risk-assess
Uncommitted code risk assessment with breaking change detection, blast radius analysis, and scope metrics. Use when: evaluating PR risk, pre-commit risk check, large refactoring review. Not for: security vulnerabilities (use /codex-security), code correctness (use /codex-review-fast). Output: 3-dimension weighted score + risk level + gate.

Risk Assessment
When NOT to Use
- Security vulnerability detection (use
/codex-security) - Code correctness / lint / test review (use
/codex-review-fast) - Project-level health audit (use
/project-audit)
Procedure
- Run
bash scripts/run-skill.sh risk-assess risk-analyze.js --jsonto collect deterministic scores - Parse the JSON output — overall_score, risk_level, dimensions, flags, gate, next_actions
- If risk_level = Critical (score 75-100) — highlight all breaking signals, recommend splitting PRs
- If risk_level = High (score 50-74) — auto-escalate to
--mode deep, detail blast radius - If risk_level = Medium (score 30-49) — summarize dimensions, note areas of concern
- If risk_level = Low (score 0-29) — brief summary, confirm safe to proceed
- Add qualitative interpretation beyond the scores (e.g., "high blast radius but all dependents are test files")
Script Integration
The script analyzes 3 dimensions + 2 conditional flags:
| Dimension | Weight | What It Measures |
|---|---|---|
| breaking_surface | 45% | Removed exports, renamed APIs, changed signatures, deleted modules |
| blast_radius | 35% | Number of files importing changed modules (grep-based) |
| change_scope | 20% | File count, LOC delta, directory span, rename ratio |
| Flag | Trigger | What It Checks |
|---|---|---|
| migration_safety | Migration/schema files in diff | Rollback/down file exists |
| regression_hint | (v2 stub) | Future: git history analysis |
Scoring Model
- Overall:
breaking_surface * 0.45 + blast_radius * 0.35 + change_scope * 0.20 - Each dimension: 0-100 scale
- Overall: 0-100 scale
Risk Levels
| Score | Level | Gate | Exit Code |
|---|---|---|---|
| 0-29 | Low | PASS | 0 |
| 30-49 | Medium | PASS | 0 |
| 50-74 | High | REVIEW | 1 |
| 75-100 | Critical | BLOCK | 2 |
Script Failure Fallback
If the script fails, report the error and suggest running manually:
bash scripts/run-skill.sh risk-assess risk-analyze.js --json
Output Format
## Risk Assessment Report
| Field | Value |
|-------|-------|
| Score | **[N]/100** |
| Risk Level | [icon] [level] |
| Gate | [PASS/REVIEW/BLOCK] |
### Dimensions
[table of dimension scores + weights]
### Breaking Change Signals
[list of detected signals — only if any]
### Next Actions
[prioritized action items]
## Gate: [sentinel]

Verification
- Script ran successfully
- All 3 dimensions scored
- Qualitative interpretation added beyond raw scores
- Next actions are actionable (include commands where applicable)
- Gate sentinel present in output
