codemble 0.3.1

A learning game that turns the code AI wrote for you into a galaxy you light up by understanding it.

Codemble

Turn AI-built code into a galaxy you actually understand.

Codemble is a local-first learning game for projects built with Claude Code, Codex, and other coding agents. It maps real parser evidence into a 3D galaxy, then lights each region only after you prove you understand it.

Your project · Your key · Your machine · No invented structure

Quick start · Learning loop · Documentation · Test Codemble

[!IMPORTANT] Codemble is in its Phase 1 tester release. It maps Python, JavaScript, TypeScript, and mixed projects in one parser-proven galaxy, installable straight from PyPI with an in-app project picker. The technical release is complete; unaided learner runs are the evidence still being collected. Try the ten-minute tester loop.

Quick start

uvx codemble            # or: pipx install codemble && codemble

Codemble opens your browser — pick your project folder there. To skip the picker, pass a path: codemble ./your-ai-built-project.

The wheel already contains the web app, so Node.js is not required. No API key is needed for the galaxy, source viewer, language Lens, checks, lighting, or saved progress. Add your own Anthropic or OpenAI key only if you want grounded prose explanations:

export ANTHROPIC_API_KEY=sk-ant-...   # or OPENAI_API_KEY=sk-...

How the learning loop works

Step	What Codemble does	What you gain
1. Chart	Parses your project without running its code or package scripts	A deterministic map made from source evidence
2. Navigate	Guides you from galaxy → system → study on scripted camera rails	Orientation without getting lost in free flight
3. Study	Shows the real source, exact line numbers, neighbors, and parser-detected language idioms	Context tied to code you can inspect
4. Prove	Generates and scores checks from the graph—never from the model	A region lights only when understanding is demonstrated
5. Return	Saves progress locally; changing one file re-dims only its module	A living map that stays honest as the project changes

No XP. No streaks. No leaderboard. The visible reward is the useful one: more of your own code becomes a sky you understand.

Read the galaxy

In the galaxy	In your project
A star system	One source module
A planet	A function or class
The Home system	The selected parser-ranked entrypoint
A route or edge	An import or call; approximate calls are labeled possible
Size	Lines of code
Brightness	Structural centrality
Dim → lit	Not yet proven → understood

Python-only, JavaScript-only, TypeScript-only, and mixed projects share the same graph contract. Language focus changes only what you are looking at; it never changes coordinates, progress, or parser truth.

Honest by construction

Codemble is built for learners who may not yet be able to spot a confident mistake. Accuracy therefore outranks spectacle:

• Structure, entrypoints, concepts, imports, and calls come from parsers.
• Every explanation points to a real file:line and may name only supplied identifiers and relationships.
• Language Lens notes appear only where a parser detected the construct.
• Check answers come from the graph, never an LLM.
• Approximate relationships stay visibly uncertain.
• Provider output that fails grounding validation is withheld instead of being softened into a guess.

Read the full correctness contract. A wrong explanation is a highest-severity bug—report it without mercy.

Local-first, with an explicit AI boundary

Stays on your machine	Leaves only when you ask
Project discovery and parsing	The bounded Study context sent to your configured provider
Graph, language Lens, and checks	A request triggered only when you open Study
Local server and packaged web app	Nothing in the background
Progress and explanation cache in ~/.codemble/	No accounts, telemetry, or Codemble cloud

No key? Codemble remains a complete parser-backed map and learning game; only the optional prose narration is unavailable.

Boundaries that keep the map truthful

• Supported source: Python 3.11+, JavaScript/JSX, TypeScript/TSX, and mixed projects. Unsupported languages stay outside the graph rather than being guessed.
• Scale: above roughly 300 supported source files, choose a subdirectory — the in-app picker prompts for the scope, or pass codemble --path ./project/subdirectory.
• Ambiguous Home: choose a parser-ranked entrypoint in the app or pass --entrypoint NODE_ID.
• Broken source: syntax errors remain visible; Codemble maps safe partial evidence instead of crashing or inventing the missing structure.
• Rendering: WebGL is required. There is intentionally no misleading 2D fallback in this release.

Help test the release

The most valuable contribution right now is not a feature request. It is a first run on a real AI-built project:

1. Follow the ten-minute tester guide.
2. Light at least one system.
3. Report confusion verbatim—never paste private source or API keys.

Roadmap

Horizon	Work
Now	Collect unaided first-run evidence on the current release across supported project types
Next	Go, Rust, and Java adapters; level-of-detail rendering for larger repositories
Later	Read-only share links, new quest types, and the coordinated public launch

The public roadmap separates shipped work from planned work. Milestones move only when their acceptance evidence exists.
