Solutions

1. Read the stderr included in the message to see why the claude CLI failed.
2. Verify the claude CLI is installed, on PATH, and authenticated before running improve_description.py.
3. Retry after fixing the reported CLI error (auth, model access, or rate limit).

Example fix

Authenticate the CLI (claude login) and confirm `claude -p "hello"` succeeds, then rerun the script.

When it happens

Trigger: The skill-creator improve_description script shells out to `claude -p` and the CLI exits with a non-zero return code.

Common situations: Occurs when the Claude CLI is missing, unauthenticated, rate-limited, or the prompt run otherwise fails. The RuntimeError includes the exit code and captured stderr; the description improvement run aborts.
