    adal Repository Guidelines

    If you are AdaL, this is source code, from your CLI to backend in deep_research, to tools, to AdaLFlow.

    Your goal is to self-evolve into the best coding, engineering, and research agent in the world.

    Your differentiators include:

    1. 1.simplicity UI/UX without adding too many buttons or frictions.
    2. 2.agentic-first approaches that start from first principles.
    3. 3.senior-engineer workflows that improve the product while doing the work.

    Project Structure & Module Organization

    adal-cli/ React terminal frontend; spawns the backend automatically.

    Build Your Agents on Top of AdaL.

    Use AdaL headless, through the SDK, or with a meta-agent that helps harness domain-specific worker agents.

    As one of the earliest AdaL users, I’ve used it for months to solve hard and daunting tasks smoothly. We greatly enjoy the flexibility of model switching — AdaL plays the role of both designer and engineer on our team.

    AdaL stays oriented in our codebase. It helps us move through boilerplate and edge-case-heavy contract logic without turning the work into a week-long slog.
    Debamitro Chakraborti

    AdaL stayed stable across releases and kept adding useful features like model switching, multiple providers, and sub-agents. I’ve used it for full-stack platforms, iOS prototypes, compilers, and a command-line coding agent I use regularly.

    AdaL feels like a careful engineering partner. It explains its approach, shares useful context, and gives implementation insights that make development more enjoyable. Its deep research mode is especially valuable for understanding unfamiliar domains before building.

    As a small team of 2 developers, using AdaL has allowed us to increase our work capacity and move quickly. The ability to choose between multiple frontier models, easily keep context through multiple sessions, and knowing my data is private is what keeps me using AdaL.

    AdaL feels fundamentally different from other AI coding agents. It understands intent well, orchestrates tasks effectively through sub-agents, and delivers responses noticeably faster in complex workflows. It was the only agent that successfully navigated multiple roadblocks autonomously and completed the task end-to-end.
    Mihai Chindris

    Mihai Chindris

    Engineer, Siemens

    I chose AdaL because it was the only agent that truly grasped the engineering problem, not just the last prompt. It stayed focused across the entire codebase, caught edge cases I would have overlooked, and delivered something I was genuinely proud to ship. It even helped me submit a hackathon project on a tight deadline, which I couldn't have accomplished alone. If you've been disappointed by agents that generate code that doesn't hold together, AdaL is genuinely different.

    I use AdaL to prototype research papers - the stage where the spec is half-formed, the codebase doesn't exist yet, and most AI tools collapse. AdaL holds up. It lets me take a paper-stage idea to a working experiment in hours instead of a week, which means I kill bad hypotheses earlier and put real compute behind the ones that survive. For research velocity, that's the only metric that matters.

    Our Thesis

    The vibe coding crisis is real.

    The crisis is not that AI writes bad code. It is that teams confuse code generation with engineering progress.

    20%
    visible code
    80%
    real engineering work
    Understanding the problem
    Planning architecture
    Making tradeoffs
    Reviewing decisions
    Debugging edge cases
    Maintaining quality

    Agentic engineering brings that 80% back into the workflow. Agents execute with rigor, share long-term memory, and bring humans in for the decisions that shape the system.

    Build Better
    & Faster.

    Stay in control, understand faster, and ship with confidence.
