+## Implementation Tasks
+
+Before closing this review, synthesize the findings above into a flat list of
+build-actionable tasks. Each task derives from a specific finding — no padding.
+Emit the markdown section AND write a JSONL artifact that `/autoplan` can
+aggregate across phases.
+
+### Markdown section (always emit)
+
+```markdown
+## Implementation Tasks
+Synthesized from this review's findings. Each task derives from a specific
+finding above. Run with Claude Code or Codex; checkbox as you ship.
+
+- [ ] **T1 (P1, human: ~2h / CC: ~15min)** — <component> — <imperative title>
+  - Surfaced by: <section name> — <specific finding text or line reference>
+  - Files: <paths to touch>
+  - Verify: <test command or manual check>
+- [ ] **T2 (P2, human: ~30min / CC: ~5min)** — ...
+```
+
+Rules:
+- P1 blocks ship; P2 should land same branch; P3 is a follow-up TODO.
+- If a finding produced no actionable task, do not invent one.
+- If a section had zero findings, emit `_No new tasks from <section>._`
+- Effort uses the AI-compression table from CLAUDE.md.
+
+### JSONL artifact (always write, even if zero tasks)
+
+`/autoplan` reads this file to aggregate across phases. Build each line with
+`jq -nc` so titles and source findings containing quotes, newlines, or
+backslashes serialize cleanly — never use hand-rolled `echo` / `printf`.
+
+```bash
+eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)"
+TASKS_DIR="${HOME}/.gstack/projects/${SLUG:-unknown}"
+mkdir -p "$TASKS_DIR"
+TASKS_FILE="$TASKS_DIR/tasks-eng-review-$(date +%Y%m%d-%H%M%S).jsonl"
+COMMIT=$(git rev-parse HEAD 2>/dev/null || echo unknown)
+BRANCH=$(git branch --show-current 2>/dev/null || echo unknown)

+
+# Repeat ONE jq invocation per task identified during this review.
+# Substitute the placeholders inline with shell variables you set per task:
+#   TASK_ID (T1, T2, ...), PRIORITY (P1/P2/P3), COMPONENT, TITLE,
+#   SOURCE_FINDING, EFFORT_HUMAN, EFFORT_CC, FILES_JSON (a JSON array literal
+#   like '["browse/src/sanitize.ts","browse/src/server.ts"]').
+jq -nc \
+  --arg phase 'eng-review' \
+  --arg run_id "$RUN_ID" \
+  --arg branch "$BRANCH" \
+  --arg commit "$COMMIT" \
+  --arg id "$TASK_ID" \
+  --arg priority "$PRIORITY" \
+  --arg component "$COMPONENT" \
+  --arg effort_human "$EFFORT_HUMAN" \
+  --arg effort_cc "$EFFORT_CC" \
+  --arg title "$TITLE" \
+  --arg source_finding "$SOURCE_FINDING" \
+  --argjson files "$FILES_JSON" \
+  '{phase:$phase, run_id:$run_id, branch:$branch, commit:$commit, id:$id, priority:$priority, component:$component, files:$files, effort_human:$effort_human, effort_cc:$effort_cc, title:$title, source_finding:$source_finding}' \
+  >> "$TASKS_FILE"
+```
+
+If `jq` is not installed, fall back to skipping the JSONL write and warn
+the user to install jq for autoplan aggregation. Never hand-roll JSONL.
+
+If zero tasks were identified in this review, still touch the JSONL file
+(`: > "$TASKS_FILE"`) so the aggregator sees that the phase produced output
+this run (an empty file means "ran, no findings" — distinct from "didn't run").
