Plugins and tools for people who work with AI, not just use it.
We build opinionated tools born from real workflows: writing systems, domain-specific copilots, long-form fiction engines. Everything here started as a solution to an actual problem, got tested in production, and shipped when it worked.
| Plugin | What it does |
|---|---|
| voice-first-writing | Captures your authentic voice and produces content that sounds like you. Self-updating voice guide, 5-step drafting workflow, platform format guides. |
| longform-plugin | Maintains coherence across novel-length fiction. Continuity tracking, thread management, foreshadowing systems, living documents. |
| coldchain-qa-plugin | QA automation for pharmaceutical cold chain. Deviation investigation, excursion triage, root cause analysis, CAPA management. |
Add the marketplace, then install what you need:
/plugin marketplace add third-order-labs/claude-plugins
/plugin install voice-first-writing@third-order-labs-plugins
All plugins work with both Claude Code and Cowork.
Third Order Labs is built by Ian Jones. The name reflects how we think: first-order effects are obvious, second-order effects are predictable, third-order effects are where things get interesting.
