Extract a Skill from a Session

The most valuable patterns are the ones you've just used successfully — they're concrete, fresh, and tested. This skill is the discipline of capturing them before context fades.

When to use

• You just finished a non-trivial task and the approach was good.
• You found yourself re-explaining the same workflow to a teammate twice.
• You hit a problem, found the way through, and wrote a Slack message about it (that message is the seed).
• A senior engineer walked you through a process you'd want to repeat.
• After an incident, the response process worked well and should be reusable.

When NOT to use

• One-off problem unlikely to recur.
• Domain-specific knowledge that doesn't generalize.
• The pattern is already in an existing skill — improve that one instead.
• You're not sure you did it right yet — wait until you've validated.
