README
Thoth
"Thoth, scribe of the gods, keeper of knowledge."
Long-term memory for Claude Code agents. Rust-native, code-aware, zero API required.

What it is
Thoth gives a Claude Code agent persistent, disciplined memory of a codebase. It parses source with tree-sitter, builds a symbol graph (calls, imports, extends, references), indexes everything with BM25 (tantivy) and RRF fusion, and enforces a "recall before write" gate so the agent consults memory before mutating code.
Three binaries:
thoth— CLI: setup, index, query, eval, memory ops.thoth-mcp— MCP stdio server (41 tools, 3 prompts, 2 resources).thoth-gate— PreToolUse hook: blocks writes without prior recall.
`thoth setup` wires everything — hooks, MCP server, skills, config — in one command.
Nothing leaves your machine unless you opt in.
