Can I use this for technical documentation?

While primarily for PRDs, it is excellent for technical specs as it includes sections for technical considerations, constraints, and Given/When/Then acceptance criteria.

How does the Feature Spec skill prevent scope creep?

The skill mandates the definition of 'Non-Goals' and uses the MoSCoW framework to prioritize requirements, ensuring the team remains focused on the minimum viable version of a feature.

What kind of success metrics does it suggest?

It helps define both leading indicators, like adoption and activation rates, and lagging indicators, such as retention impact and revenue growth.

Does it support agile user story formats?

Yes, it follows the standard 'As a [user], I want [capability] so that [benefit]' format and adheres to the INVEST principles for high-quality stories.
