Clarify requirements:** Ask what patterns, guidelines, or quality criteria the user wants to enforce. Determine the appropriate scopes:
   - `# Line Rules`: Evaluates line by line. Always boolean `noul` questions requiring `- **true**:` and `- **false**:` criteria.
   - `# Document Rules`: Evaluates the whole document. Multi-tier `score` questions (bullet list of at least 2 levels) or document-level boolean `noul` questions.
2. **Draft the ruleset:** Write the `.md` rule file adhering to [docs/SYNTAX.md](https://github.com/lukstei/slop-grader/blob/main/docs/SYNTAX.md).
   - Keep rules atomic (one pattern per rule ID). Split broad checks into separate rules.
