Team Design — Where Are We Going?

Run the DESIGN phase. This is the pipeline's only human gate — get alignment here before investing in detailed planning.

Input

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

The design-author reads:

• $ARGUMENTS/task.md — what we're building (intent)
• $ARGUMENTS/questions.md — the questions that drove research
• $ARGUMENTS/research.md — what exists (facts)

Resolve the artifact directory by running this self-contained block (one bash call — agent threads reset cwd between calls):

# 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="research.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
  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). 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 research.md),

do not hard-error. Fire AskUserQuestion with a Setup header and labeled options:

• Run the producer — run /team-research docs/plans/<id>/ to produce the

missing research.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.
2. Dispatch design-author, which:

a. Presents 3–5 open design questions to the user via the built-in AskUserQuestion tool (multi-choice with labeled trade-offs) b. Waits for the user's structured answers c. Writes $ARGUMENTS/design.md with frontmatter approved: false, approved_at: null, revision: 0

1. Human gate. Present the design in full, then use

AskUserQuestion to capture the verdict. Use a single question with a Decision header and these options:

• Approve — design is ready; advance to STRUCTURE.
• Request changes — describe what to revise; re-dispatch

design-author with the user's feedback verbatim.

• Reject — abandon this design and start over.

• On Approve → edit $ARGUMENTS/design.md frontmatter to set

approved: true and approved_at: <ISO-8601>.

• On Request changes → re-dispatch design-author with the user's

feedback verbatim. The agent re-drafts and increments revision: <n+1>. Cap at revision: 5; beyond that, escalate to the user.

1. Stop once `$ARGUMENTS/design.md` carries `approved: true`.

Completion

Report design path and tell the user: "Next: run `/team-structure docs/plans/<id>/`"
