A checklist skill for everyday coding: it makes the agent read a file before editing, keep changes minimal and check for security holes.

## What it does

The skill kicks in whenever the agent writes or modifies source code — new features, added code, edits to existing files. It triggers on requests like "write a…", "implement…", "add…", "modify…" and on any task that touches the Edit or Write tools.

Inside are three groups of items. Before starting: read the target file with Read and confirm you understand the existing logic. While coding: keep changes minimal, no over-engineering; add type hints in Python and avoid `any` in TypeScript; check for command injection, XSS and SQL injection. After finishing: make sure the code runs without syntax errors, strip `print`/`console.log` debug lines and temp files, then give a short summary of what changed.

The reference section shows common mistakes — a mutable default argument, a bare `except` — and security checkpoints: validate user input, use `pathlib` for file paths, never hardcode API keys or passwords. Skip it for pure reading tasks, config-only changes and work already handled by `bug-detective`, `architecture-design` or `verification-loop`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill daily-coding -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill daily-coding -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill daily-coding -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Galaxy-Dawn/claude-scholar daily-coding
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill daily-coding -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Galaxy-Dawn/claude-scholar --path skills/daily-coding
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill daily-coding -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/Galaxy-Dawn/claude-scholar/tree/HEAD/skills/daily-coding/SKILL.md

## When to use it
- read a file before editing instead of changing it blind
- keep an edit inside its minimal scope without over-engineering
- add type hints in Python and drop `any` in TypeScript
- check code for command injection, XSS and SQL injection
- strip debug output and temp files once the work is done

## Example prompts
- implement an endpoint for avatar uploads
- modify `process` — it breaks on an empty list
- add type hints to `parser.py`

# Daily Coding Checklist

A minimal coding quality assurance checklist ensuring every code modification follows best practices.

## When to Use

Use this skill for:
- Implementing new features
- Adding code or modifying existing code
- User requests like "write a...", "implement...", "add...", or "modify..."
- Any coding task that involves Edit or Write tools

## When Not to Use

Do not use this skill for:
- Pure reading or understanding tasks with no modification intent
- Work already covered by specialized skills such as `bug-detective`, `architecture-design`, or `verification-loop`
- Configuration-only changes
- Documentation-only writing

## Core Checklist

### Before Starting

- [ ] **Read before modify** - Must read target file with Read tool before making changes
- [ ] **Understand context** - Confirm understanding of existing code logic and design intent

### During Coding

- [ ] **Minimal changes** - Only change what's necessary, no over-engineering, no unrelated features
- [ ] **Type safety** - Add type hints for Python, avoid `any` in TypeScript
- [ ] **Security check** - Avoid command injection, XSS, SQL injection vulnerabilities

### After Completion

- [ ] **Verify execution** - Ensure code runs correctly with no syntax errors
- [ ] **Clean up** - Remove print/console.log debug statements and temporary files
- [ ] **Brief summary** - Inform user what was changed and the scope of impact

## Quick Reference

### Common Mistakes to Avoid

```python
# ❌ Don't
def process(data=[]):  # Mutable default argument
    pass

# ✅ Should
def process(data: list | None = None):
    data = data or []
```

```python
# ❌ Don't
except:  # Bare except
    pass

# ✅ Should
except ValueError as e:
    logger.error(f"Processing failed: {e}")
    raise
```

### Security Check Points

- User input must be validated/escaped
- Use pathlib for file paths, avoid path traversal
- Never hardcode sensitive info (API keys, passwords)
