Error Recovery

Overview

AI agents get stuck. They try the same approach repeatedly, add complexity to fix complexity, and rationalize "one more attempt" long past the point of diminishing returns. This skill detects stuck patterns proactively and forces recovery before wasted effort compounds.

Core principle: Track every failed attempt. Escalate at defined thresholds. Never allow unbounded retries.

The Prime Directive

NO CONTINUED ATTEMPTS WITHOUT ACKNOWLEDGING FAILURE COUNT

Before EVERY fix attempt, state: "This is attempt N of the current issue." If N >= 3, you are not authorized to continue without user direction.

When to Use

This skill activates automatically when any of these patterns appear:

• Same error message after 2+ attempted fixes
• A fix for problem A introduces problem B
• File edited 3+ times for the same issue without resolution
• Increasing line count or complexity with each attempt
• "Let me try one more thing" after 2+ failures
• Test suite results getting worse, not better
• Reverting a fix and trying a variation of the same approach

This skill overrides optimism. When triggered, it takes priority over whatever strategy is currently failing.

Failure Counter

You MUST maintain an internal failure counter for each distinct issue:

FAILURE LOG
Issue: [description]
Attempt 1: [what you tried] -> [result]
Attempt 2: [what you tried] -> [result]
Attempt 3: [what you tried] -> [result]  <- STOP HERE

Rules:

• Increment the counter for every attempted fix, including "small tweaks"
• A variation of the same approach counts as a new attempt
• Reverting and retrying counts as a new attempt
• The counter resets ONLY when the issue is resolved or the user explicitly resets scope

Severity Levels

Yellow -- 2 Failed Attempts

• Log the concern explicitly: "Two attempts have failed for [issue]."
• Identify what both attempts had in common
• Your next attempt MUST use a fundamentally different approach
• If you cannot identify a different approach, escalate to Orange immediately

Orange -- 3 Failed Attempts

• STOP all fix attempts.
• Step back completely. Re-read the original error from scratch
• Re-analyze the problem as if seeing it for the first time
• List what you know, what you assumed, and what you have not verified
• Formulate a new hypothesis that contradicts your previous assumptions
• Present the situation to the user: "Three attempts have failed. Here is my revised analysis."

Red -- 4+ Failed Attempts

• HALT. Do not continue without explicit user direction.
• Present an honest assessment:

- What you tried (all attempts, briefly) - What you learned from each failure - What you believe the actual problem might be - What you recommend as next steps (including "I may not be able to solve this")

• Wait for user input before proceeding
• If the user says continue, reset to Yellow with the new direction

}

Recovery Strategies

When a fix fails, apply these in order:

1. Re-read the actual error message. Not your interpretation of it -- the literal text. Errors frequently contain the answer.
2. Try a fundamentally different approach. Not a variation. If you were editing config, try code. If you were patching, try replacing. If you were adding, try removing.
3. Simplify ruthlessly. Strip the problem to its smallest reproducible case. Remove everything non-essential. Test the simplest possible version.
4. Verify your assumptions. Print values. Check types. Confirm the file you think you are editing is the one actually being executed. Confirm the function you think is being called is actually being called.
5. Escalate with honesty. Tell the user: "I have tried N approaches. None worked. Here is what I know and what I recommend."
6. Rollback to last known-good state. If you have made things worse, undo all changes and return to where things last worked. Start fresh from there.

Anti-Patterns to Block

These patterns indicate the agent is stuck and MUST trigger this skill:

Cognitive Traps

Guardrails

STOP and activate this skill if you observe:

• You have edited the same file 3+ times for one issue
• Your fix introduced a new failure
• You are writing more code to handle an error than the original feature
• The test suite has more failures now than when you started
• You are suppressing errors or warnings instead of fixing them
• You are about to say "let me try" for the 3rd+ time
• Your solution is more complex than the original problem
• You have been working on the same error for more than 10 minutes of active attempts

Connections

• godmode:fault-diagnosis -- Error recovery activates when fault diagnosis is not converging. If Phase 4 has failed 3+ times, this skill takes over.
• godmode:completion-gate -- After recovery, use completion-gate to verify the fix actually holds. Prevents false "done" claims after a recovery sequence.
• godmode:test-first -- Recovery should include writing a test that reproduces the exact failure. A fix without a regression test is not complete.
• godmode:task-planning -- If recovery reveals the task was scoped wrong, return to task planning to re-scope before continuing.
