# Code Format Skill (Entry Map)
> **Goal:** Guide agent to the exact formatting procedure needed.
## Quick Start (Pick One)
- **Format .NET code (C#)** → `references/dotnet-format.md`
- **Format JSON/YAML/Markdown** → `references/prettier-format.md`
- **Format everything** → `references/fix-all.md`
## When to Use
- Fix code style violations (indentation, spacing, line endings)
- Apply .editorconfig rules consistently
- Prepare code for commit (pre-commit hook formatting)
- Enforce team coding standards
- Format specific files or entire codebase
**NOT for:** building (dotnet-build), testing (dotnet-test), or linting (code-analyze)
## Inputs & Outputs
**Inputs:** `target` (dotnet/prettier/all), `files` (specific files or directories), `verify` (check-only mode)
**Outputs:** Formatted files (modified in-place), exit code (0=success, non-zero=violations)
**Guardrails:** Non-destructive (can run with --verify-no-changes), respects .editorconfig, integrates with pre-commit
## Navigation
**1. Format .NET Code** → [`references/dotnet-format.md`](references/dotnet-format.md)
- Format C# files (.cs), apply dotnet format rules, fix code style issues
**2. Format with Prettier** → [`references/prettier-format.md`](references/prettier-format.md)
- Format JSON, YAML, Markdown, JavaScript, TypeScript files
**3. Format All Code** → [`references/fix-all.md`](references/fix-all.md)
- Run all formatters in sequence (dotnet + prettier), comprehensive formatting
## Common Patterns
### Quick Format (.NET)
```bash
cd ./dotnet
dotnet format PigeonPea.sln
```
### Quick Format (Prettier)
```bash
npx prettier --write "**/*.{json,yml,yaml,md}"
```
### Format Everything
```bash
./.agent/skills/code-format/scripts/format-all.sh
```
### Verify Only (Check Mode)
```bash
cd ./dotnet
dotnet format PigeonPea.sln --verify-no-changes
```
### Format Specific Files
```bash
# .NET
dotnet format --include ./console-app/Program.cs
# Prettier
npx prettier --write ./README.md
```
## Troubleshooting
**Format fails:** Check error messages. See specific reference files for detailed error handling.
**Files not formatted:** Check .editorconfig rules, file extensions, ignore patterns.
**Pre-commit hook fails:** Run formatters manually first, then commit. See `references/fix-all.md`.
**Conflicting styles:** .editorconfig takes precedence. Check configuration files.
**Performance issues:** Format specific projects/files instead of entire solution.
## Success Indicators
### dotnet format
```
Format complete in X ms.
```
No files changed (if already formatted), or list of formatted files.
### prettier
```
✔ Formatted X files
```
Or no output if all files already formatted.
## Integration
**Before commit:** Use pre-commit hooks to auto-format (configured in `.pre-commit-config.yaml`)
**Manual formatting:** Run before pushing code, before PR creation
**CI/CD:** Verify formatting in CI (use --verify-no-changes / --check mode)
**With other skills:**
- Before: code-analyze (fix style first)
- After: dotnet-build (build clean code)
## Configuration Files
- **`.editorconfig`**: Defines formatting rules (indent size, line endings, etc.)
- **`.prettierrc.json`**: Prettier configuration (print width, quotes, etc.)
- **`.pre-commit-config.yaml`**: Pre-commit hook configuration
- **`.prettierignore`**: Files to exclude from prettier formatting
