# How Will Larson actually uses coding agents

Staff Engineer, CTO at Imprint

**If you take one thing:** `/linear-project-loop`, loops a project to its goal. a software-factory skill that audits a Linear project's RFC and metrics, files missing issues, then works the unblocked ones.

- **Agent:** Claude Code ([source, 2026-09-20](https://lethain.com/software-factory-experiment/))
- **Agent:** Agent Fleet ([source, 2026-09-20](https://lethain.com/software-factory-experiment/))
- **Agent:** Codex ([source, 2026-04-12](https://lethain.com/agents-as-scaffolding/))
- **Model:** GPT 5.4 ([source, 2026-04-12](https://lethain.com/agents-as-scaffolding/))
- **Review:** Same harness reviews first, context cleared; humans after ([source, 2026-06-15](https://lethain.com/revised-rules-of-engineering-leadership/))
- **At once:** five or so projects ([source, 2026-03-11](https://lethain.com/judgment-is-all-you-need/))
- **Harness:** ~10 local workspaces, each with a checkout of every repo, for cross-repo PRs; Agent Fleet for remote work ([source, 2026-09-20](https://lethain.com/software-factory-experiment/))
- **Rules file:** AGENTS.md (156 lines), CLAUDE.md just imports it ([source, 2025-12-25](https://github.com/lethain/workflows/blob/193edc36efdf0c59b2eb0a28d42b346256543ae2/AGENTS.md#L3-L5))

- **MCP servers:** datadog ([source, 2026-09-20](https://lethain.com/software-factory-experiment/))

## In their words

> January: get every engineer onto Claude Code every single day

> let’s roll out an orchestrated harness which internally we call “Agent Fleet”, along the lines of Stripe’s Minions

> generally I can take logs of some recent runs, the agent’s prompt, and some brief instructions, throw them into Codex/Claude, and get a working replacement in a few minutes.

> About a month ago, when I upgraded from GPT 4.1 to GPT 5.4 with high reasoning, I noticed that it got quite good at using the Github MCP to determine the appropriate owners for a given issue

> After I go beyond five or so concurrent projects, I tend to lose track of the necessary work to shepherd those projects to completion
