Separate a skill's portable capability knowledge from the Studio-specific tool binding. Skill bodies under skills/<name>/SKILL.md name no tools; the mapping to concrete tools lives in skill-overlays/<name>.md and loadSkills() appends it under an "In Studio" heading. Skills with no overlay load unchanged. This keeps skill bodies liftable into a shared cross-harness skill library (Studio Code/CLI/App/Web, and other agent surfaces) without rewriting, while Studio's tool names stay in Studio. Extracts the layout-verification guidance into a verify-layout skill as the first example, backed by take_screenshot / measure_elements via its overlay.

… loader YAGNI — the loader-based overlay mechanism (and its build wiring) isn't needed to ship a harness-agnostic skill. Keep verify-layout's body tool-free and put the one Studio-specific line in an inline 'In Studio' section, kept separable so the body can move to a shared cross-harness skill later. The mechanical loader/overlay can land then, when there's a second consumer to justify it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Proposed Changes
A deliberately tiny slice: extract the layout-verification guidance into its own
verify-layoutskill whose body is harness-agnostic — it describes the capability (capture a viewport-height slice; measure the rendered DOM) and names no Studio tool. The single Studio-specific line lives in a separate "In Studio" section at the end, kept clearly separable.The point is the shape, not the size: a skill body written this way can later be lifted verbatim into a shared, cross-harness skill library that Studio and Telex both consume, while each keeps its own tool names. This is the smallest version of that idea — a real, mergeable skill, no new machinery.
Intentionally not here (YAGNI): a loader/overlay mechanism that injects the Studio section from a separate file, and the shared package itself. Those are clean follow-ups once there's a second consumer to justify them.
