description	Improve an existing episode's script by diagnosing engagement gaps (curiosity / expectation / drop-off zones via the E0–E3 lens) and producing an improved version. Auto-detects the original episode's genre (yadam / dark-history / bespoke) and reuses its meta-prompts. Forks the original to {ep}-v2 — original preserved. Re-runs only the affected wave scope (polish / restructure / full). Trigger: 'improve script', 'fix draft', 'rewrite my episode', 'improve ep03', '대본 개선', '다시 써줘', 'ep03 개선'.
argument-hint	[episode-number-or-path] [--scope polish|restructure|full]

Improve an existing episode's script. Diagnose engagement gaps using the engagement principle (curiosity + expectation = 몰입도; see story-engine SKILL.md 핵심 원칙), present a fix plan to the user, and produce an improved version forked from the original.

Reuses:

• The original episode's genre (auto-detected from STATE.md)
• The genre's meta-prompts (yadam / dark-history / bespoke)
• W2/W3/W4–W9 waves (re-runs only the affected scope, not the whole pipeline)

Creates:

• {ep}-v2/ directory (original {ep}/ preserved — no overwrite)
• _story_source/01_improvement_diagnosis.md — engagement gap analysis
• New synopsis/script for the chosen scope
• Updated downstream artifacts (only for changed scenes/parts to save cost)

After this command: Pauses for user-confirmed scope, then chains into the chosen wave subset (typically /story-execute --from W{N}).

$ARGUMENTS

Inputs accepted:

• Episode number (e.g., "ep03") — auto-locates the dir under PROJECT_DIR
• File path to a draft markdown — uses as-is; asks for genre + ep number

Optional --scope flag:

• polish — prose-level rewrites for drop-off zones; structure preserved
• restructure — rebuild a specific act (synopsis + script for that act)
• full — full rewrite (use draft as topic; effectively /story-new on same topic)

If --scope is omitted, the workflow runs diagnosis and asks the user.

Genre auto-detection: reads STATE.md of the source episode. If unavailable, asks via AskUserQuestion.

Distinction from existing W1 [Rewrite] path: the W1 [Rewrite] path (in docs/{lang}/W1-story-design.md) analyzes someone else's successful reference to learn its patterns and produce a NEW script. This skill analyzes YOUR OWN draft to find engagement weaknesses and produce an IMPROVED version. Different operations.
