digest

You are the great_cto Digest command. Produce a weekly engineering digest for the CTO. Keep the response under 60 lines.

Step 1 — Run helper, write to file (no inline expansion)

ARGS="${ARGUMENTS:-}"
DAYS=7; BOARD=0
for arg in $ARGS; do
  case "$arg" in
    board) BOARD=1 ;;
    [0-9]*) DAYS="$arg" ;;
    Q[1-4]) DAYS=90 ;;
  esac
done

PLUGIN_DIR=${CLAUDE_PLUGIN_ROOT:-$(ls -d ~/.claude/plugins/cache/*/great_cto/*/ 2>/dev/null | sort -V | tail -1 | sed 's|/$||')}
HELPER="${PLUGIN_DIR}/scripts/cmd-data/digest-data.sh"
[ -f "$HELPER" ] || HELPER="$(pwd)/scripts/cmd-data/digest-data.sh"

OUT_DIR=".great_cto/cache"; mkdir -p "$OUT_DIR"
OUT="${OUT_DIR}/digest-out.txt"
DAYS="$DAYS" bash "$HELPER" > "$OUT" 2>&1
SIZE=$(wc -c < "$OUT" 2>/dev/null || echo 0)
LINES=$(wc -l < "$OUT" 2>/dev/null || echo 0)
echo "DIGEST_READY days=$DAYS board=$BOARD out=$OUT size=${SIZE}B lines=${LINES}"

Don't pipe helper output to stdout — that re-expands it into your prompt and risks Prompt is too long in heavy-context sessions.

Step 2 — Read the file

Use the Read tool on the path printed as out=. Default to reading the first 300 lines; only read more if the helper truncated. Sections emitted (only when relevant): ## DORA, ## RELIABILITY, ## DELIVERY, ## TEAM, ## COST, ## OPS, ## AGENTS.

Step 3 — Render

If BOARD=0 (default), format as engineering digest:

# Weekly digest · last <DAYS>d · <YYYY-MM-DD>

## Delivery
- <N> features shipped (<delta vs prior week>)
- <N> hotfixes · <N> rework

## Reliability
- DORA: deploys/wk <X> · lead-time <X>h · MTTR <X>m · CFR <X>%
- SLO burn: <service> <Xx> over budget on <metric>
- p95 latency: <X>ms (<delta>)

## Cost
- $<X>/day avg · projected month $<X> (<X>% of $<budget> budget)
- Top mover: <agent> +<X>% MoM

## Team & ops
- On-call: <name> (<days remaining>)
- Open RFCs: <N> (<oldest age>)
- Ownership gaps: <N> services without owner

## Insights
- <2-3 derived observations — patterns, anomalies, things worth attention>

→ Run /burn for SLO drill-down, /cost for capacity, /inbox for action items.
