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:

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
