Code health — health, risk

repowise health

Compute per-file code-health scores from deterministic markers (McCabe complexity, nesting, brain methods, LCOM4 cohesion, god classes, native clone detection, untested hotspots, coverage gradient, git-behavioural risk, and static performance risk), surfaced as three signals: defect risk, maintainability, and performance. Zero LLM calls — pure Python over tree-sitter + git data.

repowise health [PATH] [OPTIONS]

repowise health                                # KPIs + lowest-scoring files
repowise health --file src/api/server.py       # one file in detail
repowise health --module src/api               # restrict to a directory
repowise health --refactoring-targets          # ranked structured plans (impact / effort)
repowise health --generate-code src/api/server.py::handler   # LLM patch for one target
repowise health --trend                        # snapshot history + alerts
repowise health --format json | jq .kpis       # machine-readable

Coverage is ingested separately with repowise coverage add <report>, and repowise health automatically folds in whatever coverage you have already ingested — no flag needed. coverage add also builds a per-test test-to-code map when the report carries contexts (a coverage.py .coverage, or coverage run --contexts=test).

repowise init and repowise update populate the health tables automatically — no separate step needed. repowise status prints a one-line summary:

Health: 7.4 (avg) · 6.2 (hotspots) · 2.1 (worst: payments/processor.ts)

repowise risk

Just-in-time change-risk scoring for a commit or diff range. Scores the defect risk of a change from the same calibrated signals the health layer uses — no LLM calls, and it works without repowise init (pure git + learned constants). The revision defaults to HEAD; pass a base..head range to score a whole branch or PR as one change.

The headline is repo-relative: the change's percentile and review priority (Below typical / Typical / Elevated) within the repo's own recent commits, sampled live. The raw 0–10 model score is still shown, but as a secondary, corpus-anchored number.

repowise risk [REVSPEC] [OPTIONS]

repowise risk                 # score HEAD
repowise risk main..HEAD      # score a branch / PR range as one change
repowise risk --ext .ts,.tsx  # restrict to specific suffixes

Use it in a pre-push hook or CI step to flag high-risk changes before review. For agentic workflows, get_risk exposes the same signals per file plus PR blast-radius analysis.
