CodeAlta 0.9.0

CodeAlta

CodeAlta is a terminal workspace for agentic coding. It brings model-provider setup, project navigation, prompt attachments, threaded sessions, delegated work, and trusted local plugins behind the alta command.

CodeAlta is pre-release software. Configuration, screenshots, and extension APIs may change before 1.0.

🚀 Install

Install .NET 10, then install the CodeAlta global tool:

dotnet tool install -g CodeAlta
alta

Update an existing installation with:

dotnet tool update -g CodeAlta

On first launch, CodeAlta creates ~/.alta/config.toml. If no provider is enabled yet, the Model Providers dialog opens so you can configure Codex, Copilot, OpenAI/Azure OpenAI APIs, Anthropic, Gemini/Vertex, or custom endpoints.

✨ What it gives you

• Keyboard-first terminal workspace: tabs, prompt editor, project sidebar, command discovery, model selectors, context status, and inspectable timeline cards stay in one TUI.
• Provider-neutral model setup: configure hosted APIs, subscription-backed Codex/Copilot, cloud providers, and compatible endpoints with the same provider workflow.
• Context-aware prompts: attach files and folders with @, paste images when the selected model supports them, and inspect what context was sent.
• Threaded agent sessions: keep project-scoped history, reopen sessions, queue prompts on busy threads, steer running work where supported, and compact long local-runtime conversations.
• Actionable operations: model/provider tests, startup config recovery, usage details, logs, modified-file summaries, and tool input/output dialogs are built into the workspace.
• Trusted local extension points: source plugins, Agent Skills-compatible skill folders, and the in-session alta live tool let you automate local workflows while keeping provenance visible.
