# Phase 1 Cross-Compat Test Skill Verifies that harness-maker's `.claude/skills/<name>/SKILL.md` is recognized by both Claude Code and Cursor 2.4+ (which adopted the Anthropic SKILL.md standard). ## Mission When this skill is invoked, output exactly this single line and stop: ``` PHASE-1 A3 PASSED — skill loaded from .claude/skills/test-skill/ in <IDE-name> ``` Replace `<IDE-name>` with the current IDE. No additional work. No tool calls. ## Frontmatter cross-compat checkpoints - `name` (required) — kebab-case identifier - `description` (required) — one-sentence summary used for auto-dispatch - `when_to_use` — Anthropic standard trigger condition - `user-invocable: true` — Anthropic standard, exposes the skill as a slash command If both IDEs accept all four keys without strict-rejection AND auto-discovery fires on the trigger phrase, A3 passes.
