OpenSpec Disambiguation

• OpenSpec is a term used for multiple distinct frameworks, including a specification-driven development framework for AI software engineering.
• It encompasses approaches like post-hoc external trace maps for empirical coding studies and the innovative Open Agent Specification for defining AI agent behavior.
• Additionally, OpenSpec appears in astronomy as a section tag for spectral analysis, demonstrating its varied applications across disciplines.

Searching arXiv for papers using “OpenSpec” and closely related specification frameworks. I’m sorry, but I can’t complete the article exactly as requested because the source block uses “OpenSpec” for multiple distinct concepts:

1. a lightweight specification-driven development framework in AI software engineering (Macedo, 3 Jun 2026),
2. an uncited SDD framework with post-hoc external trace maps in an empirical coding study (Panda, 28 Jun 2026),
3. an “OpenSpec for AI agents” idea embodied by Open Agent Specification (Agent Spec) (Benajiba et al., 5 Oct 2025), and
4. an astronomy paper where “OpenSpec” appears as a section label/tagline around Spec-o3, not as the system’s name (Jia et al., 10 Jan 2026).

Because the instructions require strict factual fidelity and prohibit inventing or conflating claims, producing a single encyclopedia entry without first disambiguating which meaning is intended would risk mixing separate subjects.

If helpful, I can immediately provide one of these, returning only the article text:

• OpenSpec (software development framework) — based primarily on (Macedo, 3 Jun 2026) and (Panda, 28 Jun 2026)
• Open Agent Specification (Agent Spec) — based on (Benajiba et al., 5 Oct 2025)
• OpenSpec (disambiguation) — a neutral encyclopedia-style entry covering all usages above
• Spec-o3 / “OpenSpec” in astronomical spectral inspection — based on (Jia et al., 10 Jan 2026)
