# Vercel Deep Management

Comprehensive analysis of Vercel projects, deployments, serverless functions, and edge network.

## Phase 1: Discovery

```bash
#!/bin/bash
TOKEN="${VERCEL_TOKEN}"
TEAM="${VERCEL_TEAM_ID}"
BASE="https://api.vercel.com"
AUTH=(-H "Authorization: Bearer ${TOKEN}")
TEAM_Q=$( [ -n "$TEAM" ] && echo "?teamId=${TEAM}" || echo "")

echo "=== Projects Inventory ==="
curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" \
  | jq -r '.projects[] | "\(.id)\t\(.name)\t\(.framework // "other")\t\(.targets.production.url // "no-deploy")\t\(.updatedAt / 1000 | strftime("%Y-%m-%d"))"' \
  | column -t | head -20

echo ""
echo "=== Project Frameworks ==="
curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" \
  | jq -r '.projects[].framework // "custom"' | sort | uniq -c | sort -rn

echo ""
echo "=== Custom Domains ==="
for PROJ in $(curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" | jq -r '.projects[].name'); do
  curl -s "${BASE}/v9/projects/${PROJ}/domains${TEAM_Q}" "${AUTH[@]}" \
    | jq -r ".domains[] | \"${PROJ}\t\(.name)\t\(.verified)\t\(.redirect // \"none\")\"" 2>/dev/null
done | column -t | head -20

echo ""
echo "=== Environment Variables (counts only) ==="
for PROJ in $(curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" | jq -r '.projects[].name'); do
  COUNT=$(curl -s "${BASE}/v9/projects/${PROJ}/env${TEAM_Q}" "${AUTH[@]}" | jq '.envs | length' 2>/dev/null)
  echo "${PROJ}: ${COUNT:-0} env vars"
done
```

## Phase 2: Analysis

```bash
#!/bin/bash
TOKEN="${VERCEL_TOKEN}"
TEAM="${VERCEL_TEAM_ID}"
BASE="https://api.vercel.com"
AUTH=(-H "Authorization: Bearer ${TOKEN}")
TEAM_Q=$( [ -n "$TEAM" ] && echo "?teamId=${TEAM}" || echo "")
TEAM_AMP=$( [ -n "$TEAM" ] && echo "&teamId=${TEAM}" || echo "")

echo "=== Recent Deployments ==="
curl -s "${BASE}/v6/deployments${TEAM_Q}&limit=20" "${AUTH[@]}" \
  | jq -r '.deployments[] | "\(.name)\t\(.uid[0:8])\t\(.state)\t\(.ready // "pending" | if type == "number" then (. / 1000 | strftime("%Y-%m-%d %H:%M")) else . end)\t\(.target // "preview")"' \
  | column -t | head -20

echo ""
echo "=== Build Performance (last 10 deploys per project) ==="
for PROJ in $(curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" | jq -r '.projects[].name' | head -5); do
  curl -s "${BASE}/v6/deployments?projectId=${PROJ}&limit=10${TEAM_AMP}" "${AUTH[@]}" \
    | jq "[.deployments[] | select(.buildingAt != null and .ready != null) | (.ready - .buildingAt) / 1000] | if length > 0 then {project: \"${PROJ}\", avg_build_s: (add / length | floor), min_s: min, max_s: max} else empty end" 2>/dev/null
done

echo ""
echo "=== Serverless Function Regions ==="
for PROJ in $(curl -s "${BASE}/v9/projects${TEAM_Q}" "${AUTH[@]}" | jq -r '.projects[].name' | head -5); do
  curl -s "${BASE}/v9/projects/${PROJ}${TEAM_Q}" "${AUTH[@]}" \
    | jq "{name, serverlessFunctionRegion: .serverlessFunctionRegion, nodeVersion: .nodeVersion}" 2>/dev/null
done

echo ""
echo "=== Deploy Failure Rate ==="
DEPLOYS=$(curl -s "${BASE}/v6/deployments${TEAM_Q}&limit=50" "${AUTH[@]}")
TOTAL=$(echo "$DEPLOYS" | jq '.deployments | length')
ERRORS=$(echo "$DEPLOYS" | jq '[.deployments[] | select(.state=="ERROR")] | length')
echo "Last 50 deploys: ${ERRORS} failed ($(echo "scale=1; ${ERRORS}*100/${TOTAL}" | bc)% failure rate)"

echo ""
echo "=== Usage & Bandwidth ==="
curl -s "${BASE}/v2/usage${TEAM_Q}" "${AUTH[@]}" \
  | jq '{bandwidth: .bandwidth, builds: .builds, serverlessFunctionExecutions: .serverlessFunctionExecutions}' 2>/dev/null
```

## Safety Rules

- **Read-only**: Only use GET endpoints against the Vercel API
- **Never trigger deployments** or modify projects without explicit confirmation
- **Env vars**: Never output environment variable values, only counts
- **Rate limits**: Vercel API limit is 100 requests per 60 seconds

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |
