Agentic coding

Agentic coding is what AI-driven software work looks like in 2026.

An agent reads your codebase, runs your tools, writes the change, and shows you the diff. You define what to build, review what comes back, and decide what ships. Nimbalyst is the workspace built around that loop.

Nimbalyst workspace for agentic coding

A clear definition

Agentic coding is software development where an AI agent does the writing and the human directs and reviews. The agent reads files, runs tests, edits code across multiple files, and reports back. The human writes the intent, picks the agent, and reviews the diffs. Coding agents like Claude Code and OpenAI Codex are the engines. The workflow around them is what makes it agentic.

It is different from autocomplete-style AI in an editor. Autocomplete predicts the next token while you type. An agent takes a goal, opens files on its own, makes a sequence of edits, runs commands, and reaches a result. The unit of work is a task, not a keystroke. The unit of review is a diff, not a suggestion.

Why Nimbalyst

What agentic coding needs around the agent

An agent that drives, not a sidebar that suggests

An agent that drives, not a sidebar that suggests

Claude Code or Codex doing the writing, with full read access to the project, the ability to run tests, and a transcript you can scroll through.

Diff review for every change

Diff review for every change

Inline red and green per file. Accept, reject, or refine each change before it lands. The review surface is the editor, not a terminal scroll.

More than one agent at a time

More than one agent at a time

Six or more agents in parallel on a kanban board. Backend changes, frontend tweaks, doc updates, all running side by side without conflict.

Intent in a real document

Intent in a real document

Specs and plans in a WYSIWYG markdown editor instead of long chat messages. The doc is what the agent reads. The doc is also what you keep.

Tasks the agent can pick up

Tasks the agent can pick up

Track features and bugs as tasks with status and links. Agents work through the queue instead of running on one-off prompts.

Pick the engine per task

Pick the engine per task

Claude Code for deep refactors, Codex for quick scaffolding, both in the same project with the same review workflow.

FAQ

Frequently asked questions

What is agentic coding?
Agentic coding is software development driven by an AI agent that can read files, run tools, and write changes across the codebase. The human sets intent and reviews the result. The agent does the writing. Tools like Claude Code and OpenAI Codex are the agents. The workspace around them is what turns a single prompt into a workflow.
What is the difference between vibe coding and agentic coding?
Vibe coding is a style of prompting where you describe what you want and let the agent run. Agentic coding is the broader practice: an agent doing real software work across files, with planning, review, and orchestration around it. You can vibe code with an agent. Agentic coding is what happens when you add structure.
What is the 80% problem in agentic coding?
Agentic coding often gets a feature 80% of the way fast. The last 20% is where context, edge cases, and codebase-specific conventions matter most. Workflows that handle the last 20% well, such as structured specs, parallel agents with focused scopes, and rigorous diff review, are what separate working agentic coding from frustrating agentic coding.
Is agentic coding good?
It depends on the workflow around it. With a clear spec, the right agent for the task, parallel sessions for unrelated work, and file-by-file diff review, it produces real software faster. Without those, it produces plausible-looking changes that need rework. The agent is only part of the answer. The workspace is the other part.
What is the best agent for agentic coding?
Claude Code is strong on deep reasoning, multi-file refactors, and long-running tasks. Codex is fast and good for scaffolding and contained edits. Most agentic coders use both, picking per task. Nimbalyst runs both side by side in the same workspace.
What workspace works best with agentic coding?
Anything that handles parallel sessions, structured specs, and visual diff review. Nimbalyst is built for it: a session kanban for parallel agents, markdown and mockup editors for intent, and inline diff review across every editor type. The desktop and iOS apps are MIT licensed and free for individuals.
