Error message

expected one match for {pattern!r} in {path}

What it means

SystemExit raised by replace_unique() in the bump-version recipe when re.subn finds zero occurrences of '^version\s*=\s*"[^"]+"' in one of the listed crate Cargo.toml files (count is capped at 1, so 'not 1' means 'not found'). The recipe demands exactly one literal version line per crate so it cannot silently skip or double-edit a manifest.

Solutions

1. Grep the failing crate's manifest for the version line: rg '^version' crates/<name>/Cargo.toml — the failing path is printed in the error
2. If it uses version.workspace = true, give it a literal version = "x.y.z" line (or drop it from crate_names)
3. Run the recipe from crates/goose-sdk so the relative crates/<name>/Cargo.toml paths resolve
4. Keep the crate_names list in the justfile in sync with reality when crates are added/renamed

Example fix

# before (crates/goose-sdk/Cargo.toml)
[package]
name = "goose-sdk"
version.workspace = true

# after
[package]
name = "goose-sdk"
version = "0.1.0"

    assert p.is_file(), f"missing {p}"

When it happens

Trigger: Running 'just bump-version <version>' when a crate in crate_names (goose-provider-types, goose-sdk-types, goose-download-manager, goose-local-inference, goose-providers, goose-agent, goose-context-management, goose-sdk) has no literal 'version = "..."' line — typically because its Cargo.toml uses 'version.workspace = true', the file was renamed/removed, or the recipe is run from a directory where crates/<name>/Cargo.toml does not resolve.

Common situations: A crate was switched to workspace-inherited versions; a new crate was added to the workspace but not given its own version line; running the recipe outside crates/goose-sdk so relative paths miss; a crate listed in the recipe was deleted/renamed.
