SpecForge is a platform for authoring formal specifications using the Lilo temporal specification language, providing a VSCode extension with syntax highlighting, type-checking, and satisfiability analysis for hybrid systems.
The author describes building Sponsio, an open-source deterministic enforcement layer for LLM agents that prevents 'legal but wrong' actions by evaluating tool calls against YAML contracts with temporal logic, addressing a gap in prompt engineering.
This paper proposes techniques that combine formal methods (Linear Temporal Logic) with LLMs for auditing, monitoring, and intervening in AI systems to ensure compliance with behavioral constraints, showing that even small-model labelers can match frontier LLM judges in detecting violations.
An introduction to using TLA+ with LLMs like Claude to write formal specifications, showing how LLMs can help with syntax while focusing on correctness.
This paper proposes Embedding Temporal Logic (ETL), a temporal logic that monitors perception-based autonomous systems directly in learned embedding spaces, enabling specification of high-level perceptual concepts and achieving strong empirical agreement with ground-truth semantics.
Explains the concept of possibility properties in formal methods, complementing safety and liveness, and discusses their use in specification and model checking.
