Session 0056.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-26T04-24 (PST) End: 2026-06-26T04-54 (PST) Type: planning-and-executing Posture: autonomous (yolo) Status: FINALIZED

Launch prompt

/wgl-planning-and-executing implement #60 (live turn progress) from coauthoring-live-progress.md

(Continuation of brainstorming session 0055, which graduated the spec; the operator said "implement it" → this coding session.)

Plan

Plan + execute #60 (P1 feature — live turn progress) from the graduated Solution Design coauthoring-live-progress.md. Four cuts: (1) pure turnProgress.ts reducer + tests; (2) runEditTurn + onProgress/AbortSignal; (3) liveProgressUi + setting + both call sites; (4) host-E2E + smoke. Branch s60-live-progress → PR → main.

Pre-state

• Clean main at session start (fast-forwarded 13 commits — the sessions/ repo is the code repo itself). Baseline: 222 unit green.
• #60 has a graduated Solution Design → §4.3 R2(b) satisfied.

Session arc

1. Claim + plan. Claimed 0056 (no in-flight). Wrote the implementation plan with superpowers:writing-plans → docs/superpowers/plans/2026-06-26-live-turn-progress.md (self-reviewed: full spec coverage, no placeholders). Grounded in the exact SDK types (AgentToolCallPart.toolName, AgentUsage.inputTokens+outputTokens), the vitest/host-E2E patterns, and the injectable editTurn seam. Branch s60-live-progress.
2. Task 1 — pure reducer. src/turnProgress.ts + test/turnProgress.test.ts (13 cases). Fixed the type-only event import: AgentRuntimeEvent is exported from @cline/shared, not @cline/sdk (which doesn't re-export it) — caught by typecheck; amended the commit.
3. Task 2 — runEditTurn. Added RunEditTurnOptions {onProgress, signal}; subscribes to the agent, folds events through the reducer, wires signal → agent.abort(); finally unsubscribes. Mocked-agent unit tests (vitest doMock intercepts the dynamic import).
4. Task 3 — host relay. src/liveProgressUi.ts (notification line + "Cowriting: Claude" OutputChannel, reveal gated by setting) + package.json contributes.configuration cowriting.liveProgress.revealOutput.
5. Tasks 4+5 — both call sites. editSelection (extension.ts) and preview askClaude/runEditAndPropose (trackChangesPreview.ts) made cancellable, relaying via the shared liveProgressUi; widened the EditTurn seam to accept opts? (back-compat). Added liveProgressUi to CowritingApi.
6. Task 6 — host E2E. test/e2e/suite/liveProgress.test.ts: progress is additive (INV-44), aborted turn proposes nothing (INV-47).
7. Task 7 — verify + smoke. typecheck + 237 unit + build green; enhanced scripts/smoke-live-turn.mjs to log progress.
8. Subagent review. Found a Medium (a pre-aborted AbortSignal was a no-op — agent.abort() runs before the SDK's AbortController exists, so the turn ran to completion) + a Low (a throwing onProgress relay could fail the turn). Fixed both: short-circuit (throw) before run() on a pre-aborted signal; wrap the relay in try/catch. Strengthened the unit + E2E to prove it.
9. Ship. Pushed; opened PR #61; operator approved merge despite the concurrency (below). Squash-merged 644885c; issue #60 auto-closed.

⚠️ Concurrency event (mid-session)

Partway through, the shared working tree gained uncommitted changes this session did NOT make — a cowriting.edit / routeEdit reach refactor across src/workspacePath.ts, test/workspacePath.test.ts, and the menu/routeEdit parts of package.json + src/extension.ts. It broke 3 E2E (f12Reach ×2, f11Toolbar ×1) that still expect the old editSelection/editDocument command surface. Handling: committed nothing of it, discarded nothing; verified #60 green in isolation by stashing it (by path, reversible) — 237 unit + both #60 E2E pass, only the documented F10 #38 undo-sandbox flake remains — then popped the stash to restore it. Surfaced to the operator, who chose to merge #60 (its 7 commits are isolated; the PR diff contains none of the foreign WIP).

Cut state (at finalize)

• #60 merged to main (PR #61 squash 644885c); issue #60 closed.
• Plan archived: submit-plan.sh → content repo plans/2026-06-26-live-turn-progress.md (22ec57e).
• Foreign refactor WIP: still uncommitted in the working tree, untouched — for whoever is doing it to continue/commit (it rebases onto the new main).
• Local tree: left on branch s60-live-progress (merged) DELIBERATELY — a checkout main/pull would have disturbed the foreign uncommitted WIP. Local main not synced; origin/main has #60. Operator should reconcile the local tree
  • the in-flight refactor.
• Memory: added session-0056-60-live-progress-shipped.md + index line.

Next-session prompt

/wgl-planning-and-executing reconcile the local tree (sync main; land/branch the in-flight cowriting.edit/routeEdit refactor), then pick the next item (open: #59 P1 bug, #57, #58, #32, #35, #40, OQ-2)

Deferred decisions

• Left local on s60-live-progress (did not sync main): to avoid disturbing the concurrent uncommitted refactor in the shared tree. Low confidence this is the tidiest end state, but it is the safest for the foreign WIP. Operator to reconcile.
• Token field for the activity line: used inputTokens + outputTokens from AgentUsage (no totalTokens field exists). Cache tokens excluded.
• OutputChannel append-not-clear + auto-reveal gating: per spec §3.5; carried from session 0055's confirmed sub-decisions.
