Session 0002.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-09T23-44 (PST) End: 2026-06-10T00-13 (PST) Type: planning-and-executing Status: FINALIZED

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.
