self-assess-arch-healthlisted

# self-assess-arch-health Judge the real stage/wire dependency graph for structural deficiencies. ## Step 0: Settings gate, then the stage_graph prerequisite ``` python3 ${CLAUDE_PLUGIN_ROOT}/scripts/self_assess_cli.py check-enabled --repo <repo_root> --skill self-assess-arch-health ``` Check whether `<output_dir>/stage_graph.json` exists. If it does not, this skill degrades to `Ready-with-gaps` -- write a short `ARCH_HEALTH.md` and `arch_health_summary.json` (empty `findings`, a note that `self-assess-stage-map` has not run) and stop. This is a degrade, not an error: do not fail the skill invocation, just produce a minimal, honest artifact. ## Step 1: Read the full graph Read `stage_graph.json` in full -- never the sampled viewer-format `stage_map.json`. Fan-in and fan-out numbers must come from the complete graph. ## Step 2: Find deficiencies mechanically, then confirm against code Use the graph helpers for the two structural checks that have precise definitions: ``` python3 ${CLAUDE_PLUGIN_ROOT}/scripts/self_assess_cli.py find-cycles --stage-graph <path to stage_graph.json> python3 ${CLAUDE_PLUGIN_ROOT}/scripts/self_assess_cli.py find-god-modules --stage-graph <path to stage_graph.json> ``` `find-cycles` only returns strongly-connected components of size >= 2 (rule `cycle-definition-in-graph`) -- a pair of stages that merely both import a shared third stage is not a cycle, and the Tarjan-based implementation will not report it as one. `find-god-modules` flags sta
