Skill Creator (harness projects)

Create and improve project-local skills in the active harness project. The eval loop, description optimization, and bundled scripts come from the upstream skill-creator (anthropics/skills) — this skill only overrides where files are saved and runs harness sync after each create/update.

Harness discovery

Resolve paths per ../nextstage-harness/references/harness-discovery.md:

Variable	Value
`{product_root}`	Repo or monorepo product folder (where `AGENTS.md` lives)
`{skills_canonical}`	`{product_root}/.agents/skills/`

If {harness_root} is missing, tell the user to run npx @nextstage-brasil/harness first — this skill expects a harness-scaffolded project.

Step 0 — Load upstream skill-creator

Harness init installs the anthropics skill-creator bundle (scripts, eval-viewer) at {skills_canonical}/skill-creator/, then overlays this wrapper as SKILL.md.
