Session 0021.0 — Transcript

App: dev-claude-plugin Start: 2026-06-07T08-30 (PST) End: 2026-06-07T15-58 (PST; ended on /clear) Type: coding Status: FINALIZED (post-hoc reconstruction).

⚠️ Reconstructed record. This session ended on /clear without a completed finalize — the session-end-finalize-guard hook banner-stamped it as ended-unfinalized (see below). Its live conversation context was lost; it was finalized later, on 2026-06-08, as a best-effort cleanup grounded in the placeholder's own Plan section plus git history. Treat this as a reconstruction, not a verbatim transcript.

Launch prompt

/goal Ensure that implementation never happens without an implementation plan.
Ensure that implementation plans are never written without a solution design
that includes that slice

Plan (as captured live in the placeholder)

Goal: Enforce the build chain in the plugin — no implementation without an implementation plan; no implementation plan without a Solution Design that includes that slice.

Recursive by nature: honoring the goal while building it means design → plan → implement. Session opened as coding (operator choice).

Design decisions (operator-confirmed via AskUserQuestion):

Enforcement strength: soft, house-style (verify → route → ask-when-unsure → fail open), matching the session-gate + finalize-on-goal posture. No hard blocking hook.
Artifacts (map to existing vocab): Solution Design = SPEC.md / spec-RFC (§3.3) — or a committed docs/superpowers/specs/ design doc where a repo designs in-repo — that includes the slice; Implementation Plan = docs/superpowers/plans/ (writing-plans output); Implementation = via superpowers:executing-plans.
Scope: focused enforcement layer only on the current three session types (keep spec/coding/discovery names); Effort B (full superpowers realignment + spec-init→plan-init rename) stays deferred.

Approach (as planned): Document the invariant canonically in SESSION-PROTOCOL.md (docs lead automation, §4.1), then wire coding-init to gate on it (G1: plan required before implementing; G2: covering Solution Design required before a plan) and route implementation through superpowers:executing-plans. Light touch on session-gate + spec-init. Bump 0.17.0 → 0.18.0.

What actually happened to this work (reconstructed)

The session's planned standalone enforcement layer at 0.18.0 was not shipped as planned — it was redirected:

v0.18.0 (PR #13, 275c633) instead became the superpowers verbiage rename (the three session types → brainstorming / writing-plans / executing-plans) — the operator's "effort B" realignment that this session's Plan had explicitly deferred.
The build-chain invariant this /goal was chasing was then absorbed structurally by the two-session model (v0.22.0, PR #22): wgl-writing-plans folded into wgl-brainstorming (= reviewed spec), and wgl-planning-and-executing came to own the write-the-plan step before executing. The build chain is encoded in the session topology rather than as a separate soft-enforcement hook.

So the /goal here is best read as a productive provocation: it surfaced the "design → plan → implement" chain that the later two-session model made load-bearing, rather than producing its own merged artifact.

Pre-existing note (carried from the live placeholder)

Session 0020 is a dead/unfinalized placeholder whose work (the session-end-finalize-guard hook, PR #12) already merged; flagged for cleanup, out of scope here.

(That cleanup is the same 2026-06-08 pass that finalized this transcript.)

Cut state / outcome

No standalone merged artifact attributable to this session ID; its line of thought lives on in v0.22.0's two-session model.
Plugin source is now at v0.23.0; tree clean and pushed.

Deferred decisions

None recoverable (context lost on /clear). The live placeholder's deferred-decisions section was empty.

Ended-unfinalized banner (original, from the SessionEnd guard)

⚠️ This session ENDED WITHOUT A COMPLETED FINALIZE at 2026-06-07T15-58 (PST; reason: clear). This placeholder holds only the last local checkpoint; the rich finalize (narrative, memory update, PR/branch survey) did not run. The next session should ADOPT and finalize this transcript via wgl-session-finalize, which replaces this placeholder with the finalized record.
