Quick Start

1. Capture an Error

./cli/capture-error.sh \
  --agent-id "agent-123" \
  --error-type "TIMEOUT" \
  --message "Agent timed out after 900s" \
  --context "Loop 3 implementation"

2. Batch Errors for Processing

./cli/batch-errors.sh \
  --input errors.json \
  --max-batch-size 5 \
  --output batches.json

3. Log an Error

./cli/log-error.sh \
  --task-id "task-123" \
  --agent-id "agent-123" \
  --error-type "VALIDATION" \
  --message "Output validation failed"

Module Details

Capture Module (lib/capture/)

Purpose: Standardized error capture and categorization

Error Types:

• TIMEOUT - Agent execution timeout
• CRASH - Agent process crash
• VALIDATION - Output validation failure
• COORDINATION - Redis coordination failure (CLI mode only; task-mode default has no Redis)
• UNKNOWN - Uncategorized errors

Features:

• Standardized error format
• Category-based recovery strategies
• Context preservation

Batching Module (lib/batching/)

Purpose: Group errors for batch agent processing

Features:

• Error clustering by file
• Wave calculation for parallel processing
• Tier-based batching (small/medium/large)
• Template-based batch configuration

Logging Module (lib/logging/)

Purpose: Error log storage and management

Features:

• Structured error logging
• Log cleanup and rotation
• Integration with CLI and Docker modes
• TypeScript implementation

---

Integration with CFN Loop

# 1. Capture error when agent fails
./cli/capture-error.sh \
  --agent-id "$AGENT_ID" \
  --error-type "TIMEOUT" \
  --message "$ERROR_MESSAGE"

# 2. Log the error
./cli/log-error.sh \
  --task-id "$TASK_ID" \
  --agent-id "$AGENT_ID" \
  --error-type "TIMEOUT"

# 3. Batch multiple errors for batch processing
./cli/batch-errors.sh --input collected-errors.json
