Nexrall Code for VS Code
Nexrall Code is an AI coding agent embedded directly in Visual Studio Code — the same autonomous agent that powers Fullstack Agent Coding, exposed as an editor extension.
Install
Search "Nexrall Code" in the Extensions view (⇧⌘X on macOS, Ctrl+Shift+X on Windows/Linux), or run:
sh
code --install-extension NexrallCode.nexrall-code-vscodeWhat it can do
- Read your workspace — semantic navigation (go-to-definition, find-references, hover types) via the language server, not just text search.
- Multi-file edits — targeted changes across as many files as a task needs, applied atomically.
- Run commands — a real terminal, including multi-line scripts and heredocs.
- Live diagnostics — reads the editor's actual error/warning state, not a stale snapshot.
- Agent loop — plans, edits, runs, observes the result, and continues automatically for as many turns as the task needs.
Modes
- Auto — the agent edits files directly.
- Ask — the agent answers questions and explains code without editing anything.
- Plan — the agent proposes an approach without writing any files; every write tool is hard-blocked in this mode, not just discouraged by instruction.
Model tiers
Pick a tier from the model menu:
| Tier | Best for |
|---|---|
| Turbo | Fast, default — everyday coding. |
| Pro | Most capable reasoning for complex, multi-step work. |
| Ultra | Maximum power, 1M-token context, adaptive deep thinking. |
See Model tiers for more detail.
Safety guardrails
Nexrall Code refuses or double-checks a few classes of action automatically:
- Destructive commands — irreversible operations (force-pushing, dropping a database table,
terraform destroy) require explicit confirmation, even if they'd otherwise match an auto-approved pattern. - Silent code loss — an edit that would drop existing code behind a placeholder comment like
// rest unchangedis refused outright. - Test-integrity — weakening a test to make it pass (deleting an assertion, adding
.skip) is flagged, not silently accepted as "done."
Updates
The extension checks for updates automatically and shows a badge when a new version is available — no manual "check for updates" step needed.
Plugins
Nexrall Code supports installable plugins (commands, agents, hooks) — see Plugins.
