Install: claude install-skill zauberzeug/game-of-cards
## Preflight
If any `!` block below shows `goc: command not found`, `Permission for this action has been denied`, or `no such file or directory: .game-of-cards/deck/`, **stop and invoke `Skill(kickoff)` first**. Kickoff detects which setup step is missing (CLI not installed, Bash allowance not granted, project state not scaffolded) and walks the user through it. Re-invoke this skill only after kickoff completes.
## Context
!`goc --status done --json | head -100`
# Retrospective
Scrum's **Sprint Retrospective** (Schwaber & Sutherland) applied to the
full card history. This skill looks *backwards* at completed work —
something no other skill does. `Skill(audit-deck)` hunts NEW defects
in the codebase; this skill reads the last N `log.md` closure entries,
clusters by tag, and surfaces patterns: which failure modes recur,
which closures mention the same root cause, which clusters are candidates
for a generalization card.
**Read-only** — this skill inspects history and proposes actions. It
never files cards, flips status, or mutates the deck. Any generalization
card it identifies must be filed via a subsequent `Skill(create-card)`.
N = $ARGUMENTS (default 10 if not provided).
## Step 1 — Gather recent closures
```bash
# Read the last N done cards sorted by closed_at
goc --status done --json 2>/dev/null | \
python3 -c "
import json, sys
cards = json.load(sys.stdin)
closed = [c for c in cards if c.get('closed_at')]
closed.sort(key=lambda c: c.get('closed_at', ''), reverse
