 - **하지 않기로 한 것** — **MCP 서버**(의도적으로 폐기: 셸이 있는 에이전트에는 `--json` + skill이 세션당 컨텍스트 비용 없이 더 나은 계약이며, 여기엔 빠른 구조화 질의가 없음). repo별 **scene 설정** 제거(어떤 화면이 *당신의* money shot인지는 환원 불가한 의도 — `shotkit.config.js`에 둠). 범용 동영상 편집기(v1은 깔끔한 녹화만; 편집은 계획). 호스티드 서비스(파일을 만지는 캡처는 본질적으로 로컬).

 ## Status & Scope
 
-- **Currently implemented** — A Playwright capture **engine** (build → launch the *built* extension via `launchPersistentContext(--load-extension)` → drive scenes → screenshot → caption/disclaimer band → promo tile from HTML → demo `webm` → listing copy from `STORE_LISTING.md`), a **CLI** (`shotkit`) with an **agent contract** (`--json` machine output, optional `path` argument, `0/1/2` exit codes), **size presets** for both audiences (CWS `1280×800`/`440×280`, SNS `1200×675`/`1200×630`/`1080×1080`), a **path-traversal-safe** localhost fixture server, a programmatic API (`capture()`), a **Claude Code skill** ([`skills/capture/`](skills/capture/SKILL.md)), an **AGENTS.md run-block** so any shell-having coding agent can invoke it, and the **npm package** [`@starter-series/shotkit`](https://www.npmjs.com/package/@starter-series/shotkit). Consumed by `browser-extension-starter` and `skillBridge`.
-- **Planned** — a listing in the `starter-series` plugin **marketplace**; **video editing** (`webm → mp4`, trim, captions) for SNS.

+- **Planned** — **video editing** (`webm → mp4`, trim, captions) for SNS.
 - **Design intent** — *One engine, many surfaces — matched to the tool's nature.* shotkit is a heavy, file-producing build tool, so its surfaces are CLI (+`--json`), skill, and CI — not MCP (see Non-goals). Captures are **deterministic** (login-free fixtures, frozen data) and the run **doubles as a real-bundle smoke test** — a screenshot only appears if that feature rendered from the shipped code. **Trademark-safe** by construction: a disclaimer band is composited onto every shot.
 - **Non-goals** — An **MCP server** (dropped by design: agents with a shell get a better contract from `--json` + the skill, without MCP's per-session context cost; nothing here is a fast structured query). Removing the per-repo **scene config** (which screens are *your* money shots is irreducible intent — it lives in your `shotkit.config.js`). A general-purpose video editor (v1 records a clean screencast; editing is Planned). A hosted service (file-touching capture is local by nature).
 - **Redacted** — none. Ships no private data, credentials, or third-party identifiers.
