feat(cli): ship standalone binaries for installs without Node.js - #2137
Merged
Merged
Conversation
Build per-platform `openspec` executables with `bun build --compile`, smoke-test them on Linux/macOS/Windows in CI, and attach every target to each published GitHub release with SHA256SUMS. The binary has no package directory, so the build bundles package.json (createRequire calls become static requires) and embeds schemas/, which the entry writes to a content-hashed data-dir folder on first run.

Explanation
The PR satisfies the coding objective in [
#2055]. It adds standalone binaries for Linux glibc and musl, macOS, and Windows on x64 and arm64. The shell and PowerShell installers select assets, verify SHA-256 checksums, stage files, and install without Node.js. The binary build embeds schemas and required package data. Runtime hooks support schema resolution and installer-based upgrades from the binary location. The workflow builds, smoke-tests, and runs CLI tests for each asset before release upload. The issue does not impose a coding requirement for macOS notarization, and the PR records it as excluded.
Full details: Out of Scope Changes check
-
Explanation
The changes remain within [
#2055]. The build scripts, installers, binary entrypoint, resolver and version hooks, tests, documentation, and release workflow support standalone installation, runtime compatibility, upgrades, or release validation. No unrelated change is demonstrated by the reviewed evidence.

Review comments at @.github/workflows/binaries.yml:
- Around line 92-95: Update the version check in the release workflow to remove
the leading v from TAG and compare the result exactly with the version reported
by dist-bin/openspec-linux-x64, replacing the current suffix match while
preserving the existing error and exit behavior.
Review comments at @scripts/binary/build.mjs:
- Line 43: Make the schema hash generation deterministic by sorting the entries
in files before serializing them for createHash. Update the hash calculation
around sortedFiles and preserve the existing SHA-256 and truncated output
behavior.
Review comments at @scripts/binary/entry.mjs:
- Around line 35-38: Update the compiled entrypoint to import and invoke the
exported runCli function after setPackageSchemasDir(extractSchemas()), ensuring
--version and normal commands are handled.

L341: * Profiles keep working as your code changes. Functions are matched by a hash of their syntax, not by name or position, so a profile from last week's build still applies. Commit it or cache it if recording on every build is inconvenient. Functions that changed since the recording are placed right after the recorded ones.
L342: * One profile works for every `--target`.
L343: * Several profiles cover several ways of starting the app: `--bytecode-order=interactive.order,oneshot.order`. List the most common one first.
L344: * Only the layout changes. The program behaves the same, and builds stay reproducible. The profile contains hashes, not source code.
L345: * `%p` in `BUN_BYTECODE_ORDER_OUT` becomes the process id. `Worker` threads are recorded too.
L346: * `bytecodeOrderStats()` from `bun:jsc` reports how many loaded functions the profile covered (`hot`) or missed (`cold`). A growing share of `cold` means it is time to record again.
L347: ### JIT policy【32†#】
L348:
L349: Code that only runs during startup rarely pays back the time the JIT spends compiling it. `--compile-jit-policy <n>` (`compile: { jitPolicy: n }` in `Bun.build`) starts the executable with JavaScriptCore's tier-up thresholds multiplied by `n`, so startup code stays in the interpreter longer. The default, `1`, is the normal JIT policy. The scale stays in effect until the program calls `Bun.unsafe.setJITPolicy(1)`, which it should do once it is interactive:
L350: build.ts
L351:
L352: `await Bun.build({
L353: entrypoints: ["./app.ts"],
L354: compile: { outfile: "./myapp", jitPolicy: 8 },

L112: Use Bun's utility functions to work with the runtime
L113:
L114: ## `Bun.version`【88†#】
L115:
L116: A `string` containing the version of the `bun` CLI that is currently running.
L117:
L118: terminal
L119:
L120: `Bun.version;
L121: // => "1.3.3"`
L122:
L123: ## `Bun.revision`【89†#】
L124:
L125: The git commit of 【90†Bun†github.com】 that was compiled to create the current `bun` CLI.
L126:
L127: terminal
L128:
L129: `Bun.revision;
L130: // => "f02561530fda1ee9396f51c8bc99b38716e38296"`
L131:
L132: ## `Bun.env`【91†#】
L133:
L134: An alias for `process.env`.
L135: ## `Bun.main`【92†#】
L136:
L137: An absolute path to the entrypoint of the current program (the file you executed with `bun run`).
L138:
L139: script.ts
L140:
L141: `Bun.main;
L142: // /path/to/script.ts`
L143:
L144: Use this to determine whether a script is running directly or another script is importing it.
L145:
L146: `if (import.meta.path === Bun.main) {
L147: // this script is being directly executed
L148: } else {
L149: // this file is being imported from another script
L150: }`
L151: This check is analogous to the 【93†`require.main = module` trick†stackoverflow.com】 in Node.js.
L152: ## `Bun.sleep()`【94†#】
L153:
L154: `Bun.sleep(ms: number)`
L155:
L156: Returns a `Promise` that resolves after the given number of milliseconds.
L157:
L158: `console.log("hello");
L159: await Bun.sleep(1000);
L160: console.log("hello one second later!");`
L161:
L162: Alternatively, pass a `Date` object to receive a `Promise` that resolves at that point in time.
L163:
L164: `const oneSecondInFuture = new Date(Date.now() + 1000);
L165:
L166: console.log("hello");
L167: await Bun.sleep(oneSecondInFuture);
L168: console.log("hello one second later!");`
L169: ## `Bun.sleepSync()`【95†#】
L170:
L171: `Bun.sleepSync(ms: number)`
L172:
L173: A blocking synchronous version of `Bun.sleep`.
L174:
L175: `console.log("hello");
L176: Bun.sleepSync(1000); // blocks thread for one second
L177: console.log("hello one second later!");`
L178: ## `Bun.which()`【96†#】
L179:
L180: `Bun.which(bin: string)`
L181:
L182: Returns the path to an executable, similar to typing `which` in your terminal.
L183:
L184: `const ls = Bun.which("ls");
L185: console.log(ls); // "/usr/bin/ls"`
L186:
L187: By default Bun looks at the current `PATH` environment variable to determine the path. To configure `PATH`:
L188:
L189: `const ls = Bun.which("ls", {
L190: PATH: "/usr/local/bin:/usr/bin:/bin",
L191: });
L192: console.log(ls); // "/usr/bin/ls"`

L397: Once the CommonJS module is successfully evaluated, Bun creates a Synthetic Module Record with the `default` ES Module 【112†export set to `module.exports`†github.com】. If `module.exports` is an object, Bun also re-exports its keys as named exports.
L398:
L399: Bun's bundler works differently: it wraps the CommonJS module in a `require_${moduleName}` function which returns the `module.exports` object.
L400:
L401: * * *
L402: ## `import.meta`【113†#】
L403:
L404: The `import.meta` object exposes information about the current module. It's part of the JavaScript language, but its contents are not standardized: each "host" (browser or runtime) implements its own properties on the `import.meta` object.
L405:
L406: Bun implements the following properties.
L407: /path/to/project/file.ts
L408:
L409: `import.meta.dir; // => "/path/to/project"
L410: import.meta.file; // => "file.ts"
L411: import.meta.path; // => "/path/to/project/file.ts"
L412: import.meta.url; // => "file:///path/to/project/file.ts"
L413:
L414: import.meta.main; // `true` if this file is directly executed by `bun run`
L415: // `false` otherwise
L416:
L417: import.meta.resolve("zod"); // => "file:///path/to/project/node_modules/zod/index.js"`
L418: Property | Description
L419: --- | ---
L420: `import.meta.dir` | Absolute path to the directory containing the current file, e.g. `/path/to/project`. Equivalent to `__dirname` in CommonJS modules (and Node.js)
L421: `import.meta.dirname` | An alias to `import.meta.dir`, for Node.js compatibility
L422: `import.meta.env` | An alias to `process.env`.
L423: `import.meta.file` | The name of the current file, e.g. `index.tsx`
L424: `import.meta.path` | Absolute path to the current file, e.g. `/path/to/project/index.ts`. Equivalent to `__filename` in CommonJS modules (and Node.js)
L425: `import.meta.filename` | An alias to `import.meta.path`, for Node.js compatibility
L426: `import.meta.main` | Indicates whether the current file is the entrypoint to the current `bun` process: `true` if `bun run` executes it directly, `false` if it's imported
L427: `import.meta.resolve` | Resolve a module specifier (e.g. `"zod"` or `"./file.tsx"`) to a url. Equivalent to 【114†`import.meta.resolve` in browsers†developer.mozilla.org】. Example: `import.meta.resolve("zod")` returns `"file:///path/to/project/node_modules/zod/index.js"`
L428: `import.meta.url` | A `string` url to the current file, e.g. `file:///path/to/project/index.ts`. Equivalent to 【115†`import.meta.url` in browsers†developer.mozilla.org】

Code that only runs during startup rarely pays back the time the JIT spends compiling it. `--compile-jit-policy <n>` (`compile: { jitPolicy: n }` in `Bun.build`) starts the executable with JavaScriptCore's tier-up thresholds multiplied by `n`, so startup code stays in the interpreter longer. ... new Worker(new URL("./my-worker.ts", import.meta.url)); ... The embedded files live under `import.meta.dir` at runtime and are reachable via `node:fs` (`existsSync`, `statSync`, `readdirSync`, `readFileSync`) and `Bun.file()`.
## Build-time constants#
Use the `--define` flag to inject build-time constants into your executable, such as version numbers, build timestamps, or configuration values:
CLI JavaScript
terminal
`bun build --compile --define BUILD_VERSION='"1.2.3"' --define BUILD_TIME='"2024-01-15T10:30:00Z"' src/cli.ts --outfile mycli`
build.ts
`await Bun.build({
entrypoints: ["./src/cli.ts"],
compile: {
outfile: "./mycli",
},
define: {
BUILD_VERSION: JSON.stringify("1.2.3"),
BUILD_TIME: JSON.stringify("2024-01-15T10:30:00Z"),
},
});`
Bun inlines these constants into the binary at build time, so they cost nothing at runtime and enable dead code elimination.
For more examples and patterns, see the Build-time constants guide.
## Deploying to production#
Compiled executables reduce memory usage and improve Bun's start time.
Normally, Bun reads and transpiles JavaScript and TypeScript files on `import` and `require`. This is part of what makes so much of Bun "just work", but it's not free: reading files from disk, resolving paths, parsing, transpiling, and printing source code costs time and memory.
Compiled executables move that cost from runtime to build time.
When deploying to production, we recommend the following:
CLI JavaScript
terminal
`bun build --compile --minify --sourcemap ./path/to/my/app.ts --outfile myapp`
build.ts
`await Bun.build({
entrypoints: ["./path/to/my/app.ts"],
compile: {
outfile: "./myapp",
},
minify: true,
sourcemap: "linked",
});`
### Bytecode compilation#
To improve startup time, enable bytecode compilation:
CLI JavaScript
terminal
`bun build --compile --minify --sourcemap --bytecode ./path/to/my/app.ts --outfile myapp`
build.ts
`await Bun.build({
entrypoints: ["./path/to/my/app.ts"],
compile: {
outfile: "./myapp",
},
minify: true,
sourcemap: "linked",
bytecode: true,
## Act as the Bun CLI#
New in Bun v1.2.16
Set the `BUN_BE_BUN=1` environment variable to run a standalone executable as if it were the `bun` CLI itself. The executable ignores its bundled entrypoint and exposes the full `bun` CLI instead.
For example, consider an executable compiled from this script:
terminal
`echo "console.log(\"you shouldn't see this\");" > such-bun.js
bun build --compile ./such-bun.js`
`[3ms] bundle 1 modules
[89ms] compile such-bun`
Normally, running `./such-bun` with arguments executes the script.
terminal
`# Executable runs its own entrypoint by default
./such-bun install`
`you shouldn't see this`
However, with the `BUN_BE_BUN=1` environment variable, the executable acts like the `bun` binary:
terminal
`# With the env var, the executable acts like the `bun` CLI
BUN_BE_BUN=1 ./such-bun install`
`bun install v1.2.16-canary.1 (1d1db811)
Checked 63 installs across 64 packages (no changes) [5.00ms]`

# Single-file executable
Generate standalone executables from TypeScript or JavaScript files with Bun
Bun's bundler implements a `--compile` flag for generating a standalone binary from a TypeScript or JavaScript file.
CLI JavaScript
terminal
`bun build ./cli.ts --compile --outfile mycli`
build.ts
`await Bun.build({
entrypoints: ["./cli.ts"],
compile: {
outfile: "./mycli",
},
});`
cli.ts
`console.log("Hello world!");`
Bun bundles `cli.ts` into an executable you can run directly:
terminal
`./mycli`
`Hello world!`
Bun bundles all imported files and packages into the executable, along with a copy of the Bun runtime. All built-in Bun and Node.js APIs are supported.
## Cross-compile to other platforms#
Use the `--target` flag to compile your standalone executable for a different operating system, architecture, or version of Bun than the machine you're running `bun build` on.
To build for Linux x64 (most servers):
CLI JavaScript
target: "bun-windows-x64",
outfile: "./myapp", // .exe added automatically
},
});`
To build for Windows arm64:
CLI JavaScript
terminal
`bun build --compile --target=bun-windows-arm64 ./path/to/my/app.ts --outfile myapp
# note: if no .exe extension is provided, Bun adds it automatically for Windows executables`
build.ts
`await Bun.build({
entrypoints: ["./path/to/my/app.ts"],
compile: {
target: "bun-windows-arm64",
outfile: "./myapp", // .exe added automatically
},
});`
To build for macOS arm64:
CLI JavaScript
terminal
`bun build --compile --target=bun-darwin-arm64 ./path/to/my/app.ts --outfile myapp`
build.ts
`await Bun.build({
entrypoints: ["./path/to/my/app.ts"],
compile: {
target: "bun-darwin-arm64",
outfile: "./myapp",
},
});`
To build for macOS x64:
CLI JavaScript
terminal
`bun build --compile --target=bun-darwin-x64 ./path/to/my/app.ts --outfile myapp`
build.ts
`await Bun.build({
entrypoints: ["./path/to/my/app.ts"],
compile: {
target: "bun-darwin-x64",
outfile: "./myapp",
},
});`
### Supported targets#
The segments of the `--target` value can appear in any order, as long as they're delimited by `-`.
--target | Operating System | Architecture | Libc
--- | --- | --- | ---
bun-linux-x64 | Linux | x64 | glibc
bun-linux-arm64 | Linux | arm64 | glibc
bun-windows-x64 | Windows | x64 | -
bun-windows-arm64 | Windows | arm64 | -
bun-darwin-x64 | macOS | x64 | -
bun-darwin-arm64 | macOS | arm64 | -
bun-linux-x64-musl | Linux | x64 | musl
bun-linux-arm64-musl | Linux | arm64 | musl
On x64, Bun ships a single binary that targets Nehalem (SSE4.2) and selects AVX2/AVX-512 code paths at runtime. The `-baseline` and `-modern` target suffixes are still accepted for backward compatibility and resolve to the same binary; you do not need to pick one based on the destination CPU.

## Description

Issue body actions
### What version of Bun is running?
1.1.25-canary.36+d55b5cc16
### What platform is your computer?
Darwin 23.6.0 arm64 arm
### What steps can reproduce the bug?
Create child directory with `compile.ts` in it. Put `test.txt` next to it.
// dir/compile.ts
import { createRequire } from "module"
console.log(Bun.resolveSync("./test.txt", import.meta.url))
console.log(createRequire(import.meta.url).resolve("./test.txt"))
From outside of `dir/`, you can see that `bun dir/compile.ts` correctly resolves to `./text` relative to `dir/compile.ts`, i.e. `dir/test.txt`.
When you compile it, even without `--outfile`:
`bun build --compile compile.ts
`
And then exit the directory and run the binary, it will error:
`error: Cannot find module "./test.txt" from "file:///$bunfs/root/compile"
`
If you're inside the directory, i.e. cwd is `.` relative to `import.meta.url`, the binary will work. If `test.txt` is in cwd, it will work. But it is not correctly resolved relative to the binary itself.
### What is the expected behavior?
The `./file` case should work for binaries, including for `createRequire(import.meta.url).resolve`.
Running the binary from outside the directory should be like `bun compile.ts`, and resolve relative to the file.
### What do you see instead?
The binary tries to resolve relative to the current working directory. If you move `test.txt` to cwd and run the binary from another folder, it will work.
### Additional information
Related:
* bun build --compile fails if dependency uses wasm #6567. Should be closed in favor of this issue, is not related to Wasm in general but a more general pattern that comes up with Yoga specifically, with its `createRequire(import.meta.url).resolve("./yoga.wasm")` statement in bundle. You can compile the binary, move `yoga.wasm` next to it, and then, only if you are in that directory, run the program. It only working from inside the directory is what this issue is about.
* Compile error on 3-line Ink cli program #2034. People are posting the same issue with Yoga, from Ink.

<excerpt>citeturn0search0 [wordlim: 200] Crawled: last week; new Worker(new URL("./my-worker.ts", import.meta.url)); new Worker(new URL("./my-worker.ts", import.meta.url).href); ... That means if the executable is at `/usr/bin/hello` and the user's terminal is in `/home/me/Desktop`, Bun looks for `/home/me/Desktop/my.db`. ... You can then read this embedded file using `Bun.file()` or Node.js `fs` APIs. ... ```bash terminal icon="terminal" # Custom icon bun build --compile --windows-icon=path/to/icon.ico ./app.ts --outfile myapp
## Worker
To use workers in a standalone executable, add the worker's entrypoint to the build:
```bash terminal icon="terminal" bun build --compile ./index.ts ./my-worker.ts --outfile myapp ``` ```ts build.ts icon="/icons/typescript.svg" await Bun.build({ entrypoints: ["./index.ts", "./my-worker.ts"], compile: { outfile: "./myapp", }, }); ```
Then, reference the worker in your code:
console.log("Hello from Bun!");
// Any of these will work:
new Worker("./my-worker.ts");
new Worker(new URL("./my-worker.ts", import.meta.url));
new Worker(new URL("./my-worker.ts", import.meta.url).href);
When you add multiple entrypoints to a standalone executable, Bun bundles each one separately into the executable.
We may eventually detect statically-known paths in `new Worker(path)` and bundle them automatically. For now, you need to list the worker file as an entrypoint, as in the earlier example.
If you use a relative path to a file not included in the standalone executable, Bun loads that path from disk relative to the process's current working directory, and errors if it doesn't exist.
## SQLite
You can use `bun:sqlite` imports with `bun build --compile`.
By default, Bun resolves the database relative to the current working directory of the process.
import db from "./my.db" with { type: "sqlite" };
console.log(db.query("select * from users LIMIT 1").get());
That means if the executable is at `/usr/bin/hello` and the user's terminal is in `/home/me/Desktop`, Bun looks for `/home/me/Desktop/my.db`.
cd /home/me/Desktop
./hello
## Embed assets & files
Standalone executables can embed files directly into the binary, so a single executable can ship images, JSON configs, templates, or any other assets your application needs.
### How it works
Use the `with { type: "file" }` import attribute to embed a file:
import icon from "./icon.png" with { type: "file" };
console.log(icon);
// During development: "./icon.png"
// After compilation: "/$bunfs/root/icon-a1b2c3d4.png" (internal path)
The import returns a path string that points to the embedded file. At build time, Bun:
1. Reads the file contents
2. Embeds the data into the executable
3. Replaces the import with an internal path (prefixed with `/$bunfs/`)
You can then read this embedded file using `Bun.file()` or Node.js `fs` APIs.
### Reading embedded files with Bun.file()
`Bun.file()` is the recommended way to read embedded files:
import icon from "./icon.png" with { type: "file" };
import { file } from "bun";
// Get file contents as different types
const bytes = await file(icon).arrayBuffer(); // ArrayBuffer
const text = await file(icon).text(); // string (for text files)
const blob = file(icon); // Blob
// Stream the file in a response
export default {
fetch(req) {
return new Response(file(icon), {
headers: { "Content-Type": "image/png" },
});
},
};

Call runCli() from the compiled entrypoint.
The dynamic import only defines the Commander program. In the compiled Bun bundle, the CLI module's import.meta.url is an internal /$bunfs/... URL, so its direct-execution check does not match the executable path in process.argv[1]. The binary therefore exits without handling --version or normal commands.
Suggested fix

…ta dirs - Extract the built-in schemas lazily, only when a command needs them, so --version and list work even when nothing is writable. - Verify the extracted copy on every start and replace it if it was edited, partly deleted, or replaced by a file, instead of failing forever. - Fall back to a private temp copy when the data dir is read-only, and fail with a plain CLI error when no location is writable. - smoke.sh now runs the binary renamed, from a path with a space and non-ASCII characters, and checks the repair path.

- Ship 8 assets: glibc and musl Linux, macOS, and Windows on x64 and arm64. x64 uses Bun's baseline builds, which do not require AVX2. - CI builds once, then smoke-tests each asset on a native runner (Alpine 3.17 for musl, plus PowerShell and cmd on Windows), and attaches assets to a release only when all pass. Release builds skip dependency caches. - install.sh picks the asset for the machine (arch, musl, Rosetta), checks it against SHA256SUMS, and avoids the macOS quarantine that kills unnotarized browser downloads. - Build unminified so crash traces from binary users name real functions.

`openspec update` told binary users to run `npm install -g`, which needs the Node.js they don't have. The binary now marks itself at startup and: - prints the installer pointed at the binary's own directory (a PowerShell download on Windows), so the new copy replaces the old one; - reports `(standalone)` and its location in `openspec version`; - never feeds a directory to the npm self-upgrade logic. getInstallDir() now resolves package.json from import.meta.url at runtime. require.resolve was resolved by the bundler at build time, baking the build machine's repo path into the binary; on the build machine that path is a git checkout, which also silently skipped the update check. npm and pnpm installs resolve to the same (symlink-resolved) directory as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Fail the build if a binary embeds the build machine's path. - Hash schemas in sorted order so builds are reproducible, and refuse schema files that are not UTF-8 text instead of corrupting them. - Match the release tag to package.json exactly (v1.2.3 or the scoped @fission-ai/openspec@1.2.3 tag); a suffix match let v11.0.0 pass 1.0.0. - Skip the merge queue: the PR run covers the change and a release re-verifies before upload. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Detect glibc first, so a glibc distro with musl installed alongside no longer gets the Alpine build. - Stage the download in the install dir: works when /tmp is noexec and replaces an existing copy atomically. - Run everything from main(), so a truncated `curl | sh` does nothing. - Clear errors for unset HOME, an unwritable dir, and macOS older than 13; accept OPENSPEC_VERSION with or without the leading v. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The assistant install prompt and install.md now offer the standalone binary, with the user's confirmation, instead of stopping when Node is missing or too old. Also states macOS 13+ / Windows 10+ and when the schema copy is kept. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Preserve nonstandard executable names during Unix upgrades.
If a user runs a downloaded asset without renaming it, the Unix upgrade command passes only its directory to install.sh. The installer writes $dir/openspec, so the executable at the original path remains unchanged. The documented manual-install path requires renaming the asset, which limits this issue to manual installs that skip that step.

install.ps1 is the Windows counterpart of install.sh: `irm .../install.ps1 | iex` in Windows PowerShell 5.1 or PowerShell 7. It picks the x64 or ARM build from the OS architecture, checks SHA256SUMS, installs to %LOCALAPPDATA%\Programs\openspec and appends that folder to the user PATH once. The PATH is read and written raw so %VAR% entries keep expanding. It throws rather than exits, so a failure never closes the user's window. A binary on Windows now gets this installer as its upgrade advice instead of an unverified download. Both installers suggest npm when a download fails. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
OPENSPEC_TEST_BINARY points runCLI at a standalone binary instead of `node dist/cli/index.js`, and scripts/binary/e2e.sh runs every CLI test file that way (refusing to run if it finds none). CI now runs it on all eight native runners, with Alpine in a node:22-alpine container as a non-root user, and tests install.ps1 in PowerShell 7 and Windows PowerShell 5.1, including that it keeps %VAR% user PATH entries intact. Four tests encoded the source-checkout answer; they now expect what each runtime should report (`standalone`, and the binary's schema copy in the data dir). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
README, the installation guide, getting started, the AI setup prompt and install.md now lead with the one-line installers; npm, Homebrew and the other package managers stay as the alternative, with the Node.js 20.19+ requirement moved to them. Adds a minor changeset so the release that ships the binaries announces them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Line 21: Update the manual installation instructions to add a `chmod +x
openspec` step for macOS and Linux after downloading and renaming the
executable; keep the Windows instructions unchanged.
- Around line 42-46: Update the existing-installation branch keyed by `openspec
--version` to detect the installation source and offer its matching update
method, or ask the user to choose, rather than defaulting to the standalone
installer. Apply the same behavior to the corresponding `install.md`
instructions.
Review comments at @README.md:
- Line 120: Update the README installation sentence and the corresponding Alpine
entry in the installation table in docs/installation.md to clarify that Alpine
requires libstdc++ and libgcc; avoid claiming the binary has no dependencies on
Alpine, while preserving the statement that Node.js is not required.
Review comments at @scripts/binary/install.ps1:
- Line 36: Resolve `$dir` to an absolute path in the installer before creating
the directory and updating the user PATH, so a relative `OPENSPEC_INSTALL_DIR`
is stored as an absolute PATH entry.
Review comments at @test/helpers/run-cli.ts:
- Around line 144-146: Update runCLI’s RunCLIResult.command and timeout-error
reporting to build the displayed invocation from the resolved command and
commandArgs, so when testBinary is set the output names the binary that actually
ran.

PSScriptAnalyzer flags an empty catch block, which failed the Windows verify jobs before the CLI test suite ran. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Upgrade advice passes the binary's own file name when it isn't the default (`openspec-darwin-arm64` kept as downloaded), so the installer replaces that file instead of writing a second one beside it. Both installers take OPENSPEC_INSTALL_NAME for this. - Both installers resolve a relative OPENSPEC_INSTALL_DIR first, so the PATH advice (and the Windows user PATH entry) work from any directory. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With OPENSPEC_TEST_BINARY set, failures named `node dist/cli/index.js` instead of the binary under test. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The setup prompt and install.md update an existing install with the command `openspec version --check` prints for it, instead of offering the binary installer and leaving two copies on PATH. - The PATH step covers where the standalone installer puts the binary. - Alpine's libstdc++ prerequisite is stated where "no Node.js" is claimed, and manual Unix installs include `chmod +x`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…switch The live site builds from docs-lab, so its installation page now leads with the one-line installers, keeps npm and the other package managers (with the Node.js prerequisite) as the alternative, and covers the binary in updating and uninstalling. New "Switch from npm to the standalone install" section: install the binary, remove the npm copy (it otherwise keeps running first on PATH), then check `openspec version` prints `(standalone)`. Settings and projects carry over. Rehearsed end to end on macOS. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Following the npm-to-native pattern of tools like Claude Code: one command installs the standalone binary, and nothing is forced. - From a package manager: runs the release installer (same SHA256SUMS check as the documented one-liners), then prints the command that removes the old copy (npm, pnpm, yarn, bun, volta, or Homebrew's formula) and which copy `openspec` now runs. It never removes the old copy itself. - From the binary: reinstalls it in place under its own name, so the binary's upgrade advice is now simply `openspec install` (or its full path when `openspec` on PATH is a different copy). The installer is fetched with curl/wget or PowerShell, like the one-liners, so proxies behave the same, and saved to a file first so a failed download cannot look like success. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…l exists After `openspec update`, a global npm/pnpm/yarn/bun/volta/Homebrew install prints one line pointing at `openspec install`, once per machine (standaloneTipSeen in the global config). Never in CI, never for the binary, project installs, npx or source checkouts, and deferred rather than used up when stderr is not a terminal, so agents never consume it. Reuses the completion tip's safe config write. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
`openspec install` runs the installer from the very exe it replaces, and Windows cannot overwrite a running exe. The installer now renames the old copy aside (allowed while it runs), moves the new one in, deletes the old one now or on the next install, and restores it if the move fails. It also clears any download mark on the new exe (Unblock-File). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…inaries - Every verify runner (Alpine in its container) runs install-check.sh: the Node build switching to the binary, and the binary reinstalling itself twice in place, against this build served locally. - Releases get signed build-provenance attestations (actions/attest, pinned), verifiable with `gh attestation verify`. They stand in for code signing until notarization lands, and run after the upload so a first-time problem cannot hold binaries back. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The switch steps start with `openspec install`, which prints the removal command for the old copy; switching is stated as optional. - The CLI reference documents `openspec install` and the `standalone` scope. - The setup prompt and install.md mention the standalone install once to package-manager users, without pushing it. - New "Verify a download" note for `gh attestation verify`.

Merging main's `update --dry-run` (#2109) interleaved the two commands' catch blocks: update's JSON-aware failure handling landed in `install`, which failed the build. Both are restored; against main, index.ts now differs only by the standalone notice and the `install` command. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The installer URL no longer becomes part of a command line: macOS and Linux get it as an argument to a fixed sh script, Windows as an environment variable read by a fixed PowerShell line. - OPENSPEC_DOWNLOAD_URL must be https, or http to localhost only, in `openspec install` and both installers. The binary and SHA256SUMS come from the same place, so a remote plain-HTTP source could swap both. - A test wrote to a predictable temp path; it now uses mkdtemp. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A release can be retagged while the Binaries workflow runs (the scoped @fission-ai/openspec@x.y.z tag corrected to vx.y.z), which made the upload look up a tag the release no longer has. The upload now finds the release by id and uses its current tag. The release skill now also checks that the binaries, SHA256SUMS and both installers are attached, and says to re-run binaries.yml (never npm) if they are missing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Two problems, both from trusting a string instead of checking the thing: - Every release briefly broke the default install, and a failed Binaries run broke it for good. The installers hung off `releases/latest`, which GitHub moves the moment a release is published, about ten minutes before its binaries are attached. Now the installers are served from main (always present), and "latest" means the newest stable release that has its SHA256SUMS, which is uploaded last. Until then they install the previous release and say so; with no complete release they fail clearly and point at npm. A pinned OPENSPEC_VERSION still installs exactly that release. - install.sh matched OPENSPEC_DOWNLOAD_URL by prefix, so `http://localhost:80@evil.example/` passed as localhost while connecting to evil.example over plain HTTP. It now parses the host, refuses any user part, and requires a numeric port; install.ps1 and `openspec install`, which already parsed the host, also refuse a user part now, so all three apply the same rule, including to the new OPENSPEC_RELEASES_URL. test/binary-installer.test.ts runs the real install.sh against a local stand-in for the releases page; all 16 cases fail on the previous script. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- The release upload attaches the binaries first and SHA256SUMS last, so a release with SHA256SUMS is complete. The installers are no longer release assets; they are served from main. - The Windows verify jobs run install.ps1, in PowerShell 5.1 and 7, against a stand-in releases page whose newest release is incomplete, and check it installs the previous one with a note and refuses a localhost URL whose real host is remote. - Docs, install.md, the changeset and the release skill use the new installer URLs and say what "newest release" means.

Status: LGTM, safe to merge. Publish a release right after merging (see below).
Why: today OpenSpec only installs through npm, so you need Node.js first (#2055).
What it does
Installing OpenSpec becomes one line, with no Node.js needed:
openspecfor macOS, Linux (including Alpine, withlibstdc++) and Windows, on Intel/AMD and ARM, plus a checksum file.main, so they always exist. They install the newest release whose files are all attached, rather than whatever GitHub calls "latest": for the ~10 minutes after a release is published (or for good, if its upload fails), they install the previous release and say so.Already on npm? Switching is offered, never forced (same pattern as Claude Code's move from npm to its native installer):
openspec installinstalls the standalone binary, then prints the exact command that removes the old copy (npm uninstall -g @fission-ai/openspec, or the pnpm, yarn, bun, Volta or Homebrew equivalent) and which copy now runs. It never removes the old copy itself.openspec update, package-manager users (npm, pnpm, yarn, bun, Volta, Homebrew) see one line, once per machine: "OpenSpec also comes as a standalone app that runs without Node.js. To switch, run 'openspec install'." It is never shown in CI, to agents (non-terminal output), or to binary users.openspec installis also the upgrade: it replaces the running binary in place, on Windows too.Settings and projects carry over, and nothing needs re-initializing.
How the binary is built
It is the npm package's own compiled code with a JavaScript runtime attached, packed into one file. Nothing is rewritten by hand.
pnpm install --frozen-lockfile), and runs the samepnpm buildthat produces the npm package'sdist/.bun build --compile(Bun 1.4.3, pinned) bundles thatdist/, its npm dependencies and the Bun runtime into one executable per platform. Bun is a build tool here only; users never install it.scripts/binary/build.mjs, ~100 lines):package.jsonandcross-spawnare bundled into the file, because a single file has no package folder to load them from at runtime. The build fails if it meets any code it doesn't know how to bundle.schemas/) are embedded. On first use they are written to the OpenSpec data folder (~/.local/share/openspec/binary-schemas/on macOS and Linux), checked on every run, and rewritten if anything changed them.package.json's version, or a download source that isn't HTTPS (the host is parsed, sohttp://localhost:80@evil.example/is refused).openspec installon its own OS and CPU. Only if all pass are the binaries attached to the GitHub release, withSHA256SUMSuploaded last; a release counts as complete once it hasSHA256SUMS.gh attestation verify openspec-darwin-arm64 --repo Fission-AI/OpenSpec. This is the verifiable trail until notarization and code signing land.The release build uses no caches, so nothing a pull request writes can end up in a release binary. The one real difference from npm is the engine: the binary runs on Bun instead of Node.js. That is exactly why the whole test suite is run against the binary, not just a smoke test.
Why it's safe
openspec installagainst all 8 binaries on real machines: Linux, Alpine, macOS Intel and ARM, Windows x64 and ARM. All pass (Windows skips the 31 tests written to skip there). A release only gets the binaries if all of it passes.test/binary-installer.test.tsruns the realinstall.shagainst a stand-in releases page: newest complete, newest still uploading, nothing complete, pinned version, betas and scoped tags, tampered file, and 10 URL tricks. CI runs the same fallback forinstall.ps1on Windows. Every case fails on the old script.openspec installcommand. How npm installs run and update is unchanged; the one shared rewrite (how the CLI finds its own install folder) was verified to give the same answer for npm and pnpm installs, also through symlinks.openspec installis run from the npm build (the switch) and by the binary on itself, twice (the upgrade), including replacing a running.exeon Windows. npm and Homebrew installs keep updating the way they were installed./tmpwithout exec rights and cut-off downloads are all handled and tested.When merging
Publish a release soon after merging; the included changeset (minor) makes it 1.15.0 and announces it. Until a release has binaries, the install commands stop with a clear message pointing to npm (tested against the real releases page today). From then on, releases never break them.
Nothing about npm publishing changes:
package.json,release-prepare.ymland the lockfile are untouched, and the npm package gains only the 6 compiled files of the new features (no binaries). The binaries go only to the GitHub Release, uploaded bybinaries.yml, which finds the release by its id, so they still land if its tag is corrected from@fission-ai/openspec@x.y.ztovx.y.zmeanwhile. The release skill now also checks that they are attached.That release is the first real run of the upload and attestation steps (everything before them runs on every PR). If the upload fails, npm is unaffected and installs keep working on the previous release: fix it and re-run the Binaries workflow with the release tag. Then run the two install commands once on a clean machine.
Notes

The installer clears the download mark, so installed copies run normally.openspec install, for passing a validated, environment-provided download URL tosh/PowerShell as data. They don't fail the check; a maintainer with security access can dismiss them as reviewed.Closes #2055
