## What it does

The skill treats the changelog as a release system, not a decorative modal. One authoritative ledger connects to production history, game-menu navigation and release verification. A version marks a successful production deployment, not a development commit.

It starts by inspecting the project: find the menu or pause state machine, the back action, input bindings, focus behavior and responsive layout. Then every place a version is displayed, plus release manifests and any existing changelog. From there it compares successful production deployments against source revisions. When evidence is incomplete, provenance is marked unknown in internal metadata or the work stops for clarification. Inventing dates, revisions or features is off the table.

For a new pre-1.0 game with no version scheme, the skill suggests starting at `0.9.0` and bumping the patch once per production release: `0.9.1`, `0.9.2` and so on. Opening the changelog is a reversible menu-state transition, and every close affordance — header toggle, visible X, bottom Back, controller cancel, Escape — routes through one function. On web-based games that means `aria-expanded`, `aria-controls` and a labelled panel. The displayed version is derived from the newest ledger entry instead of a second hand-written constant.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-game-changelog -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-game-changelog -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-game-changelog -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills build-game-changelog
```

2. **Manually: put the files in place**
- File: `.github/skills/build-game-changelog/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-game-changelog -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/game-development/build-game-changelog
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-game-changelog -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/MengTo/Skills/tree/HEAD/agent-skills/game-development/build-game-changelog/SKILL.md

## When to use it
- rebuild a release ledger from deployments and Git
- define version-bump rules for a game
- keep the displayed version in sync with the live build
- route every close affordance through one back action
- test changelog mechanics on desktop and mobile

## Example prompts
- add a changelog screen to the game with versions and release dates
- reconstruct release history from production deployments and Git
- check that the displayed version matches the live build

# Build Game Changelog

Build the changelog as a release system, not a decorative modal. Keep one authoritative ledger connected to production history, game-menu navigation, and release verification.

## Use this mental model

- The ledger is the public record of what players received.
- A version identifies a successful production release, not a development commit.
- The newest ledger entry defines the version shown throughout the game.
- Opening the changelog is a reversible menu-state transition.
- Every close affordance resolves through the same back action.
- A release is complete only after the live game proves the expected version and behavior.

## Start from truth

Inspect before editing:

1. Read repository instructions and preserve unrelated work.
2. Find the game’s menu or pause state machine, back action, input bindings, focus behavior, and responsive layout.
3. Find every displayed version, package version, build version, deployment sequence, release manifest, and existing changelog.
4. Query successful production deployments and their source revisions when available.
5. Compare deployment revisions to identify what players actually received.

Prefer repository, deployment, and live-runtime evidence over chat summaries or commit-message guesses. Do not invent missing release dates, source revisions, features, or version mappings.

## Define one release

Treat one successful player-visible production deployment as one changelog version.

- Do not bump for local commits, drafts, tests, failed builds, or saved-but-unpublished artifacts.
- Combine multiple commits shipped together into one version with several release notes.
- Give a separately deployed hotfix its own version.
- Describe player-visible outcomes, not implementation chores or raw commit messages.
