+description:
+  short: >-
+    Bridges a Graphify knowledge graph into agent development workflows:
+    blast radius, context packs, drift, and graph-first debugging.
+  long: >-
+    A zero-dependency Python bridge plus eleven Claude Code skills that make an
+    existing code graph usable during real work. It computes the blast radius of
+    a change by bidirectional traversal, renders token-budgeted context packs for
+    subagents, answers reverse-dependency questions, diffs two graph snapshots to
+    surface architecture drift, checks whether the graph is still current, and
+    flags scope creep by comparing touched files against the planned set. It reads
+    graph.json directly rather than importing the tool that produced it, so a
+    schema change fails loudly instead of quietly misleading a plan.
+
+problem: >-
+  A coding agent plans, debugs, and reviews from whatever files it happened to
+  read, with no view of what a change actually reaches, so blast radius is
+  guessed and architectural drift is noticed only after it ships.
