## What it does

The skill runs via `/best-practices` to convert incomplete instructions into structured prompts. It offers two modes. You can transform directly or inspect the repository first. Direct mode applies rules right away, while context mode explores the codebase.

For context building, the skill runs three parallel agents via the `Task` tool: `task-intent-analyzer`, `best-practices-referencer`, and `codebase-context-builder`. These subagents inspect repository paths, extract relevant patterns, and check `CLAUDE.md`. The final prompt receives automated verification steps, strict dependency constraints, and phase breakdown.

Context mode relies on the `Task` tool and agent files in `agents/`. Make sure your setup supports subagent tasks.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill best-practices -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill best-practices -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill best-practices -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MoizIbnYousaf/ai-agent-skills best-practices
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill best-practices -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MoizIbnYousaf/ai-agent-skills --path skills/best-practices
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill best-practices -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/MoizIbnYousaf/ai-agent-skills/tree/HEAD/skills/best-practices/SKILL.md

## When to use it
- add automated tests and verification steps to coding prompts
- ground instructions in specific file paths and CLAUDE.md rules
- enforce constraints against new dependencies and out-of-scope edits
- split complex tasks into exploration, planning, and implementation phases

## Example prompts
- /best-practices implement email validation
- /best-practices fix 500 error in order checkout endpoint

# Best Practices — Prompt Transformer

> Transform prompts by adding what Claude needs to succeed.

## Start Here

Based on user's request:

**User provides a prompt to transform:**
→ Ask using AskUserQuestion:
  - **Question:** "How should I improve this prompt?"
  - **Header:** "Mode"
  - **Options:**
    1. **Transform directly** — "I'll apply best practices and output an improved version"
    2. **Build context first** — "I'll gather codebase context and intent analysis first"

**User asks to learn/understand:**
→ Show the 5 Transformation Principles section

**User asks for examples:**
→ Link to references/before-after-examples.md

**User asks to evaluate a prompt:**
→ Use the Success Criteria eval rubric at the end of this document

---

## If "Transform directly"

Apply the 5 principles below and output the improved prompt immediately.

## If "Build context first"

Launch 3 parallel agents to gather context:

```
Run these agents IN PARALLEL using the Task tool:

- Task task-intent-analyzer("[user's prompt]")
- Task best-practices-referencer("[user's prompt]")
- Task codebase-context-builder("[user's prompt]")
```

### What Each Agent Returns

| Agent | Mission | Returns |
|-------|---------|---------|
| **task-intent-analyzer** | Understand what user is trying to do | Task type, gaps, edge cases, transformation guidance |
| **best-practices-referencer** | Find relevant patterns from references/ | Matching examples, anti-patterns to avoid, transformation rules |
| **codebase-context-builder** | Explore THIS codebase | Specific file paths, similar implementations, conventions |

### After Agents Return

1. **Synthesize findings** — Combine intent + best practices + codebase context
2. **Apply matching patterns** — Use examples from best-practices-referencer as templates
3. **Ground in codebase** — Add specific file paths from codebase-context-builder
4. **Transform the prompt** — Apply the 5 principles with all gathered context
5. **Output** — Show improved prompt with before/after comparison

### Agent Definitions

The agents are defined in `agents/`:
- `agents/task-intent-analyzer.md` — Analyzes intent, gaps, and edge cases
- `agents/best-practices-referencer.md` — Finds relevant examples and patterns from references/
- `agents/codebase-context-builder.md` — Explores codebase for files and conventions

---

## Transformation Workflow

When transforming (after mode selection):

1. **Identify what's missing** — Check against the 5 principles below
2. **Add missing elements** — Verification, context, constraints, phases, rich content
3. **Output the improved prompt** — In a code block, ready to copy-paste
4. **Show what changed** — Brief comparison of before/after
