skill-creator: Create evals workspace outside skill directory to avoid confusion with skills #490
Description
The skill-creator currently creates the evals workspace in the same directory as the skill (under skills/). This layout can be confusing because the evals workspace may look like a separate skill.
Current behavior
- Evals workspace is created at the same level as the skill (inside the skills directory)
Desired behavior
- Evals workspace should be created in a different, dedicated directory (e.g. .agents/evals/, evals-workspace/, or similar), so it is not mixed with skills and not mistaken for a new skill
Rationale
Keeping the evals workspace alongside skills can make it unclear whether it is a skill or evaluation tooling, and may lead to accidental edits or confusion in the skills directory. A separate location would improve clarity and project structure.
