impact from varun-singhh/lfg is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add varun-singhh/lfg/impact@git:20261015.6b3a06bPins git:20261015.6b3a06b in mdr.lock. Pin the fingerprint instead.

Shows the blast radius of the current diff or a named symbol: callers, dependents, affected flows and the tests that cover them, from code-review-graph. Use when the user says "what does this touch?", "blast radius?", "is this safe to change?", "what will my change break?", "who calls X?", or before editing a widely used symbol.
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 (only `--allow-stale` from the user overrides). 2. Run `lfg run path`. If there is a current run, the report goes there; otherwise answer in chat only. ## Steps 1. **Pick the target.** - A symbol was named → that node (find it with `semantic_search_nodes_tool` if the name is ambiguous; ask if still ambiguous). - Nothing named → the working-tree diff: `detect_changes_tool` (changed nodes + risk score). 2. **Start small:** `get_minimal_context_tool` on the target. 3. **Radius:** `get_impact_radius_tool` → direct callers, transitive dependents, node count, communities crossed. 4. **Flows:** `get_affected_flows_tool` → the execution paths that pass through the target. 5. **Tests:** `query_graph_tool` with `tests_for` on every changed or targeted node. List nodes with **no** test. 6. **Governance:** in dev-graph, look up `Invariant`, `Principle` and open `Gap` nodes on the touched `Component`s. 7. **Lane hint:** run `lfg lane --json` and quote its lane and reasons. Do not pick a lane yourself. ## Output ``` …

How to install
mdr add varun-singhh/lfg/impact@sha256:e0d50fa623e833bbThe 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.
