Codev3

Codev3 is Geoff’s dedicated code generation workspace. It connects to a remote sandbox (coder-host) for code execution, supports full project builds, and can hand off completed work as GitHub pull requests.

​
Key Features

​
Sandbox Execution

Codev3 connects to a remote coder-host sandbox where code is executed in an isolated environment. The sandbox provides:
  • Full filesystem access for project builds
  • Persistent workspaces across chat sessions
  • File management — read, write, list, delete

​
Chain-of-Thought Replay

Every interaction is recorded as SSE (Server-Sent Events) including tool calls, thinking deltas, retries, and errors. On page reload, the workspace replays the full event log to reconstitute the complete chain-of-thought — nothing is lost.

​
GitHub PR Hand-off

When you’re satisfied with the generated code, Codev3 can open a GitHub pull request directly:
  • Reads all non-junk files from the sandbox workspace
  • Pushes them as a single commit on a new branch
  • Opens a PR via StackNet’s GitHub integration
  • Handles up to 50 files, 1MB per file, skipping build artifacts

​
API Routes

​
Architecture

Codev3 dispatches through the agent layer — when contentType: 'agent' is submitted, the request routes to StackNet’s Rust agent core (POST /cpx/agent/run) which handles model selection, tool dispatch, and sandbox management server-side.
