The source uses macOS-only system calls (getattrlistbulk, FSEvents, macOS libc constants) and does not compile on Linux.
Step: cargo build --release (README Quick start)
The source uses macOS-only system calls (getattrlistbulk, FSEvents, macOS libc constants) and does not compile on Linux.
Safety: Review signals: 1 connection review.
Review signals: 1 connection review.
Reviewed as expected for a test run: package managers (rustup-init) downloaded dependencies over HTTPS; resolver address lookups that send no data; wrote only to its own open file handles.
Repository processes attempted these non-loopback connections; proxies can hide the final hostname. 8 distinct locations. 2 attributed processes.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.

]Answers recorded for this run
- fsearch is a whole-disk file search for macOS: The product targets macOS (getattrlistbulk, FSEvents, Apple Silicon release tarball). This Linux guest cannot build it: cargo build --release fails with 48 errors for missing macOS-only libc symbols such as ATTR_DIR_MOUNTSTATUS. No macOS host is available.
Source: Whole-disk file search for macOS: names in about 0.1 ms, typo-tolerant,
Observed: The product targets macOS (getattrlistbulk, FSEvents, Apple Silicon release tarball). This Linux guest cannot build it: cargo build --release fails with 48 errors for missing macOS-only libc symbols such as ATTR_DIR_MOUNTSTATUS. No macOS host is available.
- build from source with cargo, then install: Attempted the README build command on Linux x86_64 with Rust 1.99.1 and cc 13.3. It failed at compile time (exit 101), so ./target/release/fsearch was never produced and install could not run.
Source: cargo build --release && ./target/release/fsearch install # -> ~/.local/bin/fsearch
Observed: Attempted the README build command on Linux x86_64 with Rust 1.99.1 and cc 13.3. It failed at compile time (exit 101), so ./target/release/fsearch was never produced and install could not run.
Examples
- search by name and inside files with the CLI: The fsearch binary cannot be built on Linux (macOS-only APIs), so no CLI query could run. Tests in examples/*.rs need the crate built and were not run.
Source: README.md Quick start / Queries
Expected: documented command completes successfully
Observed: The fsearch binary cannot be built on Linux (macOS-only APIs), so no CLI query could run. Tests in examples/*.rs need the crate built and were not run.
- MCP server for coding agents (fsearch mcp): Requires the built fsearch binary; blocked by the same Linux compile failure.
Source: README.md API
Expected: documented command completes successfully
Observed: Requires the built fsearch binary; blocked by the same Linux compile failure.
Suggested next step (agent-reported): Test on a macOS (Apple Silicon) host, as the README and release workflow (runs-on: macos-15) intend. If Linux support is wanted, gate the macOS-only walk/fsevents code behind cfg(target_os = "macos") and provide a fallback.
What the agent did
Build fsearch from source with the README command and run it (CLI name search, content search, MCP server)
