🎯 Repository Quality Improvement Report - Workflow Health Monitoring & Observability

[github-actions[bot]]

Analysis Date: 2026-01-29
Focus Area: Workflow Health Monitoring & Observability
Strategy Type: Custom (Repository-Specific)
Custom Area: Yes - This focus area addresses the unique challenge of monitoring and debugging 198+ agentic workflows running on GitHub Actions with multiple AI engines, MCP servers, and distributed execution patterns.

Executive Summary

This analysis reveals a mature reactive observability system with sophisticated post-execution analysis tools (21,170 LOC across logs/audit commands, 45 test files), comprehensive documentation (1,311-word runbook, 1,687-word debugging skill), but critical gaps in proactive monitoring and real-time visibility. The repository excels at forensic analysis but lacks preventive health checks, live execution monitoring, and trend-based alerting that would catch issues before they impact users.

Key Findings:

• ✅ Excellent: 21,170 LOC observability infrastructure, 53 logs files, 10 audit files, 2.3:1 test coverage
• ✅ Strong: Comprehensive debugging skill and operational runbook for incident response
• ⚠️ Gap: Zero real-time monitoring capabilities (no live tail, watch mode, or streaming)
• ⚠️ Gap: Zero error aggregation across workflows (no errors.Join, users see one error at a time)
• ❌ Critical: No proactive health monitoring (success/failure rates, latency trends, resource usage)
• ❌ Critical: Zero metrics export for external monitoring systems (Prometheus, Datadog, etc.)

Focus Area: Workflow Health Monitoring & Observability

Rationale for This Custom Focus Area

Unlike traditional software projects, gh-aw orchestrates 198+ agentic workflows that:

• Execute autonomously across distributed GitHub Actions runners
• Integrate 84.3% (166/198) MCP servers with varying reliability
• Use multiple AI engines (Copilot, Claude, Codex) with different failure modes
• Process sensitive inputs/outputs through safe-input/safe-output mechanisms
• Run on schedules, webhooks, and manual triggers with varying success rates

This unique architecture requires workflow-specific observability beyond standard application monitoring. Users need to know: Is my workflow healthy? Why did it fail? What's the historical success rate? How can I debug MCP connectivity issues in real-time?

Areas for Improvement

1. Zero Real-Time Monitoring (Critical)

   • No gh aw logs --follow or --tail mode to watch live execution
   • No streaming output as workflows execute
   • Users must wait for completion, then download logs retroactively
   • Impact: 10-30 minute wait to debug failures, no real-time intervention possible

2. No Proactive Health Monitoring (Critical)

   • Zero workflow success/failure rate tracking over time
   • No alerting when success rates drop below thresholds
   • No latency trend analysis (compilation time, execution duration)
   • No resource usage monitoring (memory, CPU, API quotas)
   • Impact: Issues discovered reactively, no early warning system

3. No Error Aggregation (High)

   • Zero errors.Join calls in 21,170 LOC codebase
   • Only 2 []error collection patterns
   • Users see first error, miss subsequent errors in same workflow
   • Impact: Multiple re-runs needed to discover all issues

4. No Metrics Export (High)

   • Zero Prometheus, Datadog, or CloudWatch integration
   • No /metrics endpoint for external monitoring
   • 17 references to "metrics" but no structured export
   • Impact: Cannot integrate with existing monitoring infrastructure

5. Limited Distributed Tracing (Medium)

   • Zero OpenTelemetry or correlation ID propagation
   • Only 1 trace context reference despite distributed execution
   • Run ID tracking exists (257 references) but no cross-service correlation
   • Impact: Hard to trace workflow execution across MCP servers, engines, GitHub API

6. No Structured Logging (Medium)

   • Zero log.WithFields or structured logging calls
   • 49 JSON logging references but not for application logs
   • Debug logs are string-based, hard to parse programmatically
   • Impact: Limited log aggregation and filtering capabilities

7. Minimal Trend Analysis (Medium)

   • Only 3 trend/historical references
   • 594 "aggregate/summary" references but mostly in report formatting
   • No historical success rate dashboard
   • Impact: Cannot identify degrading workflow health over time

🤖 Tasks for Copilot Agent

NOTE TO PLANNER AGENT: The following tasks are designed for GitHub Copilot agent execution. Please split these into individual work items for Claude to process.

Improvement Tasks

The following code regions and tasks should be processed by the Copilot agent. Each section is marked for easy identification by the planner agent.

---

Task 1: Implement Real-Time Log Streaming (gh aw logs --follow)

Priority: High
Estimated Effort: Large
Focus Area: Real-Time Monitoring

Description:
Add real-time log streaming capability to gh aw logs command, enabling developers to watch workflow execution live instead of waiting for completion. This is critical for debugging long-running workflows and enables real-time intervention.

Current Behavior:

• Users run gh aw logs workflow-name and wait for workflow completion
• Logs are downloaded only after workflow finishes
• No visibility into in-progress workflows
• 10-30 minute wait time before debugging can begin

Desired Behavior:

• gh aw logs workflow-name --follow streams logs as workflow executes
• Updates appear in real-time with minimal latency (< 5 seconds)
• Supports filtering options (--error-only, --mcp-only, etc.)
• Gracefully handles workflow completion or user interrupt (Ctrl+C)

Acceptance Criteria:

• Add --follow / -f flag to logs command
• Implement GitHub Actions Logs API polling mechanism (5-10 second intervals)
• Stream new log lines to console as they become available
• Support existing filtering options (--error-only, --json, --verbose)
• Handle workflow completion gracefully (show "Workflow completed" message)
• Handle Ctrl+C interrupt cleanly (cleanup and exit)
• Add progress indicator showing "Waiting for logs..." during poll intervals
• Include unit tests for polling logic and integration tests for end-to-end behavior
• Document usage in debugging skill and CLI reference

Code Region: pkg/cli/logs_command.go, pkg/cli/logs_download.go, pkg/cli/logs_github_api.go

Implementation Notes:

• Use GitHub Actions Logs API with polling (avoid rate limits)
• Store last-read log position to fetch only new lines
• Implement exponential backoff for completed workflows
• Consider using goroutines for non-blocking updates

---

Task 2: Create Workflow Health Dashboard Command (gh aw health)

Priority: High
Estimated Effort: Large
Focus Area: Proactive Health Monitoring

Description:
Create a new gh aw health command that displays workflow success/failure rates, execution trends, and health metrics over time. This proactive monitoring capability will catch degrading workflows before they become critical issues.

Current Behavior:

• No centralized view of workflow health
• Must manually check each workflow's GitHub Actions page
• No historical trend analysis or anomaly detection
• Issues discovered reactively when workflows fail

Desired Behavior:

• gh aw health shows summary of all workflows with success rates
• gh aw health workflow-name shows detailed metrics for specific workflow
• Historical analysis: last 7 days, 30 days, 90 days
• Trend indicators (improving ↑, stable →, degrading ↓)
• Alerting when success rate drops below threshold (default 80%)

Acceptance Criteria:

• Create new health_command.go file following CLI command patterns
• Implement gh aw health (summary view for all workflows)
• Implement gh aw health (workflow-name) (detailed view for one workflow)
• Fetch last 7/30/90 days of workflow runs from GitHub API
• Calculate success rate, failure rate, average duration
• Detect trends (improving, stable, degrading) with visual indicators
• Add --threshold flag to highlight workflows below success rate threshold
• Add --json flag for programmatic consumption
• Support table and JSON output formats
• Include unit tests and integration tests
• Document in CLI reference and create health monitoring guide

Code Region: pkg/cli/health_command.go (new file), pkg/cli/health_metrics.go (new file)

Example Output:

Workflow Health Summary (Last 7 Days)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Workflow                 Success Rate  Trend  Avg Duration
issue-monster.md         100%  (50/50) ↑      2m 30s
code-review.md           94%   (47/50) →      3m 15s
dependency-update.md     78%   (39/50) ↓ ⚠️   5m 45s

⚠️ 1 workflow below 80% success threshold
ℹ Run 'gh aw health (workflow-name)' for details
```

#### Task 3: Add Error Aggregation with `errors.Join`

**Priority**: High  
**Estimated Effort**: Medium  
**Focus Area**: Error Experience Engineering

**Description:**
Implement error aggregation throughout the codebase so users see all validation errors, configuration issues, and workflow problems in one report instead of discovering them one at a time through multiple re-runs.

**Current Behavior:**
- First error stops validation/compilation
- Users fix error, re-run, discover next error
- Requires multiple iterations to fix all issues
- Poor developer experience for workflows with multiple problems

**Desired Behavior:**
- All validation errors collected and reported together
- Clear indication of total error count and severity
- Errors grouped by category (validation, configuration, permissions)
- Users fix all issues in one iteration

**Acceptance Criteria:**
- [ ] Identify validation/compilation code paths that should aggregate errors
- [ ] Replace early returns with error collection using `errors.Join`
- [ ] Update error messages to show "X errors found" and list all
- [ ] Group errors by category for better readability
- [ ] Maintain backward compatibility (exit code 1 if any errors)
- [ ] Add `--fail-fast` flag to restore old behavior if needed
- [ ] Update at least 5 high-traffic validation functions
- [ ] Include unit tests verifying error aggregation
- [ ] Document new behavior in validation guide

**Code Region:** `pkg/workflow/*_validation.go`, `pkg/parser/frontmatter_parser.go`, `pkg/cli/compile_command.go`

**Example Output:**
```
❌ Found 3 validation errors in workflow.md:

Validation Errors (2):
  • Line 5: Invalid engine 'copilot-pro' (valid: copilot, claude, codex, custom)
  • Line 12: Required field 'tools.github' missing when using safe-outputs

Configuration Errors (1):
  • MCP server 'playwright' requires network.allowed_domains configuration

Fix all errors above and re-run compilation.

Task 4: Implement Metrics Export for Prometheus/OpenMetrics

Priority: Medium
Estimated Effort: Large
Focus Area: Observability Infrastructure

Description:
Add Prometheus/OpenMetrics endpoint to gh-aw CLI and GitHub Actions workflows, enabling integration with enterprise monitoring systems like Grafana, Datadog, and CloudWatch.

Current Behavior:

• No metrics export capability
• Cannot integrate with existing monitoring infrastructure
• Metrics trapped in logs and audit reports
• No time-series database for historical analysis

Desired Behavior:

• gh aw metrics serve exposes /metrics endpoint (Prometheus format)
• GitHub Actions jobs emit metrics as custom CloudWatch/Datadog metrics
• Standard metrics: compilation time, test duration, workflow success rate
• Custom metrics: MCP server response time, engine latency, error rates
• Compatible with Grafana dashboards and alerting rules

Acceptance Criteria:

• Add Prometheus Go client library dependency
• Create metrics_command.go with gh aw metrics serve subcommand
• Implement /metrics HTTP endpoint (port 9090 by default)
• Define standard metrics (counters, gauges, histograms)
• Instrument key code paths with metrics collection
• Add --metrics-port flag to customize port
• Document metrics format and labels in reference guide
• Provide example Grafana dashboard JSON
• Include unit tests for metrics collection
• Document CloudWatch/Datadog integration for GitHub Actions

Code Region: pkg/cli/metrics_command.go (new), pkg/metrics/ (new package)

---

Task 5: Add Workflow Health Checks with Automated Alerting

Priority: Medium
Estimated Effort: Medium
Focus Area: Proactive Monitoring

Description:
Implement automated health checks that run periodically and alert when workflow success rates drop below thresholds, MCP servers become unreachable, or execution times degrade significantly.

Current Behavior:

• No automated health monitoring
• Issues discovered when users report failures
• No early warning system for degrading health
• Manual checking required for each workflow

Desired Behavior:

• Automated health checks run every 15/30/60 minutes (configurable)
• Alerts via GitHub Discussions when thresholds breached
• Checks include: success rate, execution time, MCP server availability
• Configurable thresholds per workflow or globally

Acceptance Criteria:

• Create healthcheck_command.go with check definitions
• Implement health check types (success rate, execution time, MCP availability, API quota)
• Create scheduled workflow .github/workflows/health-monitor.yml
• Alert via GitHub Discussions when checks fail
• Support configuration via .github/aw-health-config.yml
• Add --dry-run flag to test checks without alerting
• Include check history in cache for trend analysis
• Write unit tests for each check type
• Document health check configuration in guide

Code Region: pkg/cli/healthcheck_command.go (new), .github/workflows/health-monitor.yml (new)
