Retrospective Postmortem
Overview
Turn completed or failed work into reusable learning.
This skill exists to reduce repeated mistakes, not to assign blame.
Trigger
Use when:
- a task finished and the team wants to learn from it
- a task failed, thrashed, or took an unexpected path
- a recurring trap or process weakness became visible
Stay Out
Do not use when:
- execution is still actively blocked on basic facts
- the task is mid-flight and the right next move is still direct execution
- there is nothing durable to learn beyond ordinary completion notes
Core Rules
- separate facts, causes, and follow-up changes
- capture what went wrong and what almost went wrong
- identify one or two concrete rules, checks, or habits that would prevent recurrence
- keep the writeup concise enough to be reusable
- record recurring traps in
.superplan/gotchas.md - record process or policy changes in
.superplan/decisions.md
Forbidden Behavior
- blame-oriented writing
- vague lessons like "be more careful"
- rewriting history to make the path look cleaner than it was
- producing a long transcript instead of actionable learning
