<p align="center"> <img src="assets/zx-vibes-logo.png" alt="ZX Vibes sticker logo" width="520"> </p> # ZX Vibes ZX Spectrum vibe-coding toolkit for coding agents and humans. `zx-vibes` packs the whole feedback loop into one modern toolchain: scaffold a project, assemble Z80, run it on a fast headless emulator (~130× real hardware), read the screen back as text or PNG, debug, and gate everything behind a single `zxs verify`. Claude, Codex, and any MCP-capable agent can drive it through the `zxs` CLI (every command speaks `--json`) or the bundled MCP server. Requires Node.js 20+. ## 五分钟制作乒乓球游戏 ```bash npm install -g zx-vibes zxs new pong cd pong zxs setup --agent claude # or: zxs setup --agent codex ``` `zxs new` doesn't scaffold an empty loop — it's a small playable game that already builds, runs, and passes `zxs verify`. The code your agent will edit is `src/main.asm`. `zxs setup` registers the MCP server and installs the agent playbook plus a knowledge pack (hardware reference, technique skills, CI-tested recipes) where your agent will find them. Now open your agent in the project — `claude` or `codex` — and paste: ```text Turn this project into Pong: two paddles (Q/A on the left, O/P on the right), a bouncing ball, and a score row. After every change, build and run it and look at the screen. Done means zxs verify passes. ``` While the agent works (and after), play the game yourself: ```bash zxs preview --watch # browser player; rebuilds and reloads on every edit ``` That's the entire workflow. The loop the agent follows — the same one you'd use by hand — is: 1. Edit `src/main.asm`. 2. `zxs build` 3. `zxs run --json` — check `status: "ok"`, `haltSynced: true`, and `frameBudget.overrunFrames: 0`. 4. `zxs screen --text` — look at the result. Never trust, always look. 5. `zxs verify` — the acceptance gate (build → run → screenshot → tests). ## 食谱 [`docs/recipes.md`](docs/recipes.md) is the task-shaped cookbook — start there when you (or your agent) want to: - **Create a game** — what the scaffold gives you and the tight iteration loop. - **Inspect the screen** — text OCR, PNG snapshots, declarative screen assertions. - **Enforce frame timing** — expose missed deadlines and profile T-states by routine. - **Anchor scenarios** — inject test state with `setup` and start input at `waitFor`. - **Assert sound** — prove the beeper actually beeped (`beeperEdges`). - **Debug hangs** — what the `di-halt`, `tight-loop`, and `pc-in-rom` verdicts mean. - **IM1 vs IM2** — when to leave the ROM interrupt handler behind, with a verified IM2 template to copy. ## 工具箱里有什么 - `zxs new` — scaffold a playable, verify-passing game (`--template game|platformer`). - `zxs build` / `run` / `test` / `verify` — the local loop; every command supports `--json`. - `zxs screen`, `regs`, `mem`, `disasm`, `step`, `trace`, `break`, `watch`, `symbols`, `coverage`, `gfx` — inspection and debugging. - `zxs preview` — browser playback of the current project, a blank 48K machine (`--blank`), or `.z80`/`.tap`/`.tzx`/`.bin` files. - `zxs state` — `.zxstate` sessions shared between the CLI and the MCP server, with `.z80`/`.tap`/`.scr` export. - `zxs-mcp` — MCP server for Claude, Codex, and other MCP-capable agents. - `zxasm` — the embedded TypeScript Z80 assembler/disassembler (no native dependencies), with optional `sjasmplus` support. - `zxs snapshot` / `scan` / `xref` — reverse-engineering extras behind `ZXS_REVENG=on`. - `@zx-vibes/cpu`, `@zx-vibes/ula`, `@zx-vibes/machine` — standalone emulator cores, pinned by the executable conformance suite in `dna/`. ## CLI 游览 The everyday commands: ```bash zxs doctor # check runtime assets and ambiguous PATH installs zxs build zxs run --frames 120 --keys "5:P*40" --screenshot screen.png zxs screen --text # the 32×24 grid as text — cheap eyes for agents zxs test tests zxs verify zxs preview game.z80 # also .tap/.tzx/.bin, or --blank for a clean 48K ``` Debugging and inspection: ```bash zxs regs zxs mem read 0x8000 --len 64 zxs disasm PC --count 12 zxs break add 0x8000 zxs watch add --write 0x5800-0x5aff zxs step 10 zxs trace --frames 5 --profile zxs state save session.zxstate zxs state export --z80 session.z80 zxs gfx screen --out screen.png zxs gfx attrs --out attrs.png ``` `zxs preview` serves the browser player with a visible build hash; `--watch` rebuilds and reloads on source changes. If the requested port is busy it picks the next free one and prints the URL (`--strict-port` to fail instead). `--detach`, `--list`, and `--stop` manage a background server; `--stop` only stops the tracked zx-vibes server. Click or press a key once to enable beeper audio; emulation continues while a hidden tab's rendering is suspended. `.sna` files are not supported yet and fail with a clear error. Reverse-engineering commands are gated behind an environment flag: ```bash ZXS_REVENG=on zxs snapshot info game.z80 ZXS_REVENG=on zxs scan --z80 game.z80 --opcode "ED B0" ZXS_REVENG=on zxs xref 0x5c00 --z80 game.z80 ZXS_REVENG=on zxs gfx find --z80 game.z80 ``` ## MCP 服务器和代理设置 `zxs-mcp` exposes structured build, run, screen, inspect, debug, keyboard, and state tools to MCP-capable agents. `zxs setup --agent <claude|codex>` does the wiring in one shot: - **claude** — merges a project `.mcp.json` (registering the `zx-vibes` server over the `zxs-mcp` bin) and installs a project skill under `.claude/skills/zx-vibes/`: the playbook plus the knowledge pack — `reference/` docs generated from the DNA, technique `skills/`, and CI-tested `recipes/`. - **codex** — writes `.codex/config.toml` (project-local, or `~/.codex/config.toml` with `--write-global`), `AGENTS.md`, and the same knowledge pack under `.codex/zx-vibes/`. Setup is idempotent and non-destructive: existing files are reported as `skipped` unless you pass `--force`, and other MCP servers in `.mcp.json` are left alone. The only content still reported under `deferred` is the worked-examples pack. No MCP? No problem — agents can drive the plain CLI; every command supports `--json`, and most inspection commands can read a session, a `.z80`, or a raw `--bin` without touching project state. ## 汇编程序后端 The default backend is `@zx-vibes/asm` — a TypeScript Z80 assembler and disassembler with no native dependencies, also usable standalone as `zxasm`: ```bash zxasm assemble src/main.asm -I lib --out-dir build zxasm disasm build/main.bin --org 0x8000 --count 32 zxasm doctor ``` The embedded backend keeps the name `spectral` in `zxs build --assembler`, and `spectral-asm` remains a bin alias for `zxasm`, for compatibility with older configurations. Need a `sjasmplus`-only feature? Install `sjasmplus` separately and select it with `zxs build --assembler sjasmplus` or `ZXS_ASSEMBLER=sjasmplus`. ## 在浏览器中试用模拟器 [`examples/`](examples/) contains three self-contained HTML demos of the `@zx-vibes/machine` core — open [`examples/index.html`](examples/index.html) straight from disk, no build step: - **Basic** — boots the real 48K BASIC ROM; the whole embed is three lines. - **Medium** — on-screen keyboard, program loading, pause/reset. - **Full** — `LOAD ""` real `.tap`/`.tzx` tapes (audible loading), `.z80` snapshots, sound, Kempston joystick. See [`examples/README.md`](examples/README.md) to embed the emulator in your own page. ## 打造工具箱 Clone the monorepo when you want to work on zx-vibes itself: ```bash git clone https://github.com/Alvaromah/zx-vibes.git cd zx-vibes pnpm install pnpm run verify # drift checks + conformance + build + typecheck + lint + tests ``` Layout: ```text dna/ Source-of-truth specs + executable conformance suite packages/asm/ @zx-vibes/asm assembler/disassembler (zxasm) packages/cpu/ @zx-vibes/cpu Z80 CPU core packages/ula/ @zx-vibes/ula ULA video/timing core packages/machine/ @zx-vibes/machine 48K machine integration packages/toolkit/ @zx-vibes/toolkit zxs CLI, MCP server, preview player packages/zx-vibes/ zx-vibes umbrella package and bin shims examples/ Browser demos of the machine core (prebuilt bundle) docs/ Task-shaped agent recipes (recipes.md) starters/ Installable starter projects; their source seeds `zxs new` scripts/ Drift checks and generators for the root gates ``` `dna/` is the project genome: self-contained normative specs for the Z80, ULA, Spectrum machine, and file formats (`domain/`), the project-invented product surface — CLI, MCP tools, `.zxstate`, config schema, assertions, exit codes (`product/`) — and an executable decider (`conformance/`). An implementation is correct iff it passes `pnpm run conformance:check`. Every fixture carries tier and provenance metadata; external suites (FUSE, ZEX) run through license-aware adapters. See [`dna/README.md`](dna/README.md). Tips for testing a local clone: - From the repo root (after `pnpm run build`), `pnpm zxs --help` runs the built CLI without the long path. - To use it from anywhere, alias the built entry point — `alias zxs="node /path/to/zx-vibes/packages/toolkit/bin/zxs.js"` — then `zxs new` / `zxs verify` in a scratch directory as if installed globally. - `pnpm run pack` writes tarballs to `.packs/`, but installing only the umbrella tarball is not an all-local install: packed `workspace:*` dependencies resolve to published versions. Use the alias workflow above, or a local registry when testing unpublished package metadata together. - Iterate on one package with `pnpm --filter @zx-vibes/toolkit test` (same for `asm`, `machine`, …). - The scaffold templates are generated from `starters/` — edit a starter, then run `pnpm run gen:scaffold-templates`; `check:drift` fails on any mismatch. See [`CONTRIBUTING.md`](CONTRIBUTING.md) for the pull-request checklist. Keep starter projects compatible with the embedded assembler unless a change is explicitly about optional `sjasmplus` support. ## 已发布软件包 | 软件包 | 版本 | 描述 | | --- | ---: | --- | | `zx-vibes` | `0.8.0` | 伞形软件包：`zx-vibes`、`zxs`、`zxs-mcp` 和 `zxasm` 二进制文件。 | | `@zx-vibes/toolkit` | `0.8.0` | `zxs` CLI、`MCP` 服务器和预览播放器实现。 | | `@zx-vibes/asm` | `0.3.0` | `zxasm` 汇编器/反汇编器（+ `spectral-asm` 别名）。 | | `@zx-vibes/cpu` | `0.1.0` | Z80 CPU 核心。 | | `@zx-vibes/ula` | `0.1.0` | ULA 视频/时序核心。 | | `@zx-vibes/machine` | `0.1.0` | 48K 机器集成（CPU + ULA + 磁带/IO）。 | `zxs --version` reports the toolkit version (the CLI is implemented by `@zx-vibes/toolkit`); `zxasm --version` reports the assembler version. The earlier `create-zx-vibes` and `@zx-vibes/emulator` packages are deprecated on npm — `zxs new` and the emulator core packages replace them. Each starter under `starters/` pins a `zx-vibes` dev dependency floor of `^0.8.0`, kept in sync with the umbrella package version by `pnpm run check:versions`. ## 持续集成与发布 CI runs `check:drift`, `conformance:check`, build, a clean `git diff`, typecheck, lint, and tests on Ubuntu, macOS, and Windows across Node 20 and 22. Releases use Changesets; the release workflow validates on both Node versions and only publishes when manually dispatched with `publish=true`. Root pnpm overrides pin patched floors for `form-data`, `js-yaml`, and `read-yaml-file`. ## 许可证 The zx-vibes source code is released under the MIT License — see [`LICENSE`](LICENSE).
