## What it does

The command first reads the current state: it lists markdown files, counts status markers across `docs/` and `specs/`, and pulls the last week of commits touching `*.md`. Then it compares what the docs claim against what the last phase actually shipped and fixes the gaps.

Four targets get rewritten: the phase document, `specs/implementation_status.md`, the implementation specs, and the root `CLAUDE.md` and `README.md`. Finished items get a ✅, percentages are recalculated, and complex components pick up notes on how they were built. It will not create new spec files — only edit what already sits in `specs/`. Worth knowing before you run it on a repo with no specs directory.

An argument picks the mode: `--implementation`, `--api`, `--architecture`, `--sync` or `--validate`. Tool access is limited to `Read`, `Write`, `Edit` and `Bash`, so edits land directly in your files. It closes with a summary of updated files, new percentages and the practices it recorded.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command documentation/update-docs
```

2. **Manually: put the files in place**
- File: `.claude/commands/update-docs.md` — Call it with /update-docs. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/update-docs.md` — Call it with /prompts:update-docs. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/update-docs.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/update-docs.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/documentation/update-docs.md

## When to use it
- mark finished phase tasks and recalculate completion percentages
- reconcile a spec with what actually got coded
- add new best practices and known limitations to `CLAUDE.md`
- refresh the API section after interface changes
- bring `testing_plan.md` in line with recent test runs

## Example prompts
- /update-docs --implementation
- /update-docs --api
- /update-docs --sync

# Documentation Update & Synchronization

Update project documentation systematically: $ARGUMENTS

## Current Documentation State

- Documentation structure: !`find . -name "*.md" | head -10`
- Specs directory: @specs/ (if exists)
- Implementation status: !`grep -r "✅\|❌\|⚠️" docs/ specs/ 2>/dev/null | wc -l` status indicators
- Recent changes: !`git log --oneline --since="1 week ago" -- "*.md" | head -5`
- Project progress: @CLAUDE.md or @README.md (if exists)

## Task

## Documentation Analysis

1. Review current documentation status:
   - Check `specs/implementation_status.md` for overall project status
   - Review implemented phase document (`specs/phase{N}_implementation_plan.md`)
   - Review `specs/flutter_structurizr_implementation_spec.md` and `specs/flutter_structurizr_implementation_spec_updated.md`
   - Review `specs/testing_plan.md` to ensure it is current given recent test passes, failures, and changes
   - Examine `CLAUDE.md` and `README.md` for project-wide documentation
   - Check for and document any new lessons learned or best practices in CLAUDE.md

2. Analyze implementation and testing results:
   - Review what was implemented in the last phase
   - Review testing results and coverage
   - Identify new best practices discovered during implementation
   - Note any implementation challenges and solutions
   - Cross-reference updated documentation with recent implementation and test results to ensure accuracy

## Documentation Updates

1. Update phase implementation document:
   - Mark completed tasks with ✅ status
   - Update implementation percentages
   - Add detailed notes on implementation approach
   - Document any deviations from original plan with justification
   - Add new sections if needed (lessons learned, best practices)
   - Document specific implementation details for complex components
   - Include a summary of any new troubleshooting tips or workflow improvements discovered during the phase

2. Update implementation status document:
   - Update phase completion percentages
   - Add or update implementation status for components
   - Add notes on implementation approach and decisions
   - Document best practices discovered during implementation
   - Note any challenges overcome and solutions implemented

3. Update implementation specification documents:
   - Mark completed items with ✅ or strikethrough but preserve original requirements
   - Add notes on implementation details where appropriate
   - Add references to implemented files and classes
   - Update any implementation guidance based on experience

4. Update CLAUDE.md and README.md if necessary:
   - Add new best practices
   - Update project status
   - Add new implementation guidance
   - Document known issues or limitations
   - Update usage examples to include new functionality

5. Document new testing procedures:
   - Add details on test files created
   - Include test running instructions
   - Document test coverage
   - Explain testing approach for complex components

## Documentation Formatting and Structure

1. Maintain consistent documentation style:
   - Use clear headings and sections
   - Include code examples where helpful
   - Use status indicators (✅, ⚠️, ❌) consistently
   - Maintain proper Markdown formatting

2. Ensure documentation completeness:
   - Cover all implemented features
   - Include usage examples
   - Document API changes or additions
   - Include troubleshooting guidance for common issues

## Guidelines

- DO NOT CREATE new specification files
