description	Monitor health across configured service endpoints, CI pipelines, and critical issues. Automatically invoked during session-start when ecosystem-health is enabled in Session Config.

Ecosystem Health Check

Platform-native (CC 2.1.105+)

This skill's watcher is registered as a plugin monitor via .claude-plugin/plugin.json's experimental.monitors reference to monitors/monitors.json. Each session that loads this plugin auto-starts the watcher in the background (see scripts/lib/ecosystem-health.mjs). Each NDJSON stdout line from the watcher becomes a <task_notification> event Claude sees mid-session.

For harness < 2.1.105 (no monitor support), the skill's manual probes documented below serve as the fallback path.

Session Config Fields Used

This skill reads from the project's ## Session Config section in the platform instruction file:

• health-endpoints — list of {name, url} objects for service health checks
• cross-repos — list of related repositories for critical issue scanning

Both fields are optional. The skill degrades gracefully when either is missing. On Codex this means AGENTS.md; on Claude/Cursor it means CLAUDE.md.

Service Health

Read the health-endpoints field from Session Config. If not configured or empty, print:

No health endpoints configured in Session Config. Add health-endpoints to enable service monitoring.

and skip this section.

Otherwise, for each configured endpoint, run a health check:

# Example health-endpoints config:
#   health-endpoints:
#     - name: API
#       url: https://api.example.com/health
#     - name: Worker
#       url: http://worker:8080/healthz
#     - name: Dashboard
#       url: http://localhost:3000/api/health

# For EACH endpoint in health-endpoints, run:
# NAME=<name> URL=<url>
curl -s --max-time 6 -w '\nHTTP_STATUS:%{http_code}' "$URL" 2>/dev/null \
  | python3 -c "
import sys, json
raw = sys.stdin.read()
body, _, status_line = raw.rpartition('\nHTTP_STATUS:')
http_code = int(status_line.strip() or '0')
status = None
try:
    d = json.loads(body)
    if isinstance(d, dict) and 'status' in d:
        bs = str(d['status']).lower()
        status = 'DEGRADED' if bs == 'degraded' else ('OK' if bs in ('ok', 'healthy', 'up') else 'DOWN')
except Exception:
    pass
if status is None:
    status = 'OK' if 200 <= http_code < 400 else 'DOWN'
print(f'\$NAME: {status}')
" 2>/dev/null || echo "\$NAME: unreachable"

Generate the check commands dynamically from the config — do not hardcode any service names or URLs.

Critical Issues Across Projects

Read the cross-repos field from Session Config. If not configured or empty, print:

No cross-repos configured in Session Config. Add cross-repos to enable cross-project issue scanning.

and skip this section.

Detect VCS

VCS Reference: Detect the VCS platform per the "VCS Auto-Detection" section of the gitlab-ops skill. Use CLI commands per the "Common CLI Commands" section. For cross-project queries, see "Dynamic Project Resolution."

For each cross-repo, query critical issues

Using the detected VCS CLI (per gitlab-ops "Common CLI Commands" and "Dynamic Project Resolution" sections):

1. Resolve the project ID or owner/repo slug for each cross-repo
2. Query open issues with priority:critical or priority:high labels (limit 5 per repo)
3. Collect results across all configured repos

CI Pipeline Status

Query the latest pipeline/workflow runs for the current repo using the detected VCS CLI (per gitlab-ops "Common CLI Commands" section). Report the 3 most recent runs.

Report Format

Present as a compact health dashboard. Build the table dynamically from whichever endpoints are configured:

## Ecosystem Health
| Service       | Status            |
|---------------|-------------------|
| <name>        | [OK/DEGRADED/DOWN/unreachable]  |
| ...           | ...               |

Critical issues: [N total across cross-repos]
CI: [green/red/pending]

If no health endpoints are configured, omit the service table entirely. If no cross-repos are configured, omit the critical issues line.

Flag any service that is DOWN or DEGRADED, or any critical issue count > 0 as requiring attention.
