Theta: Declarative, harness-agnostic configuration standard for AI coding agents

Description and use

**Brief Summary (2‑3 sentences)**
Theta is a declarative, harness‑agnostic configuration standard that lets you describe AI coding agents, their prompts, tools, and memory as reusable, version‑controlled specifications. By turning isolated prompts into composable workflows, Theta makes it easy to coordinate multi‑agent pipelines, add tool‑use stages, and enforce a consistent agent‑state model across projects.

**Value**

• **Repeatable agent workflows** – Write once, run anywhere; the same configuration can be used with different runtimes or orchestration platforms.
• **Cross‑agent coordination** – A single YAML/JSON spec can define how multiple agents exchange data, invoke tools, and share memory, reducing ad‑hoc glue code.
• **Standardisation** – Provides a common schema for agent configuration, facilitating onboarding, code reviews, and auditability across teams.

**Practical Adoption Path**

1. **Prototype** – Fork the repo, explore the example specs, and run the reference interpreter to verify that the declarative format matches your current prompt‑tool setup.
2. **Integration** – Map your existing prompt files, tool wrappers, and memory stores to Theta’s schema; write a thin adapter (typically < 200 LOC) that translates the Theta spec into calls to your chosen LLM provider or orchestration engine.
3. **Validation** – Run the built‑in test suite and add a few integration tests that exercise the end‑to‑end workflow in a sandbox environment.
4. **Documentation & Governance** – Commit the finalized spec to your monorepo, add versioning guidelines, and establish a review process for any future changes to the configuration.

**Production Readiness**

• **Readiness Level:** *Medium* – the project is actively maintained (last update 2026‑06‑22) and suitable for prototypes or internal pipelines, but integration signals are sparse and documentation is limited.
• **Pre‑deployment Checklist:**
• Verify the open‑source license and any third‑party dependencies.
• Assess the issue tracker for unresolved bugs or security concerns.
• Ensure your team can maintain the thin adapter layer and keep the Theta schema in sync with upstream changes.
• Conduct load‑testing if the workflow will be invoked at scale.

If those checks pass, Theta can be rolled out to production for internal tooling or as a foundation for larger, multi‑agent AI services, with the expectation that you’ll monitor upstream updates and be prepared to contribute fixes or enhancements as needed.
