Environment Variables
Every CHAINVET_* environment variable across the analyzer, reports, server, and installer — plus NO_COLOR.
A complete reference of the environment variables Chainvet honors, grouped by where
they take effect.
All AI is opt-in and a no-op by default — with it off, Chainvet runs fully
offline and deterministically. See AI features.
| Variable | Default | Effect |
|---|
CHAINVET_LLM_FALLBACK_PARSER | off | =1 enables AI-assisted parsing when both solc and tree-sitter fail. |
CHAINVET_LLM_REPORT | off | =1 enables LLM review of findings: drop likely false positives, annotate the rest. |
CHAINVET_LLM_ENDPOINT | http://127.0.0.1:11434 | Ollama endpoint. |
CHAINVET_LLM_MODEL | qwen2.5-coder:7b | Ollama model. |
CHAINVET_LLM_TIMEOUT_MS | — | Request timeout. |
CHAINVET_LLM_NUM_PREDICT | — | Token budget per request. |
CHAINVET_LLM_DEBUG | off | =1 enables LLM debug logging. |
These refine the AI fallback parser (each falls back to the general CHAINVET_LLM_*
value when unset):
| Variable | Effect |
|---|
CHAINVET_LLM_FALLBACK_DEBUG | Debug logging for the fallback parser. |
CHAINVET_LLM_FALLBACK_TIMEOUT_MS | Request timeout for the fallback parser. |

CHAINVET_LLM_FALLBACK_MAX_SOURCE_BYTES | Max source bytes sent to the model. |
CHAINVET_LLM_FALLBACK_CHUNK_BYTES | Chunk size when splitting large sources. |
CHAINVET_LLM_FALLBACK_MAX_CHUNKS | Max number of chunks. |
