Team Structure — How Do We Get There?

Run the STRUCTURE phase. It runs autonomously and advances to PLAN — there is no human gate here. Design is the pipeline's only human gate.

Input

$ARGUMENTS is the artifact directory: docs/plans/<id>/. If empty, the discovery block below resolves it.

The structure-planner reads:

• $ARGUMENTS/design.md (must carry approved: true in its frontmatter)
• $ARGUMENTS/research.md
• $ARGUMENTS/task.md (for cross-reference; not for re-litigating intent)

Resolve the artifact directory by running this self-contained block (one bash call — agent threads reset cwd between calls). The predecessor filter requires an approved design.md, so unapproved candidates are skipped:

# Three-tier artifact-directory discovery (archetype A).
# ID_RE + PHASE_FILES canonical from hooks/session-start-recover.mjs.
# PHASE_FILES recency mirrors findActiveTopic() in session-start-recover.mjs.
# NOTE: this block is duplicated across 8 skills by design (see docs/architecture.md); future: shared discover-topic.sh.
ID_RE='^([A-Za-z][A-Za-z0-9_]*-[0-9]+|[0-9]{4}-[0-9]{2}-[0-9]{2})-[a-z0-9][a-z0-9-]*$'
PHASE_FILES="task questions research design structure plan"
PRED="design.md"            # predecessor artifact this skill consumes
# Tier 1 — explicit: $ARGUMENTS names an existing dir → use verbatim.
if [ -n "$ARGUMENTS" ] && [ -d "$ARGUMENTS" ]; then
  echo "$ARGUMENTS"; exit 0
fi
# Tier 2 — discover: newest ID_RE dir under docs/plans/ that holds PRED.
best=""; best_mtime=-1
# Assumes cwd is the repo/worktree root (where docs/plans/ lives).
for dir in docs/plans/*/; do
  name="$(basename "$dir")"
  printf '%s' "$name" | grep -qE "$ID_RE" || continue   # ID_RE filter
  [ -f "$dir$PRED" ] || continue                        # predecessor filter
  grep -qE '^approved:[[:space:]]*true[[:space:]]*$' "$dir$PRED" || continue
  m=-1
  for p in $PHASE_FILES; do
    f="$dir$p.md"
    [ -f "$f" ] || continue                             # skip racing/absent
    s="$(stat -f %m "$f" 2>/dev/null || stat -c %Y "$f" 2>/dev/null)" || continue
    [ "${s:-0}" -gt "$m" ] && m="$s"                    # max-mtime over PHASE_FILES
  done
  [ "$m" -gt "$best_mtime" ] && { best_mtime="$m"; best="$dir"; }
done
[ -n "$best" ] && { echo "$best"; exit 0; }
# Tier 3 — none found: print nothing → fall to AskUserQuestion (prose below).

• If the block printed a path, use it as $ARGUMENTS for the rest of this skill (tier 1 explicit arg, or tier 2 discovery of an approved predecessor). When the path came from tier 2 (no explicit arg), announce the resolved directory to the user before proceeding, so an auto-picked topic is never silent.
• If the block printed nothing (tier 3 — no directory holds an approved design.md), do not hard-error. Fire AskUserQuestion with a Setup header and labeled options:
  • Run the producer — run /team-design docs/plans/<id>/ to produce or approve design.md.
  • Provide a path — the user supplies the docs/plans/<id>/ directory directly (run ls docs/plans/ to find your topic directory).

Execution

Follow skills/progress-tracking/SKILL.md: when this procedure has two or more steps, seed one todo item per step before starting and mark each complete as you go.

1. Use the directory resolved in ## Input (the approval grep there already confirmed design.md carries approved: true).
2. Dispatch structure-planner, which writes $ARGUMENTS/structure.md with vertical slices. The artifact carries plain frontmatter (topic, date, phase: structure) — no approval fields, because structure is not human-gated.
3. No human gate. Do not present the structure for approval — design is the only human gate. Within a full /team run the orchestrator advances to PLAN automatically; run standalone, this skill stops after writing the structure and reports the next command.
4. Stop once $ARGUMENTS/structure.md exists.

Completion

Report the structure path. When run standalone, tell the user: "Next: run /team-plan docs/plans/<id>/" (Within a full /team run the orchestrator advances to PLAN automatically.)
