## What it does

It reads the latest tag with `git describe --tags --abbrev=0`, counts commits in `tag..HEAD` and inspects `git diff --name-status`. File paths tell it which parts of the project moved, and commit messages get sorted into Keep a Changelog sections: `Added`, `Changed`, `Fixed`, `Removed`, `Security`.

Then it looks for what to touch: `README.md`, `CHANGELOG.md`, `CONTRIBUTING.md`, the `docs/`, `documentation/` and `doc/` folders, plus `docs` directories inside plugins. Edits go through Read, Edit and Bash, keeping the structure and tone of existing files. Before writing anything it lists the files and asks for approval.

You need at least one release tag in the repository. With no tags the skill stops and asks you to create one, so check that first. It runs in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill docs-updater -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill docs-updater -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill docs-updater -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install giuseppe-trisciuoglio/developer-kit docs-updater
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill docs-updater -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/giuseppe-trisciuoglio/developer-kit --path plugins/developer-kit-core/skills/docs-updater
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add giuseppe-trisciuoglio/developer-kit --skill docs-updater -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/giuseppe-trisciuoglio/developer-kit/tree/HEAD/plugins/developer-kit-core/skills/docs-updater/SKILL.md

## When to use it
- turn commits between tags into changelog entries
- sync the README after a feature lands
- find documentation folders affected by code changes
- review the proposed edits before they are applied
- draft change notes for a pull request

## Example prompts
- update the docs for changes since the last release
- sync the README and CHANGELOG before I open a PR
- prepare changelog entries for the new version

# Universal Documentation Updater

Analyzes git changes since the latest release tag and updates the documentation files that should change with them.

## Overview

Use git history to identify release-relevant changes, then update `README.md`, `CHANGELOG.md`, and any relevant documentation folders. Keep the workflow focused on explicit user approval, precise edits, and repository-specific documentation structure.

## When to Use

Use this skill when:

- Preparing release notes or an `Unreleased` changelog update
- Syncing `README.md` or documentation after feature work lands
- Reviewing what changed since the last release before a PR or release

## Prerequisites

Before starting, verify that the following conditions are met:

```bash
# Verify we're in a git repository
git rev-parse --git-dir

# Check that git tags exist
git tag --list | head -5

# Verify documentation files exist
test -f README.md || echo "README.md not found"
test -f CHANGELOG.md || echo "CHANGELOG.md not found"
```

If no tags exist, inform the user that this skill requires at least one release tag to compare against.

## Instructions

### Phase 1: Detect Last Release Version

**Goal**: Identify the latest released version to compare against.

**Actions:**

1. Detect the comparison baseline and display it:

```bash
LATEST_TAG=$(git describe --tags --abbrev=0 2>/dev/null)

if [ -z "$LATEST_TAG" ]; then
    echo "No git tags found. This skill requires at least one release tag."
    echo "Please create a release tag first (e.g., git tag -a v1.0.0 -m 'Initial release')"
    exit 1
fi

CURRENT_BRANCH=$(git branch --show-current)
VERSION=$(echo "$LATEST_TAG" | sed -E 's/^[^0-9]*([0-9]+\.[0-9]+\.[0-9]+).*/\1/')

echo "Latest release tag: $LATEST_TAG"
echo "Version detected: $VERSION"
echo "Comparing: $LATEST_TAG -> $CURRENT_BRANCH"
```

### Phase 2: Perform Git Diff Analysis

**Goal**: Analyze all changes between the last release and current branch.

**Actions:**

1. Get the commit range and statistics:

```bash
# Get commit count between tag and HEAD
COMMIT_COUNT=$(git rev-list --count ${LATEST_TAG}..HEAD 2>/dev/null || echo "0")
echo "Commits since $LATEST_TAG: $COMMIT_COUNT"

# Get file change statistics
````

The third-party file has ended. Everything between the fbfb4cc1d2e83fa0 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
