Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughAntigravity CLI resolution now runs in a dedicated module. It validates configured paths and searches ordered candidates when no override is set. Provider fallback paths use the resolver, and tests cover resolution errors and fallback behavior.

- Line 24: Update the ANTIGRAVITY_CLI_PATH override handling at the
path.is_file() check to resolve a valid relative path to an absolute path before
returning it, while preserving the existing error handling for paths that cannot
be resolved.
- Line 44: Update the fixed-path candidate filtering in discover so a file is
accepted only after a local runnable-path preflight: check execute permission on
Unix and reject .ps1 and .vbs extensions case-insensitively on Windows. Keep the
existing PATH lookup behavior and fail-closed handling for invalid configured
overrides; treat the preflight only as a filter, not a guarantee that launch
will succeed.

<excerpt>Constructs a new `Command` for launching the program at path `program`, with the following default configuration: ... If `program` is not an absolute path, the `PATH` environment variable will be searched in an OS-defined way. ... ##### § Platform-specific behavior ... The details below describe the current behavior, but these details may change in future versions of Rust. ... On Unix, the `PATH` searched comes from the child’s environment: ... - If the environment is unmodified, the child inherits the parent’s `PATH` and that is what is searched. - If `PATH` is explicitly set via `env`, that new value is searched. - If `env_clear` or `env_remove` removes `PATH` without a replacement, `execvp` falls back to an OS-defined default (typically `/bin:/usr/bin`), not the parent’s `PATH`. This may fail to find programs that rely on the parent’s `PATH`. ... To avoid surprises, use an absolute path or explicitly set `PATH` on the `Command` when modifying the child’s environment. ... On Windows, Rust resolves the executable path before spawning, rather than passing the name to `CreateProcessW` for resolution. When `program` is not an absolute path, the following locations are searched in order: ... 1. The child’s `PATH`, if explicitly set via `env`. 2. The directory of the current executable. 3. The system directory (`GetSystemDirectoryW`). 4. The Windows directory (`GetWindowsDirectoryW`). 5. The parent process’s `PATH`. ... Note: when `PATH` is cleared via `env_clear` or `env_remove` on Windows, step 1 is skipped but the parent process’s `PATH` is still searched at step 5, unlike on Unix. ... `Command::new` ... only intended to accept the path of the program ... Command::new("ls -l ... 1.0.0 · Source pub fn current_dir >(&mut self, dir: P) -> &mut Command ... Sets the working directory for the child process. ... ##### § Platform-specific behavior ... If the program path is relative (e.g., `"./script.sh"`), it’s ambiguous whether it should be interpreted relative to the parent’s working directory or relative to `current_dir`. The behavior in this case is platform specific and unstable, and it’s recommended to use `canonicalize` to get an absolute program path instead. ... ##### § Examples ... ``` use std::process::Command; Command::new("ls") .current_dir("/bin") .spawn() .expect("ls command failed to start"); ``` ... 1.57.0 · Source pub fn get_current_dir(&self) -> Option<& Path> ...

Resolve a configured relative path before returning it.
If ANTIGRAVITY_CLI_PATH is a bare filename in the current directory, is_file() accepts that file, but the structured fallback launches it with a private working directory. The managed Windows launcher also passes the relative name to CreateProcessW with a separate cwd. Relative executable lookup is platform-specific, so launch can resolve a different agy from PATH or fail. Convert the override to an absolute path before returning it.

<excerpt>which 7.0.0 - Docs.rs # which 7.0.0 A Rust equivalent of Unix command "which". Locate installed executable in cross platforms. # which A Rust equivalent of Unix command "which". Locate installed executable in cross platforms. ## Support platforms - Linux - Windows - macOS - wasm32-wasi* ### A note on WebAssembly This project aims to support WebAssembly with the wasi extension. This extension is a requirement.`which` is a library for exploring a filesystem, and WebAssembly without wasi does not have a filesystem.`which` cannot do anything useful without this extension. Issues and PRs relating to`wasm32-unknown-unknown` and`wasm64-unknown-unknown` will not be resolved or merged. All`wasm32-wasi*` targets are officially supported. If you need to add a conditional dependency on`which` for this reason please refer to the relevant cargo documentation for platform specific dependencies. Here&`#39`;s an example of how to conditionally add`which`. You should tweak this to your needs. ``` [target.&`#39`;cfg(not(all(target_family = "wasm", target_os = "unknown")))&`#39`;.dependencies] which = "7.0.0" ``` ## Examples To find which rustc executable binary is using. ``` use which::which; let result = which("rustc").unwrap(); assert_eq!(result, PathBuf::from("/usr/bin/rustc")); ``` After enabling the`regex` feature, find all cargo subcommand executables on the path: ``` use which::which_re; which_re(Regex::new("^cargo-.*").unwrap()).unwrap() .for_each(|pth| println!("{}", pth.to_string_lossy())); ``` ## MSRV This crate currently has an MSRV of Rust 1.70. Increasing the MSRV is considered a breaking change and thus requires a major version bump. We cannot make any guarantees about the MSRV of our dependencies. You may be required to pin one of our dependencies to a lower version in your own Cargo.toml in order to compile with the minimum supported Rust version. Eventually Cargo will handle this automatically. See rust-lang/cargo#9930 for more. ## Documentation The documentation is available online.</excerpt>

Noop : A handler for non-fatal errors which does nothing with them. Path : An owned, immutable wrapper around a `PathBuf` containing the path of an executable. Which Config : A wrapper containing all functionality in this crate. ## Enums§ Error NonFatal Error ## Traits§ NonFatal Error Handler : Defines what should happen when a nonfatal error is encountered. A nonfatal error may represent a problem, but it doesn’t necessarily require `which` to stop its search. ## Functions§ which : Find an executable binary’s path by name. which_ all : Find all binaries with `binary_name` using `cwd` to resolve relative paths. which_ all_ global : Find all binaries with `binary_name` ignoring `cwd`. which_ global : Find an executable binary’s path by name, ignoring `cwd`. which_ in : Find `binary_name` in the path list `paths`, using `cwd` to resolve relative paths. which_ in_ all : Find all binaries with `binary_name` in the path list `paths`, using `cwd` to resolve relative paths. which_ in_ global : Find all binaries with `binary_name` in the path list `paths`, ignoring `cwd`. which_ re : Find all binaries matching a regular expression in a the system PATH. which_ re_ in : Find all binaries matching a regular expression in a list of paths. ## Type Aliases§ Result</excerpt>

Filter non-runnable fixed-path candidates.
which::which("agy") already returns an executable PATH result. The later %LOCALAPPDATA%/agy/bin/agy.exe and ~/.local/bin/agy candidates use only is_file(), so a stale or non-runnable file can block a later working candidate. Add a local preflight check for these candidates. On Unix, check execute permission. On Windows, reject interpreter-only override extensions such as .ps1 and .vbs case-insensitively because the path is launched directly. Keep invalid configured overrides fail-closed, and do not treat the check as a guarantee that the executable will start successfully.

In `@rust/src/providers/antigravity/cli_resolution.rs` at line 44, Update the
fixed-path candidate filtering in discover so a file is accepted only after a
local runnable-path preflight: check execute permission on Unix and reject .ps1
and .vbs extensions case-insensitively on Windows. Keep the existing PATH lookup
behavior and fail-closed handling for invalid configured overrides; treat the
preflight only as a filter, not a guarantee that launch will succeed.
After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Summary
Ports upstream CodexBar v0.65.0 commit 0b26a89 to Windows. A successful desktop probe remains authoritative. If CLI discovery is needed, an unusable explicit ANTIGRAVITY_CLI_PATH now fails closed instead of falling through to PATH or installed locations; leaving the variable unset preserves automatic discovery. Existing offline/history fallback remains available.
This prevents a background refresh from discovering and launching a different agy binary that may trigger interactive login.
