Ops: Monitor Errors Skill

Ops: Monitor Errors

Monitor Sentry for errors in the application.

Argument: $ARGUMENTS — project (frontend, backend, all; default: all) and optional time range (default: 1h)

Discovery

Discover Sentry configuration from:

.sentryclirc — org and project names
.env.* files — EXPO_PUBLIC_SENTRY_DSN for DSN
package.json — @sentry/react-native (frontend) or @sentry/node (backend) for project type

Sentry CLI

List Unresolved Issues

sentry-cli issues list \
  --org {org} \
  --project {project}

Filter by Environment

sentry-cli issues list \
  --org {org} \
  --project {project} \
  --query "is:unresolved environment:{env}"

Post-Deploy Check (new issues since deploy)

sentry-cli issues list \
  --org {org} \
  --project {project} \
  --query "is:unresolved firstSeen:-{time}"

Where {time} is a Sentry duration like 1h, 30m, 24h.

Sentry API (Fallback)

If sentry-cli is not installed or not authenticated, use the API directly:

List Unresolved Issues

curl -sf "https://sentry.io/api/0/projects/{org}/{project}/issues/?query=is:unresolved&sort=date" \
  -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" | \
  jq '.[] | {id: .id, title: .title, count: .count, userCount: .userCount, firstSeen: .firstSeen, lastSeen: .lastSeen}'

Filter by Environment

curl -sf "https://sentry.io/api/0/projects/{org}/{project}/issues/?query=is:unresolved+environment:{env}&sort=date" \
  -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" | \
  jq '.[] | {id: .id, title: .title, count: .count, userCount: .userCount}'

Post-Deploy Workflow

After any deployment:

Wait 5 minutes for errors to surface
Check for new unresolved issues in the deployed environment
Assess severity: are these new regressions or pre-existing?
Report findings with severity assessment

Output Format

Report errors as a table:

| Issue ID | Title | Events | Users | First Seen | Severity | |----------|-------|--------|-------|------------|----------| | 12345 | TypeError: Cannot read property 'name' | 42 | 15 | 5m ago | HIGH | | 12346 | Network request failed | 3 | 2 | 2h ago | MEDIUM |

Severity Classification

| Severity | Criteria | |----------|----------| | CRITICAL | > 100 events or > 50 users in last hour | | HIGH | > 10 events or > 5 users, appeared after deploy | | MEDIUM | Recurring issue, < 10 events | | LOW | < 3 events, no user impact |

Include summary: total unresolved issues, new since last deploy, and recommendation (proceed / investigate / rollback).
