# Session 0055.0 — Transcript
> App: vscode-cowriting-plugin
> Start: 2026-06-22T23-19 (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).
