Axion

Analyze → Plan → Execute → Validate

A deterministic, local-first AI orchestrator for software engineers.

Axion is not a chat interface. It is not autocomplete. It is not “AI magic”.

It is an engineering tool.

What Axion is (and what it is not)

Axion treats Large Language Models as non-deterministic execution engines that must operate inside a strict, auditable pipeline.

Instead of asking an AI “please fix my code”, you force it to:

1. Analyze the real project structure
2. Plan concrete technical steps
3. Execute changes as reviewable diffs
4. Validate results with real tooling

No hidden prompts.
No blind edits.
No guessing.

Why this project exists

Most AI coding tools optimize for speed of output.

Software engineering optimizes for:

• correctness
• predictability
• debuggability
• long-term maintainability

That mismatch causes real problems:

• Code is generated without understanding the project
• Developers approve changes they don’t fully understand
• Bugs are pushed faster, not fewer

Axion exists to slow AI down and force it to behave like a junior engineer working under strict supervision.

The core difference

Aspect	Typical AI Tools	Axion
Interaction	Chat / Autocomplete	Structured pipeline
Control	Implicit	Explicit and reviewable
Output	Raw code	Unified diffs
Context	Prompt-limited	Project-aware
Validation	Manual	Automated
Philosophy	“Trust the model”	“Trust the process”

Design principles

Local-first
Your code stays on your machine. Axion runs locally and only sends what is strictly necessary to the model.

No magic
Every decision is logged. Every step is inspectable. Every change is explicit.

Tool-driven
The AI uses tools (AST parsing, tests, linters). It does not replace them.

Human-in-the-loop
Nothing is applied without your approval.

What Axion can do today

• 🔍 Structural code reviews
  Detect bugs, architectural risks, performance issues, and security problems.

• 🧭 Technical planning
  Generate step-by-step implementation plans in Markdown.

• 🧩 Diff-based solutions
  Propose changes as standard unified diffs — no direct file mutation.

• 🧪 Local validation
  Run tests and tooling before applying changes.

• 🔌 Extensible architecture
  Plugin system for custom tools and workflows.

• 🤖 Model agnostic
  Works with OpenAI, Anthropic, Ollama, and any LiteLLM-compatible provider.

Installation

pip install axionflow

Python 3.10+ required.

---

Basic usage

Initialize / Review a project

axion review .

Generate a technical plan

axion plan "Refactor authentication to use JWT with refresh tokens"

Solve a concrete problem

axion solve "Fix silent failures in the reasoning engine error handling"

All commands follow the same pipeline:

Analyze → Plan → Execute → Validate

---

Extending Axion

Axion is designed to be extended by engineers.

• Custom tools
• Custom validators
• Custom reasoning steps

See the Plugin Development Guide.

---

Contributing

Axion is not looking for volume. It is looking for engineering-quality contributions.

If you care about:

• clean abstractions
• predictable systems
• readable diffs
• testable behavior

You’ll fit right in.

See CONTRIBUTING.md.
