delivery-intel

delivery-intel answers three questions — with evidence, not guesses:

1. Should I trust this repo? (trust score, 6 trust dimensions, 15 forensic signals)
2. Does it ship well and fail safely? (DORA metrics, vulnerability scan, change fail rate)
3. How does it compare? (side-by-side comparison of any two repos)

Every metric shows its source, sample size, and confidence level. No fake precision.

⚡ Quick Start

# Trust verdict — should I adopt this repo? (trust score, dimensions, forensics)
npx delivery-intel facebook/react --mode adopt

# Compare two repos side-by-side
npx delivery-intel --compare facebook/react vercel/next.js

# Full delivery health check (v2 engine)
npx delivery-intel facebook/react --v2

# Classic metrics dump (v1 engine)
npx delivery-intel facebook/react

Why DORA metrics matter

Google's 2024 DORA Report (32,000+ respondents, 10 years of data):

Elite teams are 2× more likely to meet reliability targets and 1.8× more likely to meet business goals (DORA 2024).

Lead Time ★ Elite 3.2 hours median (0.1 days)

Change Failure Rate ● High 4.8% (2 failed / 42 total runs)

◈ Vulnerability Scan (OSV.dev) ──────────────────────────────────────────────────────── ✓ No known vulnerabilities found

◈ Suggestions ──────────────────────────────────────────────────────── ✓ Looking good, no critical issues detected

## What It Measures

| Metric | What it tells you | Source | Confidence |
|--------|-------------------|--------|------------|
| **Deploy Frequency** | How often code ships to production | Deployment statuses → deploys → Actions → PRs | Waterfall |
| **Change Lead Time** | Commit → production (PR flow as fallback) | Deployments + commits | High / Low |
| **Change Fail Rate** | % of deployments that failed or rolled back | Deployment statuses + heuristics | High / Low |
| **Recovery Time** | Time from failure to successful recovery | Deployment failures + workflow runs | High / Low |
| **Pipeline Failure Rate** | CI workflow run reliability (distinct from CFR) | Workflow Runs API | High |
| **Deployment Rework Rate** | Rollback/revert/hotfix rate (inferred) | PR titles + labels + deployment refs | Low (flagged) |
| **Vulnerabilities** | Known CVEs across 7 manifest ecosystems | [OSV.dev](https://osv.dev) batch API | — |
| **Delivery Score** | Confidence-weighted composite (0–100) | All of the above | Aggregate |

> Every metric exposes: data source · sample size · lookback window · confidence level.
> Low-confidence signals contribute less to the composite score — no fake precision.

Supported manifest ecosystems: **npm** · **pip** · **Go modules** · **Poetry** · **pnpm** · **Cargo** · **RubyGems**

## 🔍 Trust Engine

The trust engine (`--mode adopt`) computes a **Trust Score (0–100)** across 6 weighted dimensions, powered by 15 forensic signal detectors:

| Dimension | Weight | Key signals |
|-----------|--------|-------------|
| **Maintenance freshness** | 1.0 | Days since last commit/release, commit cadence |
| **CI reliability** | 0.9 | Pipeline failure rate, CI flakiness across workflows |
| **Vulnerability exposure** | 0.9 | Critical/high CVE density from OSV.dev scan |
| **Release hygiene** | 0.8 | Semver compliance, conventional commits, changelog |
| **Contributor concentration** | 0.8 | Bus factor — single-maintainer risk |
| **Change safety** | 0.7 | Rollback signals, rework density, review latency |

Trust levels: **high** (≥75) · **moderate** (≥45) · **low** (<45) · **insufficient-evidence** (too few signals)

### Compare mode

```bash
npx delivery-intel --compare facebook/react vercel/next.js
npx delivery-intel --compare facebook/react vercel/next.js --json

Runs the trust engine on both repos and produces a structured comparison: per-dimension deltas, metric tier diffs, unique forensic signals, and a winner verdict.

Fix Packs with Trust Gain

Every fix pack now includes a trust gain estimate — how much each fix would improve the trust score:

{
  "id": "fix-missing-dependabot",
  "title": "Enable Dependabot",
  "trustGain": 15,          // estimated trust score improvement
  "rationale": "Automated dependency updates reduce vulnerability exposure..."
}

🔐 Authentication

Token resolution order: --token flag → GITHUB_TOKEN env → gh auth token

Private repos require a token with repo scope. For CI, use ${{ secrets.GITHUB_TOKEN }}. It's auto-scoped and expires per job.

CI Integration

GitHub Actions Marketplace action

The easiest way — use the action directly:

# .github/workflows/delivery-intel.yml
name: Delivery Health Check

on:
  push:
    branches: [main]
  pull_request:

jobs:
  analyze:
    runs-on: ubuntu-latest
    steps:
      - uses: ParthibanRajasekaran/delivery-intel@v1.6.0
        with:
          fail-below: '40'   # fail the job if score drops below 40

Outputs available after the step: score, deploy-frequency, lead-time, change-failure-rate, mean-time-to-restore.

Evidence-backed PR guardrail (v2 engine)

Posts a policy-aware comment on every PR — no block unless a real threshold is breached:

    steps:
      - name: Delivery Health Check
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          npx delivery-intel@latest ${{ github.repository }} \
            --v2 \
            --pr-comment \
            --fail-below 40 \
            --no-spinner

      - name: Post PR Comment
        if: always() && github.event_name == 'pull_request'
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          gh pr comment ${{ github.event.pull_request.number }} \
            --body-file delivery-intel-pr-comment.md \
            --repo ${{ github.repository }}

The comment leads with a verdict (✅ No block / ⚠️ Warning / 🚫 BLOCKED), followed by a collapsible metrics table with source and confidence for every data point.

npx (custom pipeline)

    steps:
      - name: Run delivery-intel
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: npx delivery-intel@latest ${{ github.repository }} --v2 --json --output report.json

      - name: Check health score
        run: |
          SCORE=$(jq '.scores.delivery.score' report.json)
          echo "Health score: $SCORE / 100"
          if (( $(echo "$SCORE < 40" | bc -l) )); then
            echo "::error::Score $SCORE is below threshold (40)"
            exit 1
          fi

🏅 Badge

Once you have the dashboard deployed, you can show a live delivery score in any README:

[![Delivery Score](https://your-deployment-url/api/badge?repo=owner/repo)](https://github.com/ParthibanRajasekaran/delivery-intel)

The GET /api/badge?repo=owner/repo endpoint returns a Shields.io endpoint-badge payload. Score maps to color: < 20 red → < 40 orange → < 60 yellow → < 80 green → ≥ 80 bright green. Results cached 5 minutes.

Self-hosting: deploy the dashboard (npm run build && npm start or docker compose up dashboard) and replace your-deployment-url.
