Weekly Aeoncard

${var} — window + delivery control.

• empty → weekly card: last 7 days + all-time, render the image, notify.
• dry-run → render the image + report + dashboard spec but send no notification (artifacts still write). Combine with a window, e.g. dry-run 30.
• integer N → override the weekly window to the last N days (default 7, cap 90). Example: 14, 30.

Today is ${today}. Turn this instance's own token ledger (memory/token-usage.csv) into a one-glance recap: how many tokens it burned this week, how many since it started, which skills dominate — rendered as a self-contained SVG card an operator can screenshot and share. Every number is measured from the ledger; nothing is fetched, sampled, or estimated. The heavy lifting is in skills/weekly-aeoncard/render_card.py (pure Python stdlib, deterministic) so you orchestrate, not hand-compute.

Steps

1. Parse ${var} → window + mode.

   V="$(echo "${var}" | tr '[:upper:]' '[:lower:]' | xargs)"
   MODE=execute; case "$V" in dry-run*) MODE=dry-run; V="${V#dry-run}"; V="$(echo "$V" | xargs)";; esac
   WINDOW_DAYS=7; case "$V" in ''|*[!0-9]*) : ;; *) WINDOW_DAYS="$V";; esac
   [ "$WINDOW_DAYS" -gt 90 ] 2>/dev/null && WINDOW_DAYS=90
   [ "$WINDOW_DAYS" -lt 1 ] 2>/dev/null && WINDOW_DAYS=7
   

2. Guard the ledger. The recap is synthesis-only — no ledger, nothing to show.

   CSV=memory/token-usage.csv
   if [ ! -s "$CSV" ] || [ "$(wc -l < "$CSV")" -lt 2 ]; then
     ./notify "weekly-aeoncard skipped: memory/token-usage.csv absent or empty (no runs recorded yet)"
     exit 0   # WEEKLY_AEONCARD_NO_DATA
   fi
   

3. Derive the instance name + image link. From the git origin, so the card self-labels and the notification deep-links the committed SVG.

   REMOTE="$(git remote get-url origin 2>/dev/null)"
   REPO="$(echo "$REMOTE" | sed -E 's#.*github.com[:/]([^/]+/[^/.]+)(\.git)?/?$#\1#')"
   INSTANCE="${REPO#*/}"; [ -n "$INSTANCE" ] || INSTANCE=aeon
   SVG="output/images/weekly-aeoncard-${today}.svg"
   IMG_LINK="https://github.com/${REPO}/blob/main/${SVG}"
   

4. Render the card + artifacts. One call writes the SVG (canonical image), a best-effort PNG, the markdown report, the dashboard spec, and appends the run log. It prints a one-line JSON summary on stdout — capture it.

   mkdir -p output/images output/articles apps/dashboard/outputs
   # The PNG (for inline Telegram) needs a rasterizer. The workflow stages `rsvg-convert`
   # (librsvg2-bin) for this skill before the run — the agent allowlist blocks in-run
   # pip/apt. render_card.py uses cairosvg if importable, else rsvg-convert, else SVG-only.
   SUMMARY="$(python3 skills/weekly-aeoncard/render_card.py \
     --csv "$CSV" --today "${today}" --window-days "$WINDOW_DAYS" \
     --instance "$INSTANCE" --img-link "$IMG_LINK" \
     --out "$SVG" \
     --png "output/images/weekly-aeoncard-${today}.png" \
     --report "output/articles/weekly-aeoncard-${today}.md" \
     --dashboard "apps/dashboard/outputs/weekly-aeoncard.json" \
     --log "memory/logs/${today}.md")"
   RC=$?
   if [ "$RC" -ne 0 ]; then
     ./notify "weekly-aeoncard: render failed (rc=$RC) — ledger unreadable"
     exit 0
   fi
   

   All writes land under output/ and apps/dashboard/outputs/ — paths the run commits. The PNG is a raster copy for inline Telegram delivery (needs cairosvg or rsvg-convert); if neither is available the SVG stands alone as the canonical image and the notify degrades to a text recap + link.

5. Read the numbers back. Parse $SUMMARY for the notification (it holds week_human, week_runs, life_human, life_runs, since, cache_read_pct, top_week):

   WK=$(echo "$SUMMARY" | jq -r .week_human); WKR=$(echo "$SUMMARY" | jq -r .week_runs)
   LF=$(echo "$SUMMARY" | jq -r .life_human); LFR=$(echo "$SUMMARY" | jq -r .life_runs)
   SINCE=$(echo "$SUMMARY" | jq -r .since)
   TOP=$(echo "$SUMMARY" | jq -r '[.top_week[:3][] | "\(.[0]) \(.[1]/1e6|floor)M"] | join(", ")')
   PNG=$(echo "$SUMMARY" | jq -r '.png // ""')   # empty when no rasterizer was available
   

6. Log. The render step already appended a ### weekly-aeoncard block to memory/logs/${today}.md (window, weekly + all-time totals, top skills, image path, WEEKLY_AEONCARD_OK). Do not duplicate it.

7. Notify. If MODE is dry-run, skip this step (log WEEKLY_AEONCARD_DRY_RUN and stop — the image, report, and dashboard spec are already written). Otherwise send the recap via ./notify. When a PNG rendered, pass it with --photo so the card shows inline on Telegram (the caption carries the numbers); the SVG link stays in the body for the crisp vector. When no PNG rendered, the same call without --photo degrades to the text recap + link:

   [ "$MODE" = dry-run ] && exit 0
   BODY="This week (${WINDOW_DAYS}d): ${WK} tokens · ${WKR} runs
   All-time: ${LF} tokens · ${LFR} runs (since ${SINCE})
   Top this week: ${TOP}
   Card: ${IMG_LINK}"
   if [ -n "$PNG" ] && [ -s "$PNG" ]; then
     ./notify --title "Weekly Aeon Card — ${INSTANCE}" --photo "$PNG" "$BODY"
   else
     ./notify --title "Weekly Aeon Card — ${INSTANCE}" "$BODY"
   fi
   

Network note

The skill issues no gh api and puts no secrets on the command line. Stats are read from memory/token-usage.csv; the card is rendered by skills/weekly-aeoncard/render_card.py using only the Python standard library (deterministic — ${today} is passed in, never read from the clock). To also emit a raster PNG it uses cairosvg (best-effort pip install) or an rsvg-convert fallback — both optional; without them the run still succeeds with the SVG as the image. The image link is built from git remote get-url origin (a local read). Delivery goes through ./notify, which owns the only outbound calls: Telegram sendPhoto (when --photo is set) or sendMessage, and stages to .pending-notify/ for post-run redelivery.

Constraints

• Synthesis-only. Every number is measured from the ledger. If the ledger is missing a skill's runs, that skill simply doesn't appear — never invent rows.
• Write skill. It renders and commits artifacts, so it is mode: write (the read-only tier withholds Bash(python3:*) — an interpreter is a write vector — so a Python-rendered card cannot run read-only; a Node renderer could, but this skill is honestly a write). All file writes still happen inside render_card.py (Python open()) for deterministic, single-shot output.
• Idempotent. Same-day reruns overwrite output/images/weekly-aeoncard-${today}.svg, the report, and the dashboard spec; the log block appends (one per run) so reruns show drift.
• The SVG is the deliverable. The PNG is a convenience for chat/social; its absence is never an error.
