Current directory does not appear to be a workspace root…

Error message

Current directory does not appear to be a workspace root. Please run this command from the workspace root.

What it means

Also thrown by `check_workspace_root` (tooling/xtask/src/tasks/gpui.rs:300). A Cargo.toml exists in the current directory, but its contents do not contain a `[workspace]` section, so the directory is not the workspace root the publish pipeline requires. This prevents publishing against a standalone crate manifest by mistake.

Solutions

Run the command from the monorepo root whose Cargo.toml contains [workspace] (usually the git repo root).
If you believe the directory IS the root, check the root Cargo.toml still declares `[workspace]` and restore it if missing.
Confirm with `grep -l '^\[workspace\]' Cargo.toml` in the intended directory before running.

Example fix

# before (crate Cargo.toml, no workspace section)
[package]
name = "gpui"

# after — run from root manifest
[workspace]
members = ["crates/*"]

Defensive patterns

Strategy: validation

Validate before calling

let contents = std::fs::read_to_string("Cargo.toml")?;
assert!(contents.contains("[workspace]"), "current directory is not a workspace root");

Prevention

Verify `[workspace]` is present in Cargo.toml before publishing.
Don't run publish from nested crate directories; always start at the monorepo root.
Keep the [workspace] section intact in root manifest reviews/merges.

When it happens

Trigger: Running the publish xtask from a nested crate whose Cargo.toml has only [package], or from a non-workspace Cargo project; a root manifest where the [workspace] section was accidentally removed or renamed.

Common situations: Running from a vendored/sub-project directory; publishing a crate extracted from the monorepo; a broken merge that dropped the [workspace] table from the root Cargo.toml.
