runecho

Deterministic symbol oracle over a locally built index of the repo: whether a symbol exists, what a file declares, and what changed structurally since the last snapshot. Ships with a PreToolUse guard that stops an Edit/Write referencing a function, constant or type the repo does not declare, before the write lands. No LLM, no API keys, no network — the same code produces the same answer. Parsers for Go, Python, JS/TS, Rust, Ruby and shell. `bash install.sh`
