Invalid repository name format

Error message

Invalid repository name format

What it means

get_local_repo_path computes the on-disk clone location for the recipe repo by splitting GOOSE_RECIPE_GITHUB_REPO's value on the first '/' (crates/goose-cli/src/recipes/github_recipe.rs:160-167). split_once returns None when the value contains no slash, and this error replaces it — it is pure input validation on the config value, before any network or git activity.

Solutions

1. Set the variable to the full owner/repo form: export GOOSE_RECIPE_GITHUB_REPO=owner/repo
2. Check the current value: `echo "$GOOSE_RECIPE_GITHUB_REPO"` — empty output means it is unset-but-defaulted or exported blank somewhere (shell profile, .env, CI variables)
3. If you use a URL form, strip it down to owner/repo before setting the variable

Example fix

# before
export GOOSE_RECIPE_GITHUB_REPO=my-recipes

# after
export GOOSE_RECIPE_GITHUB_REPO=block/my-recipes

# Validate the config value before any goose run
repo="${GOOSE_RECIPE_GITHUB_REPO:-}"
case "$repo" in
  */*) : ;;                    # contains a slash: OK for owner/repo
  *) echo "GOOSE_RECIPE_GITHUB_REPO must be owner/repo (got: '$repo')" >&2; exit 2 ;;
esac

// Rust: narrowing guard for the repo full-name format
fn is_valid_repo_full_name(value: &str) -> bool {
    match value.split_once('/') {
        Some((owner, repo)) => !owner.is_empty() && !repo.is_empty() && !repo.contains('/'),
        None => false,
    }
}

When it happens

Trigger: GOOSE_RECIPE_GITHUB_REPO is set to a value without an owner/repo slash: "my-recipes", "", or a full URL like "https://github.com/owner/repo" also fails? — no: a full URL contains '/' and splits (incorrectly) — the direct trigger is any slash-less value. Reachable from clone, fetch, and cleanup paths.

Common situations: Copy/paste of just the repo name instead of owner/repo, an empty env var (GOOSE_RECIPE_GITHUB_REPO="") exported by a script, or whitespace/format drift in .env files.
