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, and root cause. Require a causal mechanism for confirmed root cause; a closed record is insufficient. Mark claims confirmed, supported, candidate, or missing 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.
• Read build health from bitbucket pipeline query, not pipeline get per pipeline; reserve that for failures whose logs or test reports change the pattern, owner, or action. query lists recent runs only (--limit default 15), so raise it and state the span covered. Hydrate ranked sets through one batched get.

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.
