# Fulcra Agent Health Enhances [`fulcra-agent-teams`](https://github.com/fulcradynamics/agent-skills). When a team is healed by scheduled reconciles across several machines, the operational questions are *"is anything actually running?"* and *"which host went dark?"* — this skill answers them deterministically. (The digest + role-escalation sweep land here too — A5b.) ## How it works - Every `coord-engine reconcile` writes a small **health shard** (`_coord/health/<host-key>.json`: host, timestamp, engine version, task count, warnings) and prunes shards older than 30 days (age-based GC). - **`coord-engine health <team>`** folds the shards: per-host last-reconcile age, STALE flag (>24h), engine version — exits non-zero when no host is fresh (usable as a monitor probe). - **`coord-engine doctor [team]`** is the local preflight: storage CLI on PATH, File Store reachable, engine version. Run it after install and inside scheduled jobs' self-tests (the parent project's heartbeats failed silently on exactly these). ## Operator digest (A5b) `coord-engine digest <team>` folds the aggregate + presence into the four operator questions: **blocked on you** (`needs:human` tags / tasks assigned to your handle — env `FULCRA_COORD_HUMAN`), **upcoming** (`not_before` within 7 days), **agents** (liveness + open work each), and **stale** (active tasks untouched > 48h). `--store` persists it to `_coord/digests/<date>-<window>.md`, deduped per day+window (morning/evening) — heartbeat-s...
