 ## Launch prompt

-_(launch prompt not captured at claim time)_
+`/goal scaffold the #2 POC: runnable extension on @cline/sdk`
+
+Resuming session 0001's next-session prompt: build Feature #2 — a standalone VS
+Code extension on `@cline/sdk` that builds, launches in the Extension
+Development Host on F5, and runs one command that drives the SDK and shows a
+result. Non-shippable proof-of-concept skeleton only. Per issues #2 (epic #1)
+and `ben.stull/rfc-app#48`.
+
+## Plan
+
+Plan: `docs/superpowers/plans/2026-06-09-poc-cline-sdk-extension.md` (written
+this session via `superpowers:writing-plans`, executed inline).
+
+**Architecture (de-risked empirically before coding):** CJS VS Code extension,
+esbuild-bundled. `@cline/sdk@0.0.46` is ESM-only (Node ≥22) and uses
+`createRequire(import.meta.url)`, so it **cannot** be bundled into a CJS
+extension (verified: `import.meta.url` → undefined → throw, 11MB bundle fails).
+It is kept external and loaded at runtime via dynamic `import()` from the
+vscode-free `src/cline.ts`; the bundle stays ~3.3kb.
+
+**The "drives the SDK" command:** `cowriting.showClineSdkInfo` calls the pure,
+key-free `getCoreBuiltinToolCatalog()` + `CORE_BUILD_VERSION` and renders the
+SDK version + the 9 builtin tool IDs to a notification and output channel.
+
+## Arc
+
+1. Session gate → planning-and-executing; claimed session 0002 (no concurrency).
+2. Fast-forwarded `main` (adopted session 0001's finalized transcript), wired
+   `CLAUDE.md` org-context import (none existed), confirmed clean baseline.
+3. Read session 0001 transcript + `app.json` for context: Approach A, scope =
+   scaffold + register only, Feature #2 = smallest runnable POC.
+4. **De-risking (empirical):** inspected `@cline/sdk@0.0.46` (alias of
+   `@cline/core`) type surface; smoke-tested in Node (SDK loads,
+   `CORE_BUILD_VERSION=0.0.46`, catalog of 9 tools `{id, description, …}`);
+   proved CJS-bundling fails and external + dynamic `import()` works.
+5. Wrote the plan, then executed it: manifest + tooling, TDD SDK driver,
+   extension entry, esbuild, F5 launch config, README.
+6. Verified: typecheck clean, unit test passes, 3.3kb build, and the CJS bundle
+   loads + `activate()` registers its disposables under a stubbed `vscode`.
+7. Branch → PR #3 → merged to `main`; branch deleted; build+test green on
+   merged `main`.
+
+## Cut state
+
+- `main` at `cff62f5` (merge of PR #3), clean and pushed. POC builds + tests
+  green. Plan archived under `docs/superpowers/plans/`.
+- **Operator step (GUI, can't be automated in-session):** press **F5** → run
+  "Cowriting: Show Cline SDK Info" → expect `Cline SDK 0.0.46 loaded — 9
+  builtin tools`. This is the only unverified acceptance criterion.
