What is Slo?
Slo is a headless coding harness built for development teams who want the productivity gains of large language models without losing code consistency, conventions, or deterministic outcomes.
The problem Slo solves
As LLM-assisted coding spreads across teams, a familiar problem emerges: each developer's prompt style, each model's output variation, and each session's lost context results in code that looks and behaves differently commit by commit. Conventions drift. Reviews take longer. Onboarding gets harder.
Slo aims at the opposite: structure the relationship between your team and your LLM so outcomes are consistent, predictable, and reviewable.
What Slo ships with
- 100+ vendored skills — covering coding, design, git ops, testing, frontend, CLI, and more.
- 2 first-class workflows — Feature Specifications and Code-Test-Review.
- Opinionated conventions by default — enforced across the entire team.
- Full override capability — every built-in skill or workflow can be replaced.
