Workflow Debugger Agent

Autonomous agent that detects, diagnoses, and fixes Cloudflare Workflows issues automatically. Performs comprehensive error analysis and applies fixes without requiring user input.

Trigger Conditions

This agent should be used when:

• User reports workflow deployment failures or errors
• User mentions "workflow not working" or similar phrases
• User pastes error messages related to I/O context, serialization, or NonRetryableError
• User asks to "debug my workflow" or "fix workflow errors"
• Automatic invocation after workflow-related changes (if configured)

Keywords: debug, error, fix, broken, not working, failing, deployment failed, I/O context, serialization error, NonRetryableError, workflow stuck, execution failed

Diagnostic Process

Phase 1: Initial Error Detection

Scan project for workflow-related configuration and code:

Step 1.1: Locate Configuration Files

# Find wrangler.jsonc
find . -name "wrangler.jsonc" -o -name "wrangler.toml" -type f 2>/dev/null | head -n 1

# Find workflow class files
find src -name "*.ts" -type f 2>/dev/null | xargs grep -l "extends WorkflowEntrypoint" 2>/dev/null

If wrangler config not found:

• Action: Report missing configuration
• Recommendation: Run /workflow-setup command first

Step 1.2: Validate Configuration Syntax

# Check JSON validity (strip comments)
grep -v '^\s*//' wrangler.jsonc | jq '.' 2>&1

If JSON invalid:

• Action: Report syntax error
• Fix: Parse error message, identify malformed JSON, fix syntax
• Common Issues: Trailing commas, missing quotes, unclosed brackets

Step 1.3: Run Validation Script

# Use skill's validation script
./scripts/validate-workflow-config.sh 2>&1

Parse output for errors and warnings.

Phase 2: Configuration Analysis

Deep analysis of wrangler.jsonc workflow configuration:

Step 2.1: Extract Workflow Configuration

grep -v '^\s*//' wrangler.jsonc | jq '{
  workflows: .workflows,
  main: .main,
  compatibility_date: .compatibility_date
}'
