Semble Hooks — semantic code search injected into every Codex prompt

[benediktkraus]

Every prompt you type gets the 5 most relevant code chunks from your project — automatically.

How: Semble indexes your project (<1s, CPU-only, no API key). On every UserPromptSubmit, the hook calls semble search, reranks results (definition boost, noise penalty), and injects them as <relevant-code> into the prompt.

Result: 98% fewer tokens than grep+read. Your AI sees the relevant code BEFORE it starts working.

Also works with Claude Code and Gemini CLI.
