Open source · MIT v0.7.0 Claude Code plugin + CLI

Your domain knowledge, kept local. Enforced.

zeno is a productivity tool for the whole product lifecycle. Your rules, prices and past decisions stay in your repo, and the AI checks them before it acts. It guesses less, and you ship faster.

AI forgets your domain

Knowledge lives in chat

Why a price is what it is gets said once, then lost.

Settled things come back

Every session starts fresh. Last month's "no" returns as a new idea.

The AI fills gaps by guessing

It sounds sure, builds it, and you find out later.

How zeno fixes it

  1. 1 Know

    A wiki of decisions, prices, rules and features in each repo. Searched locally, before the AI answers.

  2. 2 Enforce

    A gate weighs each request: do it, do it differently, or push back. Every reason names its source.

  3. 3 Ship

    Checks fail when a rule breaks. Overrides are logged, and zeno proposes better rules from them.

What it caught

Real verdicts. The first three are from zeno's test suite on a sample habit app; the last is from my own products.

Add a $2.99 monthly plan next to the yearly one.

PUSH BACK

  • A recorded decision says yearly only, and it is still active.
  • Monthly subscribers quit after one month at 4× the yearly rate.

Let people share their streak to Instagram.

PUSH BACK

  • Shelved in August: 2 of 40 beta users wanted it.
  • The agreed bar to revisit is 20% asking. Nothing shows it was met.

features/share-streaks · C-04

Clear the old history on app start.

PUSH BACK

  • It is not old: it is every streak the user ever kept.
  • No account and no server copy, so it cannot be restored.

concepts/offline-first · C-12 · C-13

Move every product to Firebase to cut the hosting bill.

PUSH BACK

  • The Postgres apps already cost about $0 on free tiers.
  • Four apps would need their data and money flows rewritten.
