## Launch prompt

`/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`.
8. **Finalize.** Base survey clean (all work already landed). Planning-and-
   executing addendum: archiving the plan surfaced that
   `vscode-cowriting-plugin-content` was **empty on the remote** (session 0001
   committed its draft issues locally but never pushed). Asked the operator how
   to initialize → "publish drafts + plan": pushed the content repo's local
   `main` (publishing the two draft issue files, `01b593c`), then archived the
   POC plan under `plans/` via `submit-plan.sh` (`a77704e`).

## Cut state

- **Code repo** `vscode-cowriting-plugin`: `main` at `cff62f5` (merge of PR #3),
  + transcript checkpoint `27eb335`; clean and pushed. POC builds + tests green.
- **Content repo** `vscode-cowriting-plugin-content`: initialized on the remote;
  `main` at `a77704e` — `issues/` (2 draft files from 0001) +
  `plans/2026-06-09-poc-cline-sdk-extension.md`.
- **§9 pipeline:** N/A — a non-shippable VS Code *extension*, no deployable
  webapp, so no localhost-E2E / PPE / prod stage or flotilla deploy. "Complete"
  = merged + build/test green + plan archived.
- **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`. The only unverified acceptance criterion.

## Operator plate

- **Press F5** to confirm the POC's GUI acceptance criterion (above).
- **Repo visibility:** both `vscode-cowriting-plugin` and `-content` are
  **public** on Gitea (carried over from session 0001) — confirm if unintended.

## Next-session prompt

```
/goal Build the next coauthoring feature on the POC skeleton — the next Feature in epic #1's decomposition (F2+ from ben.stull/rfc-app#48: threads, attribution, git-native persistence) — driving a real @cline/sdk agent run (provider/auth wiring) rather than the pure catalog call. Confirm the exact next Feature against the tracker first.
```

## Deferred decisions

- **Content repo initialization (resolved by operator).** Archiving the plan
  required initializing the empty `-content` remote, which was entangled with
  session 0001's deferred "publish or discard the draft issues" decision. Rather
  than default it autonomously (it reached into another session's Author
  gesture), asked the operator → chose **publish drafts + plan**. No other
  low-confidence autonomous calls this session.
