SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? After an outage, teams struggle to communicate with customers honestly: they either hide behind passive voice, bury bad news about data loss, name individual engineers, or make promises that never land. This Skill provides a proven structure and honesty rules for writing postmortems that preserve customer trust. ## Core Features & Use Cases - Structured Postmortem Template: Covers what happened in customer terms, UTC timeline with local notes, specific impact, honest root cause, remediation, and dated preventive changes. - Honesty and Tone Rules: Enforces active voice ("we deployed a change that..."), forbids naming individuals, and requires data loss or exposure to be disclosed in the first paragraph. - Commitment Discipline: Limits commitments to work already scheduled with an owner, and blocks overstated fixes or "it cannot happen again" promises. - Use Case: After a two-hour API outage that delayed customer webhook deliveries, use this Skill to draft a status-page postmortem that states the data delay upfront, explains the cause without internal detail, and lists only confirmed follow-up work. ## Quick Start Write a customer-facing postmortem for yesterday's 90-minute checkout outage that delayed order confirmation emails.

FAQPage Schema
How do I write a customer-facing postmortem after an outage?▼

Structure it as: what happened in customer terms, start and end times in UTC with a local note, who and what was affected specifically, the honest cause without internal detail, what was done, and dated changes to prevent recurrence. Use active voice throughout.

What should a public incident postmortem include?▼

Include the customer-visible impact, a confirmed timeline, an honest cause stated in active voice, remediation steps taken, and only preventive commitments that are already scheduled with an owner. Never overstate the fix or promise it cannot happen again.

Should a postmortem disclose data loss to customers?▼

Yes. If data was lost, exposed, or delayed, state it in the first paragraph. Burying data impact turns an outage into a trust incident, and the information always surfaces later.

Why should postmortems avoid naming individual engineers?▼

Naming an individual is a hostile act and misrepresents the failure, which belongs to the system. Say "we deployed a change that..." instead of attributing blame to a person or using passive voice like "an issue occurred."

When should you not publish a customer postmortem?▼

Do not publish before the incident timeline is confirmed. Also avoid publishing commitments that are not already scheduled with an owner, since a postmortem promise that does not land is worse than making none.
