Error Recovery 🚨

4R framework. Never lose work silently.

The 4 Rs

R1: RECOGNIZE  → Did something go wrong?
R2: RESCUE     → Can I recover automatically?
R3: REPORT     → Does the human need to know?
R4: REMEMBER   → What should I learn from this?

R1: RECOGNIZE (Don't Ignore Errors)

Error signals I must not ignore:

□ Command exit code ≠ 0
□ Exception thrown
□ Timeout exceeded
□ Empty/unexpected output
□ "error", "failed", "exception" in logs
□ Behavior different from expected

Anti-patterns:

• ❌ Command failed, but I continue anyway
• ❌ Error logged, but not mentioned in my response
• ❌ "Probably fine" without verification

What to do:

1. Stop and acknowledge the error
2. Read the full error message
3. Check if it's recoverable or needs human input

R2: RESCUE (Can I Fix It?)

Automatic recovery strategies:

Error Type	Recovery Strategy
Network timeout	Retry with exponential backoff (max 3)
Rate limit	Wait and retry
Missing dependency	Install/suggest installation
Permission denied	Suggest elevated permissions or fix
File not found	Create or point to correct path
Invalid input	Sanitize or request correct input
API error	Check status, retry if transient

Retry protocol:

Attempt 1: Immediate
Attempt 2: Wait 5 seconds
Attempt 3: Wait 15 seconds
If all fail → Report to human

When NOT to auto-retry:

• Authentication errors (wrong credentials)
• Permission errors (needs human action)
• Data validation errors (needs correct input)
• Destructive operation failures (don't risk double-execution)

R3: REPORT (Does Human Need to Know?)

Always report when:

• Auto-recovery failed after 3 attempts
• Error affects the final outcome
• Human action is required
• Something unexpected happened

Report format:

⚠️ Error encountered: [brief description]

What happened:
[What I was doing]

Error details:
[Full error message]

What I tried:
[Recovery attempts made]

Current state:
[What's broken / what's still working]

What I need:
[What human action is needed, if any]

Example:

⚠️ Error encountered: GitHub push failed

What happened:
Pushing to aptratcn/cognitive-debt-guard

Error details:
fatal: could not read Username for 'https://github.com'

What I tried:
1. Retried push (failed)
2. Checked git remote config

Current state:
- Commit is saved locally
- Not pushed to remote

What I need:
Git credentials not configured. Will try using token auth.

R4: REMEMBER (Learn From Errors)

After error recovery:

□ Did this error happen before?
  → If yes, what's the pattern?
  → Document the fix

□ Could this happen again?
  → Add guard for this case
  → Update skill/workflow

□ Is there a systemic issue?
  → Suggest process improvement
  → Update AGENTS.md if needed

Error log:

memory/errors/YYYY-MM-DD.md

## [Error Type] - [Timestamp]

**Context:** What I was doing
**Error:** Full error message
**Cause:** Root cause (if known)
**Fix:** How I resolved it
**Prevention:** How to avoid in future

Quick Reference

ERROR → STOP → READ ERROR → CAN I FIX?
                                 ↓
        NO → REPORT to human → WAIT for action
        YES → FIX → VERIFY → CONTINUE
                      ↓
                   Still broken? → REPORT

Trigger Phrases

• "error", "failed", "crash"
• "something went wrong", "exception"
• "retry", "try again"
• "报错", "失败", "错误"

Integration

• EVR Framework — Verify after recovery
• Systematic Debugging — When root cause is unknown
• Workflow Checkpoint — Save state before risky operations
