CI Failure Doctor (Copilot)

Performance:

• Runs: 20 | Duration: 3.2h | Tokens: 103K | Cost: $0.00
• Average: 9.6 min/run, 5.1K tokens/run
• 3 cancelled runs, 17 successful

Findings:

• ✅ 85% success rate (17/20)
• ✅ Very low token usage per run
• ✅ Efficient failure diagnosis
• Triggered by workflow_run events on main branch

Firewall Analysis:

• 2,243 requests (620 allowed, 1,623 blocked)
• Heavy use of Copilot APIs
• 257 blocked requests to proxy.golang.org

Daily News (Copilot)

Performance:

• Runs: 5 | Duration: 38.4m | Tokens: 3.3M | Cost: $0.00
• Average: 7.7 min/run, 660K tokens/run

Findings:

• ✅ 100% success rate
• ✅ Consistent performance across runs
• Scheduled daily at 09:00

Smoke Claude (Claude)

Performance:

• Runs: 20 | Duration: 1.9m | Tokens: 0 | Cost: $0.00
• All runs cancelled (intentional)

Findings:

• ⚠️ 30 total errors across cancelled runs
• ℹ️ All failures are dependabot PR cancellations (expected behavior)
• Runs cancelled before agent execution (0 tokens used)
• Not a reliability concern - working as designed

Cost & Efficiency Insights

Claude vs Copilot Cost Comparison:

Engine	Runs	Duration	Tokens	Cost	Avg Cost/Run
Claude	22	2.4h	51.1M	$43.96	$2.00
Copilot	25	3.7h	3.4M	$0.10	$0.00

Key Observations:

• Claude workflows consume 15x more tokens per minute than Copilot
• Claude handles complex refactoring/documentation tasks
• Copilot excels at diagnostic and news aggregation tasks

Top Cost Drivers:

1. Go Logger Enhancement: $21.16 (48% of total cost)
2. Daily Doc Updater: $22.80 (52% of total cost)

Network Firewall Analysis

Overall:

• Total Requests: 4,386
• Allowed: 1,558 (36%)
• Blocked: 2,828 (64%)

Blocked Request Patterns:

• 2,362 requests to "-" (DNS resolution failures or connection attempts)
• 257 requests to proxy.golang.org (expected - Go proxy)
• Several blocked Azure blob storage requests

Top Allowed Domains:

1. api.anthropic.com (852 requests) - Claude API
2. telemetry.enterprise.githubcopilot.com (407 requests)
3. api.enterprise.githubcopilot.com (231 requests)

Recommendations

1. Cost Optimization

High Priority:

• Review Go Logger Enhancement scope: This workflow averages $3.02/run. Consider:
  • Breaking down into smaller, focused tasks
  • Setting token limits or turn count caps
  • Running less frequently if daily refactoring isn't critical

Medium Priority:

• Daily Doc Updater optimization: At $22.80/week ($1,186/year), consider:
  • Caching commit analysis to reduce redundant processing
  • Running on PR merge events instead of daily schedule
  • Implementing incremental doc updates vs full scans

Estimated Savings: $600-900/year by optimizing these two workflows

2. Reliability Improvements

CI Doctor Cancellations:

• 3/20 runs cancelled (15% cancellation rate)
• Investigate cancellation triggers and add retry logic if appropriate

Missing Tool Report:

• Daily Doc Updater reported 1 instance of create_pull_request failing with "No changes to commit"
• Add better change detection before attempting PR creation

3. Performance Monitoring

Establish Baselines:

• Set alerts for runs exceeding:
  • 10 minutes duration (p95: ~11 min currently)
  • 5M tokens/run (p95: ~7M currently)
  • $4/run (p95: ~$4.70 currently)

Track Trends:

• Weekly token consumption trends
• Cost per successful outcome
• Turn count efficiency (tokens/turn ratio)

4. Firewall Optimization

Low Priority:

• 64% of requests blocked (mostly benign)
• proxy.golang.org blocks are expected (Go builds in CI)
• Azure blob storage blocks may indicate failed artifact downloads
  • Investigate if these are causing any workflow issues

Comparison to Previous Week

(Not available - first week of tracking)

Recommended Actions:

1. ✅ Continue this weekly analysis
2. ⚠️ Review Go Logger Enhancement workflow frequency (consider weekly vs daily)
3. ⚠️ Implement token/cost budgets for high-usage workflows
4. ℹ️ Establish performance baseline metrics for trend tracking
