# software-engineer

A skill that gives the agent rules for code style, documentation and workflow: no filler comments, no git commits on its own, questions when something is unclear.

## What it does

The skill spells out how the agent should behave while editing code and working inside a repository. Comments are kept for non-obvious design decisions and workarounds; TODO and FIXME lines stay out of commits unless you ask for them. Clear naming and structure come before explanatory comments.

A workflow section tells the agent to check whether the project runs spec-first, TDD or something else. It looks for `docs/` and `specs/` directories, plan files and test-first patterns, then follows whatever it finds. Commands that change repo state, such as `git add`, `git commit` and `git push`, are off limits without a direct request, while `git status` and `git diff` are fair game for analysis. When context is missing, it searches the web or context7 and asks you instead of guessing.

Output formatting and code organization get their own rules: no emojis, respect for `NO_COLOR`, no hardcoded ANSI codes, attention to accessibility and performance. If requirements are vague, or the agent is about to add a type ignore or an `any`, it stops and asks. Two reference files ship with it: `references/workflow-patterns.md` and `references/implementation-workflow.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add siviter-xyz/dot-agent --skill software-engineer -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add siviter-xyz/dot-agent --skill software-engineer -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add siviter-xyz/dot-agent --skill software-engineer -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install siviter-xyz/dot-agent software-engineer
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add siviter-xyz/dot-agent --skill software-engineer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/siviter-xyz/dot-agent --path skills/software-engineer
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add siviter-xyz/dot-agent --skill software-engineer -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/siviter-xyz/dot-agent/tree/HEAD/skills/software-engineer/SKILL.md

## When to use it
- keep leftover TODO and temporary comments out of commits
- stop the agent from committing and pushing on its own
- pick up an existing spec-first or TDD process in the repo
- get a question instead of a made-up answer about an unfamiliar framework
- settle on one style for docs and terminal output

## Example prompts
- Refactor this module and leave git alone — I'll commit myself
- Check which workflow this project uses and follow it
- Before adding a type suppression, explain why it's needed

# Software Engineering Principles

Core principles and preferences for code style, documentation, and development workflow.

## Code Style and Patterns

- **Avoid unnecessary comments**: Code should be self-documenting. Reserve comments for non-obvious design decisions, workarounds, or complex logic. Avoid comments that restate what the code obviously does.

- **Clean codebase**: Avoid leaving TODO, FIXME, or temporary comments in committed code UNLESS directed. Either implement the feature, create an issue, or remove the comment. Ignore existing ones.

- **Self-documenting code**: Prefer clear naming and structure over explanatory comments. Method, class, and member documentation should use language/stack best practices. Don't add useless inline comments next to statements UNLESS they explain
confusing or complex behaviour.

## Documentation

- **Concise and useful**: Documentation should be informative but not verbose. READMEs should focus on essential information without unnecessary elaboration.

- **Structure over verbosity**: Prefer well-organized, scannable documentation with clear headings over long paragraphs. Use short examples to illustrate concepts.

## Development Workflow

- **Workflow detection**: Check if project uses spec-first, TDD, or other structured workflows. Look for:
  - `docs/` or `specs/` directories with specs
  - Test-first patterns in codebase
  - Plan files or structured documentation
  - Follow existing workflow patterns when present

- **No git modifications**: Do not use Git commands that modify the repository state (such as `git add`, `git commit`, `git push`) UNLESS directed. Focus on code edits directly. Status and diff commands (`git status`, `git diff`) are permitted and encouraged for analysis.

- **Fact-based approach**: Do not hallucinate or assume. If you don't know something or need additional context about a framework or technology, search the web or use context7 for up-to-date documentation. If clarification is needed, ask the user before making changes.
