App: dev-claude-plugin Start: 2026-06-22T08-42 (PST) End: 2026-06-22T08-54 (PST) Type: planning-and-executing Posture: yolo Claude-Session: 037a56a3-91e5-4e08-8023-095c65246353 Status: FINALIZED

Launch prompt

/goal F3 — wgl-tech-design (#127): new gate-lifter skill authoring the SPEC Engineering lens, accreting after brd/prd.
Part of the staged-gate SDLC refactor (Epic #125). F1 (handbook accretion) and F2 (wgl-brainstorming --lenses brd|prd) shipped. F3 adds the Engineering-lens gate-lifter that accretes the engineering lens into the SAME SPEC after the business/product lenses.

Plan

Anchor: design engineering/docs/sdl-pipeline-refactor-brief.md (R2a, locked Solution Design) — Feature #127 (parent Epic #125). Eligibility: ELIGIBLE (R2a). Goal: F3 of the staged-gate SDLC refactor — build wgl-tech-design, a new gate-lifter session type that authors the SPEC Engineering lens (Technical Design §6) by accretion into the same SPEC the brd/prd lenses created, at the architecture/contract altitude (NO task breakdown — that's F4), ending at a terminal review gate.

Scope boundary (per #127):

  • In F3: the wgl-tech-design skill; make the type claimable + posture-stamped (claim-session-id.sh type→posture single-home → tech-design = careful) + its test; thin-SPEC path for leaf issues; cites reconciled handbook (F1), reuses existing deterministic tools.
  • Deferred to F5 (#129): registering tech-design in the session-gate hook type table + the wgl-session-finalize dispatch table + stale-ref sweep. (Finalize Step-0 fallback covers the transitional gap.)

Pre-state

  • Branch claude/pedantic-carson-35d379 (harness-provided worktree) tracking a clean, pushed origin/main at bfa8efe (F2 / v0.57.0 merge).
  • Plugin pin loaded by this session: 0.57.0.
  • Six stale --INPROGRESS placeholders (00350076, 9+ days old) in the app's session-history — orphaned crashes, none flagged ENDED-UNFINALIZED, none live. No live concurrent same-app session.

Arc

  1. Classified + opened the session. Session gate → planning-and-executing (build a skill, plan→code). Invoked wgl-planning-and-executing.
  2. Claimed session 0078 (peek → no live concurrency → atomic claim). Stamped Type: planning-and-executing, Posture: yolo. Local placeholder in ~/.wgl.
  3. Verified baseline clean/pushed; CLAUDE.md already imports @~/.claude/wiggleverse.md.
  4. Studied the F2 pattern + the locked brief. Read engineering/docs/sdl-pipeline-refactor-brief.md (design-track step 4 — wgl-tech-design authors the engineering lens, no task breakdown; two altitudes stay distinct), the shipped wgl-brainstorming/SKILL.md (--lenses brd|prd accretion model), lenses-for-type.sh, and issue #127 (in-scope vs F5 non-goals). Confirmed via solution-design/GUIDE.md that the engineering lens = Technical Design §6, and completes the SPEC.
  5. Eligibility (Step 8.5): check-issue-eligibility.sh --design <brief> --for implementation-plan → ELIGIBLE (R2a, locked Solution Design). #127 itself is a bare type/feature (R3-ineligible) — anchored on the brief instead.
  6. Built F3 (4 tasks):
    • claim-session-id.sh: added tech-design to --type validation + error msg + the type→posture single-home (→ careful, design INV-1). Header doc updated.
    • test-posture-stamp.sh: added tech-design → careful assertion. → 11/11 pass.
    • skills/wgl-tech-design/SKILL.md: the new gate-lifter — front-half reuse (claim/baseline/memory Steps 17), engineering-lens accretion into the existing SPEC, thin-SPEC path for a leaf that skipped brd/prd, careful-by-construction + terminal gate, the load-bearing architecture/contract-only (no task breakdown) boundary, eligibility reuse (--for solution-design R1; lenses-for-type.sh R1R3), finalize participation (spec addendum) + a bootstrap note on F5 wiring. Cites handbook §3.3/§4.3 + GUIDE rather than restating (§4.1).
    • plugin.json: 0.57.0 → 0.58.0.
  7. Verified: test-posture-stamp.sh 11/11 · test-session-id-ownership.sh 20/20 · test-lenses-for-type.sh 14/14 · test-issue-eligibility.sh 14/14 · lint.sh --check-bump clean (shellcheck skipped — not installed; later confirmed 0.57.0 → 0.58.0 with skills changes).
  8. Shipped: committed 869ce50, pushed, opened PR #131 (Gitea API; the issues token 403'd on PR scope → used the default per-host wgl-gitea-token-git.wiggleverse.org), merged to main (72a2576). #127 closed (PR body Closes #127).
  9. Finalize: clean tree, no open PRs. No separate writing-plans artifact (plan was inline) → nothing to submit-plan.sh. Meta/plugin change → no PPE pipeline stage. Cache-lag: loaded 0.57.0 < shipped 0.58.0 → ran update-plugin.sh0.57.0 → 0.58.0 made live (applies to new sessions; restart//clear to load). Memory updated; transcript published.

Cut state

  • origin/main @ 72a2576 — F3 merged, v0.58.0 shipped and made live.
  • wgl-tech-design skill exists and is invocable (lifts the gate when invoked directly). tech-design is a claimable session type stamping careful posture.
  • #127 closed. Epic #125: F1✓ F2✓ F3✓ — F4 (#128) next, then F5 (#129).
  • Worktree pedantic-carson-35d379 left for harness cleanup (branch merged/clean).

Deferred decisions

  • F3/F5 boundary on finalize dispatch. #127's scope lists "finalize participation" as in-scope but "finalize dispatch table" as an F5 non-goal — a genuine tension. Resolved: F3 makes the type claimable + posture-stamped and the skill describes its finalize participation; the actual case registration in wgl-session-finalize (and the session-gate classifier table) is left to F5. Until then, finalize's Step-0 fallback routes a tech-design SPEC to the spec addendum. Low-confidence call logged here for review; the gap is benign during the bootstrap (the new types aren't yet driven by the pipeline gate).
  • Engineering lens NOT added to lenses-for-type.sh. That script is deliberately the brainstorming {brd, prd} pair; the engineering lens applicability is handled by reusing check-issue-eligibility.sh --for solution-design (R1) + reading the brd/prd verdict for the feature-vs-leaf path. No new deterministic tool invented (§4.2).

Next-session prompt

/goal F4 — split wgl-planning-and-executing into wgl-writing-plans + wgl-executing-plans (#128, Epic #125): one plan = one execution; the SPEC's native Task→Step structure IS the decomposition (no per-slice loop); thin wrappers at native superpowers grain. Anchor on the locked brief (R2a). Then F5 (#129) wires the gate/finalize tables for the F3+F4 types + stale-ref sweep.
