Session 0055.0 — Transcript

App: vscode-cowriting-plugin Start: 2026-06-22T23-19 (PST) End: 2026-06-26T04-23 (PST) Type: brainstorming Posture: autonomous (yolo) Status: FINALIZED

Launch prompt

/wgl-brainstorming highest priority ticket

Plan

Brainstorming session: explore the highest-priority open ticket and write its Solution-Design spec. Highest-priority that fits a brainstorming session (spec output; a feature needs a design per §4.3 R3) was #60 — Show Claude's live output/progress during the "asking Claude…" status (P1 feature). #59 (P1 bug) is coding-session work, not brainstorming.

Output: specs/coauthoring-live-progress.md (Solution Design), submitted graduated at finalize to the content repo's specs/ collection.

Pre-state

• Clean, pushed main (24e329e). No in-flight sessions (next ID 0055).
• Two P1 tickets tied for highest priority: #59 (P1 bug — spurious macOS "control other applications" prompt) and #60 (P1 feature — live turn progress). Brainstorming produces a spec; a feature needs a design (§4.3 R3), so #60 was the fit. #59 (bug) → a coding session.
• Highest INV in use across the content-repo specs: INV-42.

Session arc (turn-by-turn)

1. Gate + classify. Launch prompt classified as brainstorming; ran wgl-brainstorming.
2. Claim (peek → gate → claim). claim-session-id.sh --dry-run → no in-flight sessions, next ID 0055. Claimed --type brainstorming (placeholder at 16cca30). Verified clean pushed main baseline.
3. Orient. Surveyed the open tracker. Picked #60 (P1 feature, design needed) over #59 (P1 bug, coding-session work). Read #60 in full.
4. Ground in code (read-only). Read liveTurn.ts (runEditTurn → agent.run() as one opaque promise; module is deliberately vscode-free), both call sites (extension.ts:232 editSelection, trackChangesPreview.ts:232 preview askClaude — both wrap the turn in withProgress("asking Claude…")), the injectable editTurn seam (trackChangesPreview.ts:56, for host-E2E stubbing), and the @cline/sdk event API: @cline/agents Agent exposes subscribe(listener) → unsubscribe, run(), abort(); AgentRuntimeEvent (in @cline/shared/dist/agent.d.ts) carries assistant-text-delta (+accumulatedText), tool-started|updated|finished, usage-updated, lifecycle events. The enabler the issue cites is real.
5. Brainstorm forks (superpowers:brainstorming). Skipped the visual companion (choices are conceptual/native-UI, not visual mockups). Presented three forks via AskUserQuestion; operator picked all three recommendations:
   • Surface → notification activity-line + token count and a shared "Cowriting" OutputChannel streaming full assistant text. (Rejected: webview relay can't cover the editSelection path; status-bar-only; OutputChannel- primary.)
   • Content → activity + token count (reasoning text not surfaced).
   • Cancellation → cancellable notification → agent.abort() → "cancelled", proposes nothing (reflect + cancel button).
6. Design presented + approved. Three-unit architecture (pure turnProgress.ts reducer → runEditTurn extended with onProgress + AbortSignal → both call sites relay via a shared liveProgressUi); layering rule keeps liveTurn.ts/turnProgress.ts vscode-free; INV-43..47. Two sub-decisions (OutputChannel auto-reveal gated by a new setting; append-not- clear) confirmed. Operator: "design looks right."
7. Spec written + self-review. specs/coauthoring-live-progress.md authored in house Solution-Design format. Self-review: no placeholders, INV-43..47 (no collision with ≤42; INV-8/21/39 are correct citations), internally consistent, single-feature scope.
8. Operator: "Implement it." Per the pipeline, that's the brainstorm→coding handoff (one SPEC = one plan = one execution, §4.3). Finalized this brainstorming session (below); a fresh wgl-planning-and-executing session plans + builds #60.

Cut state (at finalize)

• Spec graduated. submit-spec.sh --status graduated → vscode-cowriting-plugin-content specs/coauthoring-live-progress.md at 3bd1ae5.
• Code repo: clean main; no code changes this session (brainstorming). A local stray specs/coauthoring-live-progress.md remains untracked in the code repo (an rm cleanup was permission-denied; harmless — canonical copy is in the content repo).
• Memory: added session-0055-live-progress-spec-graduated.md + index line.

Next-session prompt

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

Deferred decisions

• OutputChannel auto-reveal (fires every Claude turn): decided to auto-show(true) (preserveFocus) on the first text delta, gated by a new setting cowriting.liveProgress.revealOutput (default true). Operator confirmed the design including this.
• OutputChannel history: decided to append per-turn (with a header) rather than clear, so it doubles as a debug log. Operator confirmed.
• Stray local spec file: rm -rf specs/ was permission-denied; left the untracked local copy in the code repo (cosmetic; content repo holds the canonical copy).
