1000-line C program where an LLM can edit the DAG mid-run, but only via a four-verb grammar, and every edit is an auditable event

LLM mutates the workflow DAG mid-run via a constrained four-verb grammar.
Strengths
- •Strict four-verb grammar prevents agent loops while allowing runtime remediation.
- •Single-file C implementation with append-only audit log for replayability.
- •Treats LLM as scheduler peer rather than just another workflow step.
Weaknesses
- •YAML parser supports only a 2-space-indent subset, limiting complex configs.
- •Shells out to curl for HTTP, adding external dependency overhead.

LLM-DAG-UI – A branching conversation interface for Claude
Drag-to-branch is the clear selling point: you can fork any message and pursue alternate prompts while that branch only inherits direct ancestors. The BYOK approach (API key stored in your browser + local Express proxy) keeps it lightweight and safe for a demo, but it's clearly a concept build tied to Claude rather than a multi-model, production-ready tool.
