Do not request Plan 9 or other unsupported GOOS/GOARCH shims. The five native prebuilt release targets are linux-x64, linux-arm64, macos-arm64, macos-x64, and windows-x64. Android/Termux is also a supported runtime through the documented android-arm64 source build and Linux artifact fallback. Other GOOS/GOARCH combinations are not a review criterion.

|

## 4. Common Review Blockers
|
||||
|
||||
These classes drive multi-round reviews. Fix them before requesting review:
|
||||
|
||||
- **Fresh base:** Rebase onto the current PR base (`main` or stacked target)
|
||||
before review. A stale head that rolls back mainline commits is a hard
|
||||
blocker, not a merge-time detail. Resolve conflicts by keeping upstream
|
||||
behavior unless the PR intentionally changes it.
|
||||
- **Platform truth:** Code and tests must pass on Linux, macOS, and Windows.
|
||||
Compare paths after canonicalization (physical/`EvalSymlinks` form); never
|
||||
assert raw `t.TempDir()` spellings (`/var` vs `/private/var` on macOS, short
|
||||
paths on Windows). Prefer one cross-platform function with small `GOOS`
|
||||
checks over duplicated helpers that drift.
|
||||
- **Supported targets only:** CONTRIBUTING.md names the five native prebuilt
|
||||
release artifacts (`linux-x64`, `linux-arm64`, `macos-arm64`, `macos-x64`,
|
||||
`windows-x64`) and the additional supported Android/Termux source-build and
|
||||
artifact-fallback path. Other `GOOS`/`GOARCH` combinations, including
|
||||
`plan9`, are unsupported and are not a review criterion. Do not block a PR
|
||||
for failing to compile on an unsupported `GOOS`/`GOARCH`. Tests may use
|
||||
`plan9` as a fixture for "unsupported".
|
||||
- **Security edges:** Keep secrets out of argv, env dumps, and logs. Redact
|
||||
success and error paths (including stderr). Fail closed on ownership, lease,
|
||||
and permission checks. Do not rely on pre-open path resolution
|
||||
(`EvalSymlinks` then open) for containment: that is a check-to-use race.
|
||||
Bind containment at open/use time with rooted or handle-relative,
|
||||
traversal-resistant APIs. If a no-follow API is used, apply it to every
|
||||
traversed component and enforce the platform's reparse-point protections;
|
||||
final-component-only no-follow is insufficient. On multi-step setup, roll back
|
||||
only what this run created; never destroy pre-existing resources you did
|
||||
not create; never report success when cleanup or unlock failed.
|
||||
- **Normalize before matching:** Any transform that REMOVES bytes without
|
||||
leaving a gap is also a reassembler, so it has to run before whatever matches
|
||||
on the result. Redacting by shape and then stripping control bytes lets a
|
||||
credential split by a NUL, an ESC or a C1 byte pass the patterns as two
|
||||
fragments and be rejoined on the way out; comparing a path against a form
|
||||
produced by the same resolver the kernel just used makes a redirect agree with
|
||||
itself. Strip, decode, or canonicalize first, then match. The unsplit value
|
||||
passing is not evidence, so the test needs a split case.
|
||||
- **Atomic shared state:** Write a complete temporary file, then atomically
|
||||
replace the destination so concurrent readers never see a partial write.
|
||||
Exclusive create or a write lock alone is not enough for readers. Serialize
|
||||
the full read-modify-write sequence for lockfiles and shared stores.
|
||||
- **Tests match the claim:** Every behavior or security-boundary change needs a
|
||||
regression test, including the failure path. Path-sensitive logic needs at
|
||||
least one non-Linux path case (or a hermetic fake that exercises the same
|
||||
normalization).
|
||||
- **Honest scope:** PR description, help text, and comments must match what
|
||||
shipped. Wire advertised entry points or shrink the claim. Do not bundle
|
||||
unrelated fixes. Do not widen security allowlists by name alone; check
|
||||
classification and side effects too.
|
||||
- **Host tool version floors:** Zero shells out to `git` and other host tools,
|
||||
and the project does not declare a minimum version for any of them. A flag,
|
||||
subcommand, or config key that is not long-established therefore raises that
|
||||
floor silently, and the failure on an older host is an unhelpful usage error
|
||||
rather than a clear message. Before adding one, check when it landed and say
|
||||
so where a caller would look. Record the floor for the exact subcommand you
|
||||
call, not for the flag in general: `--end-of-options` reached Git's shared
|
||||
parser in 2.24, but `git rev-parse` only accepted it from 2.30, and
|
||||
`git checkout` and `git reset` later still. Likewise `--show-current` is
|
||||
`git branch` 2.22, and `branch.autoSetupMerge=inherit` is 2.35. Then either
|
||||
keep a fallback for older versions or gate the call. A test that depends on a
|
||||
newer feature must skip below its floor instead of failing, and say which
|
||||
version it needs.
|
||||
- **Prove the test fails without the change:** A regression test earns its
|
||||
place only if it fails on the unfixed code, for the reason it claims. Run it
|
||||
both ways and quote the failure in the PR. The recurring miss is not a
|
||||
missing test but a test that never reaches the behavior it names, because an
|
||||
earlier guard rejects the input first, so it passes with and without the fix.
|
||||
When a test targets a specific layer, call that layer directly rather than
|
||||
relying on a public entry point that may refuse earlier.
|
||||
- **Hermetic tests:** Tests must not read or write the developer's real config,
|
||||
cache, or state directories. Redirect every root the code under test
|
||||
resolves, not just config. `os.UserConfigDir` and `os.UserCacheDir` read
|
||||
`XDG_CONFIG_HOME` and `XDG_CACHE_HOME` only on Linux and the BSDs. On macOS
|
||||
they derive from `HOME`, and on Windows from `%AppData%` and `%LocalAppData%`.
|
||||
Setting the XDG variables alone still leaves a macOS run writing to the real
|
||||
home, so set `HOME` as well, or take the directory as a parameter. Apply it to
|
||||
every test that reaches the same storage, not only the one where it was first
|
||||
needed; a test that passes on a clean machine and pollutes a real one is a
|
||||
blocker.
|
||||
- **Error codes vary by platform and by flag combination:** A check written
|
||||
against the code one target returns can be silently inert on another while
|
||||
still looking correct. `openat(O_DIRECTORY|O_NOFOLLOW)` on a symlink may
|
||||
report `ENOTDIR` or `ELOOP` depending on the platform, because the kernel can
|
||||
reject the directory mismatch before it ever resolves the link; accept both
|
||||
rather than assuming the one POSIX names. On Windows, `\\?\` and `\\.\`
|
||||
prefixes are not UNC paths, and an `NtCreateFile` information class must match
|
||||
the struct actually passed. Confirm the code each supported target returns
|
||||
instead of reasoning from the man page.

|

|

## Supported platforms
|
||||
|
||||
Zero publishes five native prebuilt artifacts from
|
||||
`.github/workflows/release-artifacts.yml`:
|
||||
|
||||
- `linux-x64` (`linux/amd64`)
|
||||
- `linux-arm64` (`linux/arm64`)
|
||||
- `macos-arm64` (`darwin/arm64`)
|
||||
- `macos-x64` (`darwin/amd64`)
|
||||
- `windows-x64` (`windows/amd64`)
|
||||
|
||||
The shell installer and npm wrapper resolve the applicable artifacts from that
|
||||
list. The PowerShell installer supports the published `windows-x64` artifact;
|
||||
there is no native Windows ARM64 artifact. Windows on ARM users can run the x64
|
||||
build under emulation or build from source.
|
||||
|
||||
Android/Termux is also supported even though it has no distinct release
|
||||
artifact. The npm wrapper maps Android to the Linux artifact, and
|
||||
`docs/INSTALL.md` documents the native `android/arm64` source build needed on
|
||||
devices whose seccomp policy blocks the Linux build's syscall path.
|
||||
|
||||
Other `GOOS`/`GOARCH` values, including Plan 9, are unsupported. They are not a
|
||||
review criterion. Do not block a pull request for failing to compile on an
|
||||
unsupported target. Tests may use `plan9` as a fixture for an unsupported OS.

Zero includes local file/search/edit/shell tools, `web_fetch` for public URLs,

|

|

`web_fetch` refuses loopback, private and other special-use addresses: it checks

the URL before asking permission, resolves the host, and dials the address it
|

validated so a name cannot resolve to something else in between.

If `HTTP_PROXY`/`HTTPS_PROXY` is set, `web_fetch` and the provider connectivity

reaches. The URL is still checked and resolved locally first, but a proxy that

### Code Quality and Security Checks
|
||||
|
||||
Before committing any changes, ensure all Go code quality and security checks pass. The `make` targets below pin each tool to this module's Go version, so they load correctly even when your default `go` toolchain is older — running the plain `go run ...@version` form yourself can select the tool module's own (older) toolchain and fail to load this module instead.
|
||||
Before committing any changes, ensure all Go code quality and security checks pass. Pinned `go run` commands matching CI constraints can be used directly without prior installation:
|
||||
|
||||
1. **Formatting**: Run `make fmt` (or `go fmt ./...`).
|
||||
2. **Vetting**: Run `make vet` (or `go vet ./...`).
|
||||
3. **Linting**: Run `make lint-static`.
|
||||
4. **Vulnerability Scan**: Run `make vulncheck`.
|
||||
1. **Formatting**: Run `go fmt ./...` (or `make fmt`).
|
||||
2. **Vetting**: Run `go vet ./...` (or `make vet`).
|
||||
3. **Linting**: Run `go run github.com/golangci/golangci-lint/v2/cmd/[email protected] run --enable-only unused,ineffassign,staticcheck ./...`.
|
||||
4. **Vulnerability Scan**: Run `go run golang.org/x/vuln/cmd/[email protected] ./...`.
|
||||
|
||||
Use the repository-managed targets rather than globally installed binaries:
|
||||
the targets apply the module's required Go toolchain as well as the reviewed,
|
||||
pinned tool versions.
|
||||
|
||||
The installed binaries land in `$GOBIN` when it is set, otherwise in
|
||||
`$GOPATH/bin` (default `~/go/bin`). That directory must be on your `PATH` to
|
||||
run them directly. If it isn't, add it:

- **保持控制权。** 文件写入、Shell 命令、网络访问和工作区外写入都经过 Zero 的权限和沙箱策略。
|
||||
- **在终端中工作。** TUI 具有模型/提供商选择器、图片输入、斜杠命令、实时计划/工具渲染、回滚滚动、主题以及恢复/分叉支持。
|
||||
- **无 TUI 也能工作。** `zero exec` 可脚本化，支持文本/JSON/stream-JSON I/O、隔离的工作树、规范优先运行，以及用于 CI 的有意义的退出码。

blessed one.

|
||||
|
||||
`zero upgrade` follows whatever owns the binary, with one exception it cannot
|
||||
detect. It delegates to npm for an npm install, refuses outright for a Homebrew
|
||||
keg and names `brew upgrade zero`, and replaces the binary in place for
|
||||
everything else — including a mise-managed one, which is the exception.
|
||||
|
||||
mise is the one case it cannot detect: a mise-managed binary is an ordinary
|
||||
standalone install on disk, so `zero upgrade` will replace it and leave mise
|
||||
describing a version that is no longer there. Use `mise upgrade` instead.
|
||||
|
||||
Release archives are the substrate for most of the above: the install scripts
|
||||
and the npm fallback both download a platform archive from a published GitHub
|
||||
Release and verify its checksum.
|
||||
The install scripts download a platform-specific release archive and require a
|
||||
published GitHub Release for the requested version. The npm package is
|
||||
self-contained: the platform binary installs from the npm registry.

[mise](https://mise.jdx.dev/) installs Zero straight from the GitHub Release

Updates come from `mise upgrade`. `zero upgrade` also works, because a

release archives. Two consequences worth knowing before you pick it:

|

- On Linux you also need the sandbox helper, which is a separate binary and is

not installed by this command. See
|

[Sandbox Helpers For Source Builds](#sandbox-helpers-for-source-builds).
|
||||
Without it, native sandboxing is unavailable.
|
||||
- `zero upgrade` treats the result as a standalone install and will replace the
|

binary with a release build rather than rebuilding from source. If you chose

`go install` deliberately, rerun it instead.

`zero upgrade` behaves differently depending on how Zero was installed, because

overwriting a binary a package manager owns leaves that manager describing a

version that is no longer there:
|

|
||||
- **npm**: runs `npm install -g @gitlawb/zero@latest` for you.
|
||||
- **Homebrew**: refuses, and tells you to run `brew upgrade zero`. Replacing the
|
||||
keg binary directly would be reverted by the next `brew upgrade` or

||||
`brew reinstall`.
|
||||
- **everything else**: downloads the verified release archive and replaces the

Homebrew is detected by the binary living inside a Cellar keg that carries

Homebrew's own `INSTALL_RECEIPT.json`. The keg shape alone is not enough: a

directory tree you built yourself can have exactly that shape, and refusing to

update an install Homebrew never touched would be a real cost for a made-up

reason. The receipt is the thing only Homebrew writes.

`TaskStop` to a stale PID that may now belong to an unrelated process.
|
||||
|
||||
## Recovering an Interrupted Overwrite
|
||||
|
||||
Zero writes and flushes a complete temporary file before publishing an overwrite,
|
||||
so a write failure before publication leaves the existing manifest unchanged
|
||||
instead of truncating it. On Unix, publication uses a same-directory rename and
|
||||
preserves the existing file's permission bits.
|
||||
|
||||
On Windows, Zero uses `ReplaceFileW` to preserve the destination DACL instead of
|
||||
silently replacing it with the temporary file's inherited DACL. `ReplaceFileW`
|
||||
is not observer-atomic: another process can briefly observe the destination path
|
||||
as absent during replacement. Zero serializes specialist loads and managed
|
||||
mutations within one process, but cannot synchronize external processes or
|
||||
editors.
|
||||
|
||||
Windows errors 1176 (`ERROR_UNABLE_TO_MOVE_REPLACEMENT`) and 1177
|
||||
(`ERROR_UNABLE_TO_MOVE_REPLACEMENT_2`) are partial replacement failures. With
|
||||
Zero's managed backup, 1176 leaves the original names intact and needs no manual
|
||||
recovery. For 1177, Zero has moved the original aside and tries to move it back.
|
||||
That rollback almost always succeeds, and the failed write changes nothing.
|
||||
|
||||
If the rollback itself fails — typically because another process is holding a
|
||||
lock on the file — the original is not lost, but it is left under a name Zero
|
||||
does not read:
|
||||
|
||||
```text
|
||||
<specialist dir>/.zero-replace-<random>.backup
|
||||
```
|
||||
|
||||
Only `*.md` files are loaded as specialists, so until that file is renamed the
|
||||
specialist will not appear in `zero specialist list` or resolve by name. Zero's
|
||||
error message includes both the backup path and destination path. Recover by
|
||||
closing whatever holds the lock and renaming the backup back:
|
||||
|
||||
```powershell
|
||||
Move-Item .zero-replace-<random>.backup <name>.md
|
||||
```
|
||||
|
||||
A `.zero-replace-*.backup` can also linger after a *successful* overwrite if the
|
||||
backup could not be deleted afterward. That case is reported as a warning rather
|
||||
than an error — the new manifest is already in place, and the leftover file is
|
||||
safe to delete.

## Windows recovery state (standalone installs)
|
||||
|
||||
This section describes Windows only. On Linux and macOS a standalone update
|
||||
renames the staged file directly over the executable path through the
|
||||
installation directory's file descriptor, so the replacement is atomic and no
|
||||
aside copy, marker, or recovery record is ever created — a failed update leaves
|
||||
the previous binary in place and nothing to resolve.
|
||||
|
||||
On Windows, a running executable cannot be replaced in place, so the previous
|
||||
binary is moved aside to `<binary>.zero-update-<random>.old` first. The updater
|
||||
records that exact file — bound to its filesystem identity, in per-user state
|
||||
outside the installation directory — and deletes only that recorded copy after
|
||||
the next update is verified in place. Backups it did not create are never
|
||||
removed, so a file such as `zero.exe.before-manual-patch.old` is left alone. A
|
||||
recorded copy that something else holds open (an on-access scanner, an editor)
|
||||
stays recorded and is removed by a later update instead.
|
||||
|
||||
An update **refuses to run** while unresolved recovery state exists beside the
|
||||
binary:
|
||||
|
||||
| State on disk | Meaning |
|
||||
|---|---|
|
||||
| `<binary>.old` (or `<binary>.<suffix>.old`) plus a `.keep` marker, or a per-user update-recovery record naming that copy | A previous update could not restore the original binary. The `.old` file may be the last binary the updater verified; the installed one may be unverified. The `.keep` marker is in the installation directory and can be deleted; the identity-bound record is not, so deleting the marker alone does not end the refusal. |
|
||||
| `<binary>.…old.<suffix>.recovery` | A previous update could not even write the marker, so it moved the last verified binary to that name. |
|
||||
| The binary is missing and one or more `*.old` files exist | The previous attempt was interrupted between moves. |
|
||||
|
||||
The refusal names the paths involved and the two moves that end the state:
|
||||
either move the recovery binary back over the executable path, or — if the
|
||||
installed binary is the one you want — delete the recovery copy itself (not
|
||||
only the `.keep` marker) after verifying the installed binary, then update
|
||||
again. Deleting the marker alone is not enough: a failed restore also records
|
||||
that copy in per-user state outside the installation directory, and the next
|
||||
update consults that record even if the marker is gone.
|
||||
|
||||
That trusted record lives under `%AppData%\zero\update-recovery` (per-user).
|
||||
The recovery copy and its `.keep` marker sit in the installation directory
|
||||
(per-machine). A second Windows account on the same machine does not see the
|
||||
first account's unresolved record; the sibling marker is the machine-visible
|
||||
signal for every account. There is no separate machine-wide store: writing one
|
||||
would need a shared writable location and ACL rules the updater does not own.
|
||||
|
||||
This is deliberately fail-closed and differs from older releases, which deleted
|
||||
`<binary>.old` and proceeded. The trade-off is that anyone who can write in the
|
||||
installation directory can plant `<binary>.old` and `<binary>.old.keep` there
|
||||
and make every subsequent update refuse until an operator clears them. That is
|
||||
the safe direction: the alternative is an update that overwrites the only
|
||||
verified copy of the previous binary. If updates start refusing, inspect those
|
||||
files before removing them — an installation directory that a lower-privileged
|
||||
account can write to is itself worth fixing.
|
||||
verify its `.sha256` file. If Zero is already installed, run `zero update --check`
|
||||
before reinstalling.

## Editing discipline
|
||||
|
||||
- Choose the narrowest tool that safely accomplishes the step. Prefer native
|
||||
file tools - read_file, read_minified_file, list_directory, glob, grep,
|
||||
edit_file, apply_patch, write_file - over shelling out to
|
||||
cat/sed/awk/python for file operations.

file tools - read_file, list_directory, glob, grep, write_file, edit_file,
|
||||
apply_patch - over shelling out to cat/sed/awk/python for file operations.
|
||||
They are safer, reviewable, and produce clean diffs.
|
||||
- Use read_minified_file only to explore large or unfamiliar source. Use
|
||||
read_file for small or likely edit targets and exact text, comments, or line
|
||||
numbers. Do not read both unless a new need for exact content appears.
|
||||
- Keep edits focused and reviewable. A single patch may update several related
|
||||
files when they form one coherent change; do not hide unrelated edits in a
|
||||
bulk shell or script rewrite.
|
||||
- For edits to existing files, use edit_file for a targeted change (old_string
|
||||
must match the file exactly and be unique, so include a few surrounding
|
||||
lines) and apply_patch when one coherent change spans several hunks or
|
||||
files. Use write_file only to create a file or when most of it changes; do
|
||||
not rewrite a whole file to change a few lines. Match the existing
|
||||
indentation, imports, and idioms. Match the file's comment density: do not
|
||||
add explanatory comments unless the user asks or the code is already
|
||||
comment-dense.
|
||||
- A successful edit result already confirms the change; do not re-read a file
|
||||
just to verify an edit that succeeded. If an edit fails, read the error, fix
|
||||
the old_string or hunk, and retry the same tool rather than switching to a
|
||||
full rewrite.
|
||||
- Make one tool call per file. Do not batch multi-file writes into a single
|
||||
shell or script invocation.
|
||||
- For edits to existing files, prefer edit_file or apply_patch with minimal,
|
||||
targeted diffs. Match the existing indentation, imports, and idioms. Match the
|
||||
file's comment density: do not add explanatory comments unless the user asks or
|
||||
the code is already comment-dense.
|
||||
- Solve the problem as posed, not a more general version of it. Add no
|
||||
speculative abstraction, configurability, or handling for cases that cannot
|
||||
occur, and nothing the user did not ask for. A small diff can still be
|
||||
over-built; if a 200-line solution could be 50, rewrite it. Once the required
|
||||
behavior passes validation, stop instead of adding optional cleanup.
|
||||
over-built; if a 200-line solution could be 50, rewrite it.

- Preserve behavior you were not asked to change. Do not delete or rewrite code
|

you did not author unless the task requires it; if you must, say so.
|
||||
|
||||
## Testing gate (mandatory)
|
||||
|
||||
- After code changes, run the project's documented appropriate validators.
|
||||
Scope iteration checks, combine compatible commands when diagnostics stay
|
||||
useful, and run the final set once after the last edit. Rerun only after a
|
||||
change or failure.
|
||||
- If unsure which entry points apply, inspect the Makefile, manifests, or CI;
|
||||
do not invent a parallel flow.
|
||||
- After any change to code, verify after edits by running the project's
|
||||
validators before you summarize or commit: tests, type-checks, linters, and/or
|
||||
the build, as appropriate. Scope them to the change while iterating; reserve
|
||||
full-suite runs for milestones.
|
||||
- If you are unsure which validators apply, search the repo (Makefile, package
|
||||
manifests, CI config) to find them.
|
||||
- Never claim a task is done, and never commit, while validators are failing. If
|
||||
they fail, fix the cause and rerun; do not paper over it. If you could not run
|
||||
a validator, say so explicitly rather than implying success.
|
||||
- A successful native patch confirms the edit. Reread only when the next change
|
||||
needs exact content or the result was ambiguous.
