v0.1.0 — initial public release

riskcheck v0.1.0

Initial public release of riskcheck — a CLI that quantifies code change risk and outputs structured, explainable results.

go install github.com/hidetzu/riskcheck@latest
riskcheck --base origin/main

Highlights

• Risk score 0–100 computed from git diff and git log, with a clear low / medium / high level
• Explainable: every score comes with concrete reasons
• Per-file risk for AI / reviewer consumption
• Team customization via .riskcheck.yaml (thresholds, weights, paths, test patterns)
• External tool integration for complexity and coverage signals
• Pluggable output: JSON (default) or human-readable text
• CI friendly: exit code reflects risk level (0 = low, 1 = medium+, 2 = error)

Signals (9)

Signal	Description
large_change	Too many files changed
high_insertions	Too many lines added
high_deletions	Too many lines deleted
hotspot	Frequently changed files (last 90 days)
no_test_change	Production code changed without test updates
security_module	Security-related paths modified (auth, crypto, …)
core_module	Core business logic paths modified (config, payment, …)
high_complexity	High cyclomatic complexity (external input)
low_coverage	Low test coverage (external input)

Quick example

$ riskcheck --base origin/main --format text
Risk Score: 55 / 100 (medium)

Files changed: 5
Insertions:    120
Deletions:     30

Reasons:
  - security module modified (src/auth/login.go)
  - no test updates for changed files
  - hotspot file touched (src/auth/login.go changed 8 times in last 90 days)

High-risk files:
  0.75  src/auth/login.go  [hotspot, security_module]
  0.50  src/config/app.go  [core_module]
