## Launch prompt

> We should add creating a worktree (in a different dir than main) to the coding
> session init, and cleaning up the worktree after merging to main in the finalize

## Plan

A **design-only** coding session. Brainstorm the worktree-in-bookends feature,
write + merge the design doc, defer implementation. Output: one approved design
doc merged to `main` via PR; implementation (effort A) and the larger taxonomy
realignment (effort B) recorded as the next goals.

## Pre-state

- Source `plugin.json` at **0.16.0** (merged session 0018, PR #10). Installed
  cache lags (re-install pending) — irrelevant to a design-only session.
- Branch `main`, clean; fast-forwarded one commit on init (a freshly-pushed
  feedback note, `resolver-nested-worktree-ambiguous`, which turned out central).
- The handbook (§5.4) endorses worktrees for *parallel* sessions but no bookend
  sets one up.

## Turn-by-turn arc

1. **Session gate + claim.** Classified the opening prompt as a **coding**
   session (≥90%), invoked `wgl-session-coding-init`. Peeked (dry-run: no
   in-flight sessions), claimed **0019**, fast-forwarded `main`, confirmed the
   `@~/.claude/wiggleverse.md` import.

2. **Found the coupling.** The commit pulled on init was the open feedback note
   `2026-06-05T18-13-resolver-nested-worktree-ambiguous`: `resolve-app.py` errors
   "ambiguous" from a nested `.worktrees/` checkout. Adding worktrees would walk
   every checkpoint-publish/finalize into that bug → the resolver fix is in-scope.

3. **Brainstorming.** Invoked `superpowers:brainstorming`. Asked scope (worktree
   for every session vs. only parallel) → operator: **always, every coding
   session**, and **"we can just use the superpowers worktree skill"** (delegate
   mechanics to `superpowers:using-git-worktrees`, don't build wgl-native).

4. **Read the surface.** coding/spec/discovery init SKILLs, finalize SKILL +
   `finalize-core.md`, `resolve-app.py`, `using-git-worktrees`. Confirmed spec/
   discovery delegate their front half to coding-init ("Steps 1–7 identical"), so
   one Step 6b is inherited by all three.

5. **Scope grew, then was bounded.** Operator added: do spec-init + discovery-init
   too (they author solution designs / BDDs). Then proposed a **taxonomy
   realignment** — `discovery=/brainstorming`, `spec-init→plan-init=/writing-plans`,
   `coding=/executing-plans`. Flagged this as a distinct, larger effort (effort B)
   vs. the worktree change (effort A). Operator chose **ship A first, then design
   B**. Operator also chose to **update engineering §5.4** ("parallel" → "every
   tracked session") this effort (cross-repo).

6. **Dogfooding caught a refinement.** Set up isolation for the implementation via
   the native **`EnterWorktree`** (`.claude/worktrees/`). Ran `resolve-app.py`
   from inside it → **reproduced the "ambiguous" error live**, but via
   `.claude/worktrees/` — a path the feedback note (which only saw `.worktrees/`)
   never mentioned. This promoted **identity-dedupe (git common-dir key)** to the
   *primary* resolver fix, with the dir-prune (now `.claude` + `.worktrees`) as
   backstop. Updated the design doc accordingly.

7. **Design doc → commit → review → merge.** Wrote
   `docs/superpowers/specs/2026-06-06-session-worktrees-design.md`, self-reviewed,
   committed on the worktree branch. Operator: **"spec is good. merge and finalize
   this session."** Pushed `feat/session-worktrees`, created **PR #11** via the
   Gitea API (no gh/tea CLI), merged it (merge `2eea11b`), deleted the remote
   branch.

8. **Teardown + finalize.** `ExitWorktree remove` (work safely in `main`),
   ff-pulled `main`, verified the design doc landed **and the resolver now
   resolves cleanly** (`APP_NAME='dev-claude-plugin'`, exit 0) with the worktree
   gone — an end-to-end dogfood of the designed create→merge→teardown flow.
   Updated memory; finalized.

## Deferred decisions

_None._ Every fork was decided jointly via `AskUserQuestion`:
scope = all sessions; delegate to `superpowers:using-git-worktrees`; update §5.4
too; ship effort A before designing effort B.

## Final state

- **Merged to `main`:** the design doc only (PR #11, merge `2eea11b`). No code,
  skill, script, or version change — implementation is the next goal.
- Worktree torn down; `git worktree list` shows only the main clone; resolver
  clean. No open PRs.
- Memory updated: `Next /goal:` = implement effort A; effort B recorded as a
  deferred follow-up.

## Next-session prompt

```
/goal Implement effort A — worktrees in the session bookends, per docs/superpowers/specs/2026-06-06-session-worktrees-design.md: coding-init Step 6b delegates to superpowers:using-git-worktrees; spec/discovery-init inherit it; type-neutral finalize teardown after merge (native ExitWorktree remove / git worktree remove, gated on merged-or-clean); resolve-app.py identity-dedupe (git common-dir key) + prune .claude/.worktrees (closes the resolver-nested-worktree-ambiguous feedback note); broaden engineering §5.4 to "every tracked session"; bump plugin.json 0.16.0→0.17.0. Start with writing-plans from the design doc.
```

After effort A: design **effort B** (session-taxonomy realignment onto the
superpowers brainstorming→writing-plans→executing-plans pipeline, incl. the
`spec-init`→`plan-init` rename), and the still-pending 0.16.0 re-install +
flotilla-alignment-live check.
