Claude Plugin · Free
Anchor
A thinking partner that holds your product's true-north constitution and pressure-tests new feature ideas against it. Not a gatekeeper. You leave each session more convicted or more relieved. Either is a win.
How it works
- SetupFirst use only. Anchor asks three questions and stores your answers as your product's constitution: who specifically is the target user, what winning looks like for them in observable terms, and the one thing the product must do better than anything else.
- ChallengeYou describe a feature in plain language. Anchor interrogates it against the constitution with four questions, then gives a structured reflection: where the feature is aligned, where the tension lives, and a clear verdict.
- IterationThe constitution can be updated, but only as a deliberate act. Anchor slows you down so casual drift doesn't happen. If you're changing the constitution to justify a feature it just challenged, it will name that pattern directly.
The rarest skill in the AI-native product era isn't prompting or shipping speed. It's being able to finish this sentence: we build this, for these people, until it does this one thing better than anyone else.
