Weekly newsletters that document your codebase
You could ask an AI about your codebase — Abstractions just doesn't wait for you to. Weekly digests of architectural changes, system relationships, and patterns, delivered automatically.

Idempotency keys moved to Redis
Payment retries are now deduplicated at the gateway rather than in the database. The team moved idempotency keys into Redis to close the race condition surfaced during the March incident.
Why it matters
Duplicate charges were possible when a client retried before the first write committed. Centralising the key check removes that window without adding a second round-trip to Postgres.

The faster you ship, the harder it becomes for everyone on the team to understand how everything fits together.
New hires can't keep up
PRs merge faster than onboarding docs can keep pace. New engineers spend weeks just building a mental model.
Senior engineers start forgetting
How did we handle auth again? Which service owns rate-limiting? Context gets lost as codebases evolve.
Decisions get made without history
Why did we pick this pattern? What trade-offs did we consider? That reasoning lives in someone's head — or nowhere at all.
Solve context debt with the right tools
Keep your entire team aligned with your codebase. Automatic, always fresh.
Understand the why, not just the what
Newsletters explain the decisions, trade-offs, and reasoning behind your code — not just what it does, but why it was built that way.
Onboard engineers in days, not weeks
New hires get instant access to an AI-generated guide to your codebase. Understand patterns, decisions, and dependencies on day one.
Doesn't wait for you to ask
You could ask an AI assistant about your codebase — but that only surfaces what you think to ask about. Abstractions watches your repos, figures out a topic on its own, and tells you before you knew to ask.
