Workflows That Write Code

CodingAgentStep is an autonomous code-generation step type for workflows. Docker-sandboxed, multi-language, and fully auditable — it clones your repo, writes code, runs tests, and produces a pull request with a clear diff.

How It Works

CodingAgentStep in the workflow builder

Define a natural-language task, pick a model (Claude Sonnet 4.6 recommended), and configure sandbox settings. The agent clones your repo, writes code, runs tests, and creates a pull request — all inside a single workflow step.

  • Natural-language task description
  • Model selection per step
  • Docker sandbox isolation
  • Automatic PR creation

Docker Sandbox

Isolated execution in every run

Every execution runs in an isolated Docker container. No access to host filesystem or network. Configurable memory (up to 2 GB), CPU time limits, and execution timeout. All file changes are captured and committed.

  • Isolated filesystem per execution
  • No network access to host
  • Configurable resource limits
  • Full audit trail of changes

Real-World Use Cases

From test generation to framework migrations

Auto-generate unit tests for untested modules, create documentation from code, migrate between frameworks, generate boilerplate from specs. Each execution produces a PR with a clear diff.

  • Test generation and coverage improvement
  • Documentation sync with code changes
  • Framework and dependency upgrades
  • Boilerplate generation from specifications

How It Works

Three steps to autonomous code generation

1

Add CodingAgentStep

Add a coding agent step to any workflow. Describe the task in natural language — "write unit tests for the auth module" or "migrate the API client from v2 to v3."

2

Configure sandbox

Set the model, memory limits, timeout, and target repository. The agent spins up a Docker container, clones the repo, and begins execution in full isolation.

3

Review output

The agent produces a pull request with code changes, test results, and execution traces. Review the diff, check the test output, and merge when ready.
