Update Workflows

Workflow 1: New Packages Added

When packages are added to Brewfile:

1. Check what was added: Review git diff or Brewfile
2. Update CLAUDE.md: Add to "Key Tools Included" section
3. Update README.md: Add to "Features" if notable
4. Group by category: Development, Cloud, Databases, Utilities, etc.
5. Keep alphabetical: Within each category

Example:

### Development Tools
- git, gh - Version control
- ripgrep, fd - Fast search tools (NEW)
- jq - JSON processor

Workflow 2: New Aliases Created

When aliases are added to .aliases:

1. Identify new aliases: Check .aliases file
2. Update CLAUDE.md: Add to "Git Aliases" or create new section
3. Update README.md: Add to usage examples if commonly used
4. Include examples: Show what the alias does

Example:

### Git Aliases
- `g` → `git`
- `gs` → `git status`
- `gp` → `git push` (NEW)

Workflow 3: Configuration Changes

When .zshrc, .aliases, or other configs change:

1. Review changes: Understand what was modified
2. Assess impact: Does this affect documented behaviour?
3. Update relevant sections: Modify docs to match new behaviour
4. Update examples: Ensure command examples still work
5. Note breaking changes: Highlight if setup process changes

Workflow 4: New Scripts or Features

When new scripts or automation is added:

1. Document purpose: What does it do?
2. Document usage: How to use it
3. Document requirements: Any dependencies or prerequisites
4. Add to CLAUDE.md: Technical details and implementation
5. Add to README.md: User-friendly usage guide

Verification Checklist

Before finalising documentation updates:

Content Accuracy:
□ All file paths exist and are correct
□ All command examples tested and work
□ Package lists match Brewfile
□ Alias examples match .aliases
□ Script descriptions match actual behaviour

Consistency:
□ British English throughout
□ Consistent formatting and style
□ Same terminology for same concepts
□ Code blocks have proper syntax highlighting
□ Section headers follow same pattern

Completeness:
□ All major features documented
□ No outdated information
□ Installation steps are current
□ Common tasks covered
□ Troubleshooting section relevant

Synchronisation:
□ CLAUDE.md and README.md align
□ No contradictions between docs
□ Both reflect current configuration
□ Cross-references are valid

Best Practices

Writing Style

• British English: "optimise" not "optimize", "colour" not "color"
• Clear and concise: Avoid unnecessary verbosity
• Active voice: "Run the command" not "The command should be run"
• Present tense: "The script installs" not "The script will install"
• Code examples: Include for all commands and usage

Markdown Formatting

# H1 for title
## H2 for main sections
### H3 for subsections

**Bold** for emphasis
`code` for commands, files, code
- Bullet lists for items
1. Numbered lists for steps

```bash
# Code blocks with syntax highlighting
command --option value

### Command Documentation

Always include:
1. **What it does**: Brief description
2. **When to use**: Context for usage
3. **Example**: Actual command with output
4. **Options**: Important flags or parameters

**Example**:
```markdown
### Update Brewfile

Updates the Brewfile with currently installed packages.

**When to use**: After installing new packages with `brew install`

```bash
brew bundle dump --force

This overwrites the existing Brewfile with all currently installed packages.

## Common Documentation Tasks

### Task 1: Document New Brewfile Packages

**Steps**:
1. Read Brewfile to see what was added
2. Group packages by type (Development, Cloud, Databases, etc.)
3. Update CLAUDE.md "Key Tools Included" section
4. Add brief description for each: `ripgrep - Fast grep alternative`
5. Keep alphabetical within categories

### Task 2: Update Command Examples

**Steps**:
1. Identify which commands changed
2. Test new commands to verify they work
3. Update both CLAUDE.md and README.md
4. Ensure syntax highlighting is correct
5. Add comments explaining the command

### Task 3: Add New Section

**Steps**:
1. Determine appropriate location (CLAUDE.md vs README.md vs both)
2. Use consistent heading level
3. Write clear, concise content
4. Include examples
5. Update table of contents if present

### Task 4: Sync Between Docs

**Steps**:
1. Read both CLAUDE.md and README.md
2. Identify inconsistencies or contradictions
3. Determine correct information (check actual files)
4. Update both docs to align
5. Ensure cross-references are valid

## Example Workflows

### Example 1: Updating for New Packages

**User**: "I added ripgrep and fd to Brewfile, update the docs"

**Steps**:
1. **Verify addition**: Check Brewfile shows `brew "ripgrep"` and `brew "fd"`
2. **Update CLAUDE.md**:
   ```markdown
   ### Key Tools Included
   - Development: git, gh, nvm, pnpm, yarn, bun
   - Utilities: jq, ripgrep, fd, httpie, direnv (UPDATED)

3. Update README.md:

   ### Features
   - Fast file and content searching with ripgrep and fd
   

4. Confirm: "Updated both CLAUDE.md and README.md to document ripgrep and fd"

Example 2: New Alias Documentation

User: "Document the new gp alias"

Steps:

1. Check alias: Read .aliases to find alias gp='git push'
2. Update CLAUDE.md:

   ### Git Aliases
   - `g` → `git`
   - `gs` → `git status`
   - `gp` → `git push`
   

3. Update README.md (usage example):

   # Push changes
   gp
   

4. Confirm: "Added gp alias to documentation in both files"

Example 3: Verifying Accuracy

User: "Check if the documentation is accurate"

Steps:

1. Read CLAUDE.md and README.md
2. Compare with actual files:
   • Check Brewfile matches documented packages
   • Verify aliases exist in .aliases
   • Test command examples work
3. Identify discrepancies:
   • Found: README mentions "nvm" but Brewfile uses "fnm"
   • Found: Outdated path in CLAUDE.md
4. Update:
   • Fix README: Change "nvm" to "fnm"
   • Fix CLAUDE.md: Update path
5. Report: "Fixed 2 inaccuracies in documentation"

Important Notes

• Accuracy is paramount: Documentation must match reality
• Test examples: All command examples should work
• Keep current: Update docs whenever configurations change
• British English: Consistent spelling throughout
• Be thorough: Check both files for updates
• Version control: Document changes in git commits
• User perspective: README should be approachable for newcomers

Maintenance Schedule

Recommend updating documentation:

• After major changes: New features, significant refactoring
• Before commits: Ensure docs reflect committed changes
• Monthly review: Check for drift from actual configuration
• On request: When user asks to update or verify docs

Documentation Quality Criteria

Good documentation should be:

1. Accurate: Matches actual implementation
2. Current: Reflects latest changes
3. Complete: Covers all major features
4. Consistent: Same style and terminology
5. Clear: Easy to understand
6. Tested: All examples work
7. Well-organised: Logical structure
8. Properly formatted: Valid markdown, syntax highlighting
