twg-operational-health
Use together with the root twg skill. Exact command grammar comes from live
twg help or twg help describe <path>.
CLI launcher fallback
Run twg <command>. On shell command not found, use $HOME/.local/bin/twg
(macOS/Linux) / $env:LOCALAPPDATA\Programs\twg\bin\twg.exe (PowerShell), then
tell user to add that directory to PATH. Do not treat auth or command errors as
PATH failures.
Use When
- "I'm taking over on-call"
- "Reliability, incident, SEV, or post-incident review readout"
- "Investigate an active incident and find mitigation"
- "Analyze root cause or draft postmortem/PIR learning/action items"
- "Open risks, blockers, overloaded people, operational health"
First Move
Resolve scope, window, anchors, owner/escalation path, status, recency, and
follow-ups. Find the operational anchor before joining relevant surfaces.
Run without --site; TWG inherits the user's pinned Jira/JSM site. Only add a
site override when the user explicitly requests another tenant. Never assume a
vendor-internal incident site.
Evidence Policy
- Rank by impact, urgency, owner clarity, recurrence risk, and actionability; separate live risks from historical mentions.
- Cluster compact incident, PIR, follow-up, runbook, owner, asset, or meeting evidence by service, theme, owner, and recency. Hydrate highest-risk clusters; stop once theme, owner signal, and confidence are clear.
- Separate
working theory,confirmed problem,mitigation, androot cause. Require a causal mechanism for confirmed root cause; a closed record is insufficient. Mark claimsconfirmed,supported,candidate, ormissing evidence; use references for RCA details. - After one correction of a repeated backend, auth, or schema error, report the gap and use remaining evidence instead of nearby aliases or broad inventories.
Recipe Cards
Leadership Reliability Review / On-Call Handoff
Load references/reliability-review.md. Resolve leader, platform, and window;
cluster supported themes, separate cause from mitigation, connect prevention
work, and rank leadership actions. For handoffs, add a first-hour checklist and
escalation map.
Incident Investigation / Mitigation
Use when the incident is active, newly mitigated, or pre-PIR. Anchor on the
incident record, then pull responders, symptoms, impact, recent
deploys/flags/config, topology, alert/log/metric pointers, ownership, runbooks,
and similar incidents. If ticket fields are sparse, probe the four golden-signal
families with bounded follow-ups. See references/incident-investigation.md.
Output a four-signal matrix, hypotheses, confidence, next checks, and mitigation
options; never call a mitigation the root cause without the causal mechanism.
Post-Incident Root Cause / Learning
Use after mitigation/recovery when drafting or evaluating a postmortem/PIR. Pair
the incident with the PIR, linked docs, final comms, remediation PRs, and action
items; cover confirmed mitigation, causal mechanism, 5-why chain, and
detection/response gaps. See references/pir-root-cause.md. Output root cause,
contributing factors, mitigation-versus-cause, and prioritized actions.
Assets / Asset Refresh
Build contributors from project/goal/Jira/PR/doc/activity evidence. Inspect
Assets schema/type metadata before AQL; join people via discovered user-like
attributes such as Calculated user. Rank by contribution centrality plus asset
risk, and report confidence and gaps. See references/assets.md.
Capacity / Staffing / Meetings
For staffing, resolve project/topic/org and identify people by related work, ownership, review influence, docs, and project/goal involvement; check load before recommending. For meetings, query scoped recordings, preview transcripts first, fetch full transcripts only for central ones, then summarize decisions, action items, and gaps.
Output Shape
- Lead with severity, urgency, or recommendation, then owner, status, recency, impact, confidence, and evidence.
- For active investigations, add a four-signal evidence matrix and an incident-to-learning timeline with confirmed problem, mitigation, root-cause status, and prevention action.
- Group patterns across artifacts, give ranked next actions with a suggested owner, and call out data gaps (missing transcripts, no asset match, stale update, ACL/auth gaps, weak ownership).
Anti-Patterns
- Do not fetch every transcript or page body, or treat every incident mention as a live risk.
- Do not wait for chat/comments to label RCA before surfacing directional hypotheses for pre-PIR investigation.
- Do not call mitigation root cause without an established mechanism. Do not treat workflow panels, bot comments, or opaque fields as RCA narrative.
- Do not use keyword matches alone as org ownership — cross-check assignee, service owner, PIR participants, or org-tree membership.
- Do not join Assets by display-name guesses before inspecting schema/type fields, or recommend staffing from activity counts alone.
