| name | ops-observe |
| description | Read the system's own story before you touch it — logs, metrics, health, recent deploys, error rates. Triggers on "why is it slow", "what's happening on the server", "check the logs", "is it healthy", and as the first step of `ops-incident`. Read-only toward the system: it gathers evidence and files findings, it never mutates the box. |

Observe — let the system tell you what's wrong
Before any theory, gather what the system already knows about itself. Most diagnoses are sitting in the
logs and the last deploy; guessing skips past them. This skill is read-only toward the system —
observing is how you stay the advisor instead of becoming the actor.
Check .mc/env first, so you read the right box with the right care.
The five reads
| What | Where to look |
|---|
| Logs | docker compose logs --since 15m, journalctl -u <svc> --since "15 min ago", kubectl logs <pod> --tail=200 |
| Resources | top / htop, df -h (disk), free -m (memory), docker stats, open FDs — is anything pinned at 100%? |
| Health | curl -sS localhost/health (and /ready) — does the app say it's up, and do its dependencies answer? |
| Recent deploys | git log --oneline -5 on the deployed rev — what changed just before this started? Usually the answer is here. |
| Error rate | the error tracker, or grep the logs for the error over time — is it spiking, flat, or already falling? |
Start with recent deploys: correlation with a deploy time is the single fastest lead. "It broke at
14:00, we shipped at 13:58" closes more incidents than any log grep.
Read broad, then narrow
- Is the process even up? (health,
ps, pod status)
- Is a resource exhausted? (a full disk and out-of-memory are the two most common silent killers)
- What do the logs at the failure time say? (grep the window, not the whole file)
- What changed just before? (a deploy, a config, traffic, a dependency)
The predicate rule — no observability is itself a finding
If the project has no observability at all — no logs you can query, no health endpoint, no metrics — that
is a high finding. File it before proceeding. You are flying blind, and that blindness is the first
thing to fix, not something to work around. Write it under the findings path per docs/FINDING-SPEC.md
(severity high, status open): a system you cannot observe is a system you cannot safely operate.
Hand off what you found
Observation feeds the next skill: a spike after a deploy → ops-rollback; an active outage → ops-incident
with the timeline seeded from what you saw; a resource trend with no incident yet → a finding for later.
Report numbers and log lines, never impressions — "disk 100% on /var since 13:40", not "seems unhealthy".
Pairs with ops-incident (which opens by observing) and ops-env-map (know the box first). Credits: the
"read the telemetry before you theorize" discipline from standard SRE monitoring practice.
