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□ No outdated information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

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:

### Update Brewfile

Updates the Brewfile with currently installed packages.

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

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) ``

1. Update README.md:

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

1. 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:

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

1. Update README.md (usage example):

``markdown # Push changes gp ``

1. 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

1. Identify discrepancies:

- Found: README mentions "nvm" but Brewfile uses "fnm" - Found: Outdated path in CLAUDE.md

1. Update:

- Fix README: Change "nvm" to "fnm" - Fix CLAUDE.md: Update path

1. 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
