Answers questions about how the code works from the knowledge graphs first (code-review-graph, then graphify, then dev-graph) and opens source files only where the graphs point. Use when the user says "how does X work?", "where is Y handled?", "why is this weird?", "walk me through Z", or asks any question about the structure, flow or history of code in this repo.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Step 0: preflight 1. Run `lfg graphs ensure`. If it exits non-zero, stop and show its output. Continue on a stale graph only if the user typed `--allow-stale`. 2. Run `lfg run path`. If a run exists, note it (you may cite `01-brief.md` / `02-design.md`); if not, carry on without one. 3. Set `G="$(lfg repo graph)"` (the graph in the main checkout, shared by every branch and worktree). ## Steps Climb this ladder and stop at the first rung that answers the question. 1. **code-review-graph** (MCP): `get_minimal_context_tool` for the topic. If the symbol is named, `query_graph_tool` (`callers_of`, `callees_of`, `imports_of`) and `semantic_search_nodes_tool` to locate it. Enough? Answer. 2. **graphify** (Bash), for concepts, rationale and organisation: - `graphify query "<question>" --graph $G` - `graphify explain "<concept>" --graph $G` - `graphify path "<A>" "<B>" --graph $G` for "how does A reach B". NOTE/WHY/HACK rationale nodes answer "why is this weird?". 3. **dev-graph** (Omnigraph MCP): `Decision`, `Principle`, `Invariant`, `Gap`, `Learning` nodes for the touched `Component`. These explain *why* a design is the way it is. …

How to install
mdr add varun-singhh/lfg/explain@sha256:388ab0028349b2f9The line at the top of this page pins the label git:20261015.6b3a06b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
