Chiasmus FAQs

Question 1

What kind of code analysis can Chiasmus perform?

Accepted Answer

Chiasmus uses tree-sitter to build source code call graphs, enabling analyses such as identifying dead code, assessing reachability (e.g., user input to database), calculating impact of changes, detecting cycles, and generating comprehensive code review recipes. It supports TypeScript, JavaScript, Python, Go, and Clojure/ClojureScript.

Question 2

Can I customize Chiasmus for my specific verification needs?

Accepted Answer

Yes, Chiasmus allows users to create and manage custom verification templates using the `chiasmus_craft` tool. This empowers LLMs to design templates with specific problem types, skeleton logic, and slot definitions, tailoring the formal verification process to unique use cases.

Question 3

What is Chiasmus and what problem does it solve?

Accepted Answer

Chiasmus is an MCP server that equips Language Models (LLMs) with formal verification and advanced code analysis capabilities. It solves the challenge of ensuring mathematical certainty and deep structural understanding in software, going beyond what LLMs can achieve alone, especially for complex logic, reachability, and code integrity.

Question 4

How does Chiasmus achieve formal verification for LLMs?

Accepted Answer

Chiasmus integrates the Z3 SMT solver and Tau Prolog to provide mathematical certainty. It translates natural language problems into formal logic specifications using a template-based pipeline, allowing LLMs to verify outcomes rigorously, detect conflicts (e.g., in RBAC), and solve complex constraints (e.g., package dependencies).

Question 5

When should I use Chiasmus over traditional LLM-based code reviews?

Accepted Answer

You should use Chiasmus when correctness is non-negotiable and requires mathematical proof, such as verifying 'all inputs' behavior, detecting conflicts, or ensuring reachability/unreachability across combinatorial spaces. For structural code reasoning like dead code identification or impact analysis, Chiasmus provides formal, exhaustive answers that LLMs cannot guarantee with simple string searches.
